65 00:04:58,290 --> 00:05:01,950 The capabilities of a fixed -wing aircraft and the capabilities of a 66 00:05:01,950 --> 00:05:02,950 are completely different. 67 00:05:03,390 --> 00:05:06,710 Combining those capabilities into a single airframe is particularly 68 00:05:07,610 --> 00:05:11,970 How do you keep the aircraft under control while it shapeshifts in midair? 69 00:05:13,290 --> 00:05:17,150 You have centers of gravity shifting, you're operating at different speeds. 70 00:05:17,470 --> 00:05:20,630 so the characteristics of this aircraft are constantly changing. 71 00:05:21,810 --> 00:05:26,190 And how do you stow a giant aircraft in the cramped spaces on board transport 72 00:05:26,190 --> 00:05:27,190 ships? 73 00:05:28,530 --> 00:05:33,210 So we have to be able to fit a high number of V -22s onto our amphibious 74 00:05:33,210 --> 00:05:36,930 shipping, so it's important that we can fold it and fit it into tight spaces. 75 00:05:42,190 --> 00:05:44,330 Operated by a crew of four Marines. 76 00:05:45,960 --> 00:05:48,780 The Osprey accomplishes all this and more. 77 00:05:51,180 --> 00:05:58,000 It's powered by a pair of Rolls -Royce engines that can propel it over 300 78 00:05:58,000 --> 00:05:59,000 per hour. 79 00:06:00,620 --> 00:06:05,400 A top speed more than 50 % greater than the planet's fastest helicopter. 80 00:06:13,710 --> 00:06:17,470 The fighting Griffins are making their final preparations before taking to the 81 00:06:17,470 --> 00:06:19,090 skies on today's training flight. 82 00:06:22,110 --> 00:06:29,090 But this military exercise is only possible thanks to some of 83 00:06:29,090 --> 00:06:32,710 the most groundbreaking aviation engineering the world has ever seen. 84 00:06:36,040 --> 00:06:40,980 Responsible for a few world firsts, this revolutionary aircraft never fails to 85 00:06:40,980 --> 00:06:45,320 amaze Osprey engineer Rod Olson. The Osprey is designed to take off like a 86 00:06:45,320 --> 00:06:47,360 helicopter and fly like a fixed -wing aircraft. 87 00:06:47,600 --> 00:06:49,600 It then lands like a helicopter as well. 88 00:06:50,220 --> 00:06:53,740 The capabilities of a fixed -wing aircraft and the capabilities of a 89 00:06:53,740 --> 00:06:54,740 are completely different. 90 00:06:55,220 --> 00:06:58,560 Combining those capabilities into a single airframe is particularly 91 00:06:58,560 --> 00:07:01,620 because you have to balance design requirements in order to achieve an 92 00:07:01,620 --> 00:07:02,620 solution. 93 00:07:03,850 --> 00:07:07,870 Mechanics and physics involved in solving the transition between 94 00:07:07,870 --> 00:07:09,710 and airplane mode are particularly complex. 95 00:07:11,450 --> 00:07:16,470 In order to solve this problem, engineers can look to history's 96 00:07:16,470 --> 00:07:17,470 inspiration. 97 00:07:20,810 --> 00:07:26,070 At the National Museum of the U .S. Air Force in Dayton, Ohio, aerospace 98 00:07:26,070 --> 00:07:30,270 engineer Lynn Pickering has traveled to see a game -changing experimental 99 00:07:30,270 --> 00:07:31,270 aircraft. 100 00:07:33,710 --> 00:07:37,190 Oh my gosh, look at this thing. 101 00:07:37,490 --> 00:07:40,230 It looks like it's straight out of a sci -fi film. 102 00:07:41,670 --> 00:07:43,490 This is the Bell XVIII. 103 00:07:43,850 --> 00:07:45,930 It's the only one left of its kind. 104 00:07:46,370 --> 00:07:50,670 I would have to say this is one of the most exciting pieces of aviation 105 00:07:50,670 --> 00:07:52,730 engineering that I've ever, ever seen. 106 00:07:54,890 --> 00:08:00,990 Making its maiden flight in 1955, the XVIII is a true pioneer of aviation 107 00:08:00,990 --> 00:08:01,990 engineering. 108 00:08:03,740 --> 00:08:07,760 developed as part of a joint research program between the United States Air 109 00:08:07,760 --> 00:08:08,760 Force and Army. 110 00:08:10,320 --> 00:08:15,400 The experimental concepts introduced on the XV -3 laid the foundation that 111 00:08:15,400 --> 00:08:16,920 helped make the Osprey possible. 112 00:08:23,660 --> 00:08:28,720 This aircraft is actually the first attempt at tilt rotor technology. 113 00:08:29,080 --> 00:08:35,490 And so what that means is that... This is in helicopter formation now, but when 114 00:08:35,490 --> 00:08:41,669 the aircraft takes off, these blades rotate down into airplane mode. And then 115 00:08:41,669 --> 00:08:45,990 when the aircraft needs to land again, they rotate back up, lands like a 116 00:08:45,990 --> 00:08:46,990 helicopter. 117 00:08:48,030 --> 00:08:52,730 These cleverly designed rotor blades allowed for a previously unprecedented 118 00:08:52,730 --> 00:08:53,730 -air switch. 119 00:08:54,350 --> 00:08:55,670 This is wild. 120 00:08:55,890 --> 00:08:56,890 You'd think that. 121 00:08:56,940 --> 00:09:01,120 Something like this should be impossible, that you take off like a 122 00:09:01,120 --> 00:09:05,200 and then you transform kind of like a transformer, and then you're flying like 123 00:09:05,200 --> 00:09:09,800 an airplane. So it's always been a bit of a holy grail for aviation engineers. 124 00:09:11,660 --> 00:09:16,480 Leading the quest to realize this ambition were Bell designers Bob Lichten 125 00:09:16,480 --> 00:09:17,480 Kenneth Wernicke. 126 00:09:20,800 --> 00:09:25,320 I just think of how daunting this must have been to design something like this. 127 00:09:25,760 --> 00:09:30,660 When you're trying to combine those two concepts into one airframe, you run into 128 00:09:30,660 --> 00:09:31,660 a lot of issues. 129 00:09:34,640 --> 00:09:40,440 And during a test flight in 1956, the XV -3 would demonstrate just how difficult 130 00:09:40,440 --> 00:09:42,800 it is to perfect tilt rotor technology. 131 00:09:45,120 --> 00:09:50,320 After the aircraft suffered extreme vibrations in midair, the pilot passed 132 00:09:50,500 --> 00:09:52,000 causing the prototype to crash. 133 00:09:54,020 --> 00:09:58,180 To solve this problem, engineers needed to go back to the drawing board. 134 00:10:01,860 --> 00:10:06,520 So if we look at the wings, we can actually see one of the key design 135 00:10:06,520 --> 00:10:08,600 after that first crash. 136 00:10:08,840 --> 00:10:13,800 Their solution changed aviation forever and provided the groundwork for the V 137 00:10:13,800 --> 00:10:16,040 -22 Osprey to rule the skies. 138 00:10:16,540 --> 00:10:21,060 The technology demonstrated by the V -22 is really a long time coming and the 139 00:10:21,060 --> 00:10:23,020 result of multiple decades of engineering. 140 00:10:26,890 --> 00:10:32,110 The V -22 Osprey is a unique military aircraft with unrivaled capabilities. 141 00:10:34,110 --> 00:10:40,850 Equipped with a pair of transformational tilt rotors, the Osprey can convert 142 00:10:40,850 --> 00:10:47,490 between flight modes in just 12 seconds, allowing it to take off, 143 00:10:47,730 --> 00:10:53,770 hover, and land like a helicopter, and fly at high speed and altitude like an 144 00:10:53,770 --> 00:10:54,770 airplane. 145 00:10:56,780 --> 00:11:01,160 To make this mighty machine possible, engineers needed to learn from the 146 00:11:01,160 --> 00:11:02,700 and errors of their predecessors. 147 00:11:03,700 --> 00:11:09,560 The Bell XV3 was the first aircraft to utilize tilt rotor technology, but their 148 00:11:09,560 --> 00:11:12,460 test flight revealed a catastrophic vibration issue. 149 00:11:13,740 --> 00:11:18,320 Having realized the flaw in their design, Bell's engineers set out to find 150 00:11:18,320 --> 00:11:19,320 solution. 151 00:11:19,790 --> 00:11:24,390 So if we look at the wings, we can actually see one of the key design 152 00:11:24,390 --> 00:11:26,470 after that first crash. 153 00:11:26,970 --> 00:11:33,950 They've added these struts in here to make these wings a lot stronger, and 154 00:11:33,950 --> 00:11:38,550 that changed the whole frequency of the structure so that it no longer is going 155 00:11:38,550 --> 00:11:41,330 to resonate with the tilt rotor tilting down. 156 00:11:42,190 --> 00:11:45,290 And let me show you another aspect of the design change. 157 00:11:45,660 --> 00:11:50,280 They actually changed from a three -blade design up here to two blades. 158 00:11:50,580 --> 00:11:57,400 And they strengthened and shortened this pylon here on both sides to make 159 00:11:57,400 --> 00:11:59,460 this stronger and decrease the vibrations. 160 00:11:59,920 --> 00:12:04,880 And then inside this fairing here, we've actually got the electrical motor that 161 00:12:04,880 --> 00:12:10,860 completes this 90 -degree arc in only 10 to 15 seconds. So very quickly, you're 162 00:12:10,860 --> 00:12:14,280 able to go from helicopter mode to prop plane mode. 163 00:12:17,000 --> 00:12:22,660 After incorporating its new design elements, the XV -3 successfully 164 00:12:22,660 --> 00:12:28,820 problems, completing more than 100 full conversions of its tilt rotors between 165 00:12:28,820 --> 00:12:35,520 1958 and 1962, making it the first aircraft to achieve a feat 166 00:12:35,520 --> 00:12:37,820 engineers had long thought impossible. 167 00:12:39,440 --> 00:12:44,700 The XV -3 might just be one of the most important pieces of aviation 168 00:12:44,700 --> 00:12:50,230 engineering. It really took this concept of combining these two technologies, 169 00:12:50,230 --> 00:12:55,190 which a lot of people thought was going to be impossible, and they proved that 170 00:12:55,190 --> 00:12:56,190 it was possible. 171 00:13:11,390 --> 00:13:13,110 Back on board the Osprey. 172 00:13:19,880 --> 00:13:23,440 Today's expert flight crew is about to embark on their scheduled training 173 00:13:23,440 --> 00:13:26,460 mission, which will test the aircraft's unique faculties. 174 00:13:31,400 --> 00:13:36,740 Just like the XV -3, the Osprey uses its rotors in the upright position to take 175 00:13:36,740 --> 00:13:37,740 off vertically. 176 00:13:41,130 --> 00:13:46,350 then pivots them forward by 90 degrees, allowing the wings to generate lift, 177 00:13:46,590 --> 00:13:51,970 completing the conversion to propeller plane in a little over 12 seconds. 178 00:13:58,110 --> 00:14:02,670 Osprey engineer Rod Olson knows just what it takes to make this remarkable 179 00:14:02,670 --> 00:14:07,990 possible. The secrets behind the incredible tilt rotor technology are 180 00:14:07,990 --> 00:14:12,080 inside the structures on the aircraft's wingtips. known as nacelles. 181 00:14:13,780 --> 00:14:17,420 So contained within the nacelle, there are several components that allow it to 182 00:14:17,420 --> 00:14:20,380 operate. Primarily the engines, which are in this lower portion. 183 00:14:20,680 --> 00:14:24,600 Then there are gearboxes further up, drivetrains, and ultimately the rotor 184 00:14:24,600 --> 00:14:25,600 system here at the tip. 185 00:14:25,900 --> 00:14:29,620 The pylon conversion actuator is responsible for actually moving the 186 00:14:29,620 --> 00:14:30,199 and down. 187 00:14:30,200 --> 00:14:33,340 It has dual redundancy, so in the event of a failure, the pylon conversion 188 00:14:33,340 --> 00:14:36,560 actuator can actually allow the aircraft to land safely. 189 00:14:38,830 --> 00:14:43,790 The pylon conversion actuator is a hydraulically powered telescopic ball 190 00:14:45,150 --> 00:14:51,850 As the screw is rotated, it extends and rotates a lug that is 191 00:14:51,850 --> 00:14:57,350 coupled to the nacelle, causing it to pivot from the vertical to horizontal 192 00:14:57,350 --> 00:14:58,350 orientation. 193 00:14:59,450 --> 00:15:05,330 When the screw is rotated in the opposite direction, the nacelle returns 194 00:15:05,330 --> 00:15:06,330 vertical orientation. 195 00:15:08,880 --> 00:15:12,160 If you look at the nacelle and the tiltrotor, you can see just how 196 00:15:12,160 --> 00:15:13,680 the engineering is that went into this. 197 00:15:13,980 --> 00:15:16,680 The tiltrotor technology employed on the Osprey is unique. 198 00:15:17,020 --> 00:15:19,420 It does not use anywhere else in the world in an operational status. 199 00:15:21,680 --> 00:15:26,000 Surprisingly, all it takes for Osprey pilots like Major Thomas Cecil to carry 200 00:15:26,000 --> 00:15:29,580 out this incredible transformation is the push of a single switch. 201 00:15:32,170 --> 00:15:36,930 The V -22 makes a transition from helicopter mode to airplane mode with 202 00:15:36,930 --> 00:15:38,430 just the flick of the thumb. 203 00:15:38,710 --> 00:15:43,810 On our TCL down here, we have a nacelle thumb wheel, and all we have to do is 204 00:15:43,810 --> 00:15:47,070 push forward on the thumb wheel, and it begins to actuate the nacelle forward 205 00:15:47,070 --> 00:15:48,070 towards airplane mode. 206 00:15:51,190 --> 00:15:55,910 So when I push forward on the nacelle thumb wheel, it's going to actuate 207 00:15:55,910 --> 00:15:59,830 conversion actuators on either wingtip and... 208 00:16:00,440 --> 00:16:04,140 Through the conversion actuators, it'll modulate the nacelles down. 209 00:16:05,820 --> 00:16:11,160 When we're ready to convert again and come back to VTOL, it's just a reverse 210 00:16:11,160 --> 00:16:16,300 process. We'll pull back on the nacelle thumb wheel, and we revert back to 211 00:16:16,300 --> 00:16:18,200 typical helicopter -style controls. 212 00:16:19,520 --> 00:16:24,000 It's a groundbreaking achievement that's only possible thanks to the Osprey's 213 00:16:24,000 --> 00:16:25,940 innovative aviation ancestors. 214 00:16:28,240 --> 00:16:32,660 The technology demonstrated by the V -22 is really a long time coming and the 215 00:16:32,660 --> 00:16:34,620 results of multiple decades of engineering. 216 00:16:35,040 --> 00:16:38,380 And it all starts and is all built off other aircraft. 217 00:16:42,240 --> 00:16:49,000 Back in the sky, 266 Squadron is underway on a training exercise 218 00:16:49,000 --> 00:16:54,640 designed to simulate the challenges of a complex real -world military operation. 219 00:16:58,060 --> 00:16:59,960 Copy, 80 feet, all calls in the back. 220 00:17:00,300 --> 00:17:01,300 Roger, clear right. 221 00:17:04,720 --> 00:17:09,520 With the Marines regularly deployed in the planet's most hostile locations, 222 00:17:09,520 --> 00:17:12,079 essential that the Osprey can get them there safely. 223 00:17:14,319 --> 00:17:20,980 And that means being able to land 224 00:17:20,980 --> 00:17:22,760 in low -visibility conditions. 225 00:17:35,160 --> 00:17:38,340 We have to be able to take this aircraft into any environment. 226 00:17:38,640 --> 00:17:42,800 And because of the amount of downwash that we create, we have to be ready for 227 00:17:42,800 --> 00:17:45,320 dust, sand, snow, anything. 228 00:17:45,560 --> 00:17:48,600 And that's going to reduce our visibility when coming into land. 229 00:17:53,350 --> 00:17:57,670 Losing visibility during a landing is extremely dangerous. If you can imagine 230 00:17:57,670 --> 00:18:02,050 pulling into your driveway with your eyes closed while you're driving your 231 00:18:02,210 --> 00:18:06,590 you just trust yourself to just stop before you crash into your garage door. 232 00:18:06,890 --> 00:18:13,550 But in this case, we have maybe up to 25, 27 people's lives on the line 233 00:18:13,550 --> 00:18:15,970 and very expensive equipment. 234 00:18:16,870 --> 00:18:21,050 If we were to crash an aircraft, that right there is mission failure. 235 00:18:21,680 --> 00:18:26,280 So it's very important that we're able to take off and land in a reduced 236 00:18:26,280 --> 00:18:27,380 visibility environment. 237 00:18:30,820 --> 00:18:34,680 Incredibly, engineers have come up with a solution that allows the Osprey to 238 00:18:34,680 --> 00:18:38,860 operate in zero visibility, helping pilots avoid disaster. 239 00:18:40,520 --> 00:18:43,400 We have a couple different ways that we can do this. 240 00:18:43,640 --> 00:18:48,420 One is through an automated approach, which is pre -built into our flight plan 241 00:18:48,420 --> 00:18:50,820 to assist the pilot to make a safe landing. 242 00:18:51,260 --> 00:18:55,000 We're really talking about the very final stages before landing, and this is 243 00:18:55,000 --> 00:18:57,340 where we're going to lose our visibility outside. 244 00:19:00,160 --> 00:19:05,980 By using GPS technology to identify a suitable landing location, the Osprey 245 00:19:05,980 --> 00:19:10,480 control its drift and rate of descent to safely touch down without any input 246 00:19:10,480 --> 00:19:11,480 from the pilot. 247 00:19:13,100 --> 00:19:17,580 And the aircraft's high -tech instrumentation can also be used to 248 00:19:17,580 --> 00:19:19,980 landing when loss of visibility is not expected. 249 00:19:22,250 --> 00:19:27,790 We can also use automation on the fly, and we engage that utilizing the flight 250 00:19:27,790 --> 00:19:28,749 director panel. 251 00:19:28,750 --> 00:19:33,350 The primary piece that we're looking at here is the hover coupler, and utilizing 252 00:19:33,350 --> 00:19:38,450 this is going to give us varying degrees of lateral control assistance to 253 00:19:38,450 --> 00:19:42,710 minimize drift. It's also going to help us slow the aircraft down and give us a 254 00:19:42,710 --> 00:19:43,750 controlled rate of descent. 255 00:19:43,950 --> 00:19:48,390 When we're ready to land, we can just engage basically the altitude control, 256 00:19:48,390 --> 00:19:50,330 then we control the altitude and rate of descent. 257 00:19:51,400 --> 00:19:55,920 It's an amazing solution that's essential to allow the Osprey to land in 258 00:19:55,920 --> 00:19:59,060 world's most hostile locations in zero visibility. 259 00:20:00,740 --> 00:20:05,000 It's just not possible without this system and without these displays that 260 00:20:05,000 --> 00:20:10,320 have. The team has devised a one -of -a -kind multimodal aircraft capable of an 261 00:20:10,320 --> 00:20:14,980 amazing transformation, but engineers now face the problem of how to keep it 262 00:20:14,980 --> 00:20:16,860 stable while it morphs in midair. 263 00:20:17,860 --> 00:20:21,400 There's a lot of challenges with operating in conversion mode. 264 00:20:21,660 --> 00:20:23,700 In order to land, we have to slow down. 265 00:20:24,020 --> 00:20:25,200 This involves converting. 266 00:20:25,680 --> 00:20:29,760 And as we do, this changes the configuration of the aircraft and brings 267 00:20:29,760 --> 00:20:32,260 different handling characteristics into play. 268 00:20:32,880 --> 00:20:37,700 To help keep the Osprey stable through this unique conversion process, 269 00:20:37,700 --> 00:20:40,300 must look to the pioneers of the past. 270 00:20:41,120 --> 00:20:42,260 All right, you ready to go? 271 00:20:42,520 --> 00:20:43,520 Yeah, man, let's go fly it. 272 00:20:52,469 --> 00:20:55,650 Engineer Dan Dickrell has traveled to the heart of Georgia. 273 00:20:57,530 --> 00:20:59,670 Oh, I can't wait to see this. 274 00:20:59,930 --> 00:21:01,170 This is going to be awesome. 275 00:21:02,070 --> 00:21:04,910 To discover a plane with a trailblazing design. 276 00:21:07,370 --> 00:21:08,610 Dang, look at that. 277 00:21:10,070 --> 00:21:12,950 What a beautiful and shiny aircraft. 278 00:21:13,470 --> 00:21:19,690 It's a Lockheed Electra 12. It's a classic example of Art Deco era of 279 00:21:20,140 --> 00:21:24,020 There's only about 10 of these left in the world, and today I get to fly one. 280 00:21:24,840 --> 00:21:30,060 First taking flight in 1936, the Lockheed Model 12 Electra Jr. 281 00:21:30,500 --> 00:21:32,540 is a pioneer of passenger aviation. 282 00:21:33,780 --> 00:21:38,800 And it holds the key to keeping the V -22 Osprey stable as it transitions 283 00:21:38,800 --> 00:21:41,560 between helicopter and airplane in midair. 284 00:21:42,920 --> 00:21:46,840 All right, seven lakes in traffic, Lockheed, departing runway 18, seven 285 00:21:47,990 --> 00:21:52,450 Building on the success of the Model 10 that went into production two years 286 00:21:52,450 --> 00:21:59,090 earlier, the Electra family of aircraft was famous for its forward -thinking all 287 00:21:59,090 --> 00:22:03,430 -metal construction and the early adoption of twin engines. 288 00:22:03,710 --> 00:22:04,710 All right, you ready to go? 289 00:22:04,910 --> 00:22:05,910 Yeah, man, let's go flying. 290 00:22:26,770 --> 00:22:31,270 And as Dan is about to discover, the Electra is an aircraft that's remarkably 291 00:22:31,270 --> 00:22:32,310 easy to handle. 292 00:22:37,630 --> 00:22:44,470 But in the early days of the Electra's 293 00:22:44,470 --> 00:22:49,110 development, a flaw was discovered in one of its key components, a defect that 294 00:22:49,110 --> 00:22:50,990 threatened to keep the airplane grounded. 295 00:22:52,560 --> 00:22:57,260 aircraft control one of the primary control services is the rudder the tail 296 00:22:57,260 --> 00:23:01,820 that's the part that allows the plane to yaw in the sky go left and right so 297 00:23:01,820 --> 00:23:06,140 much like the steering wheel in a car allows the car to turn left and right i 298 00:23:06,140 --> 00:23:12,360 have two pedals on the floor that i have my feet on and if i press the left 299 00:23:12,360 --> 00:23:19,220 rudder pedal in strongly there we go it turns to the left and if i press 300 00:23:19,220 --> 00:23:21,700 my right pedal in 301 00:23:22,410 --> 00:23:25,350 We go to the right a little bit. There we go. 302 00:23:27,550 --> 00:23:28,610 Those are the basics. 303 00:23:29,710 --> 00:23:33,910 Initially designed with a single tail positioned in the center of the 304 00:23:34,390 --> 00:23:38,450 wind tunnel tests showed the Electra was vulnerable to instability in flight. 305 00:23:39,990 --> 00:23:44,510 This is obviously a problem, especially if you're trying to design a passenger 306 00:23:44,510 --> 00:23:48,830 plane. So the engineers knew that they had to solve this in order for this 307 00:23:48,830 --> 00:23:49,970 aircraft to be successful. 308 00:23:51,370 --> 00:23:54,110 The solution came from an unexpected source, 309 00:23:54,950 --> 00:23:59,170 Clarence Kelly Johnson, a student working on the Electra program. 310 00:23:59,970 --> 00:24:03,930 So Johnson realized the problem with the prototype stability came down to the 311 00:24:03,930 --> 00:24:04,930 single tail. 312 00:24:05,030 --> 00:24:09,090 And his solution was this, a twin tail design. 313 00:24:09,990 --> 00:24:14,990 This simple design tweak was a game changer for the Electra, and it solved 314 00:24:14,990 --> 00:24:17,070 prototype stability problems for good. 315 00:24:18,640 --> 00:24:22,200 The reason why the twin tail works as well as it does comes down to placement. 316 00:24:22,520 --> 00:24:26,820 If you can see, the propeller on this side of the aircraft is almost in line 317 00:24:26,820 --> 00:24:31,200 with the tail, right? The reason why that helps is because the slipstream 318 00:24:31,200 --> 00:24:35,640 coming off of this propeller is in a position where it can interact with the 319 00:24:35,640 --> 00:24:40,000 control service, this rudder. And remember, a rudder helps the airplane 320 00:24:40,000 --> 00:24:41,080 or right in the air. 321 00:24:41,630 --> 00:24:45,910 in situations where there's low speed either on takeoff or landing the ability 322 00:24:45,910 --> 00:24:51,310 of this control service to safely move the airplane around is most important 323 00:24:51,310 --> 00:24:55,890 that's one of the upsides of this design versus a single tail single tail can't 324 00:24:55,890 --> 00:25:00,190 take advantage of that alignment and that increased airflow and so that's why 325 00:25:00,190 --> 00:25:05,010 this twin tail works as well as it does additionally since there's two tails 326 00:25:05,010 --> 00:25:10,900 there's twice the area twice the area you have much more control authority to 327 00:25:10,900 --> 00:25:13,580 maneuver this plane in the air. It's a brilliant solution. 328 00:25:27,540 --> 00:25:33,560 Over 85 years after Johnson introduced the twin tail on the Electra, the 329 00:25:33,560 --> 00:25:36,240 pilots utilized the same innovative concept. 330 00:25:37,680 --> 00:25:41,900 The twin tail is what gives us aircraft that directional stability when we're 331 00:25:41,900 --> 00:25:43,160 operating in airplane mode. 332 00:25:44,340 --> 00:25:49,540 On each vertical stabilizer, it has a rudder. Those rudders are both actuated 333 00:25:49,540 --> 00:25:52,140 utilizing the pedals on the floor of the cockpit. 334 00:25:52,360 --> 00:25:55,680 And we use that to control and make directional control inputs. 335 00:25:56,170 --> 00:26:01,310 Also in between our two vertical stabilizers, we have the horizontal 336 00:26:01,310 --> 00:26:05,690 with the elevator, which is this giant kind of whale tail, which you see. And 337 00:26:05,690 --> 00:26:07,910 that gives us longitudinal control. 338 00:26:09,650 --> 00:26:14,470 As with the Electra, the Osprey's use of this tail technology is key for 339 00:26:14,470 --> 00:26:16,490 ensuring a smooth flight experience. 340 00:26:18,150 --> 00:26:20,290 We have to have a certain amount of stability. 341 00:26:20,730 --> 00:26:24,850 Without the twin tails, those aircraft would be much, much harder to fly. 342 00:26:29,450 --> 00:26:33,730 And this stabilizing innovation is also involved in steadying the aircraft 343 00:26:33,730 --> 00:26:35,970 through its challenging conversion process. 344 00:26:37,410 --> 00:26:42,110 The twin tail makes it possible for this aircraft to transition between airplane 345 00:26:42,110 --> 00:26:43,610 and VTOL. 346 00:26:44,170 --> 00:26:50,690 When we're an airplane, all of our controls are... actuated similar to any 347 00:26:50,690 --> 00:26:55,410 airplane. And then as we move towards VTOL, everything is made through the 348 00:26:55,410 --> 00:26:57,950 similar control inputs to what you would see with a helicopter. 349 00:26:58,290 --> 00:27:00,850 In between, it's a combination of the two. 350 00:27:01,530 --> 00:27:03,250 And converting to helicopter mode. 351 00:27:08,270 --> 00:27:13,910 So as we transition from airplane -type control inputs towards helicopter -type 352 00:27:13,910 --> 00:27:19,310 control inputs, it's a blend utilizing the tail, whether it be the elevator, 353 00:27:19,310 --> 00:27:23,790 rudders, combined with inputs through the prop rotors to achieve for the 354 00:27:23,790 --> 00:27:25,750 output and control that we require. 355 00:27:29,670 --> 00:27:34,730 It's an ingenious modern use of this historic technology that helps give the 356 00:27:34,730 --> 00:27:36,630 Osprey its one -of -a -kind capabilities. 357 00:27:40,110 --> 00:27:44,610 But in order to accomplish its global missions, it needs to be transported 358 00:27:44,610 --> 00:27:48,630 distances inside the restricted space onboard an aircraft carrier. 359 00:27:48,930 --> 00:27:53,770 We have to be able to fit a high number of V -22s onto our amphibious shipping, 360 00:27:53,770 --> 00:27:57,610 so it's important that we can fold it down and fit it into tight spaces. 361 00:27:58,050 --> 00:28:02,850 To achieve this, engineers can turn to history's innovators for inspiration. 362 00:28:03,630 --> 00:28:09,050 What's amazing to me is how much still is relevant today. It's remarkable. 363 00:28:14,830 --> 00:28:17,990 To transport troops and cargo anywhere in the world. 364 00:28:18,730 --> 00:28:25,250 Engineers have created a shape -shifting military 365 00:28:25,250 --> 00:28:26,350 flying machine. 366 00:28:30,370 --> 00:28:32,910 Part helicopter and part airplane. 367 00:28:34,910 --> 00:28:38,370 The V -22 Osprey is the ultimate aircraft. 368 00:28:42,760 --> 00:28:45,500 Fitted with three fuel tanks in the fuselage. 369 00:28:47,360 --> 00:28:49,720 And two more integrated in the wings. 370 00:28:51,580 --> 00:28:55,460 The Osprey can hold close to 1 ,500 gallons of fuel. 371 00:28:56,100 --> 00:28:59,300 Around 75 times more than a family car. 372 00:29:00,340 --> 00:29:03,940 And enough to fly non -stop from Miami to Philadelphia. 373 00:29:07,900 --> 00:29:10,100 In the skies above North Carolina. 374 00:29:11,440 --> 00:29:14,060 Tail right to land on the Delta Taxiway. 375 00:29:15,820 --> 00:29:21,060 The 266 Squadron flight crew is returning to New River Air Station, 376 00:29:21,060 --> 00:29:23,100 completed a successful training flight. 377 00:29:27,140 --> 00:29:28,660 Front, three down and locked. 378 00:29:30,020 --> 00:29:31,900 Just seen, I got Blackburn on top of you. I got Blackburn. 379 00:29:32,220 --> 00:29:33,220 Copy. 380 00:29:53,360 --> 00:29:58,640 But for the Osprey to carry out its worldwide missions, the aircraft must be 381 00:29:58,640 --> 00:30:01,960 able to travel distances far beyond its flying range. 382 00:30:03,080 --> 00:30:05,980 So the Marine Corps has our nation's force in readiness. 383 00:30:06,320 --> 00:30:10,040 It's important that we have an aircraft that can operate in any place around the 384 00:30:10,040 --> 00:30:15,160 globe. So it's extremely important that the V -22 be able to fit and operate off 385 00:30:15,160 --> 00:30:17,200 of existing amphibious shipping. 386 00:30:19,820 --> 00:30:24,800 We have to be able to fit a high number of V -22s onto our amphibious shipping 387 00:30:24,800 --> 00:30:28,920 that has limited hangar space. So it's important that we can fit it into tight 388 00:30:28,920 --> 00:30:29,920 spaces. 389 00:30:32,420 --> 00:30:37,700 But squeezing an aircraft measuring 84 feet wide into a restricted footprint. 390 00:30:38,040 --> 00:30:40,520 presents a potentially impossible problem. 391 00:30:41,300 --> 00:30:45,700 The size constraints the Osprey has to fit in are approximately 20 feet wide by 392 00:30:45,700 --> 00:30:48,280 20 feet tall by about 63 feet long. 393 00:30:48,660 --> 00:30:53,580 It's a significant design challenge to combine all of the details of the Osprey 394 00:30:53,580 --> 00:30:56,960 into the small footprint while still meeting critical flight characteristics. 395 00:30:59,980 --> 00:31:04,880 To find a solution, engineers must seek inspiration from the pioneers of the 396 00:31:04,880 --> 00:31:05,880 past. 397 00:31:14,090 --> 00:31:15,250 In San Diego. 398 00:31:15,870 --> 00:31:19,250 Oh my gosh, this place is absolutely massive. 399 00:31:21,170 --> 00:31:26,830 Helicopter pilot Micah Muthio is on board an iconic aircraft carrier, the 400 00:31:26,830 --> 00:31:27,830 Midway. 401 00:31:28,870 --> 00:31:33,130 It's incredible to be standing here. This is four acres of floating aviation 402 00:31:33,130 --> 00:31:38,110 history. Can you imagine what this was like back when active? The sound of the 403 00:31:38,110 --> 00:31:40,530 jets, the spinning of the blades, all that activity. 404 00:31:43,169 --> 00:31:44,650 Commissioned in 1945, 405 00:31:45,370 --> 00:31:48,490 the Midway was once the largest ship in the world. 406 00:31:49,670 --> 00:31:54,030 As an aviation nerd, it's cool to see all the aircraft, but putting them in 407 00:31:54,030 --> 00:31:57,790 context of an actual aircraft carrier really brings it to life. 408 00:31:59,670 --> 00:32:02,550 But even the Midway's hangar space was limited. 409 00:32:03,470 --> 00:32:07,970 And aircraft with large wingspans or propeller blades are not easily 410 00:32:07,970 --> 00:32:08,970 transported. 411 00:32:10,250 --> 00:32:14,590 The Navy needed a way to maximize the number of aircraft per carrier. 412 00:32:19,610 --> 00:32:25,350 Thankfully, in 1943, engineer Michael Boyvid helped design a helicopter 413 00:32:25,350 --> 00:32:31,550 with an ingenious solution that would redefine how aircraft are transported. 414 00:32:39,880 --> 00:32:41,900 Look at this thing. It's amazing. 415 00:32:43,940 --> 00:32:48,940 This is the Sikorsky H5, also known as the Dragonfly. 416 00:32:51,640 --> 00:32:55,320 From a pilot's perspective, when I look at the cockpit, I just think the field 417 00:32:55,320 --> 00:32:58,380 of view is incredible. You can just see in all directions. 418 00:32:59,240 --> 00:33:02,540 But the view is not the H5's greatest accomplishment. 419 00:33:04,220 --> 00:33:08,550 What's amazing to me is how much... still is relevant today. 420 00:33:08,910 --> 00:33:12,950 There's so many components on here that just worked and we've stuck with them. 421 00:33:13,310 --> 00:33:18,010 And the innovative engineering behind this groundbreaking aircraft is exactly 422 00:33:18,010 --> 00:33:21,050 what the V -22 Osprey team has been looking for. 423 00:33:21,690 --> 00:33:26,530 To me, this folding mechanism is a real game changer. That's really incredible. 424 00:33:32,400 --> 00:33:36,880 The B -22 Osprey is one of the most remarkable machines on the planet. 425 00:33:40,460 --> 00:33:46,260 Built to carry troops and cargo at high speed over long distances and into hard 426 00:33:46,260 --> 00:33:52,800 -to -reach locations, it can achieve the seemingly impossible by 427 00:33:52,800 --> 00:33:56,300 transforming itself from helicopter to airplane in midair. 428 00:33:57,780 --> 00:34:01,300 But each individual aircraft has a huge footprint. 429 00:34:01,580 --> 00:34:03,900 making them difficult to transport and store. 430 00:34:04,540 --> 00:34:09,880 To solve this problem and maximize the Osprey's potential, engineers are 431 00:34:09,880 --> 00:34:15,199 to the Sikorsky H -5, a pioneering helicopter that inspired the team behind 432 00:34:15,199 --> 00:34:16,199 Osprey. 433 00:34:17,060 --> 00:34:23,280 So the H -5 was special because it was very high performance, flew up to 21 434 00:34:23,280 --> 00:34:25,960 feet, which is something I've never done in a helicopter. 435 00:34:26,739 --> 00:34:29,219 What's amazing to me is how much... 436 00:34:29,520 --> 00:34:31,120 still is relevant today. 437 00:34:31,500 --> 00:34:35,300 There are so many components on here that just worked, and we've stuck with 438 00:34:35,300 --> 00:34:36,300 them. It's remarkable. 439 00:34:38,139 --> 00:34:44,760 Built to offer the armed forces a helicopter that could carry greater 440 00:34:44,760 --> 00:34:51,280 fly longer, faster, and higher than previously possible, the H -5's 441 00:34:51,280 --> 00:34:55,179 performance allowed it to become the first helicopter to operate in the 442 00:34:55,179 --> 00:34:56,179 Antarctic. 443 00:34:57,960 --> 00:35:02,520 But arguably the most important of this exceptional aircraft's features was its 444 00:35:02,520 --> 00:35:04,080 revolutionary rotor blades. 445 00:35:06,040 --> 00:35:10,360 Look at these blades. They take up so much space. It's like a big ring all the 446 00:35:10,360 --> 00:35:11,380 way around the helicopter. 447 00:35:11,940 --> 00:35:16,400 That's really inefficient use of space, especially if you have the confines of 448 00:35:16,400 --> 00:35:17,400 an aircraft carrier. 449 00:35:17,960 --> 00:35:20,860 We're in a hangar right here. There's not a lot of space. 450 00:35:21,310 --> 00:35:22,370 the rotor system. 451 00:35:22,570 --> 00:35:26,170 It's roughly 50 feet in diameter, and if you get two of these side by side, 452 00:35:26,270 --> 00:35:29,750 that's 100 feet of space that you're taking up just because of the rotor 453 00:35:33,870 --> 00:35:38,310 But as Micah is about to discover with help from the carrier's crew, these 454 00:35:38,310 --> 00:35:41,590 blades can perform an innovative feature to solve the problem. 455 00:35:41,930 --> 00:35:45,590 So the first thing you're taking out, that's the pitch link bolt. The pitch 456 00:35:45,590 --> 00:35:47,550 link. It controls the pitch of the blade. 457 00:35:47,870 --> 00:35:51,450 Okay. Now what I'm going to do, I'm going to rotate it. So basically I'm 458 00:35:51,450 --> 00:35:52,730 to change the pitch on the blade. 459 00:35:52,970 --> 00:35:54,510 Okay. We're going down. 460 00:35:55,150 --> 00:35:59,930 Going down. Now he's going to pull the wing or the blade attach bolt out so 461 00:35:59,930 --> 00:36:03,850 we can swing the blade. Gotcha. And that lets the whole blade rotate back. Yes. 462 00:36:04,050 --> 00:36:05,050 Okay. 463 00:36:05,090 --> 00:36:07,550 Here's the moment where I hope not to drop it. Okay. 464 00:36:08,090 --> 00:36:09,950 Oh, and it just rotates back like that. Okay. 465 00:36:11,009 --> 00:36:12,210 I think it's pretty easy. 466 00:36:12,830 --> 00:36:14,190 Okay, just walking it back. 467 00:36:14,610 --> 00:36:15,610 Okay. 468 00:36:16,450 --> 00:36:21,550 After removing just two bolts, the blades are ready to fold, allowing the 469 00:36:21,550 --> 00:36:24,110 be totally transformed in a little over a minute. 470 00:36:26,170 --> 00:36:27,550 Okay, coming down a little bit. 471 00:36:27,790 --> 00:36:31,750 So we're going to drop the blade down. Slide it up into the cradle. Slide it 472 00:36:34,390 --> 00:36:37,790 And then two bolts back here for the little clamp, and good to go. 473 00:36:39,029 --> 00:36:42,910 When they started bringing the H -5 onto ships, they would just fold them back 474 00:36:42,910 --> 00:36:45,470 like this, and this is how you store them. 475 00:36:45,670 --> 00:36:49,170 Yeah, except for back then you had two 20 -year -old sailors doing it. 476 00:36:49,730 --> 00:36:51,490 A couple of old guys like that. 477 00:36:53,690 --> 00:36:59,450 And after repeating the same process on the opposite side of the aircraft, the H 478 00:36:59,450 --> 00:37:03,370 -5 can complete a feat that had previously been impossible for a 479 00:37:04,189 --> 00:37:08,750 By fully folding its blade, the H5 significantly shrinks its footprint. 480 00:37:09,330 --> 00:37:11,710 All right, now what I'm going to do is I'm going to rotate it a little farther 481 00:37:11,710 --> 00:37:12,810 to where I can drop it out. 482 00:37:13,110 --> 00:37:14,710 And coming down a little bit. Okay. 483 00:37:15,710 --> 00:37:17,850 I'm not going to say there's a lot of pressure here, but this is a very old 484 00:37:17,850 --> 00:37:20,590 helicopter, and the guy holding the blade, don't want to break it. 485 00:37:24,190 --> 00:37:25,190 Got that. 486 00:37:27,560 --> 00:37:30,900 It is remarkable, though, that just a few seconds ago this thing was ready to 487 00:37:30,900 --> 00:37:32,220 fly. Yes. Well, ish. 488 00:37:33,220 --> 00:37:34,720 And now here we are. 489 00:37:35,300 --> 00:37:36,300 Okay. 490 00:37:36,720 --> 00:37:38,860 That was suspiciously easy. 491 00:37:39,500 --> 00:37:41,420 I think I'm ready to join the crew, guys. 492 00:37:42,040 --> 00:37:43,660 I'm ready to join your squad. 493 00:37:46,820 --> 00:37:51,820 Voyvich's transformative blade fold design helped revolutionize the 494 00:37:51,820 --> 00:37:56,560 military aircraft, dramatically reducing the space required to carry a 495 00:37:56,560 --> 00:38:01,180 helicopter. What's incredible to me is that we've gone from 50 feet wide to 5 496 00:38:01,180 --> 00:38:03,280 feet wide in about a minute. 497 00:38:03,860 --> 00:38:08,620 And today, blade folding is still an essential feature on an array of modern 498 00:38:08,620 --> 00:38:13,160 aircraft, proving the importance of Boyvitt's ingenious invention. 499 00:38:14,260 --> 00:38:19,600 To me, this folding mechanism is a real game -changer, making it possible to fly 500 00:38:19,600 --> 00:38:23,180 a helicopter from a ship -borne environment. That's really incredible. 501 00:38:24,490 --> 00:38:29,350 To complete the V -22 Osprey and make one of the most versatile aircraft in 502 00:38:29,350 --> 00:38:33,310 history, engineers will take Boivitt's brilliant solution. 503 00:38:33,550 --> 00:38:37,090 It's amazing to see such a massive aircraft turn into such a small 504 00:38:37,090 --> 00:38:39,410 like this. And make it all their own. 505 00:38:39,670 --> 00:38:42,670 This is the world's first complete blade -folded wing -sew system. 506 00:38:47,210 --> 00:38:51,810 Today in North Carolina, the V -22 Osprey's engineers have taken Michael 507 00:38:51,810 --> 00:38:53,430 Boivitt's blade -fold innovation. 508 00:38:53,720 --> 00:38:56,800 and modernized it to achieve a new feat in aviation. 509 00:39:00,240 --> 00:39:03,320 This is the world's first complete blade fold and wing sew system. 510 00:39:06,520 --> 00:39:10,840 There are other platforms that use a portion of blade fold or a portion of 511 00:39:10,840 --> 00:39:14,740 sew, but in no cases is there a complete process all in one aircraft. 512 00:39:17,120 --> 00:39:20,280 Unlike the manual fold method designed for the H -5, 513 00:39:21,690 --> 00:39:25,230 The Osprey's unique system is entirely automated. 514 00:39:27,790 --> 00:39:31,310 At the start of the blade fold sequence, the squash plate actuators that control 515 00:39:31,310 --> 00:39:34,470 the rotor head move to the fully retracted position. 516 00:39:34,750 --> 00:39:36,390 This causes the blades to hit vertical. 517 00:39:37,690 --> 00:39:42,430 The aircraft then folds the outer two blades so that they join the blade 518 00:39:42,430 --> 00:39:43,430 currently over the wing. 519 00:39:43,730 --> 00:39:47,390 Once that's complete, the cells begin to rotate down into the horizontal 520 00:39:47,390 --> 00:39:50,070 position, and in doing so, the wing also begins to rotate. 521 00:39:52,040 --> 00:39:56,980 Once the wing has completed its rotation to sit parallel with the airframe, the 522 00:39:56,980 --> 00:40:02,380 operation is complete, taking approximately 90 seconds to shrink the 523 00:40:02,380 --> 00:40:06,200 84 feet wide to less than 19 feet wide. 524 00:40:07,300 --> 00:40:10,660 The execution of the blade full wings is like a party trick. 525 00:40:10,980 --> 00:40:14,160 It's amazing to see such a massive aircraft turn into such a small 526 00:40:14,160 --> 00:40:15,160 like this. 527 00:40:15,700 --> 00:40:19,800 It's a remarkable transformation that's vital to the Osprey's functionality. 528 00:40:20,480 --> 00:40:24,380 allowing the aircraft to operate from the confines of an aircraft carrier. 529 00:40:25,820 --> 00:40:26,400 This 530 00:40:26,400 --> 00:40:34,720 feature, 531 00:40:34,860 --> 00:40:39,980 along with the V -22 Osprey's other unique capabilities, make this 532 00:40:39,980 --> 00:40:44,420 aircraft one of the most advanced machines ever to navigate the sky. 533 00:40:46,600 --> 00:40:49,460 Every day I look at the Osprey, I can't believe how amazing it looks. 534 00:40:49,930 --> 00:40:53,390 The engineering that was involved to design this aircraft blows me away. 535 00:40:54,290 --> 00:40:57,950 It's an extreme honor and privilege for me to be part of this Osprey team, not 536 00:40:57,950 --> 00:41:01,490 just for this fantastic aircraft, but also to work with those men and women 537 00:41:01,490 --> 00:41:02,490 keep this aircraft flying. 538 00:41:07,270 --> 00:41:10,570 By looking to the pioneers of the past for inspiration. 539 00:41:12,750 --> 00:41:14,030 Adapting their ideas. 540 00:41:15,050 --> 00:41:16,690 Building on their designs. 541 00:41:17,420 --> 00:41:20,160 and triumphing over enormous challenges. 542 00:41:21,700 --> 00:41:26,540 This is a game -changing aircraft for the Marines. It accomplishes things that 543 00:41:26,540 --> 00:41:27,980 no other aircraft can accomplish. 544 00:41:28,280 --> 00:41:30,500 It's a real -life transforming. 545 00:41:32,880 --> 00:41:38,200 The Ospreys team has created a revolutionary piece of aviation 546 00:41:38,200 --> 00:41:44,340 and succeeded in making the impossible possible. 547 00:41:45,840 --> 00:41:49,820 It wasn't long ago that people thought it impossible to combine both helicopter 548 00:41:49,820 --> 00:41:51,600 and airplane capabilities. 549 00:41:51,880 --> 00:41:54,080 We've redefined what's possible on the battlefield. 550 00:41:54,130 --> 00:41:58,680 Repair and Synchronization by Easy Subtitles Synchronizer 1.0.0.0 52563
