Captions paid for by
Discovery communications
3
00:00:53,758 --> 00:00:55,206
Narrator: the word champagne
4
00:00:55,206 --> 00:00:59,241
Is often used to describe
Sparkling white wines.
5
00:00:59,241 --> 00:01:02,379
But true champagne can only come
From the champagne region
6
00:01:02,379 --> 00:01:04,413
Of france.
7
00:01:04,413 --> 00:01:06,896
It must meet a long list
Of special requirements
8
00:01:06,896 --> 00:01:09,000
Before receiving
The coveted label.
9
00:01:14,310 --> 00:01:17,482
The champagne industry
Is heavily regulated.
10
00:01:17,482 --> 00:01:20,448
The grapes must be locally grown
In the champagne region
11
00:01:20,448 --> 00:01:22,413
Of france.
12
00:01:22,413 --> 00:01:26,344
They can only use three types
Of grapes, black pinot noir,
13
00:01:26,344 --> 00:01:27,551
Pinot meunier,
14
00:01:27,551 --> 00:01:32,034
Or white chardonnay,
To produce champagne.
15
00:01:32,034 --> 00:01:34,068
Additional rules regulate
How the grapes
16
00:01:34,068 --> 00:01:39,344
Can be pruned, picked,
Pressed, fermented and aged.
17
00:01:39,344 --> 00:01:42,206
Workers harvest the grapes
In mid-september.
18
00:01:42,206 --> 00:01:45,034
They use aerated crates
To transfer the crops
19
00:01:45,034 --> 00:01:46,655
To a grape press.
20
00:01:46,655 --> 00:01:47,827
They crush the grapes
21
00:01:47,827 --> 00:01:50,000
And immediately filter
The juice.
22
00:01:50,000 --> 00:01:53,413
The grape skins and pulp
Can alter the juice's flavor,
23
00:01:53,413 --> 00:01:57,517
So they have to be removed
Quickly.
24
00:01:57,517 --> 00:02:03,137
Vintage champagne is fermented
In old oak barrels.
25
00:02:03,137 --> 00:02:05,655
They use a sulfur disk
To disinfect the barrels
26
00:02:05,655 --> 00:02:07,586
Between uses.
27
00:02:07,586 --> 00:02:10,241
First, a worker
Lights the disk and inserts
28
00:02:10,241 --> 00:02:12,000
It through a hole on the side.
29
00:02:12,000 --> 00:02:15,034
The flame goes out once
It's sealed inside the barrel.
30
00:02:15,034 --> 00:02:16,862
The sulfur smoke
Fills the barrel
31
00:02:16,862 --> 00:02:19,275
And kills off any bacteria.
32
00:02:19,275 --> 00:02:20,793
Non-vintage champagnes
33
00:02:20,793 --> 00:02:23,517
Are produced
In these stainless steel tanks.
34
00:02:23,517 --> 00:02:26,551
They start the fermentation
Process by adding yeast
35
00:02:26,551 --> 00:02:28,482
To the grape juice.
36
00:02:28,482 --> 00:02:30,413
In about 10 days, the yeast
37
00:02:30,413 --> 00:02:36,034
Turns the sugar into alcohol
And carbon dioxide gas.
38
00:02:36,034 --> 00:02:40,206
The alcohol level of the wine
Is now about 10 1/2 percent.
39
00:02:40,206 --> 00:02:41,586
There are no bubbles yet
40
00:02:41,586 --> 00:02:46,931
Because the co2 escaped
Through the top of the tank.
41
00:02:46,931 --> 00:02:49,379
Each fermentation barrel
And tank
42
00:02:49,379 --> 00:02:53,068
Is labeled based on where
The juice inside originated.
43
00:02:53,068 --> 00:02:56,413
The grape juices from each
Village have distinctive tastes,
44
00:02:56,413 --> 00:03:01,931
Caused by differences in soil
Composition and sun exposure.
45
00:03:01,931 --> 00:03:05,448
Blending begins
After the first fermentation.
46
00:03:05,448 --> 00:03:09,034
The winery's experts experiment
With different combinations
47
00:03:09,034 --> 00:03:13,206
Until they find the taste
And aroma they're looking for.
48
00:03:13,206 --> 00:03:16,068
They bottle the mixture
With yeast and sugar,
49
00:03:16,068 --> 00:03:19,620
And place it in a cold,
Damp cellar for 5 weeks.
50
00:03:19,620 --> 00:03:22,586
This second fermentation
Raises the alcohol content
51
00:03:22,586 --> 00:03:25,965
To 12 1/2 percent.
52
00:03:25,965 --> 00:03:27,344
After fermentation,
53
00:03:27,344 --> 00:03:29,620
They lie the bottles
Down horizontally
54
00:03:29,620 --> 00:03:34,517
And let the champagne age
For up to 10 years.
55
00:03:34,517 --> 00:03:35,896
After the aging,
56
00:03:35,896 --> 00:03:39,068
The bottles go into a machine
That freezes the neck.
57
00:03:39,068 --> 00:03:44,275
The yeast residue freezes in
A small ice cube under the cork.
58
00:03:44,275 --> 00:03:49,000
The carbon dioxide is invented
During the second fermentation.
59
00:03:49,000 --> 00:03:50,758
When workers open each bottle,
60
00:03:50,758 --> 00:03:53,758
The gas pressure
Ejects the ice cube.
61
00:03:53,758 --> 00:03:56,931
This procedure is called
Disgorging.
62
00:03:56,931 --> 00:03:58,448
A worker turns the bottle
63
00:03:58,448 --> 00:04:01,620
To minimize the amount
Of champagne that escapes.
64
00:04:01,620 --> 00:04:06,655
Then he smells it to make sure
The champagne hasn't spoiled.
65
00:04:06,655 --> 00:04:08,413
The winery
66
00:04:08,413 --> 00:04:11,655
Makes a special liqueur
Out of wine and cane sugar,
67
00:04:11,655 --> 00:04:14,068
Which they add to the champagne.
68
00:04:14,068 --> 00:04:17,034
The amount of liqueur added
Brings the champagne to one
69
00:04:17,034 --> 00:04:18,689
Of three sweetness levels,
70
00:04:18,689 --> 00:04:20,413
Known as brut, sec,
71
00:04:20,413 --> 00:04:22,137
Or demi-sec.
72
00:04:22,137 --> 00:04:26,379
The filling machine secures
The new cork with a wire cap.
73
00:04:26,379 --> 00:04:30,379
The next machine rotate the
Bottles to mix in the liqueur.
74
00:04:30,379 --> 00:04:32,206
Then the bottles
Go into the cellar
75
00:04:32,206 --> 00:04:34,689
For at least 3 months.
76
00:04:34,689 --> 00:04:36,310
After they come
Out of the cellar,
77
00:04:36,310 --> 00:04:40,655
The bottles go through
An automated washing machine.
78
00:04:40,655 --> 00:04:43,896
A worker inspects every bottle
For floating cork particles
79
00:04:43,896 --> 00:04:47,448
Or flaws in the glass.
80
00:04:47,448 --> 00:04:49,689
The labeling machine's
First station places
81
00:04:49,689 --> 00:04:51,862
Gold foil over the neck.
82
00:04:51,862 --> 00:04:55,206
The foil label
Bears the winery's name.
83
00:04:55,206 --> 00:04:58,068
The second station fires a shot
Of compressed air
84
00:04:58,068 --> 00:05:00,482
To mold the foil
To the shape of the cork.
85
00:05:06,103 --> 00:05:08,413
The third station glues
On the neck label.
86
00:05:08,413 --> 00:05:13,172
It's made of varnished paper.
87
00:05:13,172 --> 00:05:14,551
Then, the last station
88
00:05:14,551 --> 00:05:19,103
Applies an adhesive label
To the front of the bottle.
89
00:05:19,103 --> 00:05:20,724
A scanner makes sure the foil
90
00:05:20,724 --> 00:05:23,241
And labels
Are in the correct place.
91
00:05:28,206 --> 00:05:33,172
This bottle of champagne
Is finally ready to drink.
92
00:05:33,172 --> 00:05:38,275
When you pop the cork, the gas
Trapped inside gently escapes.
93
00:05:38,275 --> 00:05:40,241
Shaking the bottle
Just before opening
94
00:05:40,241 --> 00:05:44,689
Will cause an even more dramatic
Champagne explosion.
95
00:05:44,689 --> 00:05:48,758
Either way, it's the perfect
Drink to celebrate any occasion.
96
00:05:48,758 --> 00:05:50,758
Cheers.
97
00:06:02,448 --> 00:06:04,620
Narrator: before the automated
Teller machine,
98
00:06:04,620 --> 00:06:07,482
Withdrawals and deposits
Were made in person.
99
00:06:07,482 --> 00:06:09,275
Then, in the 1960s,
100
00:06:09,275 --> 00:06:12,896
Simple cash machines started
To appear all over europe.
101
00:06:12,896 --> 00:06:16,000
Later, more sophisticated
Versions were developed.
102
00:06:16,000 --> 00:06:18,517
Today's atms
Make it easy and convenient
103
00:06:18,517 --> 00:06:22,793
To bank outside
Of normal business hours.
104
00:06:22,793 --> 00:06:25,310
Atms are made of two sections.
105
00:06:25,310 --> 00:06:29,103
The bottom is a steel safe
That houses the cash dispenser.
106
00:06:29,103 --> 00:06:33,517
The head module contains
All the user features on top.
107
00:06:33,517 --> 00:06:38,793
Most of the atm's non-electronic
Parts are cut from steel sheets.
108
00:06:38,793 --> 00:06:40,310
Workers load the steel sheets
109
00:06:40,310 --> 00:06:42,724
Into a computer-guided
Laser cutting machine.
110
00:06:42,724 --> 00:06:46,965
The laser uses focused light
To generate intense heat.
111
00:06:46,965 --> 00:06:49,827
The heat melts the steel
To make the cuts.
112
00:06:53,344 --> 00:06:56,448
The simpler parts are stamped
With a die and a press.
113
00:07:01,413 --> 00:07:03,034
Next, a robot loads
114
00:07:03,034 --> 00:07:06,758
The piece into a fully-automated
Computer-guided bending press.
115
00:07:06,758 --> 00:07:09,758
The press bends the part
Into the required shape.
116
00:07:21,034 --> 00:07:22,862
A computer guided spot welder
117
00:07:22,862 --> 00:07:26,482
Fuses the simple parts
Together at set intervals.
118
00:07:26,482 --> 00:07:28,137
For more complex parts,
119
00:07:28,137 --> 00:07:32,172
A computer guided 3-d laser
Welds the entire joint.
120
00:07:37,206 --> 00:07:38,965
An automated transport system
121
00:07:38,965 --> 00:07:41,137
Dips the steel parts
In a metal primer
122
00:07:41,137 --> 00:07:44,103
To prevent corrosion.
123
00:07:44,103 --> 00:07:48,655
After dipping,
They dry the parts in an oven.
124
00:07:48,655 --> 00:07:51,896
The housing parts are sprayed
With liquid or powder paint.
125
00:07:54,758 --> 00:07:58,413
Then they go into an oven
To bake on the color.
126
00:07:58,413 --> 00:08:02,758
This is the internal structure
For the atm's head module.
127
00:08:02,758 --> 00:08:05,965
Workers assemble all the
Module's internal components,
128
00:08:05,965 --> 00:08:10,137
Including the power unit
And the atm's computer.
129
00:08:10,137 --> 00:08:13,758
Then, they lower the head module
Onto the atm's steel safe.
130
00:08:16,413 --> 00:08:19,068
The safe's walls
Can be up to 2 inches thick.
131
00:08:21,965 --> 00:08:25,379
There's a separate assembly line
For the operation panel.
132
00:08:25,379 --> 00:08:28,275
This panel goes on the front
Of the head module.
133
00:08:28,275 --> 00:08:31,758
It contains everything used
In an atm transaction,
134
00:08:31,758 --> 00:08:33,793
From the card reader,
To the key pad,
135
00:08:33,793 --> 00:08:35,586
And even the speaker system.
136
00:08:39,379 --> 00:08:42,793
The key pad encrypts the user's
Personal identification number
137
00:08:42,793 --> 00:08:47,551
Inside the atm.
138
00:08:47,551 --> 00:08:50,620
The machine has up
To three security cameras.
139
00:08:50,620 --> 00:08:55,758
They record the key pad,
The cash tray and the atm user.
140
00:08:55,758 --> 00:08:59,344
Workers connect the monitor
To the internal computer.
141
00:08:59,344 --> 00:09:03,758
They also install the card
Reader and the receipt slot.
142
00:09:03,758 --> 00:09:05,344
At the bank's request,
143
00:09:05,344 --> 00:09:08,517
They can install
A separate module for deposits.
144
00:09:08,517 --> 00:09:12,551
However, this atm uses the cash
Out slot to accept deposits.
145
00:09:16,862 --> 00:09:19,275
Workers also install
The shutter,
146
00:09:19,275 --> 00:09:22,413
A computer-controlled flap
On the cash out slot.
147
00:09:22,413 --> 00:09:24,620
It opens when the machine
Accepts a deposit
148
00:09:24,620 --> 00:09:28,793
Or dispenses money.
149
00:09:28,793 --> 00:09:31,413
Next, workers
Mount the operation panel
150
00:09:31,413 --> 00:09:34,448
To the head module.
151
00:09:34,448 --> 00:09:35,931
On a separate assembly line,
152
00:09:35,931 --> 00:09:39,379
They prepare the electronic
Mechanical unit.
153
00:09:39,379 --> 00:09:40,827
It dispenses the money
154
00:09:40,827 --> 00:09:43,379
And accepts cash
And checks for deposits.
155
00:09:47,965 --> 00:09:52,172
Workers load cassettes into the
Unit for each cash denomination.
156
00:09:52,172 --> 00:09:57,034
The bank will separate and stock
The cash for their atm.
157
00:09:57,034 --> 00:09:59,379
Before they install the unit
In the atm,
158
00:09:59,379 --> 00:10:01,551
They hook it up
To a test computer.
159
00:10:01,551 --> 00:10:04,931
They test a few different
Transactions with fake bills
160
00:10:04,931 --> 00:10:07,310
To make sure
It dispenses the correct amount.
161
00:10:10,931 --> 00:10:12,896
If the unit passes testing,
162
00:10:12,896 --> 00:10:15,482
Workers
Install it in the atm safe.
163
00:10:20,000 --> 00:10:22,000
They run a couple
Of the finished machines
164
00:10:22,000 --> 00:10:27,379
Through several
Quality control tests.
165
00:10:27,379 --> 00:10:29,379
First, a shake test
166
00:10:29,379 --> 00:10:34,172
Ensures the atm can withstand
A bumpy ride during transport.
167
00:10:34,172 --> 00:10:36,310
Next, they conduct a shower test
168
00:10:36,310 --> 00:10:40,310
To ensure that rain
Won't damage an outdoor atm.
169
00:10:40,310 --> 00:10:42,310
There's also a climate test.
170
00:10:42,310 --> 00:10:45,793
They place the atm in a chamber
That simulates temperature
171
00:10:45,793 --> 00:10:50,793
Ranging from negative 40 degrees
To over 120 degrees fahrenheit.
172
00:10:50,793 --> 00:10:53,379
Atms designed
For extreme temperatures
173
00:10:53,379 --> 00:10:57,172
Usually have built-in heating
Or cooling systems.
174
00:10:57,172 --> 00:11:01,551
Every atm comes with basic
Operating software installed.
175
00:11:01,551 --> 00:11:04,413
The banks then
Install their custom software
176
00:11:04,413 --> 00:11:08,034
Or have the manufacturer
Do it for them.
177
00:11:17,379 --> 00:11:20,172
It takes a powerful engine
To move a cruise liner
178
00:11:20,172 --> 00:11:22,379
Or a cargo vessel.
179
00:11:22,379 --> 00:11:25,034
Turbochargers help
Make it possible.
180
00:11:25,034 --> 00:11:27,068
They double the diesel
Engine's output
181
00:11:27,068 --> 00:11:30,896
To 100,000 horsepower or more.
182
00:11:30,896 --> 00:11:34,586
Turbochargers also use exhaust
Gases to run the compressor.
183
00:11:38,448 --> 00:11:39,758
In a ship's engine,
184
00:11:39,758 --> 00:11:43,137
The turbocharger is
A welcome breath of fresh air.
185
00:11:43,137 --> 00:11:45,413
It's capable
Of significantly boosting
186
00:11:45,413 --> 00:11:47,034
The engine's performance.
187
00:11:47,034 --> 00:11:49,620
It does this by compressing
Almost 200 feet
188
00:11:49,620 --> 00:11:51,172
Of air per second,
189
00:11:51,172 --> 00:11:54,758
Then thrusting that air into
The engine's combustion chamber.
190
00:11:54,758 --> 00:11:57,206
First,
They make the turbine wheel.
191
00:11:57,206 --> 00:12:00,689
It's used
To extract the exhaust gases.
192
00:12:00,689 --> 00:12:03,172
A long cutting tool
Known as a broach
193
00:12:03,172 --> 00:12:07,068
Carves a tree-shaped pattern
Around the edge of a steel disk.
194
00:12:07,068 --> 00:12:08,448
The pine tree shapes
195
00:12:08,448 --> 00:12:11,000
Are designed to interlock
With the matching blades.
196
00:12:15,448 --> 00:12:18,827
Next, a computer-guided saw
Slices a brass alloy
197
00:12:18,827 --> 00:12:21,482
Cylinder into small bearings.
198
00:12:21,482 --> 00:12:24,172
These bearings will support
The turbine shaft.
199
00:12:28,275 --> 00:12:30,172
They make several bearings
In a range
200
00:12:30,172 --> 00:12:33,137
Of sizes and materials
For different turbochargers.
201
00:12:36,413 --> 00:12:40,379
Computerized tools mill the
Surface of the axial bearing.
202
00:12:40,379 --> 00:12:43,068
They also drill holes
To connect the turbine rotor
203
00:12:43,068 --> 00:12:45,482
And the casing.
204
00:12:45,482 --> 00:12:49,068
This is the completed bearing.
205
00:12:49,068 --> 00:12:50,379
A worker inserts one
206
00:12:50,379 --> 00:12:54,034
Of the turbochargers
Nickel alloy blades in a mold.
207
00:12:54,034 --> 00:12:57,448
He leaves the foot
Of the blade sticking out.
208
00:12:57,448 --> 00:13:00,000
He slides the mold
Directly under a spout,
209
00:13:00,000 --> 00:13:03,137
Which dispenses a hot
Liquefied tin alloy.
210
00:13:05,275 --> 00:13:09,655
He fills the mold to the top.
211
00:13:09,655 --> 00:13:12,620
The tin alloy solidifies,
Encasing the blade
212
00:13:12,620 --> 00:13:15,206
Just below the foot.
213
00:13:15,206 --> 00:13:17,586
This structure will fit
Into a clamping device
214
00:13:17,586 --> 00:13:21,586
In the grinding operation.
215
00:13:21,586 --> 00:13:24,275
An employee
Inserts the tin-encased blades
216
00:13:24,275 --> 00:13:29,896
Into tensioning devices
In the grinding machine.
217
00:13:29,896 --> 00:13:31,689
Inside the tensioning device,
218
00:13:31,689 --> 00:13:35,793
A clamping mechanism
Grips the blades.
219
00:13:35,793 --> 00:13:37,448
As coolant flows,
220
00:13:37,448 --> 00:13:41,965
A computerized grinder
Carves grooves in the feet.
221
00:13:41,965 --> 00:13:44,931
They're specially designed
To engage with the tree pattern
222
00:13:44,931 --> 00:13:47,448
On the turbine disk.
223
00:13:47,448 --> 00:13:50,275
They pull the tin alloy blocks
Out of the machine.
224
00:13:52,655 --> 00:13:54,172
They break the tin alloy,
225
00:13:54,172 --> 00:13:58,517
And remove the blade inside.
226
00:13:58,517 --> 00:14:01,206
Now, it's ready to be connected
To the turbine wheel.
227
00:14:03,586 --> 00:14:08,206
A worker slides the blade foot
Into place on the turbine disk.
228
00:14:08,206 --> 00:14:11,000
Then he bends a clip
Back halfway, with pliers.
229
00:14:13,551 --> 00:14:15,689
He tightens the alignment
With a clamp.
230
00:14:21,551 --> 00:14:23,586
He hammers the clamp
Down further,
231
00:14:23,586 --> 00:14:25,793
Until it lays flat
Against the blade foot
232
00:14:25,793 --> 00:14:28,517
And turbine wheel.
233
00:14:28,517 --> 00:14:30,620
This secures the blade
To the wheel.
234
00:14:33,517 --> 00:14:35,931
He continues until the blades
Are in place.
235
00:14:40,551 --> 00:14:43,344
It takes 41 blades
To complete the job.
236
00:14:46,448 --> 00:14:50,068
Next, computerized tools mill
The aluminum compressor wheel
237
00:14:50,068 --> 00:14:54,413
And prepare it for cutting.
238
00:14:54,413 --> 00:14:57,758
The tools carve blades
And grooves in the compressor.
239
00:14:57,758 --> 00:15:00,758
The design makes the compressor
More aerodynamic.
240
00:15:05,000 --> 00:15:07,206
An aerodynamic compressor
Is important
241
00:15:07,206 --> 00:15:09,931
Because it allows more air
To reach the ship's engine.
242
00:15:15,827 --> 00:15:17,448
Here's the compressor wheel
243
00:15:17,448 --> 00:15:19,758
Before and after
The milling operation.
244
00:15:22,689 --> 00:15:24,310
Next,
They run through compressor
245
00:15:24,310 --> 00:15:26,068
Through a safety test.
246
00:15:26,068 --> 00:15:27,827
They lower it into a chamber
247
00:15:27,827 --> 00:15:30,655
And spin it a lot faster than
It would normally operate.
248
00:15:33,310 --> 00:15:35,931
They confirm that the compressor
Can withstand a speed
249
00:15:35,931 --> 00:15:39,517
Of 27,000 revolutions
Per minute without breaking.
250
00:15:44,517 --> 00:15:48,827
Next, the compressor wheel
Receives an ultrasonic cleaning.
251
00:15:48,827 --> 00:15:51,620
High frequency sound waves
Ripple through the water
252
00:15:51,620 --> 00:15:53,068
To scrub off any grease
253
00:15:53,068 --> 00:15:56,448
And contaminants.
254
00:15:56,448 --> 00:15:59,896
A worker uses a blower to start
Drying the compressor wheel.
255
00:16:04,551 --> 00:16:07,344
Then, he lowers it into a dryer
To get rid
256
00:16:07,344 --> 00:16:10,965
Of any residual moisture.
257
00:16:10,965 --> 00:16:12,137
When we return,
258
00:16:12,137 --> 00:16:15,137
This marine turbocharger
Will become seaworthy.
259
00:16:15,137 --> 00:16:17,206
Stay tuned.
260
00:16:32,344 --> 00:16:34,413
Narrator: turbochargers
Deliver fresh air
261
00:16:34,413 --> 00:16:36,275
To big ship engines.
262
00:16:36,275 --> 00:16:38,034
This enhances their combustion
263
00:16:38,034 --> 00:16:40,655
And adds
To their mechanical might.
264
00:16:40,655 --> 00:16:42,241
Turbochargers help
265
00:16:42,241 --> 00:16:45,448
Make these diesel engines among
The most powerful in the world,
266
00:16:45,448 --> 00:16:47,862
Allowing them to move
Gigantic vessels
267
00:16:47,862 --> 00:16:49,586
Swiftly through the water.
268
00:16:53,103 --> 00:16:55,586
A technician
Shines an ultraviolet light
269
00:16:55,586 --> 00:16:58,137
Onto the surface
Of the compressor wheel.
270
00:16:58,137 --> 00:17:00,068
This illuminates any fine cracks
271
00:17:00,068 --> 00:17:03,103
That could compromise
Its quality.
272
00:17:03,103 --> 00:17:07,862
If no cracks are found,
They start assembling the rotor.
273
00:17:07,862 --> 00:17:12,068
The employee slides bearings
Onto the main shaft and turbine.
274
00:17:12,068 --> 00:17:13,310
He uses a crane
275
00:17:13,310 --> 00:17:15,551
To align the center hole
Of the compressor wheel
276
00:17:15,551 --> 00:17:19,965
With the shaft.
277
00:17:19,965 --> 00:17:22,793
He guides it into place
And fits it to the bearing.
278
00:17:28,034 --> 00:17:32,103
Then he screws a cone-shaped cap
Onto the end.
279
00:17:32,103 --> 00:17:35,275
The turbine wheel is connected
To one end of the shaft,
280
00:17:35,275 --> 00:17:38,034
And the compressor
Is connected to the other.
281
00:17:38,034 --> 00:17:43,137
The core parts of this
Turbocharger are now assembled.
282
00:17:43,137 --> 00:17:45,862
A technician locks the rotor
In a balancing machine.
283
00:17:49,137 --> 00:17:52,379
When he activates the machine,
The rotor starts spinning.
284
00:17:55,068 --> 00:17:56,896
Sensors detect the speed
285
00:17:56,896 --> 00:17:59,517
And the angular position
Of the rotor.
286
00:17:59,517 --> 00:18:03,551
They also check
For any possible imbalances.
287
00:18:03,551 --> 00:18:06,517
The team uses this information
To shave down the rotor
288
00:18:06,517 --> 00:18:07,896
And bring it into balance.
289
00:18:12,172 --> 00:18:16,862
Then, the final assembly
Of the turbocharger begins.
290
00:18:16,862 --> 00:18:19,862
The team screws the iron casing
To the gas outlet.
291
00:18:22,482 --> 00:18:24,551
They attach three bearings
To it.
292
00:18:32,103 --> 00:18:35,137
This insert is called
The labyrinth cover.
293
00:18:35,137 --> 00:18:38,896
It will act as a seal
For the turbine disk and shaft.
294
00:18:38,896 --> 00:18:41,896
The long bolts fit into holes
In the bearing casing.
295
00:18:45,344 --> 00:18:48,000
He moves to the other side,
296
00:18:48,000 --> 00:18:50,551
And secures the protruding bolts
And nuts.
297
00:18:55,241 --> 00:18:58,827
He removes the compressor wheel
Temporarily to slide the shaft
298
00:18:58,827 --> 00:19:00,655
Through the center bearing.
299
00:19:00,655 --> 00:19:05,586
The turbine wheel fits perfectly
Over the labyrinth cover.
300
00:19:05,586 --> 00:19:06,862
On the other side,
301
00:19:06,862 --> 00:19:11,310
He bolts the labyrinth disk
To the casing.
302
00:19:11,310 --> 00:19:14,862
The labyrinth disk protects
Against hot turbine exhaust gas
303
00:19:14,862 --> 00:19:16,793
And prevents oil leakage.
304
00:19:21,413 --> 00:19:23,965
Then, he re-installs
The compressor wheel.
305
00:19:33,206 --> 00:19:34,896
Meanwhile, an employee
306
00:19:34,896 --> 00:19:38,758
Wraps rock wool insulation
Around the gas inlet casing.
307
00:19:38,758 --> 00:19:40,310
It's made of cast iron
308
00:19:40,310 --> 00:19:44,275
And built to withstand gases as
Hot as 900 degrees fahrenheit.
309
00:19:49,206 --> 00:19:52,758
They cover the part with
A heat-resistant fabric jacket.
310
00:19:52,758 --> 00:19:57,310
Then it's ready to be mounted
To the gas outlet casing.
311
00:19:57,310 --> 00:20:01,137
Workers use a crane
To move it into position.
312
00:20:01,137 --> 00:20:04,551
They align the holes in the part
With the threads in the casing.
313
00:20:04,551 --> 00:20:06,517
Then they bolt it into place.
314
00:20:13,448 --> 00:20:19,068
They install a cast iron casing
Around the compressor wheel
315
00:20:19,068 --> 00:20:21,551
And secure it with numerous
Nuts and bolts.
316
00:20:29,724 --> 00:20:31,827
They hoist an insert part
Into place
317
00:20:31,827 --> 00:20:35,172
Between the compressor wheel
And the casing.
318
00:20:35,172 --> 00:20:38,344
Air will flow between the insert
And the compressor
319
00:20:38,344 --> 00:20:43,517
Before traveling to the engine
For combustion.
320
00:20:43,517 --> 00:20:47,448
The turbocharger is now ready to
Be installed in a ship engine.
321
00:20:47,448 --> 00:20:51,206
This is done
In the factory's assembly hall.
322
00:20:51,206 --> 00:20:52,448
Once in place,
323
00:20:52,448 --> 00:20:55,517
They fire up the engine
And test its performance.
324
00:21:00,206 --> 00:21:04,241
They evaluate how much power the
Turbocharger adds to the engine.
325
00:21:04,241 --> 00:21:06,655
They also assess
The turbocharger's impact
326
00:21:06,655 --> 00:21:08,689
On fuel efficiency.
327
00:21:08,689 --> 00:21:11,758
This turbocharger
Meets expectations.
328
00:21:16,482 --> 00:21:20,827
Some cars and trucks use small
Turbochargers in their engines,
329
00:21:20,827 --> 00:21:23,862
But these behemoths should
Deliver twice the air pressure
330
00:21:23,862 --> 00:21:25,137
Of those models,
331
00:21:25,137 --> 00:21:26,965
So the ship's captain
Will have all the power
332
00:21:26,965 --> 00:21:29,448
He needs to navigate
The high seas.
