Chapter 369: Different shapes

The No. 8 assembly workshop covers an area of ​​200,000 square meters, and the length of the gate alone reaches 300 meters.
The height of the factory has also reached 40 meters, as high as a twelve-story building.
This length and height can already accommodate any aircraft in the world, even if the An-225 is over, it can be installed very easily, and there is still a lot of space left.
This size is the most basic size of the war factory, which can assemble two large aircraft at the same time.
Now inside, there are also two passenger planes, one large and one small, which have been assembled, and all the avionics and lines inside have also been overhauled.
At the same time, behind the No. 8 workshop, the other four workshops in the second row are also being constructed.
Non-red police units can use this assembly method for production, unlike red police units, they must only use base production lists for production.
This kind of production can not only separate the non-red police units from the red police units, but also allow all non-red police units to produce quickly.
Because production is not on the list, so only your assembly speed is fast enough, the production efficiency can be as fast.
It all depends on the number of engineers and factories. With more engineers and factories, the speed of assembly will naturally increase.
The two passenger planes were assembled in less than half a month. All the parts and modules were transported from the war factory below. They only needed to complete the assembly of the entire body on it.
There is no need to lay lines, nor do those interior trims. These things are all produced in the process of modular production.
In the process of assembling each module, those lines and equipment will be automatically connected, and there is no need to reinstall any equipment in it.
Air-conditioned seats, toilets, etc. are all readily available, as well as those oxygen masks and life-saving equipment.
That's why the assembly work can be completed so quickly. Finally, the overall spraying is enough.
And this kind of spraying is just a coat of paint. Because of the modules themselves, there are already multiple layers of protective coatings.
The last layer of acoustic paint is just a protective coating for the exterior of the aircraft, which protects the paint inside.
When the doors of three hundred meters long were all opened. All kinds of equipment inside have also appeared in the eyes of the world.
Only the equipment inside is quite disappointing. Because the aircraft assembly workshops of various countries are basically the same.
Some hoisting equipment, already those assembled mechanical platforms. There is a black passenger plane inside.
Airliner painted in black, this color. This is the first time I have seen it in the world.
This kind of black is not just the darkening of those gray colors, but directly black and shiny.
The whole world knows it. The painting on the plane is very particular, and the color is also very particular.
but. For a passenger plane, painting it in black is not a big deal.
It's not those fighters, the black target is huge. Easy to expose yourself.
If it is a passenger plane, black is very easy to identify, but this color is not used by anyone because it is not a reason. It's still a matter of personal preference.
However, one thing is certain, the cost of black painting will be relatively high, especially the cost of black and shiny painting is definitely higher than those of light-colored painting.
The first trailer slowly backed up and, with the help of the staff, hooked the nose gear of the first passenger plane.
The horsepowered trailer easily pulled the passenger plane from the hangar. Then the speed machine dragged it out of the hangar slowly.
The first aircraft was not very big. Compared with Airbus and Boeing models, it was a little bigger than the 737 or A320. The black paint covered 80% of the body.
But behind the wing and the vertical tail, it is painted in gray, which seems to distinguish those positions for adjusting the aircraft's heading height.
However, what really caught everyone's attention was that the two long wing ends of this aircraft were folded upward, but the engine under the wing was not seen.
However, the sharp-eyed people quickly discovered that under the junction of the wing and the fuselage of this aircraft, there are two huge clam-shaped air inlets.
Obviously, this passenger plane is not without an engine, but the engine is behind the plane.
Sure enough, when the aircraft was slowly dragged out of the hangar, everyone saw that there were two engine tail nozzles at the tail of the aircraft, under the tail radome.
This kind of airliner shape is absolutely novel, because almost no airliner has the opportunity to adopt such technology.
It's not that this technology is not good. On the contrary, this technology is very beneficial to the aerodynamic layout of the aircraft. After all, there are two more engines under the wings, which will increase the air resistance.
This is why all fighter jets have engines behind them, which is conducive to high-speed flight of the aircraft and fuel saving, and also contributes to the rate of climb.
However, the main problem with this layout of aircraft engines not appearing on passenger planes is that the construction cost will be higher.
After all, a complete fuselage, plus a vertical tail and two wings and engines under the wings, is the simplest structure.
It is convenient to construct and the production price is much cheaper.
The main problem is that it is good for maintenance, because the engine is not wrapped in the fuselage of the aircraft. During maintenance, the aircraft engine is also under the wing, which is mutated and disassembled for inspection.
At the same time, there are inspections on the plane before the flight.
The disadvantage is that for passengers in the airport ~EbookFREE.me~ the engine under the wing, the sound of the aircraft engine is too loud.
At the same time, the climb rate is not high and the aircraft consumes more fuel.
Choosing an engine layout similar to that of a fighter jet can increase the climb rate of the aircraft, and the sound in the airport will be much smaller.
Especially after the subsonic flight, due to the rear engine, people in the front cabin will hardly feel the sound of the rear engine.
At the same time, such a passenger plane is also conducive to taking off within a shorter distance, and when landing, the taxi distance will be shorter.
Moreover, this aerodynamic layout can make the aircraft look simpler and more fashionable, which is more in line with human aesthetics.
Especially in the process of technological development, the more advanced things, the more beautiful they often look.
Future Technology Group uses some of the fighter jet designs on passenger planes, and it can only be said that the local tyrants are very willful.
Of course, the most important thing is that this is a manifestation of Future Technology Group's absolute trust in its own technology. (To be continued.) Enable new URL
