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 also reached 40 meters, which is as tall as a 12-story building.

This length and height can already accommodate any aircraft in the world, even if the An-225 comes over, it can be easily loaded in, 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 equipment and wiring in them have also been overhauled.

At the same time, behind the No. 8 workshop, four other workshops in the second row have also begun to be built.

Non-Red Alert units can use this assembly method for production, unlike Red Alert units, which must only use the base production list for production.

This kind of production can not only separate non-red police units from red police units, but also allow all non-red police units to produce quickly.

Because production is not on the list, only if you assemble fast enough, the production efficiency will be as fast as possible.

It all depends on the number of engineers and factories, and the more engineers and factories, the faster the assembly will be.

The two passenger planes have only been assembled for less than half a month, and all the parts and modules are all transported from the war factory below, and they only need to complete the assembly of the entire airframe on it.

There's no need to lay wiring, there's no need to do those interiors, it's all in the process of modular production. It's all produced.

And in the assembly process of each module. Those lines and equipment. It will be automatically connected, and there is no need to reinstall what devices are in it.

Air-conditioned seats, toilets, and so on, all of them are available, as well as those oxygen masks and life-saving equipment, and none of them are missing.

That's why the assembly work can be completed so quickly, and finally the overall spraying can be carried out.

And this spraying is only a one-time paint, because the modules themselves already have multiple layers of protective coating.

The last layer of sound paint. It's just the exterior protective coating of the aircraft, which plays a role in protecting the paint inside.

When the 300-meter-long gate was opened, all the equipment inside appeared in the eyes of the world.

It's just that the equipment inside is quite disappointing, because the aircraft assembly workshops in various countries are basically like that.

Some hoisting equipment, already those assembled mechanical platforms, and there is a black airliner inside.

It is the first time in the world that a passenger plane painted in black has seen such a color.

This kind of black. It's not that the gray color is darkened, but the black is shiny.

The whole world knows it. The paint on the plane is very particular, and the color is also very particular.

However, for an airliner, it doesn't really matter if it's painted black.

It's not those fighters, who say that the black target is huge and easy to expose themselves.

If it is a passenger plane, black is still very easy to recognize, but this color, the reason why no one uses it, is because of some reasons that are not reasonable. It's still a matter of personal hobbies.

However, one thing is for sure, the cost of black painting will be relatively high, especially the cost of painting in black and shiny, which is definitely higher than that of those in light colors.

The first trailer slowly retreated, and with the help of the crew, hooked the nose landing gear of the first airliner.

The trailer with full horsepower easily dragged this passenger plane out of the hangar. Then the speed machine slowly dragged it out of the hangar.

The first aircraft was not very large, a little larger than the 737 or A320 compared to the Airbus and Boeing models, and the black paint covered 80 percent of the fuselage.

However, behind the wing folds and vertical tail, they are painted in gray, which seems to distinguish those positions that adjust the aircraft's heading altitude.

However, what really caught everyone's attention was that the two long wings of this plane were folded upwards at the ends, but the engines under the wings were not visible.

However, sharp-eyed people soon discovered that under the junction of the wings and the fuselage of this aircraft, there were two huge clam-type air intakes.

It is clear that the airliner did not have an engine, but that the engine was in the back of the aircraft.

Sure enough, when the plane was slowly dragged out of the hangar, everyone saw that in the tail of the plane, under the tail radar fairing, there were two engine tail nozzles.

Such a passenger aircraft shape is definitely a novelty, because almost no passenger aircraft will use such technology.

It's not that this technology can't be used, but it's 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 fighters have engines in the back, which is conducive to the high speed of the aircraft and fuel saving, and also helps the rate of climb.

However, the main problem why aircraft engines of this layout did not appear on passenger aircraft is that the construction cost will be higher.

After all, a complete fuselage, plus a vertical tail and two wings and engines under the wing, is the simplest structure.

It is easy to build, and the production price is much cheaper.

The most important problem is that it is conducive to maintenance, because the engine is not wrapped in the fuselage of the aircraft, and the aircraft engine is also under the wing during maintenance, and the mutation is disassembled and checked.

There is also a pre-flight inspection of the aircraft.

The disadvantage is that the engines under the wings, the aircraft engines are too loud for passengers in the airport.

At the same time, the rate of climb is not high, and the aircraft is more fuel-guzzling.

Choosing an engine layout similar to a fighter jet can increase the climb rate of the aircraft, and the sound in the airport will be much quieter.

Especially after flying at subsonic speeds, people in the front cabin will hardly feel the sound of the rear engines due to the rear engine.

At the same time, such an airliner is also conducive to take-off in a shorter distance, and when landing, the taxiing distance will be shorter.

Moreover, such an aerodynamic layout can make the aircraft look more simple and fashionable, which is more in line with human aesthetic views.

Especially in the process of technological development, the more advanced something is, the more beautiful it often looks.

Future Technology Group uses some of the designs of fighter jets on passenger aircraft, which can only be said to be very capricious.

Of course, the most important thing is that this is the absolute trust of Future Technology Group in its own technology. (To be continued.) )
