Doomsday Bunker Upgrade

Chen Xin was very interested in the research and development of the new aircraft.

For him, coming up with a new plane only depends on whether his imagination is rich enough, not on other conditions.

However, Chen Xin can't open his mind too much. After all, he has to consider the problem of actual production. Even if Chen Xin can make the X-wing starfighter in "Star Wars", the country can't even make a lightsaber.

This is the gap between the industrial system and the overall technology, which cannot be made up by simply relying on Chen Xin's opening.

Therefore, even if Chen Xin wants to design a new fighter jet, he must consider the country's industrial production capacity. In addition to the design problems, whether a new fighter jet can be built or not, there are also many factors such as cost and technology.

This also leads to Chen Xin not using too exaggerated technology, it is best to design and develop on the basis of existing technology.

For Chen Xin, it is very easy to make the design of the new aircraft advanced. After all, there are so many sci-fi works, and just copying one can be done by relying on the system.

But to make the new plane more realistic and less advanced... it takes some thought and design.

Fortunately, the place where Chen Xin was at this time was the temporary capital of the Yan Kingdom. There were a lot of scientific research forces and related materials here, and Chen Xin just had the authority to call these materials.

Of course, Chen Xin couldn't understand the specific scientific research materials, but people could sort out a technical catalog and introduction that Yan Guo could use in the field of aircraft manufacturing, and Chen Xin could still find what he wanted.

The most important thing in an aircraft is of course the engine known as the heart.

Yan Guo was not able to use fighter jets all the time. The biggest problem was the performance of the engine, production and R\u0026D capabilities. Not having a self-developed engine with reliable performance was once a huge regret for Yan Guo in the aviation field.

Later, after the efforts of countless people, Yan Guo finally made a breakthrough in this field, and the manufacture and research and development of the engine finally achieved fruitful results.

However, for the new aircraft, Chen Xin does not intend to use existing aircraft engines.

The reason does not need to be repeated. Chen Xin is optimistic about the electric propulsion system originally used in the aerospace field, also known as the ion thruster.

To put it simply, the working fluid is electrolyzed into charged particles by electrical energy, and then thrust is obtained by accelerating the charged particles.

This is also a relatively common engine in science fiction works. It is usually used in space vehicles, and it is not considered to use this thing in the atmosphere.

This is mainly because the thrust that the ion thruster can generate is too small, or the power is too high.

The ion thruster can accelerate charged particles to tens, hundreds of kilometers per second, or even higher. In this case, if a relatively large thrust is to be generated, the power required by the ion thruster will be very large, and at the same time It also requires an equally huge amount of energy to drive it.

Taking the current relatively mature technology on Bluestar, if the power of the ion thruster is increased to 200KW, it can generate a thrust of about 0.45 kilograms. Although it is inconspicuous in the atmosphere, if it is raised into space, After getting rid of the influence of gravity, this thrust is enough to push a 2-ton weight.

Of course, this is limited by the original technological level of Blue Star.

With the nuclear reactor technology currently mastered by Yan Guo, it can already provide a micro-reactor with a power of more than 10MW that can be mounted on an aircraft, which is enough to provide sufficient energy for the engine.

What Chen Xin has to do is to reduce the speed of the jet of the ion thruster, thereby increasing its thrust.

This is the same principle that a jet engine reduces the speed of the jet and increases the thrust of the engine.

Kinetic energy Ek= mv^2/2, momentum=mv, thrust is determined by momentum.

For aero-engines, the external exhaust is the lost energy.

When the momentum mv remains unchanged, reducing the exhaust speed can reduce the energy taken away by the exhaust and improve the efficiency.

In the same way, keeping the momentum constant and reducing the exhaust velocity requires a larger mass of the working fluid, that is, more air is sucked in.

So in layman's terms, if an aero engine wants to be efficient, it needs to push a lot of air at low speed.

However, for the ion thruster, although the principle is clear, its demand for air, that is, the working medium, is far lower than that of ordinary aero-engines.

The current consumption of the working medium per second by the current ion thruster is at the milligram level, and the thrust generated is at the level of 0.1 N. If this value is enlarged to the extent that it can meet the thrust requirements required by the jet fighter, the consumption of the working medium will be reduced. Still not worth mentioning.

Taking the Taihang engine independently developed by Yan Guo as an example, its thrust can reach 13.5 tons, which is 132,300 N in cattle, and the corresponding working medium consumption is about 0.13 kilograms per second.

The consumption of this working substance is definitely not large. Taking the same ethereum engine as an example, its air intake is 118kg/sec, which is almost a thousand times that of an ion thruster.

Therefore, under the premise that air is also used as the working fluid, the air intake required by the ion engine is quite insignificant, even similar to that of an ordinary family car.

As for the power that restricts the use of ion thrusters in the atmosphere, it is no longer a problem in the face of the abundant power provided by small nuclear reactors.

After solving the problem of the engine, for an aircraft, the rest is nothing more than some details such as aerodynamic layout and structural design, and these details can be solved by the classic physical method of flying bricks.

As long as the power is enough, no matter how bad the aerodynamic layout and structural design are, it can fly, as long as it doesn't fall apart.

Of course, Chen Xin hasn't lost his mind to such a degree that he intends to do some great flying bricks, and he still intends to design the shape of the aircraft.

It's just that as a non-professional, he considers more handsome appearance, not rationality.

Although according to a causality boss, better appearance also means more advanced technology, but for ordinary aircraft designers, appearance still needs to accommodate technology.

But for Chen Xin... With a system in place, even if he builds a Gundam, he can still go supersonic, so in the design of the plane, he can focus more on looks rather than technology.

After some brainstorming and reference to existing science fiction works, the final design Chen Xin finally came up with looks more like a space fighter than a fighter used in the atmosphere. Not round at all.

And the most important thing is that the three propellers installed by Chen Xin on the aircraft, two of which are installed on the wings, which can be completely different from the existing fighter design layout.

Ion thrusters are currently widely used on satellites and spacecraft, but the power is really small
