Great Power Heavy Industry: Rise

Chapter 137 Russian Matryoshka Dolls

Subsequently, Zhong Chengcheng and Fu Huaquan selected eight candidate graduate students in the personnel management system.

Although the conditions were not as stringent as Zhong Cheng had proposed at the beginning, they basically met the first three conditions.

Because the military training hadn't been completed yet, Zhong Cheng and Fu Huaquan agreed that these people would be sent directly to him if they passed the military training.

At this moment, Zhong Cheng regretted that all the new recruits he proposed had to participate in military training.

If these eight people fail the military training, should he want it or not?
……

9 month 8 day.

In the conference room on the ninth floor of "Tianwaitian", Zhong Cheng held a team seminar, which was the first official meeting of the Suzaku Fighter Project.

In the past half a year, although everyone was also exploring the design of the Suzaku fighter, they were distracted by various things and did not conduct a comprehensive analysis and discussion.

Zhong Cheng listed the expected performance of the Suzaku fighter that he introduced before the Spring Festival this year on the projector, and everyone discussed the feasibility one by one.

The first thing to solve is the 30-ton take-off weight of the Suzaku fighter, which is ten times higher than the 3-ton take-off weight of the Jingwei unmanned fighter.

Only when this problem is solved can other issues be discussed.

Zhongcheng originally designed it with 100 sets of Kuafu II power batteries and 100 new Zhurong electric pushers to provide power.

After discussion, everyone thought that although the power and thrust were sufficient, it was not feasible.

Because the weight of this power system has reached 8 tons, not to mention, the volume cannot be tolerated.

Although the volume of a new Zhurong electric pusher is only the size of a shoe box, and a set of Kuafu II power batteries is also the size of a microwave oven, 100 sets will take up more than one-third of the internal space of the Suzaku fighter.

This is not counting the space occupied by the corresponding control circuit system. If Fuxi optical brain, weapons, radar, refrigeration, supercharging and other systems are added, I am afraid that only a monkey can be placed in it to drive.

Moreover, the 100 Zhurong electric pushers are densely arranged, the thrust is not concentrated, and there is mutual interference.

The power battery is easy to handle. The old method is dismantled and reorganized, which can save some space and weight.

But Zhurong’s electric push will not work. This is an ion engine with an ionization chamber and an electron gun as its core, and it is impossible to dismantle and reassemble it.

There are only two ways to solve it, either miniaturization or large-scale.

Everyone discussed it, and first of all, they rejected the miniaturization method. First, it was too difficult, and second, it did not solve the fundamental problem.

Zhurong Electronic Push is now small enough. A large number of components are integrated in the space of a shoe box. If it is smaller, the only way is to take the route of nanotechnology. This is not a problem that can be solved in a few years.

And everyone thinks it is unnecessary. Ion engines are mainly used in large aircraft, and maybe they will be used in outer space flight in the future.

So now to carry out large-scale, can be regarded as preparation in advance.

Liu Yuzhu first suggested that it would be enough to just increase the size of Zhu Rong's electric push, but was immediately refuted by Jiang Yan.

The increase in the volume of Zhu Rong's electric pusher is not proportional to the increase in thrust. She has done a simulation on Fuxi No. 0.4, doubling the volume and adding [-] times the thrust at most.

Moreover, in the current structure of Zhurong electric pusher, the volume increase is also limited. When the volume is increased to 5 times, the engine will not be able to withstand the huge power input, and various failures will occur, so it must be redesigned.

Moreover, the performance of the body material should be further improved, and the difficulty is not much less than miniaturization.

Just when Liu Yuzhu was speechless, Yang Xi proposed a solution.

In fact, this is a question he has been considering. He believes that an ion engine that provides more than one ton of thrust is far from his goal.

His method is to make the Zhurong electric pusher into a ring form, just like a Russian nesting doll, except that the diameter is different and the length is the same.

Except for the innermost ionization chamber which is cylindrical, the other ionization chambers are in the form of thin-walled rings separated by chaotic alloys.

The final spray port has also changed from a cup mouth shape to a collar shape.

If you push 10 Zhu Rong electrics together, the volume will only increase by less than 5 times compared with one, and the driving force will not decrease too much.

The simulation result is 9 times, that is, a thrust of nearly 10 tons. With 5 such large Zhurong electric pushers, it can provide a thrust of 50 tons, which is completely sufficient.

The difficulty of this scheme lies in the design of the electron gun, and a distributed electron gun array must be used.

Originally, there were only 10 electron guns, but now at least 160 electron guns are used, and the more the better, the power conversion efficiency is higher, and the thrust of 50 tons can be increased.

Of course, if only the electron gun is miniaturized, the difficulty is much smaller.

Zhong Cheng is overjoyed, this idea is very good, and there is a huge room for improvement, that is, you can set up a few more "babies".

This kind of large-scale Zhurong electric pusher is not only for the Suzaku fighter jet, but also for the large-scale aviation passenger aircraft he imagined.

After everyone's discussion, it has been passed, and this 'Russian nesting doll' scheme is adopted.

The power system problem is solved, and everything else is easy to handle. The laser cannon directly uses the Xingtian laser cannon used on the Jingwei drone, and the Houyi electromagnetic gun, Jiang Yan, is already in the development process.

Jiang Yan introduced the Houyi electromagnetic gun she designed. In fact, the principle of the electromagnetic gun is very simple.

Two conductive rails, and then a conductive body is placed horizontally, so that an electromagnetic gun is formed, and the horizontally placed conductive body is the shell.

A current is connected to two parallel conductive tracks, so that a current flows on the horizontal conductors.

Then, because the current on the two parallel tracks can generate a magnetic field (Ampere's law, Biot-Savart's law), there is a Lorentz force, which can push the transverse conductor to move.

Electromagnetic gun is a kind of advanced kinetic energy killing weapon made by using this principle.

Unlike traditional cannons, which use gunpowder gas pressure to act on projectiles, electromagnetic guns use the Lorentz force generated by the electromagnetic field in the electromagnetic system to accelerate metal projectiles so that they reach the kinetic energy required to hit the target.

Electromagnetic guns can greatly increase the speed and range of projectiles compared to traditional gunpowder-propelled cannons.

Electromagnetic guns are mainly composed of energy, accelerators, and switches. According to different accelerators, they are divided into two types: coil guns and rail guns.

The Houyi electromagnetic gun designed by Jiang Yan is a coil gun.

Coil gun, also known as AC coaxial coil gun, is the earliest form of electromagnetic gun, which is composed of accelerating coil and projectile coil, and works according to the interaction principle of magnetic field between electrified coils.

Although the shells fired by coilguns are much lighter than railguns and have similar speeds, they have an obvious advantage in that they are small in size and do not require the acceleration track of a railgun to be tens of meters long.

Very suitable for use on fighter jets.

In the past, it could not be practical because there was no suitable power supply, and it had to rely on its own generator for power supply. It was difficult to miniaturize, and it could only be used on large warships.

Now with the Kuafu II power battery, it is possible to realize the airborne electromagnetic gun.

Although the Houyi electromagnetic gun only uses alloy projectiles weighing 50 grams (one or two), its flight speed can reach more than 3000 m/s, and it can easily penetrate 100 mm thick steel plates. It can be said to be indestructible under continuous firing.

The only problem now is that the launch speed is still too slow.

Only two bullets can be fired per second, which is equivalent to the continuous firing speed of a rifle, which is much slower than the most advanced "Metal Storm" machine gun firing 100 million bullets per minute.

(PS: At present, the firing speed of large electromagnetic railguns is about 10 seconds to fire a shell. Of course, this railgun fires large alloy projectiles weighing tens of kilograms.)
"But the power is different. The machine gun bullets can penetrate 20mm steel plate and 1 meter thick reinforced concrete fortification at most!" Liu Yuzhu encouraged Jiang Yan from the side.

Zhong Cheng also persuaded, "Improve the loading method and coil structure, not to mention tens of thousands of rounds per second, hundreds of rounds will be powerful enough."

Jiang Yan nodded, "I will work hard!"

Even if the matter of weapons is settled.
