Hawkish military industry: I started the national defense lottery

The boost-glide ballistics proposed by Mr. Qian is a very powerful ballistics.

It is hard to defend against.

But in the fifty years since Mr. Qian proposed it, no country has ever realized it!

Everyone knows that the boost-glide ballistics is good, but it cannot be realized!

Su Chu said calmly:”Chief Engineer Qian, to be honest with you……I really realized the boost-glide trajectory proposed by Mr. Qian, that is, the Qian Xuesen trajectory!”

When these words came out, the whole audience was in an uproar.

Everyone present looked at Su Chu with surprise, with different expressions, but more or less doubt on their faces…….No one believed that the young Su Chu could actually achieve Qian Xuesen’s trajectory!

Qian Hai was also surprised and said,”This……Su Chu, are you serious?”

Su Chu saw that everyone didn’t believe him, and then he said,”Chief Engineer Qian, of course this is true.”

“It is not impossible to achieve Qian Xuesen’s trajectory. First, our missiles are boosted by rockets like ballistic missiles to reach the”near space””……When the aircraft reaches an altitude of about 20-100 kilometers above the ground, the engine is shut down and the aircraft uses inertia to perform free flight.”

“Then, relying on its own waverider shape, it glides like a cruise missile, using the atmosphere as a booster to fly at high speed in a wave-like manner, and finally re-enters the atmosphere to carry out precise strikes on the target.”

“Qian Xuesen’s ballistic trajectory does not strictly follow a parabolic trajectory……This mode makes the missile’s flight trajectory unpredictable, and the opponent cannot predict the missile’s falling direction, making it difficult to intercept…….In this way, if we build this missile, we can achieve a goal: the launch site is known, the target is known, but the trajectory is unknown, and it is hard to defend against.”

Su Chu just briefly talked about the Qian Xuesen trajectory, and everyone present knew whether Su Chu was capable of realizing it.

Outsiders watch the excitement. Insiders see the doorway.

Su Chu’s words proved that Su Chu was capable.

Obviously, Su Chu’s words once again made everyone’s eyes light up, and they whispered to each other, discussing the possibility of realizing the Qian Xuesen trajectory according to Su Chu’s proposal.

Qian Hai looked at Su Chu and said,”Su Chu, according to what you said, it is really possible to realize the Qian Xuesen trajectory!”

“If we can achieve the Qian Xuesen trajectory, it will be even more powerful than the Sangger trajectory!”

The main principle of the Sangger trajectory is to make the missile repeatedly jump and skip on the edge of the atmosphere, thus achieving the effect of unpredictable trajectory…….The Sangger trajectory has a faster flight speed after multiple jumps, but because its trajectory is at the edge of the atmosphere for a long time, the missile is easier to detect and calculate by radar, and its concealment is much worse than that of the Qian Xuesen trajectory.

This is the advantage and strength of the Qian Xuesen trajectory.

In addition, how to accurately control the timing and posture of multiple entry and exit of the atmosphere is a major technical problem faced by the Sangger trajectory…….At the same time, missiles or spacecraft will generate extremely high temperatures when re-entering the atmosphere at high speed, which puts extremely high demands on thermal protection technology. Therefore, Western countries such as Europe and the United States have not yet achieved the Sanger trajectory.

If Su Chu achieves the Qian Xuesen trajectory, he will be far ahead.

Qian Hai:”Su Chu, it seems that you have done good research on solid fuels, supersonic technology and Qian Xuesen trajectory…….I’ll leave these techniques to you to master!”

“Whatever resources, personnel, funds, etc. are needed, I will do my best!”

Su Chu:”Thank you, Chief Engineer Qian, for your trust and support!”

With Qian Hai’s support, it is not a big problem for Su Chu to realize solid fuel technology, supersonic technology, Qian Xuesen ballistics, etc.

As long as these technical problems are solved, the Dongfeng 17 missile and Dongfeng 21D missile can be built…….This is definitely a killer weapon for aircraft carriers.

In the following period of time, Su Chu mainly led the team to conquer these new missile technologies.

Although Cao Rong and others felt that Su Chu had little experience and was a low assistant researcher, they did their best to assist Su Chu in military research.

Qian Hai also strongly supported Su Chu’s research work!

After all, Su Chu’s ability impressed everyone.

First of all, Su Chu had to solve the missile solid fuel technology.

This was not a difficult task…….After all, the military industry system of a major country has already rewarded solid fuel missile technology, and Su Chu only needs to add and combine the corresponding materials.

The development of solid fuel technology can be traced back to the fireworks invented in the Tang Dynasty several centuries ago…….Since the early 1960s, the Eagle Sauce has gradually replaced liquid propellants with solid propellants and successfully deployed the world’s first solid propellant missile-the Minuteman 1 missile.

Since then, countries such as the Russian Bear and the Gallic Rooster have also developed and deployed solid-fuel missiles.

The rabbit’s research on solid-fuel missiles has just begun.

Since Su Chu is going to develop solid-fuel missiles, he will naturally use the most advanced composite solid propellant.

Composite solid propellant is a multiphase mixture with a polymer as the matrix, mixed with an oxidizer, metal fuel and other additional components.

The oxidizer is the most abundant component in the composite propellant, and the mass fraction generally accounts for 60%-80%. The main function of the oxidizer is to provide the required oxygen for the combustion of solid rocket propellants, and to act as a filler in the adhesive system to increase the Young’s modulus of the propellant…….The oxidant selected by Su Chu is ammonium perchlorate.

Ammonium perchlorate is the oxidant with the best comprehensive performance!

Binder is another important component in composite propellant, generally accounting for 10%-15%……The main function of the binder is to firmly bond the oxidizer solid particles and metal powder together, so that the propellant has appropriate mechanical properties and can withstand the loads during operation, storage, ignition and flight.

At the same time, the binder provides combustible elements such as C and H when burned, which serve as fuel in solid rocket propellants.

The binder chosen by Su Chu is hydroxy-terminated polybutadiene……This is also a good performance.

The addition of metal fuel to solid-fuel missiles is to increase the combustion temperature of solid rocket propellant, thereby increasing the characteristic speed of the propellant and the specific impulse of the engine…….Su Chu’s choice in this regard is naturally aluminum powder.

Aluminum powder has the characteristics of high combustion calorific value, low price, and abundant sources.

In order to improve the energy characteristics, internal ballistic performance, mechanical properties, processability and storage performance of the composite propellant, Su Chu added additional components such as burning rate catalyst, decelerator, plasticizer, enhancer, diluent, wetting agent, antioxidant, and desensitizer.

After some tinkering, Su Chu finally completed the production of solid fuel….
