A big country of aerospace with black technology

"Xing Yang, you guys did a good job!"

After hearing that the error of the missile was only three meters, the old chief patted Zhang Xingyang on the shoulder in half shock and half relief.

Even Zhang Xingyang, who knew in advance that the missile's accuracy could reach the ten-meter level, was a little surprised by this result.

After all, being able to reach the ten-meter level means that the error of the missile will be about ten meters.

But the error was only three meters, which was still beyond everyone's expectations.

"This time it should be an accident. Normally, the error should be around ten meters."

Although the result was very good, Zhang Xingyang was not dazzled by such good news, and still maintained a calm mind as a researcher.

"Even if there is a cost of luck, it still cannot obliterate the success of your technical achievements."

Facing Zhang Xingyang's modest words, the old chief did not hesitate to praise him.

"All of you are heroes!"

"especially you."

Even if he didn't have in-depth contact with the missile research and development process, he got the information according to the old chief.

The entire hypersonic missile, from project approval to research and development, is almost all driven by Zhang Xingyang alone.

Many of the problems encountered here were also solved by Zhang Xingyang.

Not only limited to technical aspects, but also engineering experiments, many of which were solved by Zhang Xingyang.

For example, the most important ram combined cycle engine, which can smoothly transition between sub-combustion, super-combustion and other multi-modes, is all solved by Zhang Xingyang.

But Zhang Xingyang himself didn't have so much emotion.

Zhang Xingyang raised his head to look at the clear blue sky, and said thoughtfully:

"I just did what any scientific researcher should do."

Facing the humble Zhang Xingyang, although the old chief had gotten used to it in the process of being in contact with him over the years.

But still sighed.

"You're still too modest."

"With the hypersonic ballistic missile developed by your Rocket Research Institute, we will be able to speak louder when we face the threat of the enemy in the future."

In this world, the country's strength is the first thing that is valued in exchanges between countries, and in direct confrontation, the most important thing is its own military strength.

Why in the past ten or twenty years, the country has almost always played a harmless image of humans and animals above the international level.

The most important thing is that its own strength is not strong enough.

Only with sufficient force as a backing can one be able to speak loudly in international exchanges.

Facing the proud old chief, Zhang Xingyang thought for a while and said:

"not enough."

"Just this is not enough."

The old chief was a little surprised. After all, in his opinion, the range exceeds 7,000 kilometers, almost reaching the category of intercontinental ballistic missiles. A hypersonic missile with a speed exceeding Mach 7 is almost invincible in the world.

"Why?"

"We also need anti-ship, submarine-launched and other models."

Zhang Xingyang said to the old man in front of him seriously.

The Dongfeng-17 hypersonic ballistic missile tested this time is a ground attack model, mainly used to strike important ground targets of the enemy.

However, as we all know, the main military threat facing the country still comes from the sea.

In particular, the enemy's numerous aircraft carrier battle groups have always been a serious concern for everyone.

This is why Zhang Xingyang puts so much emphasis on anti-ship models, after all, this is a magic weapon that can deal a fatal blow to the enemy aircraft carrier battle group.

"Anti-ship?"

The old chief was a little surprised. After all, anti-ship models of ballistic missiles are not very common these days.

Generally speaking, ballistic missiles are still used to directly attack the opponent's important ground targets.

Especially long-range ballistic missiles equipped with nuclear warheads are all used to attack land targets.

"To be precise, it is an anti-aircraft carrier."

Zhang Xingyang mentioned the specific role of anti-ship missiles.

"The aircraft carrier is the core of the naval battle group. Once the attack is completed, the opponent's battle group will lose more than half of its combat effectiveness."

This point, the old chief is not unaware, but he has some doubts:

"Isn't it easy for an anti-ship missile to break through the air defense and anti-missile system on the opposite side?"

After all, the Yingjiang Navy Aegis system at this time is known as the most advanced air defense and anti-missile system in the world.

Although in its previous battles, except for the mistake of shooting down a civil aviation airliner in 1988, causing 260 deaths, there were no actual actual results.

But it still doesn't prevent everyone from trying to use their imagination to imagine its combat effectiveness to the extreme.

"It's not as difficult as you think."

Zhang Xingyang first gave a conclusion that ordinary people may not accept, and then explained:

"Today's Aegis system mainly relies on the standard series of air defense missiles to intercept flying objects such as aircraft and missiles."

"However, the speed of the standard series of missiles is generally slow, and most of them can only reach the speed of Mach two."

"Compared with our hypersonic missiles, it is almost like a turtle crawling, and it is difficult to complete the interception work."

"Moreover, the standard air defense missile still adopts the method of explosive interception, and the interception effect on hypersonic missiles is very poor."

The best way to deal with hypersonic missiles is to use kinetic energy destruction to ensure that the warhead of the missile can be completely destroyed.

Otherwise, there may be such a situation, that is, although the missile's engine is destroyed, it can still continue to hit the target under the action of inertia.

And because the warhead is not completely destroyed, there will still be a serious explosion.

Yingjiang's army once encountered such a situation in a war. Although the anti-aircraft missile destroyed the engine of the ballistic missile on the other side, it did not completely destroy the warhead, and still caused heavy casualties to itself.

"As far as close-in gun systems, a dozen slow drones might be fine, but hypersonic missiles are basically impossible to intercept."

"So it is very simple for our hypersonic missiles to break through the opponent's anti-missile system."

"In a word, there is nothing to be afraid of."

When Zhang Xingyang said this, his body exuded an arrogance that ordinary people could not imagine.

It seems that Yingjiang, who is extremely powerful in the eyes of others, is just a dead bone in the grave in his eyes.

Zhang Xingyang can't be blamed for having such an attitude. After all, in the era he lived in, Ying Jiang had already split because of his own problems.

become a relatively backward country.

So in his eyes, Ying Jiang had indeed died suddenly.

"The most difficult thing is the problem of guidance."

"The electromagnetic environment above the sea is more complicated than that on the ground because of the influence of waves."

"And a carrier battle group, unlike a fixed ground target, will move throughout the strike."

"This puts higher requirements on the terminal guidance of the missile."

Although the maximum speed of a hypersonic missile can reach fifteen times the speed of sound, in order to accurately hit the target at the end, it still needs to reduce its speed, which is about Mach 8 at most.

For a hypersonic ballistic missile, it takes about 20 minutes from launch to hitting the target.

This time is enough for the aircraft carrier battle group to run 20 kilometers.

The terminal speed of the missile is very fast, which also brings another problem, that is, the time left for the missile guidance system is also very short.

This puts the requirements on the guidance system of anti-ship missiles to a higher level than that of ground attack models.

"However, this problem will not be a problem after our new generation of guided satellites is launched."

Zhang Xingyang smiled after he finished speaking.

"Especially after being combined with our communication satellites, the positioning accuracy can reach the meter level, and the coverage area is much larger than it can only cover the whole country now."

After listening to Zhang Xingyang's discussion on the advantages and disadvantages of anti-ship hypersonic missiles, the old chief thought:

"Do you think there will be a similar hypersonic missile project on Yingjiang's side?"

At this time, although the research and development of hypersonic weapons had already begun within Yingjiang, it was still in the stage of technical demonstration.

They have not yet agreed on the performance parameters that weapons need to achieve.

So now the outside world doesn't know much about Yingjiang's hypersonic weapon project.

This is also the reason why the old chief just speculated that Yingjiang might have such a project.

"There may be, but they still have great difficulties in developing similar weapons."

After all, in Zhang Xingyang's memory, even after more than 20 years, Yingjiang has not been able to complete the development of hypersonic weapons.

Now even if they have a research and development project for hypersonic weapons because of the butterfly effect caused by their appearance.

There will be no particularly big threat, because they have technical shortcomings in many aspects of hypersonic missiles.

"On top of that, they don't have a hypersonic wind tunnel."

In order to develop hypersonic weapons in China, the investment in hypersonic wind tunnels alone has reached more than 10 billion.

This is not counting other facilities supporting the wind tunnel, as well as coal from thermal power plants and so on.

If all the investments are added up, at least 20 billion domestic funds have been spent on the Dongfeng-17 waverider hypersonic ballistic missile!

You know, this is 20 billion in the 2000s!

At this time, the annual fiscal revenue was only more than 700 billion yuan, and 0.3% of it was spent just for this weapon, which is a terrifying figure.

If it weren't for the big head here, the construction funds for the hypersonic wind tunnel would have been snatched from the Western Quantum Fund during the financial turmoil.

The Rocket Research Institute wants to rely solely on its own strength to complete the research and development of such a nationally important weapon.

Don't know when to wait.

Although Rocket Research Institute's current annual income can reach billions, it also has thousands of employees to support, and it is impossible to invest all the funds for several years in this area.

"Even if they want to spend money to build a hypersonic wind tunnel, it's not that easy."

"The difficulty of the shock tunnel is still very high."

If you want to generate a speed capable of testing missiles about fifteen times the speed of sound, the shock wave tunnel is almost the only option in this era.

Other methods are either too difficult or cost too much.

"Even if you take a step back, they have completed the research and development of hypersonic missiles."

"That's at least a few years later."

"That's enough time for us to build our own missile defense system."

Zhang Xingyang said indifferently.

National Missile Defense System, English name National Missile Defense, referred to as NMD.

"How do you think our national missile defense system should be built?"

The old chief asked curiously, he wanted to hear the opinion of Zhang Xingyang, a professional.

"First of all, we need to clarify the defense objects of the missile defense system."

"Our national missile defense system is mainly to defend against hostile ballistic missiles."

"Secondly, at what stage of the missile will we conduct missile defense."

"Whether it is the initial stage just after the missile is launched, or the middle stage of the extra-atmospheric flight, or the end after re-entering the atmosphere."

"From a technical point of view, the effect of the mid-range anti-missile is the best."

"If we are going to build a missile defense system, the most important thing is to build a mid-course missile defense system."

"Because during this period of flight, the trajectory of the missile is very stable, and it is easier to be predicted by supercomputers."

"In the end it's the way the missiles are defended."

"As I said just now, the way the missile explodes and destroys, the defense effect is average."

"So if you want to achieve the effect of complete destruction, it is best to use the method of kinetic energy destruction."

"Using high-strength alloys, it relies on its own kinetic energy to completely destroy incoming missiles."

Then Zhang Xingyang described to the old chief the working picture of the national missile defense system to be established in the future.

After the enemy's ballistic missiles took off, the detection equipment on the space satellite first detected their missiles taking off.

The information is then transmitted to the 24-hour information command center on duty, after the command center has determined the enemy's attack.

Issue an order to start the anti-missile missile to prepare for launch.

At the same time, the command center transmits the data detected by the reconnaissance equipment to the supercomputer to calculate the trajectory of the incoming missile.

Because ordinary ballistic missiles will not adopt the unique domestic Qian Xuesen trajectory, 70% of the flight segment is outside the atmosphere, and during this period, the flight trajectory is stable, and the supercomputer can easily calculate the missile's flight trajectory.

After analyzing the trajectory of the missile, the data is transmitted to the on-board computer of the anti-missile missile.

After the anti-missile missile receives the data, it ignites and launches, and lifts off.

Because the range of anti-missile missiles is often overflowed, the missiles are in the initial stage of lift-off.

It is necessary to perform a large-angle spiral in the sky to consume excess fuel.

In the sky, a very weird image was drawn, which made people very puzzled.

After the spiral is complete, the excess fuel is consumed.

The anti-missile missile starts to accelerate and will climb to altitude.

All the way up to the same exo-atmospheric altitude as the incoming ballistic missile.

And under the guidance of the on-board computer, it directly collided with the incoming ballistic missile!

To achieve the purpose of destroying incoming ballistic missiles. (end of this chapter)
