The military-industrial scientific research system of the academic master.

At this moment, Brigade Commander Wei Shijun also came running from a distance.

In fact, he had been trying to get here since Chang Haonan and Chang Haonan first came face to face, but the celebrating crowd was too crowded, so he was delayed a little.

"Academician Chang, this is Researcher Dai Pengxin who is currently conducting research at our base. He was previously with a sister unit...but it just so happens that our brigade has a launch mission today, so the entire base has sent representatives to observe..."

Chang Haonan smiled and waved his hand:

"Researcher Dai has already introduced himself. He and I are in the same field."

Dai Pengxin also followed up by explaining:

"You know, the ballistic missile with mobile penetration capability was developed based on the Type 21 missile. As the developer, we also need to understand how the frontline units use it..."

As an independent branch of the military, the Second Artillery Corps adopted the army-brigade-battalion organization from the very beginning.

As of 2005, each army-level base generally has 3-7 missile brigades under its jurisdiction, and each brigade contains 12 launch battalions, which are literally "one gun for the whole battalion."

Of course, the base is too large and is usually not used as a combat unit like the army group of the big brother army. It just concentrates the missile forces under the jurisdiction of a single military region to facilitate administrative management.

Therefore, the equipment models of different brigades in the same base are not exactly the same.

For example, the main object of Dai Pengxin's visit and investigation is most likely the 21 Brigade next door, which is equipped with the newer Dongfeng 822.

He has always been the envy of the officers and soldiers of the 810th Brigade.

However, at least today, Brigade Commander Wei's mentality is still relatively balanced.

After all, they had the opportunity to fire a precious live round, which was in some ways due to the fact that their equipment was old enough...

After a brief greeting, Wei Shijun knew that he had no say in the specific technical matters, so he quickly found a reason to command the launch battalion to withdraw, put on his gas mask again and turned to leave the command post.

The other two quickly returned to the previous topic.

"In fact, at the beginning, our idea was to make the warhead roll at high speed during flight. This would stabilize the trajectory while consuming some of the reentry energy, thereby reducing the reentry speed. On the one hand, this would allow time for attitude adjustment, and on the other hand, it would also try to reduce the thickness of the plasma sheath..."

Dai Pengxin introduced:

"However, after actually simulating the control rate, we found that the slider and guide rail inside the warhead will exert a large inertial torque on the warhead during rotation, resulting in a very strong coupling effect between the control rates of the roll channel and the pitch channel. Therefore, we can't take shortcuts like this, and we still have to consider a more direct approach..."

Chang Haonan was a simple aviation engineer in his previous life, so he had no in-depth exposure to the research and development process of anti-ship ballistic missiles.

However, even from some fragmentary words, he had heard of the idea of ​​"hitting a moving target by reducing the re-entry speed."

But now it seems that the research was probably stopped halfway through.

Although Chang Haonan probably won’t have the chance to know how the technicians in his previous life finally solved this problem.

But fortunately, he now has his own way.

Moreover, the ideas previously proposed by the Second Hospital may not be without value...

"Different types of warheads have their own specific characteristics. All I can say now is that, in principle, self-sweating materials can indeed directly reduce the surface temperature. But if you want more specific data, it would be better for the two project teams to cooperate after we return to the capital."

Chang Haonan first gave a conventional response.

Dai Pengxin had only just had some initial contact with Chang Haonan, so naturally he nodded repeatedly.

But before he could open his mouth, the latter changed the subject:

"In addition, if you are sure you want to cooperate with us, it would be best if you could also include your previous research results on rolling deceleration and variable center of mass maneuvers."

"Oh?"

This request obviously exceeded Dai Pengxin's expectations:

"Academician Chang, your research... also requires the use of variable center of mass maneuver technology?"

"For hypersonic weapons, the control torque that the metamass center can provide is too low...so it is not used for maneuvering..."

Chang Haonan shook his head and continued to explain:

"Based on our research results on the double-cone warhead, the interference torque on the missile can be converted into a rolling acceleration interference term and introduced into the closed loop of the autopilot. If it can be combined with slider control, it can be used to offset the external interference term and improve the terminal hit accuracy."

After hearing this idea, Dai Pengxin pondered for a moment, as if he could not keep up with Chang Haonan's problem-solving ideas, which were as flexible as a loach.

But the latter's explanation just now is quite general, so it is impossible to analyze it in detail.

He had no choice but to convince himself and temporarily accept this setting:

"Then Academician Chang, I will report this to the higher-ups as soon as I get back..."

……

While the 810th Brigade was celebrating the successful launch and began to collect and analyze the full-range data, the interception test results of the surface-to-air missile were also sent to the Air Force leaders who were in a meeting.

Obviously, the situation is not optimistic.

Even though the target's attack direction and time were known in advance, they were unable to complete even the most basic shooting preparations.

If it were under actual combat conditions, the air defense position itself, or the important target it protected, would most likely have been destroyed by this one attack.

Although everyone has previously estimated the power of hypersonic weapons, a simple thought in the mind is not as intuitive as the results of confrontation tests written in black and white.

After a long silence, Qiao Chenqing adjusted his sitting position and asked Sun Zhejun, the director of the Air Force Political Department next to him:

"This Captain Lu Zhicheng, I remember, was the one who successfully passed the acceptance test by hitting seven out of seven during the target practice in Suzhou last year?"

The latter nodded:

"That's right, but all the personnel in Suzhou were highly qualified, so Comrade Lu Zhicheng was actually in charge of commanding the missile launch company. He is one of our army's most experienced commanders in the field of anti-missile interception..."

Hearing this, the expressions of the other people around the conference table changed slightly.

The most experienced commander in the entire army, equipped with the most advanced air defense system currently available.

As a result, even stable tracking cannot be achieved.

This can certainly no longer be said to be a subjective issue.

It should be said that with the arrival of a batch of new equipment in recent years, the Air Force was already quite confident in the level of air defense in key areas.

Especially after last year's test, which proved that the latest generation of air defense missiles are capable of defending against medium- and short-range tactical ballistic missiles, they breathed a sigh of relief after a long time.

As a result, less than a year after we let out the sigh of relief, we have to tighten our belts again.

"Comrade Lu Guang."

Qiao Chenqing looked at the head of the Air Force Equipment Research Institute who was sitting at the end of the conference table:

"Do you think...the latest air defense system we are developing can effectively deal with this kind of ultra-high-speed target?"

Lu Guang had actually guessed that he would be asked this question, but he still pretended to think for a while to avoid appearing too frivolous:

"The basic Hongqi 9 was delivered to the troops for trial at the end of last year. The current feedback is that except for the shorter range, its other performance is roughly the same as or stronger than the S300PMU2..."

"But these two systems are still essentially the same generation of products. Our research and development focus at that time was also to strengthen the ability to deal with multi-frequency and ultra-low-altitude targets... If faced with high-speed ballistic targets, there will probably be no essential difference in performance..."

His answer was quite euphemistic, but the meaning was not difficult to understand:

No.

Qiao Chenqing couldn't help but reveal a somewhat distressed expression:

"It seems that this new three-on-three defense is a bit outdated... We need to study the 'new new three-on-three defense'."

Although the words were somewhat humorous, no one present could laugh.

Seeing this, Lu Guang comforted everyone a little:

"At least now, the research on hypersonic weapons by various countries is still in the verification stage, so the situation is not as tense as it was more than ten years ago..."

His words had some effect.

After all, in order to protect the major coastal cities, the air defense forces were forced to pull out even the Type 59 anti-aircraft guns.

But comfort is just comfort after all.

The Chinese army has always been prepared for danger in times of peace.

"A great man once said that we should despise the enemy strategically, but take the enemy seriously tactically. The technological strength of the Americans should not be underestimated... Their research on hypersonic weapons should still be ahead of us at present."

At this point, Qiao Chenqing paused for a moment:

"Comrade Lu Guang, if we assume that the U.S. military is equipped with hypersonic missiles like this in the next few years and defines it as a tactical weapon, what is a more reliable way to deal with it?"

It should be said that, from the perspective of the time point of 2005, his analysis is actually quite reasonable.

Although there are indeed no models that have been equipped to the troops, the U.S. Army, Navy, Air Force and NASA have all established their own hypersonic research institutions.

No matter how you look at it, it's a bustling and prosperous scene.

This time, Lu Guang's answer was also very quick:

"The only way is to develop an air defense system specifically for anti-missile defense, just like the United States and the Soviet Union did back then!"
