Chapter 1187 A new confrontation mode
At this time, Brigadier Wei Shijun also came rushing from a little distance away.
Actually, he had been moving here since the first time Chang Haonan and I met face to face. It was just that the crowd celebrating was too crowded, so it was delayed a little.
"Academician Chang, this is Researcher Dai Pengxindai who is conducting research at our base, but he has been with a brother unit before... It’s just that our brigade has a launch mission today, so the entire base is Representatives were sent to observe..."
Chang Haonan smiled and waved his hand:
"Researcher Dai has introduced himself just now, and he and I are colleagues."
And Dai Pengxin also explained immediately:
"You know, ballistic missiles with the ability to maneuver through defenses, It is developed on the basis of the Type 21 bomb. As a developer, we also need to understand the use of front-line units..."
As an independent arm, the Second Artillery Corps has adopted the military-brigade- How the camp is organized.
At this time in 2005, each military-level base generally had 3-7 missile brigades under it, and each brigade contained 12 missiles in the literal sense of "one gun for the whole battalion" Launch camp.
Of course, the unit of the base is too large. It is generally not used as a combat unit like the army of the big brother of the army. It just concentrates the missile forces under a single military region together, making it easier to manage administratively.
So the equipment models among the brigades in the same base are also different.
For example, the main target of Dai Pengxin’s visit and investigation is most likely the 822 Brigade next door equipped with the updated Dongfeng 21.
He has always been the envy of the commanders and fighters of the 810th Brigade.
However, at least today, Brigadier Wei's mentality is relatively balanced.
After all, they had the opportunity to fire a precious live ammunition, to a certain extent, it was a blessing that the equipment in their hands was old enough...
After a brief exchange of greetings, Wei Shijun also knew that he could not intervene in specific technical aspects. Why are you talking, so I quickly found a reason to command the launch battalion to withdraw, put on the gas mask again, and turned around to leave the command post.
The other two people quickly returned to the topic just now.
“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 part of the reentry energy, thereby reducing the reentry speed. On the one hand, it would give the attitude Allow time for adjustment, and on the other hand, try to weaken the thickness of the plasma sheath..."
Dai Pengxin introduced:
"However, after actually conducting control rate simulations, we found that the slider and guide rail inside the warhead will exert a large inertial moment on the projectile during rotation, resulting in a very strong difference between the control rates of the roll channel and the pitch channel. The coupling effect, so there is no way to be opportunistic, or to consider a more direct method..."
Chang Haonan was a pure aerospace engineer in his previous life, so he did not have in-depth contact with the research and development process of anti-ship ballistic missiles .
But even from a few words, he had heard of the idea of "hitting moving targets by reducing reentry speed."
But looking at it now, I am afraid that I stopped continuing in the middle of the research.
Although Chang Haonan probably has no chance to know how the technicians in the previous life finally solved this problem.
But fortunately, he now has his own way.
Moreover, the previous ideas of the Second Academy may not be without value...
“Different types of warheads have different specific characteristics. I can only say now that, in principle, Self-sweating materials can indeed directly reduce surface temperature, but if you want more specific data, it would be better to wait until we return to Beijing and then cooperate between the two project teams.”
Chang Haonan first gave a satisfactory response.
Dai Pengxin only had initial contact with Chang Haonan, so naturally he nodded repeatedly.
But before he could speak, the latter changed the topic:
"In addition, if you are sure to cooperate with us, it would be best if you can bring your previous research results on roll deceleration and variable center of mass maneuvers. Also join in.”
"Oh?"
This request was obviously beyond Dai Pengxin's expectation:
"Academician Chang, your research...also requires the use of variable center of mass maneuver technology?"
"For hypersonic weapons, the control torque provided by metamorphic core energy 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 biconical warheads, the interference torque experienced by the missile can be converted into a roll acceleration interference term and introduced into the autopilot closed loop. If it can be combined with slider control, it can be used to offset external interference. Item, improve the terminal hit accuracy."
After hearing this idea, Dai Pengxin thought for a moment, and seemed to have failed to follow Chang Haonan's flexible problem-solving ideas.
But the latter's explanation just now is quite general, so it is impossible to analyze it from it.
He had no choice but to convince himself and temporarily accepted this setting:
"Academician Chang, I will report to the superiors immediately after I get back..."
...
That's it. The 810th Brigade celebrated the successful launch and began collecting and analyzing full-range data. The results of the surface-to-air missile interception test have also been sent to a group of Air Force leaders who were meeting.
Obviously, the situation is not optimistic.
Without predicting the direction and time of the target's attack in advance, even the most basic shooting preparations could not be completed.
If it were under actual combat conditions, then the air defense position itself, or the important targets it protected, would most likely have been destroyed by this mere attack.
Although everyone has estimated the power of hypersonic weapons before, but simply thinking about it, it is impossible to be as intuitive as the results of the confrontation test in black and white.
After a long moment of silence, Qiao Chenqing adjusted his sitting posture, and then asked Sun Zhejun, the air affairs director next to him:
"This Commander Lu Zhicheng, I remember that he was there last year Target shooting in Suzhou, the one who successfully passed the acceptance test with seven out of seven shots?”
The latter nodded:
"Yes, but all the personnel in Suzhou were highly qualified, so Comrade Lu Zhicheng was actually responsible for commanding the missile launch company himself. He is the most experienced in the field of anti-missile interception in our army. One of the commanders..."
Hearing this, the expressions of the other people around the conference table changed slightly.
The most experienced commander in the army, equipped with the most advanced air defense system currently.
As a result, the stable tracking target cannot even 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 air defense level of important areas in key areas.
Especially after the test last year, which proved that the latest generation of air defense missiles are capable of resisting short- and medium-range tactical ballistic missiles, we breathed a sigh of relief after a long absence.
As a result, less than a year after the breath was released, it was tightening again.
“Comrade Lu Guang.”
Qiao Chenqing looked at the head of the Air Force Equipment Research Institute sitting at the end of the conference table:
"Do you think... can the latest air defense system we are developing effectively face such ultra-high-speed targets?"< br>
Lv Guang had actually guessed that he would be asked this question just now, but he still pretended to think deeply for a while to avoid appearing too frivolous:
“The basic Hongqi 9 was launched at the end of last year. Already handed in The current feedback is that except for the short range, other performances are roughly equivalent to or better than S300PMU2..."
"But the two systems are still essentially products of the same generation. Our research and development focus that year was also to strengthen the ability to deal with multi-frequency and ultra-low-altitude targets... If we face high-speed incoming ballistic targets, I am afraid there will be no essential difference in performance..."
His answer was quite tactful, but the meaning was not difficult to understand -
No.
Qiao Chenqing couldn't help but show a distressed expression:
"It seems that the new three-on-three defense is a bit outdated... We need to study the '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 in 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 defend the coastal cities, the air defense troops were forced to even pull out 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 pay attention to the enemy tactically. The technical strength of the Americans cannot be underestimated... Their research on hypersonic weapons should still be ahead of us. Front."
At this point, Qiao Chenqing paused slightly:
"Comrade Lu Guang, if we assume that the US military will equip hypersonic missiles like this in the next few years, and will It is defined as a tactical weapon, so what is a more reliable response? "
It should be said that from the point of view of 2005, his analysis is actually quite reasonable.
Although it is true that there are no models that have been equipped with the troops, the U.S. Army, Navy, Air Force and NASA have established their own hypersonic research institutions.
No matter how you look at it, it is a lively and prosperous scene.
And this time, Lu Guang’s answer was very quick:
“The only way is to develop an air defense system specifically for anti-missile like the United States and the Soviet Union did back then!”
