Chapter 517 Go back and make a new one
“The radar-guided air-to-air missile can rely on the aircraft itself as a platform to provide a longer search and detection distance, as well as a longer guidance distance. Of course, it is very useful for the carrier aircraft. There are certain requirements in itself. We will ignore this matter for now and only discuss the capabilities that the radar-guided air-to-air missile itself may obtain. "
The reason why Gao Zhendong said this is because it is now and even foreseeable for a certain period of time. Within, the fighter jets we can obtain all have nose air intakes, which makes radar-guided air-to-air missiles inherently deficient.
But now, no one is aware of this problem, but after listening to Gao Zhendong's judgment on radar air-to-air bombs, they feel that it makes sense.
"Well, give infrared bombs within 10 kilometers, and radar bombs beyond 10 kilometers. This division is very clear, and it seems to bring a lot of benefits."
"Yes, yes, in this way, the radar missile can ignore combat matters, give up some of its needs, and put the limited missile resources into matters 10 kilometers away."
" What exactly needs to be done 10 kilometers away?”
“Uh... Listen to Mr. Gao, I haven’t thought about it yet.”
Waiting for everyone to discuss it. After a while, Gao Zhendong spoke: "In my opinion, radar air-to-air bombs mainly take advantage of the detection range of airborne radar to attack the enemy from medium and long distances. They play an interception role for low-mobility targets, and they play a role in intercepting high-mobility targets. The maneuvering target at least has the effect of interfering with its flight posture and destroying its engagement status. "
At the beginning, when the performance of radar bombs was relatively average, this was how BVR operations were performed. The performance of radar air-to-air bombs was similar. It does not guarantee a large enough no-escape zone, but it still has tactical significance.
In Gao Zhendong's view, given the current technical environment, even if radar air-to-air bombs are developed, it is impossible to reach the level of the 21st century. Therefore, the current tactical target of radar's medium-range air-to-air bombs still cannot be expected to be killed in one hit. It should be incorporated into the entire air combat system.
“Therefore, the important thing about radar air-to-air bombs is that they can see far and fly far. They are not as maneuverable as infrared fighting bombs. The high-mobility design of fighting bombs can be basically thrown away to improve the range. . ”
These words give everyone some space to think about changing the mission positioning of radar bombs. Instead of being greedy for perfection, only completing the most important mission can indeed make it possible. The development of radar air-to-air bombs is smoother.
Many times, the most taboo thing in doing things is greed, especially when doing applied research, if you want everything, you often can’t get anything done.
The comrades in the Air Force understood Gao Zhendong’s statement quite quickly. After all, this is what they do.
"Mr. Gao, do you mean to use radar air-to-air bombs to create conditions for close combat starting from medium and long range? The main purpose of mid- and long-range strikes is to destroy their status. As for whether they can be shot down, is it a single shot?" ”
When I first heard about this idea of not seeking to shoot down, I felt very outrageous. Where can there be an air-to-air missile that does not seek to shoot down enemy aircraft as its main requirement?
Gao Zhendong nodded: "Yes, to ensure that we can shoot down enemy aircraft with a high probability at medium and long distances, especially high-mobility targets such as fighter jets, the cost is very high and the technical requirements are very high, so we might as well take a step back and just Just ensure that there is a high probability of shooting down bombers, transport planes, and reconnaissance aircraft that are not very maneuverable.”
This is actually quite embarrassing to say. The K-5 just killed was a hit. It is not far away and cannot be defeated. In fact, Gao Zhendong's request to "take a step back" is an impossible task for K-5.
Are you taking a step back? You've obviously taken a lot of steps forward!
However, Gao Zhendong clearly proposed that the requirements for attacking high-mobility targets with medium- and long-range air-to-air missiles should be reduced to harassment. This is indeed a downgrade of tactical requirements.
The tactical requirements and actual performance of equipment are actually incompatible. The reason is very simple. The requirements are high, but if they cannot be made, they have to make do.
After thinking about it carefully, the comrades who participated in the meeting felt that Gao Zhendong’s idea was very clear. If it can’t be done, just abandon it and clearly lower the requirements, so that there is no need to worry about those who can’t achieve it in the design. Spending time and paying the price to achieve your goals will not affect the achievement of your main goals.
The leader of the National Defense Working Committee smiled and said: "Take a step back and the sky is brighter. Well, it makes sense. Zhendong, the thinking is very clear."
The comrades of the Air Force raised their own questions: "But there is one The problem is that the enemy aircraft can get rid of mid-range air-to-air bombs by performing large overload maneuvers. After that, it can quickly resume its engagement posture."
Gao Zhendong smiled and shook his head: "Not necessarily, at least the height is difficult to recover in a short time."
The comrades in the Air Force's eyes lit up and fell into thinking, but other comrades were confused. Height, isn't it? Is it okay to just fly up, and what does the large overload maneuver in the air have to do with altitude?
Seeing the puzzled expressions on others' faces, Gao Zhendong explained: "Even a fighter jet relies on the lift obtained from movement to maintain altitude. As long as its thrust-to-weight ratio does not exceed 1, any aircraft can achieve maximum overload. The best way to maneuver is to fly down, not up, because flying down can use the gravitational potential energy. Even if you barely move up, a large overload maneuver will lose a lot of energy. This is fighting. The comrades in the Air Force can confirm this situation."
The comrades in the Air Force have roughly figured it out and happily accepted Gao Zhendong's words: "That's right! Without energy in the air, it is difficult to make combat moves! In the range of 10 to 30 kilometers, fighter engagement time is very fast. Once the engagement posture is destroyed, it is difficult to recover in a short time.”
This is another forward-looking article on tactics and tactics! No, no, no, Chief Engineer Gao really gave me too much, and I can’t digest it. Comrades from the Institute of Guidance and Research have a good understanding of the specific performance of the missile and have their own opinions: "Mr. Gao, the current radar air-to-air missile cannot support this head-on strike mode."
“It is true that the K-5 cannot fight head-on, but we are no longer discussing the K-5. We no longer use the K-5 method. This problem can be solved with semi-active continuous wave radar, using The aircraft-mounted radar provides target illumination for the missile, and it is possible to hit it head-on. "
"This seems to be no different from the K-5?" In the eyes of some comrades, isn't this the aircraft-mounted radar that provides guidance? Well.
“The difference is very big. Semi-active continuous wave receives the reflection echo of the radar wave of the carrier aircraft on the target. The requirements for the motion relationship between the carrier aircraft, the target, and the air-to-air bomb itself are much better than The radar beam of the K-5 is much lower. "
In principle, it is easy to understand. As soon as the window paper is pierced, most comrades will react. That's the truth.
The comrade in the Air Force looked at the records in his notebook and said to Gao Zhendong: "General Engineer Gao, your idea is to build a semi-active continuous wave guided missile with a maximum range of 20 to 30 kilometers?"
Gao Zhendong nodded: "Yes, I have thought about it. In terms of the range of the missile itself, after increasing the missile body, basically this range can be satisfied. The problem is not big, so the core range of the missile itself can be solved. The biggest problem is the radar. "
"Radar?" Some of us didn't get around the corner. None of us were involved in aircraft operations. Even the air force comrades who were using the aircraft couldn't think of the nose of the aircraft. The relationship between space and radar.
Gao Zhendong nodded: "Yes, radar. Our fighter jets all have nose air intakes. Such a structure is good for high speed, but it will seriously affect the layout of the radar. This is what we The biggest obstacle in researching radar air-to-air bombs. "
Everyone knows that big is good. Thinking about the nose space of Zhan-5 and Zhan-6, everyone shook their heads inwardly.
Only the leaders of the National Defense Work Committee and the comrades of the Air Force did not look downcast, but their eyes flashed, as if they were thinking about something.
Seeing that everyone looked a little solemn, it was impossible for Gao Zhendong to change the equipment of the existing fighter jets and the research and development plan within a certain period of time. He could only start from other places. He was going to play an evil way. , at least give everyone the confidence to take down the radar bomb.
“However, it’s not impossible.”
Huh? Comrades from the National Defense Working Committee and the Air Force who had some ideas all looked at him. Comrade Gao Zhendong was indeed so reliable. He could come up with a plan as soon as he raised a problem.
Those who can only ask questions will definitely not be as popular as those who can also come up with solutions. Just like reporting a problem to a leader, it is best to bring your own solution. Even if the solution is unreliable, it is better than just asking questions.
"What plan? Tell me." The leader of the Defense Working Committee was very interested. He believed that Gao Zhendong didn't know what they knew, so he was very curious about what other ways Gao Zhendong could find.
“Have the Tu-4s been modified a few times, and now the enemy doesn’t dare to come at all?”
Everyone suddenly realized that there is not enough space in the nose, right? Find a plane with enough headroom!
"Hey, this is a good idea. The enemy's P-2V is scared of being beaten, and the Tu-4 is idle now. It seems okay to use it to do this first."
"No. Maybe? The Tu-4 has that kind of maneuverability and speed, so it doesn’t have the ability to participate in air combat.”
"It doesn't have to be to participate in air combat. No matter when attacking or defending, it is still possible to keep up through formation arrangements and route coordination. Didn't you hear Chief Engineer Gao say that this thing is not responsible for fighting, it is just harassment. It only needs to be left alone. Just shoot the missile out for dozens of kilometers and then sling it at a low speed to illuminate it.”
In fact, this method is unreliable. Before the phased array, the number of missiles that semi-active radar could guide at the same time was Extremely limited, but Gao Zhendong's ultimate goal is not only this, so he just happily watched his comrades open their imaginations.
But no matter what, one thing is for sure. Using the Tu-4 Special can at least support the research on semi-active radar medium-range air-to-air bombs. This thing cannot be developed in a short time. In the future Things, who knows.
