Siheyuan: I eat melons while doing scientific research

Chapter 1171 Selling it for the sake of happiness

It has to be Commissioner Gao. When he is the deputy chief engineer, it is really useful!
By developing a small indicator, you can solve important needs in practical applications.

Although everyone understood, Gao Zhendong still explained it.

"Yes, that's what I mean. The comrade from the missile research institute just mentioned that the missile has a limited chance of hitting high-maneuvering targets in the second half of its range. This is an objective fact. Of course, there is a solution, but this objective fact does exist, so we calculated it. Everyone can understand the meaning of "no escape", which means that even highly maneuverable aircraft cannot escape within this range."

The comrades nodded one after another, but the comrades from the Air Force and the Institute of Missile Research only heard one sentence, "It's not that there is no solution."

There are many people talking about this now, so we won’t discuss this matter for now, but the Air Equipment Bureau and the Research Institute are really itching to do so.

Now they understand what "curiosity kills the cat" means.

Moreover, this matter is not just a matter of curiosity, but something that is of great use, not to mention the discomfort I feel in my heart.

Fortunately, they are still rational, and Commissioner Gao will not run away, so there is nothing to be afraid of.

"So what is high mobility? Should we give a definition?" said a comrade from the Institute of Guidance and Research. If we don't give a definition, we can't calculate or measure it.

Before Gao Zhendong could say anything, a comrade from the Air Force took over the conversation: "Comrade Zhendong, you don't need to answer this question. Let me tell you. 9G, for shooting down an aircraft, an overload of 9G is considered a high-mobility target, because this is the limit of the overload that the human body can withstand. If it goes higher, there is no need to shoot, the aircraft will fall down by itself."

9G is the limit of overload that people who have undergone rigorous training can withstand. Of course, there may be supermen who can reach 9.1 or 9.2, but it is meaningless. As for universal laws, this is the case.

The Air Force is the most familiar with this matter. They directly set the maximum requirements. However, due to the human factor, this requirement is actually not harsh for missiles to shoot it down.

Gao Zhendong nodded and added, "Yes, that's right. As for how to calculate this no-escape zone, the simplest way is to draw the dynamic range fan of the missile after launch. In this area, it is difficult for a powered missile to escape even for a fighter jet..."

Where there is power, there is energy for maneuvering. In any case, even the medium-range missiles with relatively poor maneuverability among air-to-air missiles cannot be compared with the maneuverability of an aircraft equipped with wetware.

"What about the complicated method?" Knowing that Gao Zhendong always had multiple plans for the same thing, and they were progressive from low to high, the comrades in the Institute of Guidance and Research were also very interested in the "complicated" method.

"If it's not simple, then it has to be calculated and tested based on the missile's energy, status, combat altitude and other conditions at the time. However, this distance is not much farther than the powered range. If you are in a hurry to use it for the fire control system, you can just use the powered range instead. It will definitely be usable." Gao Zhendong said.

The comrade from the Air Force nodded and said, "Yes, we want the dynamic range, which is safe. We just need to know which range is the safest and give a prompt in the fire control system."

The calculations are too complicated and still cause some trouble for the current airborne fire control radar computers. Having a reliable prompt is enough for the Air Force.

The chief designer of the model laughed and said, "Then I can give you an approximate no-escape distance now. Of course, it's only in front of us. We need to calculate the left and right sectors carefully. The no-escape distance in front of us is about less than 20 kilometers. The maximum speed of this missile is Mach 4, which is about 1.3 kilometers per second. Without considering the altitude and other conditions, if we don't calculate it rigorously, the distance from the start of acceleration to the end of the engine burning out is this."

It seems that this engine takes a long time to accelerate, Gao Zhendong thought. But this is not a big problem.

But for the comrades in the Air Force, this is simply a great joy.

20 kilometers? This is equal to the lower limit of the planned range. Although we know that "no escape" is just a description and it is not actually a 100% hit rate, it at least shows that within a range of 20 kilometers, the possibility of enemy aircraft escaping is very small.

"Okay! Let's calculate it this way, and then we can build the no-escape zone into the fighter jet's fire control system."

It is rather troublesome for people to calculate the no-escape zone based on distance, direction and speed in air combat, but for computers, this calculation is relatively simple, and it is even simpler for the military reinforced version of C6132.

"Well, we can only provide data. As for implementing this into the aircraft, it has to be done by fighter research units. We can't do their fire control system either." The chief designer of the Thunder-2 model said with a smile.

Oh, I forgot, the Air Force comrade slapped his head and laughed at himself.

The report is still going on. In general, this is a medium-range radar-guided air-to-air missile with a range of 45 kilometers and a combat altitude of 20 kilometers.

Moreover, it has an extremely high kill probability in the no-escape zone. At the maximum range, it also has a relatively high kill probability for non-high-maneuverable targets such as bombers and transport aircraft.

The Air Force was very satisfied with this thing, especially after seeing the performance of the AIM-7C/D of the United States, they felt "never expected it". We are so much ahead of the United States all of a sudden?
They got many versions of AIM-7C/D with a range of 24 kilometers. Compared with the 2-kilometer range of the Thunder-45, our comrades felt it was unreal.

This, this, this... I originally thought that the planned upper range limit of 30 kilometers was a bit fantastic, like a toad wanting to eat swan meat, but when I got it, I didn't expect that it would turn out to be a phoenix!

Let's take a look at the long-range air-to-air missile R-63 that the Russians just put into production in 4, with a range of 20 kilometers...

My medium-range semi-active air-to-air missile R-8 at this time has a range of 12 kilometers...

The comrades in the Air Force even doubted whether there was something wrong with the data we obtained. Were the Russian missiles a little too weak? Or was the concept of our medium-range missiles different from that of the Russians?
What they don't know is that there are two reasons why the Russian missiles are so weak. The propellant and electronic system are one thing. The Russian 12-kilometer R-8 weighs 230 kg to 270 kg, which shows how weak these two are.

On the other hand, there is radar.

Compared with radars of the same generation and level, the Russian radars have never been better and their performance is always far inferior. This has never changed since the emergence of radar until the end of the Russian history.

Speaking of this, we will have something to say decades later.

But now it is the 60s, but Gao Zhendong dares to say with confidence that not to mention you Russians, even the Citibank guys will have to call us big brother for the time being.

But all this was unknown to the comrades in the Air Equipment Bureau and the Defense Work Committee, and they were still a little worried. But it doesn't matter if you worry, as the old saying goes, whether it's a mule or a horse, just take it out for a walk.

Today's venue is actually still at the missile research institute shooting range in the suburbs of Beijing, which is also the garrison base.

The Institute of Navigation and Research has prepared a lot of balloons with tin foil on the surface, waiting for this moment. They dare not to tow the target, because at such a long distance, hitting the towed target would pose too great a threat to the towing aircraft.

The report is finished, and everything that needs to be said and commented on has been said. The next thing will be easy. Pull him out and fight!

If you miss, then everything I said just now is useless. If you hit, then even if I didn’t say anything just now, it can be said that it speaks for itself.

The balloons took off one after another, and from 45 kilometers away, a Zhan-7 specially modified with the pulse PD radar under development began to attack.

The only fighter jet that can be equipped with pulse PD radar is the Z-7. This Z-7 has a heavy mission. It is the only one that has been modified with PD radar. Today, it has to fire 10 rounds in total. Theoretically, it can carry 10 rounds, but considering the range and safety issues, it can only carry 6 rounds. It will take two flights to complete the firing.

But the pilot in charge of the test was extremely excited. He had launched this missile more than once. During the development process, he cooperated with the Missile Research Institute to launch it many times. As one of the few pilots who had launched this missile, he knew very well that this missile was a good one!

With it, our sky will completely become a forbidden zone for the enemy!

Before this, who would have thought that they could defeat the enemy from 4 or 50 kilometers away? I dare not even think about it!
As the balloons were launched one by one in two batches at an altitude of thousands of meters, most of the missiles attacking from afar accurately blew up the balloons in the air, and the comrades were completely relieved.

10 out of 8 shots!
Comrades, this is true! We really have medium-range air-to-air missiles that can hit 45 kilometers!
Russian: You said "medium range" again?
However, our Air Force does classify this as medium range. The basis for this is exactly what Gao Zhendong proposed: only those above 70 kilometers are considered long range.

Compared to the extremely smooth reporting process with basically no questioning except for discussion, this target shooting actually took longer time. This was mainly because there was only one plane, and the balloons had to be released again after each shooting, and the plane had to enter the attack route again. Moreover, if the ammunition was used up in the middle, it had to be reloaded. The shooting lasted from morning to afternoon and took 5 hours.

The comrades showed no impatience at all and waited patiently for the experiment to be over.

While waiting for the plane to load bombs during the target shooting test, Gao Zhendong even talked with the chief engineer of the Defense Work Committee about the future of this thing.

"…This thing can be sold to the Russians…" During the internal discussion, Gao Zhendong was not vague.

The chief engineer and the air force comrades were a little surprised: "You're selling this too? Aren't you afraid of leaks?"

This is not Gao Zhendong's style.
