Chapter 555: This thing is still attack-5?

Fortunately, other comrades now do not know the equipment situation of Master 6, and this equipment situation is unlikely to reappear. At least Master 7’s imitation should be smoother.

To put it another way, we provided the materials and the Russians cooked the food and produced LYP-7 for us.

Again, a certain degree of falling out will not necessarily affect business.

Even so, Gao Zhendong's big step, which seemed to be bound to involve that kind of thing, still made everyone feel a little hard to accept.

But both the Air Force and the National Defense Committee have become more or less accustomed to Gao Zhendong's radical and terrifying style. They probably also know that there are always some reasons for his radicalism, at least these reasons are absolutely self-consistent in his own opinion.

Well, it’s not a big deal. Let me explain the terms first.

"First, let's talk about what battlefield interdiction means. In what specific aspects can a multi-purpose fighter jet be used?"

Gao Zhendong also knew that these things would most likely need to be explained, so he had already made preparations. He opened his notebook and explained several terms in front of the blackboard.

In order to distinguish between battlefield interdiction and close ground support, they even drew a picture.

The comrades in the Air Force listened attentively to what Gao Zhendong said, and talked about their feelings with a bit of emotion.

"No wonder I always felt that the mission and performance requirements of Gong-5 seemed strange. After all this time, they are two completely different things."

"Well, Chief Engineer Gao made a good classification. Battlefield interdiction and close support are both tactical attack missions, but the mission content, penetration requirements, and attack methods are completely different. The requirements for fighters are also completely different."

"Please write down what Chief Engineer Gao said. This is something worth further study."

"I've written it all down. I haven't even finished studying Chief Engineer Gao's speech last time."

"..."

At that time, our Air Force's research on tactics and strategies was relatively scarce, so we were very interested in what Gao Zhendong said. Regardless of whether it was right or not, at least it seemed that he had thought deeply about it and had a set of ideas.

This is already rare. Judging from Gao Zhendong's understanding and performance of equipment, techniques and tactics, his in-depth thinking is of great reference value.

The Air Force would not blindly follow Gao Zhendong's words as a guide, but it can still use them as a reference.

As for multi-purpose fighter jets, this is a brand new concept. Even the Americans did not have this concept at that time.

After hearing Gao Zhendong describe a new type of combat aircraft that could both conduct air defense operations and carry out penetration bombing, with its production and operating costs kept within a certain range, the Air Force found it somewhat unreal.

"This thing sounds good, but as we all know, jack of all trades often means slack in all trades. How can we guarantee that it can do all these things well? Especially under the premise of strictly controlling its costs."

There is no good thing at a cheap price, and the Air Force understands this principle.

Gao Zhendong listed the known air combat data and his recent statistical results on the blackboard before he began to explain his reasons.

"My starting point for these aspects is this. First, we have all seen that a large number of air battles will occur at medium and low altitudes. High altitude is a specialized battlefield, mainly based on interception operations, whether it is high-to-high interception or high-to-low interception. However, at high altitudes, due to the problem of oxygen content, it is highly likely that a fight will not be possible."

The comrades in the Air Force thought about how difficult it was to fight the U-2 at an altitude of 2 meters. Well, there really were no major maneuvers that could be made. If they made any major movements, not to mention hitting the enemy, they would fall down first.

Around 1 is better, but not much better.

Well, that seems to be the case.

After talking about high altitude, Gao Zhendong talked about high speed: "Due to the existence of the sound barrier, supersonic speed is mostly used for approaching the enemy. As for supersonic air combat and dogfighting, it will not be a realistic possibility for a long time. At the same time, the main speed range for air combat is still subsonic and high subsonic."

No need to think too much, everyone has a deep understanding of this. There is no maneuverability at supersonic speed. If the movements are too big, it will be worse than at high altitude. At high altitude, you will fall down and there is still a chance to recover. If the supersonic maneuver is too big, the plane may fall apart.

Well, that makes sense. "So I personally think that as a cheap multi-purpose fighter, its high-altitude and high-speed performance can be abandoned, or not given priority, and instead efforts should be made on medium- and low-altitude flight performance, subsonic and high-subsonic maneuverability, lift-to-drag ratio, and mounting capacity, and various parameters within this envelope should be optimized."

Since it is impossible to cover everything, it is better to focus on the combat airspace where the probability of air combat is the highest. There seems to be nothing wrong with this idea.

Oh no, it feels like I’m trapped in it and can’t get out!
In fact, after all, Gao Zhendong's argument is mainly based on the actual development route of fighter jets in previous lives. Both his arguments and evidence are ready-made and quite persuasive.

Although the air force comrades are still not very clear in theory, they are very clear about the equipment situation: "But even so, it still cannot solve the problem of the combat effectiveness and multi-purpose of cheap fighters. In fact, the Z-6 is now in this state, but its combat effectiveness can only be said to be sufficient, let alone multi-purpose."

Gao Zhendong smiled and said, "So, I would like to suggest using the Attack-5 combat model as a multi-purpose fighter. It has a major advantage, the air intakes on both sides can leave space in the nose for the radar."

Radar again.

"Don't underestimate this thing. With a good radar and decent semi-active radar air-to-air missiles, fighters can attack enemy aircraft from 20-30 kilometers away, destroy the enemy aircraft's posture, and then seize the initiative in air combat. Combined with optimized medium-low altitude, high-pressure supersonic maneuverability, and infrared-guided air-to-air combat missiles, its air combat capability cannot be underestimated."

For a moment, everyone was attracted by the beautiful blueprint painted by Gao Zhendong and temporarily forgot to cause trouble for him. Gao Zhendong struck while the iron was hot.

"At the same time, a good radar can track terrain, enhance the fighter's penetration capability when striking the ground and sea, and also make the ammunition carried by the fighter more accurate. In this case, as long as there is a decent range and a decent ammunition load, the ground strike capability of this fighter will not be too bad."

As they listened, the comrades in the Air Force came to their senses.

"That's not right. How can this thing be so cheap if it has radar installed?"

Gao Zhendong smiled and said, "Given its size, it cannot be equipped with a particularly large radar. Compared with larger fighters, it is still cheaper when equipped with the same level of equipment. Besides, even if it is not equipped with a radar, the various sights installed on the nose are still an advantage over the Zhan-6."

I have learned the theory of relativity very well. At this time, we cannot discuss absolute prices, but only relative prices.

But the Air Force was afraid that they didn't have a radar. If they had a suitable radar, would they be willing to leave the nose of the aircraft empty? Gao Zhendong was the first to disbelieve it.

Sure enough, the comrades in the Air Force thought about it and it seemed to be true. The smaller one is cheaper than the bigger one. You can't want the horse to run without eating grass. So the radar must be installed.

"But as far as we know, the height and speed of the Gong-5 are much worse than the already not-so-excellent Zhan-6. It does not meet our minimum requirements for fighter jets. I'm afraid it won't work to replace the Zhan-6 with it."

Upon hearing this, Gao Zhendong looked as if he had been prepared and was confident. He took out several sets of information and handed them to the confidential personnel of the meeting, asking them to distribute them to several important comrades.

"Dear leaders, this document is the result of extensive communication between me and the comrades from the China Aviation Industry Corporation. The comrades from the China Aviation Industry Corporation evaluated the main parameters of the combat version of the Gong-6 based on the latest LYP-5 engine of the Northeast Aerospace Development Institute and combined with the aerodynamic and structural improvements we agreed on. Please take a look at it first."

When the leaders of the Defense Work Committee saw this, they knew that Mr. Xiao from the Cifei Factory had been busy in Beijing recently, and it turned out that he was doing something with Gao Zhendong.

Gao Zhendong really never fights a battle without preparation, especially a big one like this!
He, the chief engineer of the Defense Work Committee, and the main comrades of the Air Force took the information distributed by Gao Zhendong. The more they read, the more frightened they became, and their facial expressions changed.

What magic medicine did Gao Zhendong give to the China Aviation Industry Corporation? This aircraft looks very much improved. If you say that these improvements were made by the China Aviation Industry Corporation itself, no one would believe it. If it could be done, it would have been done long ago, not until now.

"Is this thing still Attack-5? Are the parameters in this material scientifically estimated?"

Gao Zhendong was well prepared: "This is an estimate made by our colleagues at the China Aviation Industry Corporation based on existing theories and experience. At the same time, our colleagues at the China Aviation Industry Corporation also made a model at the fastest speed and blew it through a transonic wind tunnel. The results were quite good. The evaluation of these parameters also referred to the wind tunnel test results."

The people from the Defense Work Committee looked at Gao Zhendong and secretly sighed that Gao Zhendong and the Cifei Factory were moving too fast. It had not been long since the wind tunnel was blown once.

However, with the support of wind tunnel tests, the credibility of these estimated parameters is higher.

It's not that they don't trust Gao Zhendong and the Cifei Factory, but the overall improvement of the data in their hands is astonishingly large. Their first feeling is not that Gao and Xiao are lying, and these two comrades can't afford to lose face, but they feel that they have calculated wrong!
The internal fuel range has been increased by 1%, and the speed and altitude have caught up with the original MiG-19, and the altitude is even slightly higher. The maximum bomb load has increased by 30% to 2 tons, and this 2 tons is achieved under the premise of taking into account the increased weight of avionics systems such as radar.

It's no wonder they were surprised. Gao Zhendong himself was surprised when he saw the data. At least he originally didn't expect that the speed could catch up with the MiG-19. The speed advantage of the nose air intake is difficult to offset.
