Chapter 556 Air Force: I want them all!
For this, Mr. Xiao said there was nothing he could do. The LYP-6 made of 591 and tungsten-molybdenum alloy was too much. At the same time, the Northeast Aviation Research Institute, which no longer cares about material performance, even has enough energy to solve the surge problem caused by unstable combustion in the original MiG-19 engine.
The afterburner thrust increased sharply from 31.5 kN to 40 kN, and the military thrust also increased accordingly. The changes brought by this are really too great.
Coupled with some benefits brought by improvements such as wing-body fusion, bomb-to-oil modification, and side-strip wings, the performance of the Attack-5 has been completely transformed.
Even the leading edge serrations achieve a larger wing volume without basically changing the weight of the aircraft.
This is still a conservative estimate. It has not yet entered into detailed design. There is still potential to be tapped.
However, both Gao Zhendong and Mr. Xiao know very well the principle of leaving room for action. When reporting good news on forward-looking matters, it is best to prepare an ambush.
Several comrades who were the first to get the evaluation data distributed the materials for everyone attending the meeting to see, otherwise it would not be easy to discuss. This matter is a bit big, even if it is an intentional opinion, it will not be discussed. We need to fully learn from everyone’s experience.
Like the previous comrades, when everyone got this data, their first reaction was disbelief, and then surprise.
“Isn’t this impossible? So much improvement all at once?”
"Wrong calculation?"
"They probably won't. There are only a few ways to go back and forth in this kind of estimation, and there are traces to follow."
"Those who have blown through the wind tunnel, There may be differences in the details, but there shouldn’t be much of a problem in the general direction.”
“Then this is amazing!”
“If it can basically achieve this performance, then this aircraft will replace it. It’s possible to fight -6.”
"..."
Some comrades also responded quickly. There is a problem here.
"Chief Engineer Gao, can the improvements that can be used on the Attack-5 also be used on the Zhan-6? With these improvements, can the Zhan-6 achieve higher flight performance?"
Gao Zhendong nodded: "Part of the improvements can indeed be applied to the Zhan-6, and the flight performance can be further improved. But the most important improvement for multi-purpose purposes - the electronic equipment space on the nose, the Zhan-6 -6 cannot be changed no matter what. This is a matter of innate trade-offs."
After Gao Zhendong finished speaking, he made an estimate: "Please see, if other conditions remain unchanged, for The most important thrust for speed is an increase of about 27%. According to the formula, speed is positively related to the square root of thrust. In other words, a simple calculation shows that under this thrust, the speed can be increased by about 12%, and ultimately it will be about Mach 1.5. ”
Well, data is the easiest to compare. Although Gao Zhendong's estimate is very simple, it is well organized.
Seeing that everyone agreed with his calculation, Gao Zhendong continued: "Even if the increase is calculated based on attack -5 plus other improvements, it can only increase to Mach 1.6. This is not the same as attack There is no essential difference between the 1.35 and the estimated 1.35 from -5. Don’t forget that there is a price.”
The Air Force’s eyes lit up just now at Mach 1.6, but they quickly remembered something. Excited.
But other comrades don’t know what they are thinking, they just want to know, then, what is the price?
“I won’t go into details about the radar issues. It should be noted that even with these improvements, the internal fuel range and bomb load of the Zhan-6 are still not as good as the Attack-5.”
Some comrades expressed confusion about this: "Why? There is not much difference in the structure of the two, right?"
"There is still a difference. Originally, the Attack-5 was improved to be an attack aircraft. The bomb bay and larger wing load make its speed so much lower than that of the Z-6 under the same conditions. In addition to the resistance caused by the nose air intake, part of it is the price paid for these improvements. But these costs are not in vain. Yes, when the G-5 is used as a multi-purpose fighter, these benefits still exist. "
The bomb load of the Zhan-6, after deducting the auxiliary fuel tank, is 0.5 tons, while the original G-5 type. , is 1.5 tons!
To put it bluntly, the Porcelain Aircraft Factory has given the Gong-5 a better fuselage structure design based on the Zhan-6. Whether it is an attack aircraft or a fighter, in addition to speed, it has a better foundation. .
But does speed matter? Not too important here.
"The speed gained by paying so much price is not of much use in actual air combat. It can only be reached by using afterburner. Whether it is 1.35 or 1.6, there is actually not much difference. The real Air combat will not occur in this speed range."
But speed is not completely useless. Other comrades know very well: "But what about volleys?"
Gao Zhendong smiled a little. Mysterious: "The problem of interception is the mission of another type of three-level aircraft, and this Mach 1.6 Z-6 can be used as a backup for that type. If the target aircraft of that type cannot be achieved, use this high-speed fighter -6 as an interceptor. "Gao Zhendong actually knew it well. The situation he saw in his previous life was much more severe than the current situation. In his previous life, even using the Mach 1.6 Z-6 as an interceptor was a luxury. As for Master 7... he changed it to the end. It is also a good plane, but the problem is that it comes too late. The saying that you are not afraid of being late for a good meal does not apply to military equipment.
Of course, getting rich is not counted as Mr. 7. This thing is already new.
And he smiled mysteriously, but he was actually laughing at the Air Force. Please tell me, don't you have any idea whether this thing is the most suitable for volleys?
Actually, not only the Air Force knows about it, but a very small number of comrades here also know about it, but they dare not say anything.
The comrade in the Air Force coughed twice and said with a little embarrassment: "Ahem, what, we are negotiating with Lao Maozi about the introduction of imitation MiG-21. That aircraft flies faster than this one. , Flying high.”
The comrades at the meeting suddenly realized, hey, if you had told me earlier, if there were better interceptors, then there would be no need for the Zhan-6 to take on the interception mission.
Also, Chief Engineer Gao’s idea of using the high-speed Zhan-6 as a backup model of the interceptor is also very good, and it effectively reduces the overall risk of the interceptor.
Originally, the introduction and imitation of the MiG-21 started in March 1961. Although this matter was a secret, the people at this meeting were all qualified to know about it. There is no point in continuing to cover it up, and it will affect the intention. judgment.
This aircraft's speed of Mach 2.05 and practical ceiling of 18,700 meters are more suitable for interception. Although the combat radius of 600 kilometers is smaller, there is no essential difference between Master 6's 680 kilometers. Besides, Yes, it’s not like it can’t be changed. The Air Force is becoming more and more interested and confident in the improvement of aircraft.
In the end, the National Defense Work Committee considered something more practical: "But if there is such a big change, the supporting facilities of the production plant will also be a problem. Now the entire system has been established for the Zhan-6. It is not that It can be changed by changing it.”
Gao Zhendong smiled happily: “Yes, that’s why I chose the G-5 as a multi-purpose fighter. It’s the same parent as the Z-6. They are twin brothers, and they must also be biological brothers. The production supporting system prepared for Zhan-6 does not cost much for it, and it can be used after modification. "
And in this way, Zhan-6 can be used. People related to the -6 system will have less resistance to this matter, because they will still do whatever they should do without being affected.
The National Defense Work Committee and the Air Force were speechless for a moment. Hey, this guy is waiting here. He has thought very carefully from beginning to end, and everything is buttoned tightly and perfectly.
But looking back, a plane has a combat radius of more than 800 kilometers, a top speed of Mach 1.35, a practical ceiling of 17,600 meters, and a bomb load of 2 tons. It has low-altitude and high-speed penetration capabilities, and a big head can hold more Electronic equipment, but also a relatively cheap multi-role fighter jet, don't you?
Don’t be a fool!
Even if the data in hand is estimated and has not yet been realized, the evaluation process is scientific and the basis of the evaluation has even been researched. If the data is not made up, then it is worth it. Dig deeper.
The leader of the Air Force pondered for a long time and nodded: "Well, in my personal opinion, this thing is worth doing, but now the Zhan-6 does not need to be produced at low speed, but is produced normally, just like this A high-altitude and high-speed type with the latest engine, or an interception type, will be produced. In this way, before the new system is formed, there will be more useful interceptor fighters, and the production of this Z-6 interception type will not be wasted. Until the MiG-21 is successfully copied.”
They have to be generous. As long as there is something good, they will try their best to get it.
The High Speed War-6 cannot be left alone, as it will affect the homeland air defense combat capabilities. Good aircraft must also be built without delaying both sides.
The Zhan-6 interception type and the Attack-5 combat type are all needed. The Air Force has many issues to consider. Unlike Gao Zhendong, he only considers saving money as much as possible on the basis of ensuring the effect.
On this matter, the Air Force is a conservative, but they feel that Gao Zhendong, a radical, is still too conservative.
Gao Zhendong can only sigh that they are better at this aspect.
What he didn't notice was that comrades in the Air Force had begun to use the "new system" to generally refer to the G-5 combat type. What this meant was self-evident.
Everyone felt that this decision was reliable, even the comrades related to Zhan-6, they were not affected at all.
Continue normal production of the Z-6 interceptor type, and after the Attack-5 combat type is completed, the two will be produced in parallel until the MiG-21 imitation is completed, and the production of the Attack-5 combat type will be fully converted without any delay. No one will get hurt.
That's not entirely true - the enemy will be injured.
This is also what comrades of the Air Force consider on another level besides technology and tactics. This approach not only reduces technical risks to a minimum, but also ensures the homeland air defense combat capabilities to the maximum extent without affecting any People, there is very little resistance to implementation.
It can be said that this proposal from the Air Force truly considers the multi-role fighter as something that needs to be implemented effectively, so it tries to take care of all parties and reduce all kinds of resistance.
