"This idea is very good, but technically speaking, it is completely impossible to do, the engine thrust of the single-engine fighter and the size of the aircraft seriously limit the aircraft to increase the range, if the range of the single-engine aircraft can be very long, there will be no twin-engine fighters in this world."

The soldier spoke very directly, and directly pointed out that it would definitely not work to make up an idea on the basis of the Jian-7, and at this time it could only be redeveloped.

The aircraft can only be redeveloped, and the issue of research and development funds must also be considered, and the military expenditure of the republic in these years is definitely quite tight.

"Since it is going to be re-developed, we will learn from the experience of the J-74 and J-75, and the two projects will first be combined for preliminary development, and finally develop their own models according to the respective needs of the Navy and Air Force, so as to maximize the use of all resources."

This is very tempting to say, and it has also won the recognition of the Navy and the Air Force, and if there are projects that have gone through this road and shown that this road can be taken, then it is definitely necessary to make use of these advanced experiences!

To this end, the Navy and Air Force are once again sitting together and preparing to work together to develop a new generation of twin-engine fighter projects.

……

The top level of the Central Military Commission agreed to start the project of a new generation of twin-engine fighters, but when it comes to the specific performance requirements of the fighters in the future, it needs to be jointly agreed upon by the Navy and Air Force and the Science and Technology Commission.

Before leaving the imperial capital, Wu Lao only heard the news mentioned earlier, and at most, the navy revealed a little bit of the navy's thoughts on the power system of the new generation of fighters.

This is why Wu Lao now took the opportunity to inform Yang Hui of the news, but because Wu Lao had left the imperial capital for a while, and had experienced the review of the turbofan 10A and the new Zhongtui core machine, it can be said that his news was already a little behind.

Speaking of the various actions of the Navy and Air Force after Wu Lao left the imperial capital, due to the operational requirements and environment in the two armies, the starting point of the foothold was different. From the very beginning, the joint project appeared to be full of gunsmoke.

The air force has always been the main force of the air force of the republic, and although the naval air force has made a beautiful comeback this time, the air force is still the first to speak when discussing the new technical and tactical indicators.

"The development of an aircraft must first look at the choice of power system, our Air Force believes that the power system of the new aircraft should use two high-thrust turbofan engines, and the new aircraft must reach the same level as the F15."

Boy. The Air Force's heart is not small, and as soon as it comes, it directly asks for a heavy fighter, which is indeed far-sighted.

If Yang Hui heard the words of the Air Force, he would definitely not be surprised, thinking about the last Air Force, didn't he even look at the MiG-29 with a double push, and the Su-27 with a double push was named by name.

From this point of view, the air force is addicted to heavy aircraft, of course, this is not wrong, the vast territory of the Republic does need heavy aircraft with a long endurance.

However, the Navy is not very optimistic about the power system of the new aircraft. Do you want to say that double big push is good?

For this problem, both the navy and the air force will say that it is good, but you have to be able to develop good things, and with the current technical level of the republic, it is still a little troublesome to develop a high-thrust turbofan engine.

The Navy has experienced the tragedy of seven dismounts and knows the importance of risk control in the development of a fighter. Therefore, although it is very drooling over the double push proposed by the Air Force, it has to be hindered by reality......

"The dual push-turbofan power system is not reliable. We don't have a finalized high-thrust turbofan engine right now, and the engine hasn't been put in place. Aircraft development is a castle in the air. ”

The Navy bluntly pointed out that the plan proposed by the Air Force was unrealistic and utopian, and then came up with a plan that the Navy considered reliable.

The navy's plan is definitely not a castle in the air, but some strong backing to support it, and it seems quite confident when it speaks.

I took out the information about the turbofan 10A engine sent back to the imperial capital by the review team half a month ago, and confidently handed the data to the Air Force.

"This is the turbofan 10A engine that Southwest Science and Industry has just completed finalization, although the thrust has not increased. However, through various improvements, the thrust-to-weight ratio of the engine has been improved, and the thrust loss of the engine has been reduced, and this engine is definitely a mature product. ”

The Navy just said what was going on, and the Air Force immediately blew up the thorns. You still have to use dual mid-thrust engines, don't you see that the J-82, which also uses two turbofan 10s, was abused by F15?

Thinking of this, the Air Force shook its head even more rattle, and the Air Force would definitely not make the same mistake a second time.

"That's not good, just the power system of the double middle push is far from enough, J-82 is a lesson from the past, if we want to reach the same level as the F15, we must have a double push."

After saying that, the Air Force was afraid that the Navy would continue to sink deeper and deeper into the pit of the middle push, so it immediately explained the source of the engine.

"The engine must have a large thrust turbofan, as for the model of the engine, in fact, this has been in development for a long time, the Taihang engine project that began in 86 is a high-thrust turbofan engine, using the same core machine of the F110 engine, Taihang will be able to have the performance comparable to F110."

Speaking of which, the Air Force is a beautiful yearning, if Taihang Engine can win the new generation of heavy aircraft project again this time, it will definitely be a great thing.

In the future, the same engine will be used for Project 10 and the new heavy aircraft, which will presumably be a great thing for the development of the engine and the logistics of the army.

Originally, I thought that the Air Force had some great engine, but when I heard it, I found out that it was something that had not even been manufactured as a prototype of the core aircraft, and the Navy absolutely could not believe the progress of this engine.

"No, no, the progress of the Taihang engine is too slow, and even the No. 10 project, which was originally planned to use the Taihang engine, has now switched to the Soviet AL31 engine. From this point of view, none of us can say exactly how long the development progress of this engine will be delayed. ”

The navy is completely afraid of the engine, and if it is not more than 80% sure of the engine, it will never dare to use it.

In order to prove that the Taihang engine is not suitable for use in the new aircraft, the navy has also questioned the engine development ability of Fengtian.

"We can take a look at the progress of various projects in Fengtian, the same engine, the turbofan 10 was finalized as soon as the full set of data was backed up from Southwest Science and Industry to Fengtian. Up to now, the turbofan 10A engine of Southwest Science and Industry has been finalized, but Fengtian only made the first batch of turbofan 10 engines, and I think the technical ability of Fengtian has indeed regressed! ”

Most of the Navy's current engines are switching to the products of Southwest Science and Industry, and there is not much need for Fengtian, so there is no longer any affection for speaking.

The Air Force was also speechless when he said this, and it took a long time to defend Fengtian with little confidence.

"It's not because Fengtian has put its main energy on the development of the Taihang engine! The progress of the turbofan 10 engine is naturally a little slow, anyway, the engine here will definitely be able to meet the production needs of the J-82. ”

Speaking of which, in fact, the Air Force also felt a little disgusted in his heart, to say that the turbofan 10 engine produced here in Fengtian now, if there was no turbofan 10A from Southwest Science and Industry, maybe the Air Force would happily use the turbofan 10.

But the Air Force now has a different voice, and the call for the J-82 to use a more advanced turbofan 10A engine is intensifying...... (To be continued.) )
