Rebirth of Military Workers

Chapter 949

No one thought, originally thought that the No. 10 project would have to wait at least several years before entering the prototype trial production link.

It has only been three years since its inception in 1984!

And now, Super-7B has just started prototype trial production, and has not even started its first flight, and the No. 10 project has to start prototype trial production again.

“Is there any technical problem?” Li Mingshan asked, “If there is no technical problem, you should enter the trial production link, and you must enter the trial production link.”

He was worried that 132 and 611 were stimulated by the 404 pattern.

Before the technical design has been completed, the prototype prototype is first produced, and the design is produced while the production is improved.

Project No. 10 is a key national defense project, and the Air Force pays the bill.

The 404 is different. It was originally a Sino-foreign joint research and development project. The research and development funds are partly undertaken by foreign countries, and even orders will be issued after design and production. 404 holds more funds than the entire country’s one-year military budget, so spending money is not a problem at all.

“Chief, after the F-9 lowered its original performance indicators in 1975, it was basically close to success when it was dismounted… The main reason for dismounting was that the technical difficulty was too great and the supporting system could not keep up. At present, no matter it is The control system or the radar system can already meet the conditions. And as the use changes, some designs in the original development process can be used in compliance…”

As the chief designer of J-10, Song Wencong naturally has a very high say in the entire project.

The original design index of the J-9 is even better than the No. 10 project in many aspects, but the only thing that is worse than the No. 10 project is its use.

After all, in that era, high-altitude high-speed was the mainstream development direction of the world.

Now fighters all over the world no longer pursue high altitude and high speed, but instead pursue the comprehensive performance of multi-mission mode.

In addition, some of the aerodynamic layouts proposed by Xie Kai were originally the original design of the J-10. In the design and development process of Super-7A and Super-7B, it was originally based on 611. Later, 404 continued to change from 601 to other domestic ones. Fighter design units are digging people, and they are all technical backbones, and they are slowly turning into cooperation.

Many designs come from 404. All the design team needs to do is to constantly demonstrate whether these designs are useful.

“The avionics system is also solved?”

“404 has developed a pulsed Doppler radar, which is a multi-control array focal plane radar. The maximum search range is 120 kilometers, the upward viewing range is 70 kilometers, the downward viewing range is 60 kilometers, and the rear view It’s 30 kilometers. It can track 16 targets at the same time and attack the 8 most threatening air targets… This radar is what they plan to use on Super-7B.” Xiong Hongyuan said quickly.

It’s not that he doesn’t want to say.

If the No. 10 project starts prototype trial production, the fire control radar will really have to be provided by 404.

After all, the J-10 and Super-7B are similar in many aspects, and the performance is equivalent, which makes it suspected of grabbing funds.

Whether it is Super-7A, Super-7B, or Project Ten, these three types of fighters are extremely similar in many respects.

Originally all came from the dismounted J-9.

“In this way, if the Super-7B adopts a twin-engine turbofan-6G, can the maximum take-off weight exceed 25 tons?” Li Mingshan didn’t get a reply from 404 before.

Now after listening to the introduction of 611, I think these guys in 404 have other thoughts.

It is said that the Super-7B is prepared for the domestic air force, but with the investment of Pakistanis, no matter how you think, I feel that this is not reassuring.

Unless 404 is prepared from the beginning, Super-7B is still for export!

With a dead weight of ten tons and a maximum take-off weight of 22 tons, it can carry 6 tons of ammunition even if it carries half of the fuel.

This performance is more than the ammunition that can be carried normally by the H-6, which is specially used for bombing.

“Theoretically, it is possible. The turbofan-6G is currently the most important research project of Dongfeng Power Plant. Although the performance is good, it has a fatal flaw…” Xiong Hongyuan worried that 404 would find them to settle the account.

After all, they don’t know what the 404 group is thinking.

The maximum take-off weight of Super-7A can obviously increase more, which is limited by them.

“What’s the problem?” Long Yaohua asked puzzledly.

He couldn’t understand it anymore.(Read more @ wuxiax.com)

It is said that it has been successfully developed, and that it has fatal flaws.

Can it be used if it has fatal flaws?

“The service life is too short…”

“How short?”

“Without afterburner, the service life exceeds 300 hours. Once the afterburner is turned on, especially when the afterburner is frequently used, the service life is less than 100 hours…” Even if the truth is told, it may affect the trial production of the No. 10 project. , The people of 132 Factory still have no hesitation on this.

Because of the excellent performance of the turbofan-6G, the requirements for materials and manufacturing processes are even higher.

The higher the combustion efficiency of the turbofan engine, the higher the temperature of the combustion chamber.

The issue of basic materials has always been the key to the development of equipment and technology in various fields in China.

Long Yaohua was silent.

Li Mingshan is no longer thinking about the 404 group of people wanting to export the dual-issue Super-7B in exchange for development funds.

Such a service life cannot be put into practical use at all.

The service life of an engine is less than 100 hours, and the production cost is several million. Then, the cost of using the engine for an hour of tens of thousands of dollars, plus other costs, a few are used for testing, the Air Force can still support it.

Even if one regiment is equipped, the entire air force will go bankrupt.

No wonder the 404 people did not say that the Air Force should place an order now, nor did they introduce the turbofan-6G to the Super-7B too much, but hope that the national aviation power system will mobilize the elites to work together to tackle key problems.

“If the No. 10 project uses a turbofan-6G engine, the cost…” Li Mingshan felt painful.

The military can’t handle such consumption.

“Chief, during the trial production process, we only need to allocate part of the funds, and we raise part of it ourselves.” Xiong Hongyuan was afraid that the above would disagree.

Now the 132 factory has a lot of production tasks, and other civilian units can also bring a lot of profits. There is still no problem supporting the prototype test and flight test of the No. 10 project.

Big deal, then cheekily rob 404 some of the funds.

The production unit of the turbofan-6G is Dongfeng Power Plant, which is a subsidiary of 404.

The No. 10 project uses the Dongfeng Power Plant’s engine that cannot be put into use at all. Can they do it without sharing some expenses?

Long Yaohua and Li Mingshan were going to go back, but after learning about these things, they naturally couldn’t leave.

It just so happened that Zheng Yucheng and the others were here, and they took the initiative to find them and asked to go to Dongfeng Power Plant to find out the situation.

Dongfeng Power Plant now integrates a lot of outstanding aero engine design and manufacturing technicians. At the same time, it is still updating production equipment. Liao Dongfeng is now the time for Chunfeng to be proud.

I heard that Long Yaohua, Li Mingshan and others came to inspect the factory and organized a group of people to line up a hundred meters from the factory entrance to welcome them.

Xie Kai is most unwelcome to this kind of thing, but it can’t happen now.

Long Yaohua and Li Mingshan crossed the welcome team and directly asked to go to the workshop to find out the situation, causing Liao Dongfeng to be troubled.

From time to time, secretly ask Zheng Yucheng and the others what the boss is doing.

“I heard that the service life of your turbofan-6 is less than 100 hours?” Long Yaohua asked before he even reached the workshop.

The complexions of Liao Dongfeng and Sun Hong suddenly changed.

“Chief, you can still use it for more than three hundred hours without the afterburner…”

“The fighter plane goes up to the sky without afterburner? Just fly and play like this? Or just evacuate after dropping a bomb or missile from the sky?” Li Mingshan asked rhetorically.

Liao Dongfeng was speechless.

Xie Kai saw that the two big guys were bad, and didn’t know where they were offending them, and gave Zheng Yucheng a wink. The two old guys won’t go up to be boring at this moment, and can only come forward by themselves, “Head, turbofan- 6 Although the ground test has been completed before, the materials and manufacturing process cannot keep up…”

“Everyone knows this.” Long Yaohua was very hot at the moment, “Are you going to continue to produce this kind of engines with a service life of less than 100 hours? Does the cost count?”

“Chief, our technology is developing…” Xie Kai explained hurriedly.

The service life is less than 100 hours, it is a problem of continuous afterburner.

No one can solve the domestic technical problems quickly.

“The inlet temperature of the turbofan-6G reaches 1210° in normal working conditions, and the inlet temperature of the afterburner thrust reaches 1370°. The current domestic high-temperature alloys cannot support long-term work…” Sun Hongye Explain quickly.

It’s not that they don’t work hard, and the materials and manufacturing processes can’t keep up.

“Chief, the new generation of nickel-based superalloys we have developed in cooperation with the Institute of Materials Science and Technology is currently in the experimental stage… As long as it succeeds, the problems encountered by the turbofan-6G engine will be effectively resolved.” Yaohua why they are angry.

The super-7B turbofan-6G engine used by the domestic air force!

“Yes, chief, not only the material problem will be solved, but even the manufacturing process, we have a large press, the impeller after die casting can withstand higher temperatures…” Xie Kai also understands why Long Yaohua and the others are angry .

The big guys are worried that they will use this to give it to the air force, and then the air force can’t afford it, they can justify exporting this kind of fighter.

No one can do anything about the engine.

The development of the turbofan-6G was discontinued in 1983 because the J-9 and Qiang-6 were dismantled, and finally, it was cancelled in 1984.

In history, the No. 10 project was started only in 1984, but the turbofan-6 could not meet the needs of the No. 10 project. The domestic and international engine technology level was further expanded until the turbofan supporting the J-10 in October 1987- The project was only established at 10.

Now, the butterfly of Xie Kai has fanned its wings, and the No. 10 project has been accelerated. No news has been heard about the Turbofan-10 project that 606 was supposed to do.

However, Dongfeng Power Plant is preparing to launch a large thrust engine with a thrust-to-weight ratio of more than 10!
