Chapter 1797 The most reassuring technology has made breakthroughs

"I was originally planning to use the turbofan-6 engine that Dongfeng Power Plant is improving, but now the No. 10 engineering technology level has been improved a lot, and it is aiming at a speed of Mach 2.2~2.4..."

History has not changed much.

After all, it has only been a few years, and even if technology has developed, it will not surpass too much.

It takes a long time for technology to develop.

Even if it is just a part of the technological improvement, the performance of Project No. 10 can be improved for the 611 design team.

"Is it still the engine limit?" Li Mingshan's voice felt a lot of helplessness.

This is really a headache.

The only thing in China is that Dadongfeng, which is used in the aerospace system to deliver express delivery between the intercontinental areas, is much weaker. After all, those things are disposable items and do not need to be reused at all and do not need to have too long service life.

“How do you think about it now?”

"There is no suitable engine yet. At that time, either reduce performance or you can only seek to purchase engines from the international level..."

"The Al-31 engine used by the Su-27 should be fine, and the rd-33 cannot satisfy the use." Xie Kai heard this next to him and made a suggestion.

The J-10 was first researched and there was no engine available, so it could only import Russian al-31 engines. While introducing small-scale engine production and providing it to the Air Force for use, it accelerated the development of domestic turbofan-10 engines.

"Imported engines from the Soviet Union again? When you produced the Super-7 before, they were stuck in the engine. The J-10 was used by domestically." Long Yaohua was a little dissatisfied, "Aren't you working on core aircraft?"

Until now, they no longer want to purchase engines from abroad.

The engine is the key.

Project No. 10 is different from Super-7a.

The Super-7a looks advanced, but in fact, those who know the inside story know that Hongqi Group is just like promoting the 359 tank, saying that a quasi-third-generation fighter with performance close to or meeting the third-generation aircraft standard in some aspects can have a real gap, which is very big.

This was originally intended to provide small countries with poor economic strength and want to have advanced fighter jets.

For some rich countries, this is a high-end trainer, and the prices are about the same.

The biggest problem now is on the engine.

How can they accept it?

The most advanced fighter engine is stuck in other countries. If they stop supplying it directly when it is really needed, what's wrong?

Reduce performance?

Long Yaohua and the others were even more reluctant.

If the performance is really to be reduced, the Air Force can directly use a dual-engine fighter like Super-7 B.

There is no need to build a new project with similar performance.

"Chief, it's not that we stretch our necks to others to lock them. Only by making them out as soon as possible and testing flights can we verify whether the design is reasonable, and then further improve them and improve the technology to make the performance better. Project No. 10 is not like the J-7. No matter how it is modified, unless the original aerodynamic appearance design is abandoned, there will be no great development prospects, at least it will not meet future national defense needs..." Xie Kai said very bluntly.

The improved design of the J-7 was continued by Factory 132 and 611. Even when Xie Kai left that world, he was still constantly modifying it.

Just like Xie Kai was worried about it like many netizens, the 26 English letters seemed to be not enough for the J-7, a veteran fighter that is known as the Chinese Air 59 and has strong vitality, there are too many domestic modifications.

There is even a model called the small J-10, but the reason is that it really wants to be the J-10. After it is modified, even Mi Gaoyang doesn't know it.

But in the end, even if the nose air intake is changed to the belly air intake, it still cannot be equipped with advanced radar.

Xie Kai proposed that he hoped that 611 would focus more experience on the Super-7 project, but they were unhappy and had to change the J-7.

The quality problems that have always existed in the J-7 production process have been truly effectively solved in recent years.

So what?

Even if the quality of the J-7 is reliable and the performance has been improved, it still lags behind. According to the Soviet division, the prototype of the J-7 is MiG-21. After multiple rounds of domestic design modifications, it can reach the third generation standard of the Soviet Union at most, and cannot be compared with the MiG-29 or the like.

"The J-7 has great potential for improvement. As long as the supporting facilities can keep up, it can even be transformed no less than the advanced international fighter jets..." Big Boss Tu stared at Xie Kai with dissatisfaction.

What do you do when you talk about things? What do you do when you talk about the J-7?

As the chief teacher, naturally, I don’t want others to say that the work they do is useless.

"Mr. Tu, you misunderstood what I mean." Xie Kaizhen didn't mean that, so he turned to Long Yaohua and others. "Chief, the United States and the Soviet Union, the new generation of stealth fighter jets have been researched for a long time, and even have models in service. If we dragged it down because of the engine, the gap between us will only be even bigger..."

Most people in China know the gap with international standards.

No one knows that many equipment will fall behind when they are made. There is no way to do this. When the skills are worse than others, they can only catch up step by step.

Long Yaohua and Li Mingshan also knew this situation.

Otherwise they wouldn't come to understand the situation.

"How is the progress of the Siyuku Fly-Trade Control System?" Li Mingshan changed the topic.

Mechanical control systems are too restrictive for advanced fighter jets and are difficult to meet performance requirements.

The Siyudu operating system is currently the mainstream technology in the world. There was no experience in China. Hongqi Group has provided a lot of funds and research directions based on the team of 611 institutes. In addition, sensors can also be provided in small batches. The progress has been quite large in recent years.

"Mr. Yang, please introduce it." Xie Kai looked at the young Chief Yang.

According to history, it is always true.

As the chief designer of the J-20, the first stealth fighter in China, Yang Wei was fooled by Xie Kai to create a 400-degree telex control system. Now he is asked to design a third-generation aircraft, and he probably won't be happy.

Looking at the big guys, the young boss Yang who had not grown up was not nervous at all.

"The four-dimensional tele-speed control system is very different from the originally expected one. Currently, a simple system is already used on the Super-7. Judging from various experimental data, it is still very reliable... The Iron Bird Platform used for ground comprehensive dynamic experiments is currently being installed. Once the Iron Bird Platform is completed, the subsequent research progress will be faster. With full permissions, three-axis and four-percent readings, digital tele-speed control system can be simulated and simulated on it..."

"In other words, it's about to succeed?" Xie Kai was immediately overjoyed.

A genius is indeed a genius.

This progress is much faster than before.

"Consultant Xie, this cannot be said to be about to succeed. It is just one step further from success. The ground can simulate the experimental flight process, verify whether there is any problem with the design of the entire system, and optimize the entire system..." Yang Wei looked at Xie Kai with a smile and shook his head.

Although it was not successful, as long as the Iron Bird Platform was created, many designs could be directly tested.

The progress will be much faster.

"The telex system will make the control of fighter jets easier, and the air will be more flexible and maneuverable, and it will fill the gap in the country. OK, very good!" Long Yaohua was immediately overjoyed.

The fly-by-wire control system can effectively improve the operating performance of the fighter.

This is also used on Super-7a. It is not a fully authorized three-axis and four-degree numerical telex system, but a single-axis longitudinal stabilization system that integrates the mechanical operating system.

This thing is the first technical achievement in China to start researching telex control systems.

In 1987, Chen Fei and other units began to use the J-6 to modify the aerial flight test simulation research aircraft, that is, a single-axis longitudinally variable stability aircraft, codenamed bw-1, no longer uses mechanical joysticks, but uses pure digital telex control systems and use flight control computers to operate flights. In 1990, it won the first prize of national technological progress.

This can also fill the gap in this area in China.

However, since it only uses single-axis fly-by-wire control, except for the longitudinal pitch direction of the aircraft, the other directions are still traditional mechanical operations. Many complex aerial flight simulations cannot be undertaken by this technology verification aircraft. Although the technical content is very high and the progress is great, it is not practical.

Chen Huoyi's research now uses the J-8 as the target aircraft and has achieved many achievements, but it is not a three-axis and four-degree operating system.

The 611 side has the most difficult challenge. If it weren't for Hongqi Group's large amount of money and the supporting facilities of many units, the progress would not be so fast.

"The No. 10 Project is also integrated into this system. When the test flight is completed, even if it cannot catch up with the most advanced level of fighter jets in the world, it will not be too far away and should reach a medium level." Boss Song told the leaders such as Long Yaohua that their No. 10 Project will have much higher performance than the standards originally given by the military.

What’s even happier is Xie Kai.

If the progress of the Siyuda Fly-Travel operating system is not fast, the J-10 will not use such a control system at the beginning. Instead, it will wait until the test flight is completed, and the Yang Wei team will carry out optimization design, public relations, design and finalization work, and finally it will be not until 2004 to complete the design and finalization.

Xie Kai doesn't want to wait that long.

Otherwise, he would not have asked 611 to let Yang Wei and the others do public relations for the four-degree telex control system at the beginning.

The core of the entire four-degree telematic control system is the flight control system. The computer involved is invested heavily; the sensors and controllers involved are also invested heavily...

With basic supporting facilities, the rest of the entire team will require the entire team to perfect this system.

Not only hardware, but also software systems.

Logic circuits, servo systems, computing circuits, etc. all need to be effectively integrated.

As soon as Tiebird Tian comes out, whether these systems have any problems can be directly simulated and run, and can be easily monitored by simulating them on the Tiebird Platform.

Find out the problem and modify the design, and things will be much easier.
