Although the political situation in the Soviet Union has been unstable in the past two years, when they heard the news, everyone present was chuckling in their hearts.

It's troublesome this time!

The USSR is gone, so the contract signed with the USSR still counts? 24 Su-27 fighters, pinning the hope of the Air Force, the J-10 fighters in front of them are still far from being officially put into service, and the Air Force is all looking forward to these fighters to support the sky of the motherland, as a result, the Soviet Union is gone!

Even Song Lao's heart chuckled, he didn't expect such a major change to occur suddenly.

For Chengdu, two aircraft are now being carried out at the same time, one is the current J-10, and the other is the super seven, because the 132 factory and the 611 institute have been merged, so the super seven project, 611 of course is also very attentive.

After repeated negotiations, the engine of the super seven has been preliminarily selected for the RD33 engine used on the MiG-29, and after the adaptability of the single engine, it can be used on the super seven, and another aircraft of the 611 institute, the J-10, may also use the Al31F engine of the Su-27, so that the aircraft of the 611 institute may be based on the engine provided by the Soviet Union, but at this most critical time, the Soviet Union actually did not have it!

"We are quite happy with the aircraft." General Lin said: "However, the follow-up seminar of this plane, let's put it on hold for the time being, and now, we need to go back and discuss countermeasures to deal with emergencies." ”

With the sudden collapse of the Soviet Union, the 906 project was once again overshadowed, which could not help but make everyone think of a model of peace, and the modification of the J-8-2 project was going smoothly, but what was the result? Suddenly, there was an unexpected change and it stopped!

"Yes, General Lin, we can accept it." Song Lao said to General Lin: "Therefore, we also ask our superiors to consider and continue to increase investment to complete the research and development of turbojet 15. ”

The current metal model of the J-10 uses the turbojet 15 engine, which is a backward model that imitates the MiG-23 engine, but it is a technology that can be mastered by itself, as long as it makes great efforts to engage in research and development, and now, if you rashly use the third uncle, it may face the risk of being cut off from the engine.

History is always strikingly similar.

Of course, Song Lao also has his own considerations, the volume of the two engines, the flow rate, etc. are very different, if you want to change the hair, there is still a lot of task!

"yes, we need to think about it." General Lin said, everyone took one last look at the all-metal model of the J-10, and left one after another, for the Air Force, the introduction of the Su-27 is the top priority.

Everyone left, but Qin Feng didn't leave, this kind of coping strategy, it was not Qin Feng's turn to interject, he has been in the test flight institute now, and he feels that he is getting farther and farther away from Jian-10, obviously he is the appointed chief test pilot, but he has been busy with other projects, the main reason is that the progress of this aircraft is too delayed.

Qin Feng sat in the cockpit, the display screen was still shining, Qin Feng's hand stroked the operating lever, the shape of this operating lever was pinched out by him with plasticine, the arrangement of each button was decided after repeated research, the role of the hand not leaving the lever in air combat is very great, this aircraft is cross-era.

He looked at the numbers on the display above and knew that those were the numbers initialized by the system, and it would be nice if he could fly up and watch the numbers jump one by one!

"You're not leaving?" After sending everyone away, when Song Lao came back, he couldn't help but ask when he saw Qin Feng here.

"yes." Qin Feng said: "Old Song, how long is it until the first flight of our plane?" ”

I'm still waiting to fly it!

"Qin Feng, do you know what the biggest problem is in the development of this aircraft?" Song Lao didn't answer Qin Feng directly, just stood on the platform next to him, holding on to the railing, and looked at Qin Feng who was fiddling with the cockpit equipment.

"If it makes its first flight, many weapon systems can be left empty." Qin Feng said: "The electronic system can be later, but the engine, the body, and the flight control must be complete, and the problems we are facing, the engine is very tangled now, but it is not the most complicated, the most complicated, or the flight control." ”

"That's right, it's the flight controller!" Song Lao said: "A few years ago, the Jian-8 ACT in Shenyang fell off on its first flight, because of the problem of flight control, for them, if they fall a plane, it will not hurt their vitality, but for us, if they fall a plane, it may be a catastrophe!" ”

Song Lao's biggest pressure is the flight control, after all, this is a canard layout of the fighter, congenitally static unstable, this is the first time in the domestic design, now, the engine can also use turbojet 15 first, however, the flight control can not have any problems!

The domestic technical force is very weak, so even foreign experts are not optimistic, believing that the country is at the level of primary school students in this regard, even in the West, in the research and development of the telex system, there are frequent failures, F-16 once fell because of the flight control, and Su-27, even fell several.

Song Lao is under a lot of pressure, and for the 611 Institute, if he falls, he may lose the entire project, which is completely like walking on a single-plank bridge, and there are dangers everywhere.

"I remember, Yang Gong is in charge, right?" Qin Feng remembers very well that back then, Song Lao warmly retained Yang Gong and entrusted him with important tasks, and Yang Gong was responsible for the design of the most difficult flight control.

A simple BM-1 flight controller, let his wife Gu Tingting participate in the team, went through a lot of twists and turns, and finally successfully completed the flight, that is just a single-axis telex, the current aircraft, what is needed is three axles and four redundant digital telex, in addition to the hardware system, the flight control program, is also crucial.

"yes, he's in charge." Song Lao said: "This all-metal prototype, after being inspected by the leadership, we will soon transform it into an iron bird test bench for all-round verification of the flight control system!" ”

Why do foreign countries say that they don't have this technology in China? It is because there is no relevant test bench in China, if you want to study flight control, you must have a special test bench!

Now, the J-10 project is finally about to come to the most critical step, only after repeated all-round experiments on the test bench, all kinds of situations are thoroughly studied, can it really have a flight state!

"Although we have a lot of young men working hard, we still lack manpower, so, Qin Feng, can you do your wife's work and let her come to help us?" Song Lao said.
