Lao Zhou has entered this project from the very beginning, until now, his hair has turned gray, his face is full of exhaustion, and now, it is time to fight the tough battle.

They're going to put this equipment on the plane! And when assembling, there will be all kinds of problems, because they are not aircraft designers, and they do not have complete experience in surveying and mapping imitation of J-6 fighters, and many times, they have to cross the river by feeling the stones, which is a big problem.

For example, now, Lao Zhou is worrying about the tail servo with people.

Now it is only a one-way control, that is, fly-by-wire control in the pitch direction, only the elevator needs to be improved, it used to be a hydraulic servo, but now, it is necessary to improve the electronically controlled servo, and at the same time retain the mechanical backup, the tail of this J-6, it is quite crowded, after all, the tail of the J-6 has two engines, the original position is compact, and now there are more new servos, which is really a difficult thing to solve.

"Qin Feng, are you here?" Lao Zhou glanced at Qin Feng, and then at Gu Tingting, who was busy in the equipment cabin in the middle, this Tingting is really, Qin Feng is back, and he doesn't rest and rest, he still came so early, these two have not seen each other for a few months.

"Well, I'll come back and see." Qin Feng said to Lao Zhou: "Our stabilizer is making good progress." ”

"Yes, it's now in the final stage, and after the assembly is complete, it's ready for test flight." Lao Zhou said.

Qin Feng approached in stride, didn't look at anything else, first went straight to the cockpit, after all, for pilots, the cockpit is a window for them to interact with the aircraft, and the first thing they look at is the cockpit.

The instruments in the cockpit are no different from before, they are exactly the same, but on the operation panel on the side, some switches have been added, such as the main power switch of the fly-by-wire operating system, the control circuit switch, etc., just these, there is no instrument display and the like.

Fly-by-wire control, and no need for a display interface, is different from radar fire control, but all the data is in the equipment compartment in the middle, where there is also a data interface, every time the flight is finished, the data can be copied down for analysis. Gu Tingting was busy working below, and she didn't go to see Qin Feng, these two people were like they had quarreled, only the two of them knew each other's intentions when they looked at each other.

You're too busy to bother you.

You see for yourself, and if you need to explain, you will talk about it.

In this way, Qin Feng didn't talk to Gu Tingting, looking at the layout inside the cockpit, and then looking at the operating lever inside, the mechanism under the operating lever is also quite special.

"We use a training aircraft, originally the front and rear cabin operating rods are linked, but now, it has been changed to fly-by-wire control, so the linkage device has been canceled, one of the equipment, replaced by our electronic control system, these hardware, are our own research and development, when the test flight, the risk is very high."

Although there is no problem with the hardware developed by the company during the test, there may still be various unexpected failures after getting on the plane, so the risk of test flight is very great.

"It's okay, we have two sets anyway, it's a big deal to continue to use hydraulics, and then analyze it when we come back." Qin Feng said: "We came up by ourselves, all the technologies are in our own hands, with these technologies, we will improve them in the future, it will be very convenient." ”

Although it can be imported from abroad, if it is imported from abroad, on the one hand, the price is high, and on the other hand, it is impossible to master all the technology, so although Mr. Gu has introduced German equipment, it has no impact on his own research and development.

"In our test flight yard, it seems that there are a few fewer test pilots." Qin Feng muttered, when he was passing by just now, he felt that something was wrong, there was no one in there, and everyone who should have taken a test flight went to test flight, but looking at the wardrobe, there were many unlocks, which meant that there were fewer people.

"yes, don't you know? Now, a new batch of test pilots is being selected across the country. Lao Zhou said.

Qin Feng just came from the capital, and he doesn't know about these news, but now that Lao Zhou said this, Qin Feng was very surprised, and selected new test pilots across the country?

What's that for?

Is it just for the sake of test flights of third-generation aircraft?

"What are they for? Are we going to engage in manned space flight again? Qin Feng asked.

Project No. 10 is a confidential project, so Qin Feng doesn't know if Lao Zhou knows, and there are so many people nearby, there must be some people who don't have the authority to know, and now, Qin Feng can only guess in other directions.

Twenty years ago, the country actually launched the manned space program, and at that time it was still selecting astronauts within the army, and the criteria were quite strict.

Now, is it time to select astronauts again?

Knowingly asked, Lao Zhou said that it was a test pilot, not an astronaut.

"Of course not, our country's aviation projects do not have enough funds, let alone aerospace projects, it is said that for the test flight of new types of fighters, we plan to select a batch from the whole army, the competition is quite fierce, our test pilots here also went, I don't know how many can be selected, this matter, you don't know, right? Oh, yes, you don't have to accept this kind of audition at all, you belong to the kind of direct selection. ”

When Lao Zhou said this, even Qin Feng was embarrassed, Qin Feng seemed to have understood something, this should be prepared for Project No. 10.

No. 10 project, will be the first domestic third-generation aircraft, and the previous aircraft is very different, the most direct speaking, the cockpit display, to the head-up display and the lower display-based, all are computer screen interface display, and the current operation is completely different.

Needless to say, now domestic fighters, except for the J-7M, there is no head-up display at all, everyone is accustomed to using instruments to fight, even if it is equipped with the J-7M troops, some pilots feel that the flat display is too much of a hindrance, the first thing to do when you go up is to turn it off, just like the cars of later generations, turn off the automatic start and stop when you go up.

Therefore, it is a huge challenge to select a new generation of test pilots from all over the country, and they have to adapt to the new display interface.

What about yourself? I'm sure I'm fine, but others are different, so how can I make them do this well? General Lin's words appeared in my ears again, you not only have to be able to fly yourself, but also take others to fly!
