The trip to Europe has ended, and when he returned to the test flight institute again, Qin Feng had a dream-like feeling, and then looked at the J-8 fighter that was landing in front of him, and instantly felt a tattered feeling.

Can this aircraft take off at a high angle of attack? Can you fly a figure of eight with such a small radius in the sky? Can you land with the brakes?

Compared with foreign countries, we are at least 20 years behind!

However, this thought quickly stopped in my heart, no matter how good the Mirage 2000 is, it is someone else's, no matter how bad your own J-8 is, it is also your own, knowing the gap, that is, to catch up!

"Brother Wang, how far has our test flight been conducted?" Seeing that the J-8 came to a steady stop and Wang Yang came out of it, Qin Feng immediately went up and asked.

Wang Yang had a smile on his face: "Hey, you kid is back, I heard that I went to France to open my eyes, did the capitalist world fascinate your eyes?" ”

Qin Feng smiled: "Brother Wang, when you go out, you know how small we are, when did this test flight start?" ”

Before going out, everyone was still busy solving the problem of the sudden shutdown of the engine, which was caused by the mismatch of the intake tract, which was difficult to solve, and the method proposed by Qin Feng was also very complicated, and I don't know how long it would take to solve it.

But now, looking at the fact that the fighter is already flying, it seems that it has been solved.

"The day before yesterday, we made this complex linkage mechanism, according to your assumption, at high altitude, as soon as we pull the rod, the air intake cone will retract, not to mention, it's really in charge, and now this problem has been solved." Wang Yang said.

This thing, no matter how complicated it is, as long as you can come up with it, everyone can figure it out.

Hearing Wang Yang's words, Qin Feng also had a smile on his face, okay, this is a big problem, in the past, the designers wanted to repay the debt, it was counted as an accidental failure, and they couldn't let it go, but now no matter how they do it, as long as the problem is solved, it will be fine.

"Let's go, let's go to the conference room together, now, there are new challenges waiting for us." Wang Yang said, pulling Qin Feng and walking to the conference room at the back.

When everyone saw Qin Feng, they were all happy, even Lao Liu and Lao Wang, seeing Qin Feng greeting him, they also agreed with a smile, the past is even if it is over, everything must look forward.

"Okay, let's first welcome Comrade Qin Feng back, and ask him to tell everyone about this experience, which will also open our eyes." Mr. Gu said.

So, Qin Feng told what he had seen and heard at the air show this time, and everyone felt that they had never heard of it before, and they had never seen it, and this plane could actually directly step on the brakes?

And the maneuvers one by one, it's incredible.

Everyone sighed, and Mr. Gu said: "There is a big gap between us and the international advanced level, and now, we still have to base ourselves on our existing equipment, and let's talk about the next test flight of our fighters." ”

"I'll tell you about it." Commander Li of the test flight regiment looked at everyone: "With the solution of the problem of supersonic tremor and sudden engine shutdown, it seems that there is no big problem now, there is only one thing left to continue to expand the flight envelope, and the high-altitude and high-speed test flight will be completed soon, and next, we have a more risky subject, low-altitude and high-speed speed." ”

Low altitude and large speed!

Hearing this subject, the expression on Qin Feng's face also became serious, if you want to talk about risk, of course the risk of this subject is high.

In the past, flying at high altitude and high speed, even if the engine was turned off, at least there was still altitude, and everyone had time to restart the engine, or even parachute, but it was not possible to fly at low altitude and high speed.

Low altitude means that the altitude is very low, and the speed is very high, and it is necessary to fly at supersonic speed!

The J-8 was originally a high-altitude and high-speed fighter, but during the test flight, if you want to leave no regrets, this subject will also be carried out.

What is this subject used for?

Now, the high altitude is unobstructed, all kinds of ground radars can guard the high altitude to death, fighter jets fly under the nose of the radar, if you want to be able to evade the enemy's radar, then you can only fly ultra-low altitude.

Especially now, many of the Soviets' bombers are planning to adopt the method of low-altitude and high-speed surprise attacks, and although their fighters intercept at high altitudes, they must also be able to turn to low altitudes at any time.

"We have a lot of problems in this subject, first of all, the problem of the test flight site." Commander Li said: "When we test the flight, we have to exceed the speed of sound, and at this time, it will bring a sonic boom to the ground, so it will have a great impact on the ground." ”

The crowd nodded.

"We can test fly at sea." Said one of the test pilots.

Test flights on land, that will bring a lot of trouble to the inhabitants on land, and there is no need for the sea, let's shift our positions.

"If you can go to sea for a test flight, you can avoid this problem, but to solve the problems of life-saving and interference with fishermen's production, etc., there are many aspects, it takes a lot of time to apply and coordinate, and it is possible to compensate fishermen for their losses, involving a certain amount of money, these are not easy problems to solve." Head Li said.

There are no more inhabitants at sea, and there are still fishermen, and they must be compensated for disturbing the fishermen and causing losses.

These may be solved, but there is another problem that is more difficult to solve, and that is lifesaving.

What to do once a plane crashes?

How to rescue on the endless sea?

Helicopters? There are only backward Z-5 helicopters in China, and those that can't fly to the sea rely on fishing boats? By the time the fishing boats pass, I'm afraid it's too late.

Needless to say, it is not yet the 80s, even in later generations, when the hero Wang Wei's fighter crashed into the sea, the remains of the hero were still not found.

Everyone is not afraid of sacrifice, but what about fighters? The fighter is the property of the state, and what about the test flight data on the fighter?

"Commander Li, I think we can test fly on land." At this time, Qin Feng spoke.

Everyone immediately looked at Qin Feng and listened to what Qin Feng had to say.

"Yes, we may produce a sonic boom, but because we fly at a low altitude, the range of impact of the sonic boom is relatively small, so we will conduct the test flight in the airspace near the test flight yard, as long as we choose a lot without a village for the test flight, so that the ground safety will not be endangered."

Every time Qin Feng has an opinion, he can provide you with ideas, and now Qin Feng says this, it is indeed good, sea test flight, to coordinate, to rescue, too complicated, delay time, it is okay on land, although we have a big movement, but we have a small scope!

"Do we have to fly in this subject?" At this moment, Lao Wang spoke again.
