In fact, when he flew the Phantom 2000 before, Qin Feng had already flown fly-by-wire control, and he also knew the characteristics of the fly-by-wire control system, which was completely different from ordinary hydraulically operated aircraft.

For example, in the climbing state, if an ordinary aircraft wants to be flattened, it has to push the operating lever forward, because the tail must be cocked up so that the head can be lowered, but if the fly-by-wire operation is to be flattened, it is to release the operating lever, and when the operating lever is not exerted force, it is to tell the flight control computer, I want to fly level!

How was the plane flattened? This does not require the pilot to think about how to operate each rudder surface, that is something that the computer has to consider, and the pilot only needs to send instructions to the computer through the operating stick.

Now, Qin Feng is still following the operation of the second-generation aircraft, pushing the operating lever forward during the climb, and the fighter knows that this is about to dive.

Qin Feng still flew over the Phantom 2000, he was more experienced, and he still made such a joke, if Qin Feng hadn't flown over, then I am afraid that he would be even more at a loss at this time.

What does this mean?

Experience is important, but sometimes, experience can be counterproductive!

In particular, from the modification of the second-generation aircraft to the third-generation aircraft, from the improvement of hydraulic operation to digital fly-by-wire, there are completely different modes of operation, and at such times, it is necessary to undergo special training before being able to fly the third-generation aircraft, and these test pilots are no exception.

In the process of research and development, the domestic new J should also develop a similar simulator, so that the pilot can adapt to it and be proficient in the simulator before he can fly the new J, otherwise, it is very dangerous!

These thoughts flashed through Qin Feng's mind, and then, Qin Feng let go of the operating lever.

The heaven and earth line appeared on the curved screen in front, and at the same time, the cockpit was also flattened, in fact, when Qin Feng was operating just now, the cockpit also rotated synchronously, but he was too attentive on it, and he didn't notice this change at all, as a pilot, he often experienced the rotation of the sky and the earth, and the change of body posture, but instead of being so sensitive, if an ordinary person went up, under the action just now, he would definitely have vomited.

At this time, the altitude of one thousand is considered to be low-altitude, Qin Feng has just been in the process of test flight, and has not released the afterburner, until now the plane has been flattened, it can be regarded as turning off the afterburner, this climb makes him remember it vividly, the advanced engine, the performance of the fighter is so useful!

If you want to develop a qualified third-generation aircraft, you must have an advanced engine, and the only thing that can be used in China now is the turbojet-15, which is really unable to support the new J-1!

Qin Feng, what are they doing here? Flying this simulator is to experience the operation of the third-generation aircraft, including the boundaries of the various flight envelopes, and now, since it has flown on, Qin Feng naturally has to use the most violent way.

Anyway, you don't have to worry about the brutal operation causing the crash, which is why the simulator gives people much less psychological pressure.

Continue to turn on the afterburner, at a height of a thousand meters, and see how fast you can fly!

Using different engines, different aerodynamic shapes, the maximum speed is also different, and now in the research and development of third-generation aircraft, the air forces of many countries do not value the maximum speed.

The kind of MiG-25 is destined to be a passing thing, and excellent maneuverability is a key indicator of the third-generation aircraft.

There was a surging thrust from the tail, and at an altitude of one thousand meters, you could see pieces of white clouds floating on the screen, and with white clouds, you could realize how fast the speed was, such as now, the clouds seemed to be rushing to the face, fleeting. The heads-up numbers in front of them are also beating fast.

Accelerate, accelerate!

When you reach around Mach 0.8, you can feel that the acceleration has slowed down.

The Lion fighter uses a turbojet engine, which was originally adapted to high altitudes and high speeds, and is now at low altitudes, which is one reason, and as for another, it is definitely the influence of the air intake.

This aircraft directly uses the air intake of the F-16 fighter, under normal circumstances, the air intake efficiency is quite high, but it's not adjustable, it can only be optimized for a certain section of speed, the acceleration is very fierce, when the speed is fast, the huge air intake, but there is resistance, the acceleration is not as fast as just now, at low altitude, the air is dense, and the speed is more difficult to increase.

The numbers continued to beat, and at the same time, in front of the nose of the aircraft, white clouds began to gather, more and more clouds, into the shape of a sharp cone, suddenly, a soft bang, and then, the whole world fell silent.

Qin Feng has entered the supersonic speed, he left the sound behind, including the engine, the program of this simulator is so realistic, and the simulation of the sonic boom is very realistic.

Although it was not specifically born for combat, but, without a plug-in, it can still fly supersonic, this is the exploration of its envelope, when flying the Jian-8, the low-altitude and high-speed Qin Feng is still fresh in his memory, at that time, he was almost flying at the risk of death, and now, it is just an experience.

Then, Qin Feng turned off the afterburner and pulled the operating lever back violently! Pull to the head!

At supersonic speeds, the fighter will become very vulnerable, for example, the maximum overload of the fighter is 9G, it must be indicated in what flight envelope, subsonic speed is good to say, but in the case of supersonic speed, if you fly such an overload, it will definitely be a result, the plane will be destroyed and people will die!

What now?

Qin Feng pulled the fighter's operating lever to his head, just to experience whether he could pull the fighter apart, and at the same time as he pulled it up, he also swept the screen below with the corner of his eye, looking at an overload display inside.

4G overload.

Although he pulled to the maximum, the fighter's own fly-by-wire control system was limited to avoid the pilot's misoperation and pulled the fighter apart.

The cone-shaped cloud in front of it quickly disappeared, and the nose of the fighter plane was slowly rising, and after the fuselage was raised, the oncoming resistance was greater, and the speed of the fighter was rapidly decreasing.

What is it called? Fly without worry!

When flying J-6, J-7, and J-8 aircraft, pilots must always remember the flight envelope, not exceed a certain limit, and dare not let go of their hands and feet when fighting, always worrying that the aircraft will fall into a terrible tailspin and other unexpected situations.

Now, with fly-by-wire control, there's no need to worry, if your actions put the aircraft in danger, the flight controller computer will refuse to do it!

No matter how you play, you just can't play badly, and you can use such easy-to-understand language to explain the performance of fly-by-wire fighters, so pilots can focus more on air combat.
