"Let's go, let's have a meeting." After reluctantly looking at this plane, it is estimated that it will soon be dangling in the test flight yard with a large plate, so there will be time in the future, and after each test flight, there will be a meeting.

"Today's test flight subjects have been completed very well, the data have come out, Comrade Qin Feng's flight is quite accurate, and everything that should be flown has been flown out." Zhou Lao said: "Our next subject is the maximum circling overload subject, the test flight of this subject, we let..."

Before Zhou Lao's words fell, Tang Gang raised his hand: "Old Zhou, I'll fly this subject!" ”

What, you come to fly? Zhou Lao looked at Tang Gang, and everyone else also looked at Tang Gang, feeling very strange, when did Tang Gang take the initiative so much?

This subject, there is no danger to life, however, it is a great test for the body.

The maximum circling overload, that is, to carry out a circling flight, in the flight, the body will bear the test of centrifugal force, will tear all the muscles in the body, although there is an anti-load suit, but it is only to let the blood of the lower body flow back, the upper body still relies on its own physical strength to carry over.

This is also different from instantaneous hovering, when flying before, it was mainly instantaneous hovering, and the overload may be very large at once, even reaching 9G, but the duration is very short, and now it is different, now this overload, you must hold on, one circle, two circles, when to fly, when to come down.

In addition to the muscles of the whole body, the cervical spine is also a great test, after all, the head is connected by the cervical spine, and doing this kind of high overload maneuver may cause permanent damage to the body.

Tang Gang took the initiative to ask Ying, that was to protect Qin Feng, you must know that Qin Feng is now in his forties, he has been flying for more than 20 years, and his health is not as good as when he was a young man.

"No, although you are also flying, but you have always been flying avionics, you have not done a large overload maneuver, so, if you are asked to fly, you may not be able to fly, you know, flying like this is also a great test for the body."

When the test flight is carried out, it is necessary to fly to the required value, if it can't fly, then someone has to fly again, this kind of large overload, if it flies too fiercely, it may cause permanent damage to the aircraft structure, of course, under the control of digital electric drive, it will definitely not allow such a situation to occur, but it can be completed at one time, it must be completed at one time.

Up to now, all kinds of maneuvers with large overloads were flown by Qin Feng, and Tang Gang flew with avionics tests that were flat and stable, so Qin Feng immediately denied it.

"I'll fly it."

"No, Brother Feng, this kind of flight is very harmful to the body." Tang Gang said nervously.

"Hmph, you mean, I'm old?" Qin Feng said: "Lian Po is old, can you still eat?" When we go to the cafeteria in a while, let's compare who eats more? ”

"Since Comrade Qin Feng insists, then Comrade Qin Feng will fly, just fly once, and strive to fly to the experimental value, if you can't fly, then Tang Gang will fly." Zhou Lao spoke.

In fact, Zhou Lao is also inclined to Qin Feng to fly, after all, Qin Fengfei has the most experience, and the Air Force is pointing out to let Qin Feng fly in any subject, and he is most assured, now this subject is a little hurtful, I hope Qin Feng can fly.

Qin Feng was ready, and the next day, it was a good weather for flying, as usual, starting the engine, taking off, and Qin Feng started the test flight again.

When it was time to take off, I also took a look at the tarmac where the Il-76 was located, and found that scaffolding had been erected there, and it seemed that the radome was about to be installed.

In fact, this radome is really experienced in China, when I was researching the Air Police No. 1, I once installed a radome on the back of the Tu-4 bomber, this radome needs high wave transmission materials, and the nose of our own fighter is also similar, as long as the strength can be guaranteed.

Even if it blows through the wind tunnel, it has to be like this to carry out the actual test flight.

Retracted his thoughts, let's fly my own subjects.

"001 report, height 1,000, speed Mach 1.2, ready for experiment." Qin Feng said, the afterburner was fully opened, the muscles in his body were tense, he pedaled the rudder, pushed the operating lever, and pressed to the maximum slope.

The instantaneous circling angular velocity of more than 200 degrees per second is not a joke, it is a spinning of the sky in an instant, if it was in the past, it would have been changed by turning 90 degrees, and 180 degrees.

But not now.

Under the strong surging power, the fighter plane exerted its strength and entered the circle of large overload, Qin Feng instantly felt his body, and was pushed to the outside of the seat fiercely, and then, the seat belt tightened his body again, which was estimated to be the same as the seat belt of the car suddenly braking at high speed.

When circling, the speed will drop sharply, and the afterburner will be fully turned on, which is to compensate for the loss of speed, but even so, the speed is still decreasing.

Qin Feng's eyes began to be dizzy, he continued to insist, one circle, two circles, the feeling from his body made him feel like his soul had been stripped of his body, he insisted on continuing to stop, and at the same time looked at the number on the flat display in front of him.

Instantaneous circling, you can reach 9G at once, but it is difficult to reach 9G when it is stable and circling, and it is even more difficult to maintain 9G for a long time.

Qin Feng continued to grit his teeth and insist, insisting, the speed of the fighter was decreasing, until it was reduced to Mach 0.6, he felt that his body was really unbearable, and let go of the operating lever.

That's the benefit of fly-by-wire, as long as you release the joystick, the fighter will become level flight!

Qin Feng lay on the seat all of a sudden, with no strength in his body, and let the fighter enter the level flight state by itself, every muscle in his body was sore, like running a marathon, and there was a constant sharp pain in his back.

You can't have a problem with your spine, right? If something really goes wrong, then I'm afraid I will say goodbye to flying for the rest of my life, at this time, Qin Feng is still a little afraid. He is not afraid of sacrifice, he is afraid that he is still alive, but he can't fly.

Sweat kept coming out, Qin Feng gasped for breath, and the voice of the ground came from the earphones: "001, how is the situation?" 001, report the situation! ”

"001 reports, the flight maneuver has been completed, and now returns." Qin Feng shouted over the radio, he sat up straight, and began to operate the fighter to return to the field.

I have never felt that the time is so long like this time, there is a constant feeling of pain in the neck, and there is something wrong with the cervical spine, Qin Feng gritted his teeth and persevered, saw the runway of the test flight institute, and then, concentrated, landed!
