"006 called the base, has flown to the test flight airspace, and asked to accelerate to the maximum and then dive from 500 meters."

At this time, Qin Feng piloted the fighter again, looking at the Gobi in the distance, Qin Feng's face was full of determination, these days, little by little test flight, little by little increase in speed, has made Qin Feng have a deeper understanding of this fighter, it will definitely be able to withstand this kind of test flight!

Exceeding the speed of sound in a dive is something that any supersonic aircraft can do.

"Yes, please stay safe." The voice of the head of the test flight group came from inside the headphones.

"Understood." Qin Feng turned on the afterburner.

At this time, the altitude is higher, so the maximum speed of the fighter can reach even greater, Qin Feng watched the speedometer in front of him continue to increase, five hundred, nine hundred, when it is increased to one thousand, the operating lever is pushed to the head again, and it is impossible to continue to increase the speed.

If you want to continue to increase your speed, there is only one way, and that is to dive!

The Gobi on both sides were rapidly retreating, and Qin Feng's hand closed the afterburner.

As the thrust of the engine in the tail weakened, the speed of the fighter suddenly dropped, and Qin Feng's hand was still pushing the operating lever, so the tail rudder of the fighter was prying the head towards the earth!

The fighter plane roared down from 500 meters in the air, and in front of Qin Feng, the earth was rushing towards him, as if a person was returning to his mother earth, but for a well-trained pilot, this scene was very terrifying.

Ordinary pilots will involuntarily pull the operating stick, afraid that the fighter will contact the ground, and afraid that they will not be able to pull it up because of the lack of altitude.

But Qin Feng can't, Qin Feng's fighter plane has to keep going downward, otherwise, how can it detect the data of two hundred meters?

On the Gobi Desert, the withered yellow weeds and the wind-blown yellow sand can be seen clearly, and the distance is getting closer and closer!

Qin Feng glanced at the altimeter out of the corner of his eye, and when the height was two hundred and fifty meters, he began to pull the operating lever.

Suddenly, his body was pushed up by a strong force, and his whole body wanted to leave the seat, and his eyes involuntarily wanted to bulge outward.

This kind of overload from the dive and then up, the human body is quite terrible, yesterday, Qin Feng studied more information, some pilots because of the fierce work, even pulled out all the two eyeballs, and threw them on the cockpit glass!

However, no matter how big the risk is, Qin Feng has to test fly, he has no choice!

The fighter continued to go down, two hundred and thirty meters, two hundred and ten meters, and when it was two hundred and twenty meters, the fighter had just leveled out!

At this point, the speedometer has reached one thousand and one!

Sure enough, using dive to increase speed, that is the only way, in level flight can barely fly to a thousand, and now from a dive down from five hundred meters in the air, it has already rushed to one thousand!

At this speed, it is impossible to maintain level flight under any circumstances, and as soon as the fighter is leveled, the nose of the aircraft has been raised again and it has begun to soar towards the sky.

It's flying again!

Qin Feng shouted excitedly on the radio: "Five hundred meters altitude, the growth rate is one thousand and one, the body is normal, please increase the altitude!" ”

"Yes, stay safe!"

The slender man of the J-8 fighter plane climbed high again, and began to dive down from a height of 800 meters, and its appearance was like an eagle swooping down from the sky to catch its prey.

Qin Feng felt that his body was starting to tremble.

His body was shaking with the fuselage, the muscles on his face were shaking, the lever in his hand was shaking, and the dashboard in front of him was shaking, almost making him unable to see the readings on the dashboard.

"Report, the fuselage is shaking, and it's still acceptable." Qin Feng shouted over the radio.

As the speed increases, the fuselage will shake, including the flat tail and the vertical tail are shaking, and if the plane can't accept this shaking, it will disintegrate in the air! Qin Feng's body will also disintegrate.

At this time, Qin Feng felt that all his internal organs began to protest, and he felt a faint pain, but he knew that this opportunity was also the best opportunity to test the performance of the fighter's body, and he must not give it up!

Keep it on!

The scenery outside shook, and when Qin Feng leveled the plane, he only saw that the instrument was approaching one thousand two, and the height was still not enough!

"006 reports, not reaching the required speed, requests a dive from a thousand meters." Qin Feng said.

At this time, the fighter plane had automatically raised its head and flew again, and after the speed slowed down, Qin Feng's body stopped shaking, he felt that his body was about to fall apart, and he really wanted to lean on the seat and sleep like this, but he knew that he must not stop, and he had to continue flying!

"006, can you bear it?"

"I'm fine."

"Okay, then dive from a thousand meters."

Test flights abroad, that is from an altitude of 10,000 meters, I only dive from a thousand meters, if I can't bear this, then what kind of test pilot!

Qin Feng took a deep breath in the air for a thousand meters, rubbed his aching arm, and then began to accelerate and dive again!

The shaking continued to occur, as the altitude became lower and lower, the speed became larger and larger, the shaking became more and more powerful, at this time, Qin Feng could clearly feel the frequency of his muscles beating, as if it had reached the natural frequency of his body.

Will he die in this test flight?

The brain was also shaking, quickly shaking away this idea, Qin Feng had only one thought in his heart, fly, if you can't fly at a predetermined speed, then I will fly down from a higher sky!

Only after all the subjects have been flown can an aircraft be officially completed and the test flight can be finalized and equipped with troops, and unqualified fighters must not be handed over to the troops!

The roar of the engine came from behind, and he continued to turn on the afterburner, pushing the fighter to accelerate, accelerate!

Suddenly, a white mist appeared in the nose of the aircraft, and this gas became larger and larger, spreading in both sides of the nose, becoming an umbrella-like shape, and then the nose of the aircraft jerked forward, piercing the top of the umbrella!

At this moment, Qin Feng felt that the entire cabin suddenly fell silent, and the roaring noise of the engine disappeared.

Qin Feng was overjoyed in his heart, he knew that he had already passed the sound barrier, had already flown to supersonic speed, and left the sound behind!

At the same time, the shaking of the fuselage was actually reduced, and he looked at the dashboard in front of him, which had just reached one thousand two! No, it's more than 1,002, it's supersound, have you flown enough?
