Chapter 643: Insist on flying back
The canopy flew!
No one thought that there would be such an accident, and now, the situation is already obvious, it is definitely the mechanism of the cockpit canopy that has a problem, and the problem of cockpit loss of pressure has been found, but Qin Feng is facing a more dangerous situation!
The cockpit canopy and the entire cockpit formed a sealed pressurization mechanism, and now, the cockpit canopy above his head flew, and Qin Feng suddenly turned into an open-top plane.
Even if you sit in an open-top car, you can feel this kind of refreshment, when the car is fast, your hair can flutter in the wind, and this is only a hundred kilometers per hour, and now? The speed of a fighter plane is seven or eight times that of a car!
The airflow was quite powerful, when the cockpit canopy just fell, due to the problem of internal pressure, Qin Feng felt that he was about to be sucked out, and this feeling disappeared in two or three seconds, and then, the stronger airflow turned into a rushing face, blowing on his face, without the edge of the oxygen mask, and his eyes, it was as if he had been cut by a knife in an instant!
Think about the high-pressure water gun, it is a sharp weapon against the rioters, with the high-pressure water gun, you can directly wash people away, and now, this powerful air current, the pressure brought by it, is definitely stronger than the high-pressure water gun!
This is first of all due to the speed, the flight speed of the fighter is quite high, at such a large speed, the head-on air flow is extremely strong, and secondly, because of the aerodynamic shape of the aircraft, according to the Bernoulli equation, it is possible to calculate the wind speed and the pressure of the air flow.
It can be said that now Qin Feng is undergoing the test of death, and in this case, Qin Feng will even be sacrificed by a violent wind at any time!
The moment he felt the airflow, Qin Feng closed his eyes, as a pilot, he has a pair of sensitive eyes, now, he must also protect his eyes, in the airflow, his every movement is thrilling, he used all his strength, finally raised his left hand, and then, pushed the helmet, put down the goggles on the helmet.
The goggles are black, mainly for the role of sunglasses, when the pilot flies in the direction of the sun, you need to put down the goggles, and in normal times, the goggles are raised, of course, if it is an ejection escape, the goggles are also put down, which can slow down the impact of the airflow, which is also the only scene where it plays the role of goggles.
And now, the goggles have become goggles again.
The goggles are not tightly fitted with the oxygen mask, and now, the air flow comes in through the gap, even sharper, like a knife, the cold air cuts Qin Feng's face, however, the eyes are finally relaxed, Qin Feng slowly tries to open his eyes, and he can still see.
In the headphones, there was also the sound of whirring, and now, everything around him could not be heard, he could not hear the sound of the rear cabin, nor could he hear the sound of the ground.
The canopy is off! When I heard this voice, the ground tower, which had just been relaxed, became nervous again.
"001, report the situation, 001, report the situation."
Although the plane is very precious, but the pilot's life is even more precious, it is very important to fly the plane back and find the cause of the failure, but Qin Feng, as an excellent test pilot in China, if he has no choice but to parachute, it is completely okay.
Of course, everyone has another concern, has the current Qin Feng been ejected?
This time, the canopy was thrown off under abnormal circumstances, which also meant that the ejection system also failed.
In order to protect the pilot's life, the cockpit is necessary to have an ejection escape system, in short, it is just a few steps, the pilot puts his legs together with his hands, saving himself from hanging something to be torn off when he goes out, and then, pull the ejection handle between the legs, the cockpit canopy is thrown off, the flight seat under the pilot's butt has a rocket engine, ignition, take the seat, leave the cockpit, after reaching a certain height, the pilot and the seat are separated, the parachute on the pilot's back is opened, and the pilot can land.
There will be a lot of problems in this, any link is wrong, it may lead to ejection failure, MiG-21 is like this, because the ejection success rate is quite low, known as the pilot's coffin, so, the domestic J-7 fighter, only to improve the ejection mechanism, improve the success rate.
Even so, compared with the world's advanced technology, such as Martin Baker's ejection seat, the gap between their own side is also very large, the ejection envelope is limited, the speed is too low, too high, can not be ejected, and the height is too low, and the Western ejection seat has been able to achieve the most critical zero zero ejection, in the case of zero height and zero speed, it will also achieve successful ejection, so when Lao Ba buys the J-7, he must install the Martin Baker company's seat, there is a reason.
These have said a lot, in short, now that the cockpit canopy has been thrown away, then this ejection link has begun, and now, what about Qin Feng, has he already gone out?
The situation in the rear cabin was even better, at this time, Yang Lin was calling loudly into the radio, but the cold wind was blowing over, and this voice drowned out his calling voice, and on the ground, all he heard was the roar of the terrible wind.
What to do?
Qin Feng in front of him naturally knew these dangers, but he had no choice now, as long as he had a chance, he had to do his best a hundred points!
His body, slowly, slowly moving forward, with each movement, required a tremendous effort, and it took him almost all his strength to lean his body against the dashboard that was close at hand.
The strong airflow is reduced all of a sudden, and there is a block in front!
The front of the pilot, that is, the dashboard, the front of the dashboard, is a three-section windshield, these can block the air flow in front, just when Qin Feng was on the seat, he was pressed by the air flow and couldn't move, now, drill here, it is comfortable all of a sudden, like finding a shelter in the wind.
Of course, he is very dangerous now, if at this time, the ejection seat is activated, then at this moment, Qin Feng's spine will all be broken, and even if he can survive, he will not be able to move for the rest of his life.
No matter how risky it is, he won't give up!
Now, Qin Feng was panting and accumulating strength, he had to continue to fly and fly back! Only by flying back can we find the ultimate cause, otherwise, we will have to risk repeating it next time, and the signs of the accident will always exist!
This is the mission of test pilots!
