Chapter 678: Thrilling
"Bang, bang!" In the high wind, the sound of the tire popping is still very clear.
At the moment when the wheels touched the ground, the main landing gear and the four tires all burst under the violent impact!
The tires of the fighter are specially made, the same as the tires of the car, it has no inner tube, the outer tire and the rim are tightly combined to keep it sealed, however, compared with the tires of the car, it has a special tire structure with double tread, and two layers of special cords are added to the inside of the tire tread rubber, called "reinforcing cord layer". With the ply layer as the boundary, the tread rubber is divided into the outer layer of tread rubber and the inner layer of tread rubber, and when the tire is worn to expose the second layer of particle, it will be scrapped. (Looking at it this way, it's very similar to a retreaded tire, but of course, it can't be refurbished.) The rubber surface of the aircraft tire is made of wear-resistant and high-temperature resistant special material glued steel wire, about 20 mm thick, and the strength is very high, after all, the use environment of the aircraft tire is very harsh, when it is in the sky, it may have to withstand the severe cold of dozens of degrees below zero, and after the moment, the moment of contact with the ground, it will be the same as the aircraft, running forward at a speed of more than 300 kilometers per hour, and when the big guy of the aircraft is in contact with the ground, it has to be impacted, which requires the tires of the aircraft to be high-strength.
Even such tires now can't withstand such a violent impact, and the tires all burst out!
Ordinary fighters may be two-wheeled in the front, but the main landing gear in the rear is generally single-wheeled, but the J-7 is different, as a heavy fighter-bomber, it weighs more, so it uses two-wheeled.
Now, the tires have burst and are rushing forward on the track, and at the same time, they are bumping up and down, which is the same feeling as a car tire bursting, but think about bursting a tire at 300 kilometers per hour, it is a matter of life and death.
The danger is not over!
Qin Feng heard the sound of a flat tire below, and knew that the situation was not good, and now, he had no other choice, he turned off the engine on the right side, and then shouted: "Put down the parachute!" ”
Yang Lin didn't panic, he believed in Qin Feng very much, as long as Qin Feng was there, there would be no problem, Yang Lin was waiting for Qin Feng's order, although it was still too early to put the parachute, but there was no way, the plane had to stop as soon as possible!
The tail of the J-7 pulled out a line, and the end of this line quickly bulged, and then it turned into a beautiful umbrella flower, relying on it to hold the air and the fighter plane that was running forward rapidly.
At this time, the landing gear in front of the J-7 has not yet been grounded, and the deceleration parachute is lowered at this speed, and when it is pulled in the back, in an instant, the nose of the aircraft is warped, Qin Feng has long expected it, and pushed the operating lever to the front to offset the moment of raising the head.
The moment the parachute was deployed, the fighter plane began to slow down rapidly, as if pulling the reins of a horse, but in the next second, this feeling disappeared again.
"Parachute breaks!" The ground shouted.
The release of the parachute is principled, and the speed can only be released when the speed is reduced, and if the speed is too fast, the umbrella surface of the parachute may break in the impact of high-speed air current.
This is the same as skydiving, or the return of spacecraft, when the speed is very high, first open a small umbrella, after slowing down, can open the main parachute, if you come up to open the main parachute, the umbrella surface is torn open by the wind.
Now, the parachute no longer works, and the parachute that was bulging in the back has fallen down and turned into a piece of cloth that has been dragged.
Fighter jets are fast like a shuttle.
The tires were still bumping up and down, deformed, and after dozens of turns, the tires were detached, and the rims were directly touching the ground, and then, everyone saw the sparks that were rubbed out, like grinding wheels.
"Fire truck, get on!" At this time, the plane couldn't wait to stop, and the fire truck with the flashing police lights had already rushed up at full speed.
Now, the only thing that makes everyone feel fortunate is that the fighter plane is still rushing forward, the state has not changed, and it is still aimed at the center line of the runway!
On the ground, deep traces were left, and when the wheel rim was crossed, it was like a tractor plowing it, and the concrete runway was actually cut open!
The fighter jets were jolting up and down even more.
If the friction continues, once the rim is deformed and disintegrated, the hydraulic rod of the landing gear will be left to rub against the ground, and the test flight will make the aircraft even more dangerous.
The front landing gear landed.
The tires in front did not explode, they were rotating steadily, and Qin Feng relaxed at this moment.
He has done his best, he has done everything he can, and now, he can't do anything, he can only wait.
Although pedaling with both feet is a brake, however, Qin Feng will definitely not dare to pedal down now, if he steps down, the rim below will definitely be deformed.
What is the speed now? It's been reduced to less than a hundred, right?
The scenery on both sides was getting slower and slower, slower and slower, and when it reached the end of the runway, the fighter plane finally stopped moving.
Qin Feng's back was soaked again, and even, he felt that the inside of the cockpit was starting to fog, and the sweat on his forehead fell drop by drop, Qin Feng took off the oxygen mask and exhaled heavily.
"Yang Lin, are you afraid?" Qin Feng asked to the rear cabin.
"Well, I said I'm not afraid, do you believe it?" At this time, Yang Lin could still be humorous: "I must be a little afraid, but as long as I think of you in front, I am very relieved." ”
The most reassuring thing for Yang Lin is Qin Feng, as long as Qin Feng is flying, Yang Lin will not be afraid, which makes Qin Feng feel more pressure, yes, this is a two-seater aircraft, he is not only adventuring alone, but also has a companion, if he can't save the day, then he will be heroic with his companion.
The risk encountered this time was something I had never seen before, the plane had no rudder, and then, when landing, all the tires were blown off, and the parachute was torn.
"Look at the missiles on both sides, are they still there?" Qin Feng asked again.
This time, it is flying with bombs, and there are still four missiles hanging on both sides, is there a problem with the missiles when the impact is so powerful?
"Gotta wait, I don't have the strength to turn my head now." Yang Lin said in the back.
Just came down together, maybe they didn't feel anything, but now that everything is over, Yang Lin feels that he has no strength in his body.
At this time, the fire truck had already arrived next to them, fortunately, there was no fire, and the ground crew on the fire truck had already run towards them.
