"Qin Feng, you are really a Qin Daring!" After hearing Song Lao's statement, Zhou Lao, the chief pilot of the test pilot, couldn't help but say to Qin Feng.

Do you do that? That's too bold, isn't it? However, if it is properly arranged, it shouldn't be too much of a problem, right?

Well, just to be on the safe side, at the end of the runway, put another bunch of old tires!

Qin Feng would never know that his title of Qin Daring had spread like this, if you want to test fly, you have to be scientific, and you have to have guts, and Qin Feng's guts are the biggest.

In order to be able to catch up with this good time without crosswinds, after careful consideration, Qin Feng's suggestion was adopted.

Removing the brakes is actually very simple, as long as you remove the brake pads inside.

Domestic technology is still backward in many aspects, Qin Feng remembers very clearly, more than ten years ago when he went to test the Mirage 2000, people used special ceramic brake pads, so that the plane can stop by braking, without additional devices such as parachutes, and after the braking is over, there is no high temperature.

Now J-10 has also developed a similar brake pad, although it can play the role of emergency braking, but, wear resistance, thermal decay performance, etc., can not be compared with similar devices in the West, and now it is only to solve the problem of whether there is or not, and so on to continue to improve performance, but also wait for the future technology accumulation.

Now, the brake pads have been removed, leaving only the bare brake discs, and this fighter has no brakes.

A car, without brakes, dare to drive? Of course it is impossible, but what about airplanes?

Airplanes are still possible, because airplanes have special deceleration measures!

Qin Feng got on the plane, he didn't hesitate, he had to ensure safety, after all, this plane was also expensive, if it was broken by a taxi, it would definitely be worth the loss.

Starting the engine and contacting the command platform, Qin Feng slid off the runway and began to accelerate again.

Twenty, forty, sixty, eighty, one hundred!

When the speed reaches 100, you can also see that the plane is still firmly facing the runway centerline, so there is no problem with the aerodynamic layout, landing gear position, etc., just the brakes!

Stop it!

Qin Feng turned off the engine, and then, skillfully put down the speed brake and parachute.

Behind the tail of the hanging tail, an umbrella flower suddenly popped up, this umbrella flower held the wind, swaying back and forth, floating non-stop, this is a speed of 100 kilometers per hour, just rely on the deceleration umbrella to stop it!

The plane continued to rush forward, and everyone raised their hearts to their throats, watching the fighter rush forward, for fear that they would finally rush off the runway and damage the landing gear.

Turn on the airbrake!

Not enough?

Qin Feng pushed the lever and began to operate the rudder surface on the fighter for the first time!

I saw the canard wings in front of the J-10 flipped downward, from a horizontal state to a vertical state!

When needed, the canard wing can also be used as a speed brake, the canard wing of the J-10 has a great effect, it can be used to generate vortices, improve the lift of the wing behind, can be used as a control surface, directly pry up the nose, when needed, it can also be used as a speed brake!

Superimposed on the strength of the canard wings, finally, the furious J-10 fighter was tamed, the speed became smaller and smaller, smaller and smaller, and when it was still a hundred meters away from the end of the runway, it was as slow as a human walking.

Stopped!

"Quick, tire baffle!"

"Parachute, parachute!" When the speed of the aircraft is reduced, the parachute will be automatically discarded, otherwise once the parachute falls, it may be just covered on the engine and burned, the parachute must be reused, this kind of thing is not disposable, it can't be wasted, after each parachute is used up, there will be a special ground staff to put it away and fold it again.

Qin Feng was also in a cold sweat on the plane, the deceleration parachute was discarded too early, he had already turned off the engine, but the deceleration parachute was cut off early, if he stayed for a while, he wouldn't need canard wings.

Everyone is doing it with all their hands, there is excitement and disappointment on their faces, and the excitement is that the reason has finally been found, it is on the brakes, and the disappointment is that the reason is not easy to find!

"Contact the comrades of the 609 Institute immediately!" Song Lao said.

The research and development of Jian-10 is a systematic project, Song Lao proposed the system of chief engineer for the first time, and all the financial power is in the hands of Song Lao, such a scientific research institute has committed a lot of crimes, they have been accustomed to taking money first and then doing things, and then applying for a routine when the money runs out, Song Lao broke this system at once, so the gossip is endless.

However, Song Lao is determined, this system must be adhered to, and, under this system, there are also many advanced units, 609 is one of them, they are responsible for the research and development of the landing gear part of the J-10, after giving up the program of spending high prices to import, self-reliance, and finally the landing gear to be processed, and the anti-skid system of the brakes on the landing gear is also from their hands.

They count as a subordinate contractor.

Now, this part has a problem, naturally solved by 609, this fault is not solved, then the follow-up can not be carried out, who would have thought that a simple braking system will also become a roadblock to the release of J-10!

Director Wang of the 609 Institute and technicians soon came, they lived in Chengdu for a few months, this problem is not simple, anti-skid system, is computer controlled, is also a popular means in the world, the current braking system on both sides of the torque is unbalanced, because of the software problems, the software to detect the tire has idling caused, but how to modify, we have no experience.

Modified again and again, experimented again and again, before and after, Qin Feng skated on this plane dozens of times, and even did not let go of the New Year's time, and finally, gliding at medium speed, you can slide in a straight line!

The difficulty of developing a new fighter is quite high, and after the improvement of this small fault, everyone is exhausted, and in the future, it will be necessary to release it, and it will be tested and finalized, and how many difficulties will be overcome!

The impurities during the engine test flight damaged the blades, and now the sliding and running deviation are already two roadblocks, and after these two roadblocks are solved, everyone is still full of excitement.

"Medium-speed skating, we're finally over, let's make persistent efforts and run at high speed!" Song Lao said firmly.

"Yes, it's our turn to run at high speed, but there is still a problem waiting for us when it comes to running at high speed!" Zhou Lao, the chief pilot of the test pilot, said: "Our runway is not long enough. ”

What the? The runway is not long enough? How is this possible? Qin Feng also wondered, is this still a problem?
