The landing gear in front also touched the ground, and if you put it at this time, the effect is already poor.

Qin Feng's mouth couldn't help but open wide, he saw the nose of the plane suddenly paused forward, this was the other party stepping on the brakes!

Now the speed is more than 200, right? At this time, when you step on the brakes, are you not afraid of breaking the brake pads?

The pilot's operation is very simple, not to mention all kinds of complex buttons, mainly three control mechanisms, the left hand is the throttle lever, which controls the power of the engine, and between the legs is the right-hand control lever, which can be operated front and back, left and right, and control the roll and pitch of the aircraft.

There are two rudders on both sides of the foot, in the sky, with the pusher to complete the steering, on the ground, the two feet together is the brake.

If Qin Feng is allowed to fly, the main landing gear will release the parachute after touching the ground, and will not step on the brakes until the speed drops down and is below a hundred, but the other party will directly step on the brakes at this speed?

Impossible, how is this possible? The brake pads will then turn red and even detonate the tires due to the heat! How could the test pilot of the opposing side make such a low-level mistake?

Qin Feng watched the fighter plane in the brakes, and the speed was rapidly reduced, and the naked eye could see that the brake pads were slightly red, this is simply a serious violation of flight regulations, right? The other party is an experienced veteran pilot, how can he do this?

So Qin Feng couldn't hold back any longer, and said, "No, I'm going to go and see first!" ”

It was not far from the tarmac, and when Qin Feng ran over, the Phantom 2000 had already stopped steadily, and the ground crew was carrying the ladder over.

The hatch of the fighter plane slowly opened, and Bill shouted inside, and then the roar of the engine died down.

Taking advantage of this opportunity, Qin Feng had already skillfully approached this Mirage 2000 fighter from the side.

It is very dangerous to be next to an airplane, and if the engine of the airplane is started, people are close to the air intake, and it is easy to suck people in, and such tragedies have happened before.

Qin Feng knew that it was presumptuous to do so, but he was so surprised now, he bent down and got under the wing, slowly stretched out his hand, and used his fingers to get close to the brake pads on the wheels of the main landing gear.

The main principle of braking is friction, which takes away kinetic energy by friction and heat, so as long as it is braked, the brake pads will heat up.

If it is a car, on the long downhill road, it is not uncommon for the brakes to catch fire because of heat, and the common way for truck drivers is to water the brake pads to cool the brakes, so in the summer, the truck downhill can see white gas in the tires, which is the friction of the brake pads to generate heat and evaporate water vapor.

For fighters, the speed when it comes into contact with the ground is two or three hundred kilometers per hour, and when braking at this time, how high should the temperature of the brake pads be?

Qin Feng couldn't imagine it, his hand slowly approached the brake pads, if it was a brake like J-7, his hands would not dare to touch the brake pads, it would make the flesh on his fingers instantly burned.

At the same time, ordinary people use their fingers to cover things, but Qin Feng uses them the other way around, according to the nerve reflex, once it is too hot, the fingers will curl up, so that if they are used in reverse, they can just leave.

Now, when Qin Feng's hand slowly approached the brake pads, he couldn't feel the temperature, and finally, his fingers lightly touched the brake pads, and he only felt some temperature on them, but it was definitely not the kind of hot temperature, only more than twenty degrees higher than the air temperature, which was about the same as body temperature.

How can it be?

After Qin Feng found that it was not hot, he simply stroked the brake disc with his hands, and went around in a circle like this, touching it, all of them were warm feelings, but there were some black marks on his fingers.

After touching this side and then touching the other side, when Qin Feng came out, he looked at the black marks on his fingers in the sunlight and said, "What kind of material is this?" ”

"It's a graphite-based composite." At this moment, a voice came from his ears, this voice was speaking French, so Qin Feng didn't know what the other party was talking about now, he should have introduced himself, right?

When Qin Feng raised his head, he saw an old man.

That's right, this is an old man, the years have left wrinkles on his face, his stature is not high, he is slightly fat, and his forehead is bald.

Although he was not young, he was still full of energy, and he looked at Qin Feng, a guest from the east, with a smile on his face as he was shocked by the brake pads of his fighter plane.

Just then, everyone else arrived.

Boileau approached him and almost shouted, "Old Mr. Dassault, why are you here?" It's noisy here and it's not good for your body. ”

Mr. Dassault? When the translator of the peer told everyone, everyone was suddenly surprised.

This old man is the helmsman of Dassault.

Born in Paris, France in 1892, Marcel Dassault graduated in 1913 from the fledgling École Supérieure de Aeronautics, where he worked as a propeller designer.

The two world wars brought him opportunities and disasters, and in World War II, he was imprisoned in a concentration camp because he refused to cooperate with **. After many twists and turns, after World War II, the company led by Dassault developed rapidly.

Starting with the MD.315 "Flamingo" twin-engine light transport aircraft and trainer aircraft, Dassault has successively developed the "Hurricane" fighter-bomber, the "Mysterious" fighter, the "Mysterious" B2 fighter, Europe's first "Super Mysterious" fighter that exceeds the speed of sound in level flight, the "Military Flag" and "Super Military Flag" carrier-based attack aircraft, as well as the famous "Mirage" series of fighters, as well as the "Falcon" executive aircraft.

And now, although he is nearly 90 years old, his body is still strong, he is still on the front line of aircraft design, and the project of Mirage 2000 is also soaked in his sweat and hope.

Who would have thought that he would come to the scene of the air show today!

General Lin and the others were also in awe.

Patriotism knows no race, every upright person will love their country, and Dassault Sr. is still fighting for the French sky at this age, and he is also the most respectable person.

Dassault Sr. had a smile on his face.

The Mirage 2000 fighter is a new generation of Dassault fighters, in the design, he began to consider the way out of this fighter, and now, when the Chinese guests come here to investigate, he can't help but come to see, want to impress the other party with the excellent performance of his own fighter.

If the Mirage 2000 fighter can be exported to the East, it will be a huge profit growth point for Dassault.

"We have also gone through many years of research and development on the brake system of the fighter, and now we use the latest carbon/carbon composite brake pads. This material has a series of advantages such as high temperature resistance, corrosion resistance, good chemical stability, low coefficient of thermal expansion, good thermal shock resistance and is not prone to sudden catastrophic damage, and now it has been extended to brake pads, including the brake system of space shuttles, military and civil aircraft. ”
