Short take-off and landing is not for show, it is of practical use. Pen, fun, and www.biquge.info

In modern warfare, bombers are not needed, and the first round of ballistic missile strikes can be used to flatten the main airfields of the opposing side! Therefore, the problem faced by many fighters is that they need to take off on the runway after being bombed! In this way, the higher the ability to take off at short distances, the better!

This limit, of course, is that there is no need for vertical take-off and landing on the runway, for which Britain developed the Harrier aircraft, and the Soviet Union developed the Yak-38.

Therefore, short take-off and landing is a new requirement for fighters, the previous second-generation aircraft, all need a runway of thousands of meters, and the third-generation aircraft, this requirement is shortened to 500 meters, such as Su-27, under the air combat load, 450 meters of runway can take off.

But now, the Americans' plane, which took off at a distance of less than 200 meters, has to be said to amaze the audience!

Cruise piloted the fighter, although it flew, but the speed was not very high, so the next thing was to speed up! At this time, the afterburner of the tail engine is still fully open, and the tail nozzle is backwards, continuing to release majestic thrust, pushing the fighter to continue to accelerate and accelerate!

When the fighter disappeared from the sight of the audience on the ground, the tip of the nose of the nose appeared with the spike of a sonic boom cloud, and the F-15 had exceeded the speed of sound!

Next, it's time for the show!

The audience on the ground, wait and see, some of them holding binoculars, some of them blocking the sun's rays with their hands, looking in the sky.

Where did that show plane go? It can't be a trek, right? Do you still have to wait?

Not long after, about a minute, there was another roar in the distant sky.

One thousand meters in the air, the red and white fighter plane roared in, and in the front of the fighter, there was a white spike-like steam ball!

Damn it! Several spectators who were the first to see it with binoculars were instantly shocked, some of them stood up and wanted to run back, and some of them used their hands to block their ears tightly!

Are pilots crazy? Now this plane is still in a supersonic state!

Low-altitude supersonic speed is absolutely prohibited, on the one hand, because many aircraft cannot fly supersonic in the low-altitude dense atmosphere, and on the other hand, it is the supersonic flight of aircraft, which is simply a disaster for the ground! Not to mention, if this plane comes, all the glass of nearby buildings will have to be shattered by the power of the sonic boom cloud!

Are these Americans here to demolish the Moscow Air Show? Even so, you can't harm the audience, many of them are Westerners!

Flying at a supersonic speed of 1,000 meters in the air proves the strong engine performance of the F-15, and at the same time, it is also an extremely irresponsible behavior!

It's a pity that no matter how fast the people on the ground move, it is impossible to reach supersonic speed, and the performance machine is roaring!

Closer, closer! Almost less than three kilometers away from the audience, all the audience could see this performance machine with a white shock wave spike. There are some people who don't know why, they are still quite curious, very strange, they have seen the plane pull smoke, it should be behind the plane, now, does this plane have a smoke device in the nose?

In the sight of the people on the ground, I saw the F-15 fighter in the sky, which suddenly turned into slow motion.

Hey, that's weird, why is it slow?

What about that spiky vertebrae-like white gas on the top of the head? Why not? Lao Tzu just raised the camera!

What are the Americans doing?

Only those who are most familiar with fighter planes are all discolored on their faces, and this action of the Americans is a performance of sudden braking in the air!

That's right, it's a sudden braking in the air! Just as the plane came to the most suitable position for the crowd to watch, Cruise pressed the button and turned on the thrust reverser device on the tail of the fighter.

The thrust reverses the blade action, the airflow is blocked by the blades, and it is sprayed forward, and the thrust becomes resistance, which instantly makes the speed of the fighter drop rapidly! At the same time, the canard wings in front of the canard, which have also become vertical at this time, together with the tail speed brake, act as another device for deceleration.

The flight speed was Mach 1.2 just now, and now, it has been quickly reduced to Mach 0.7! Cruise felt his body tightly strangled by the seat belt, afraid that there was a mark, and his heart seemed to fly out of his chest!

Just now, it was overloaded with at least 6G! Is this air brake pretty?

Pretty bird! Standing on the tower and watching the plane roar coming, Andrei was full of contempt in his heart, this action, if it is done when landing, reducing the running distance by reverse thrust, this can still make the audience applaud, and now? Is it to brake sharply in the air, with birds? The theory of energy air warfare, that is what the Americans put forward! This kind of active deceleration is simply looking for death! Without speed, there is no ability to maneuver, can you be a live target?

Have all one's goods in the window! It's the same as your own cobra maneuver, but your cobra maneuver at least looks prettier and is easy to cheer, but now? What is the point of this sudden braking in the air?

"Not good!" At this moment, Andrei suddenly shouted loudly: "Quick, evacuate the audience!" Fire trucks, ambulances ready! ”

Paralyzed, he had already warned him to stay away from the audience, but he didn't listen, and he was playing some kind of air brakes, but now it's good, from the air intake, spewing flames!

The pilot's eyes made Andrei quickly see the American fighter plane in the distant sky, which was already extremely dangerous at this time! Forget it if you fall yourself, don't smash the audience below!

The thrust reverser device, which has been widely used on passenger aircraft, is to have an additional baffle in the back to push the jet air flow to the front, providing the torque of deceleration, and at the same time, it is also easy to achieve on passenger aircraft, because passenger aircraft are the layout of the engine hanging under the wings, and the engine does not need an air intake, and it is directly exposed.

And on the fighter, it is not so simple, the engine of the fighter is in the tail section, and the front needs the air intake, and the blades of the reverse thrust are in the middle of the engine, and as a result, for some reason, the air flow blocked back by the baffle jumps into the air intake!

This is an ordinary aluminum alloy, which can be melted at a temperature of several hundred degrees! And now, the blazing tail flame is rapidly melting the air intake! A flight show that was determined to be won turned into a performance accident! (To be continued.) )
