Red Soviet Union

Remember【】in a second, providing you with wonderful novels to read.

Short take-off and landing is not just for show, it has practical uses.

In modern warfare, bombers are not needed, and the first round of ballistic missile attacks can bombard the opponent's main airport! 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 of short takeoff, the better!

This limit, of course, is the vertical take-off and landing that does not require a runway. For this reason, the UK developed the Harrier aircraft, and the Soviet Union developed the Yak 38. However, vertical take-off consumes a lot of fuel, resulting in an extremely short combat radius of this aircraft. , lost the necessity of existence.

Therefore, short take-off and landing is a new requirement for fighter jets. The previous second-generation aircraft required a runway of a kilometer, while the third-generation aircraft shortened this requirement to 500 meters. Next, the 450-meter runway will be able to take off.

But now, the American plane has taken off at a distance of less than 200 meters, and it has to be said that it is amazing!

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

When the fighter plane disappeared from the sight of the audience on the ground, the front end of the nose appeared a sharp cone of a sonic boom cloud, and the F-15 had already exceeded the speed of sound!

Next, it's a wonderful performance!

Spectators on the ground, wait and see, some of them are holding binoculars, some are blocking the sunlight with their hands, searching in the sky.

Where did that performance plane fly to? Could it be lost? Do you still have to wait?

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

One thousand meters in the air, the red and white fighter plane roared towards it, and at the front of the fighter plane, there was a ball of steam like a white cone!

Damn it! The few spectators who were the first to see it with binoculars were shocked instantly. Some of them stood up and wanted to run back, while others blocked their ears tightly with both hands!

Are pilots crazy? Now this plane is still supersonic!

Supersonic speed at low altitudes is absolutely prohibited. On the one hand, many aircraft cannot fly at supersonic speeds in the dense atmosphere at low altitudes.

On the other hand, the plane flies at supersonic speed, which is a disaster for the ground! Among other things, if this plane comes over, the glass of all nearby buildings will be smashed under the power of the sonic boom cloud!

Are these funny Americans here to disrupt the Moscow Air Show? Even so, it can't harm the audience. Many audiences are Westerners!

Flying at a supersonic speed in the air of 1,000 meters proves the powerful 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, they can't reach supersonic speed. That performance machine roars in!

Closer, closer! Almost at a distance of less than three kilometers from the audience, all the audience can see this performance machine with a white shock wave tip. Some people who don't know why are still quite curious. It's very strange. I've seen an airplane pull smoke. It should be behind the airplane. Now, does this airplane have a smoke emitting device on the nose?

In the line of sight of the people on the ground, I saw the F-15 fighter plane in the sky, and suddenly it became a slow motion.

Hey, that's strange, why is the speed so slow?

What about the pointed white gas above the head? Why not? I just raised the camera!

What are Americans doing?

Only those who are most familiar with fighter planes change their faces. This action of the Americans is performing a sudden brake in the air!

Yes, it is the emergency brake in the air! Just as the plane was being set up and came to the most suitable position for the crowd to watch, Cruise pressed the button to activate the thrust reverser at the tail of the fighter.

The thrust reverses the action of the blades, the airflow is blocked by the blades and ejected forward, the thrust becomes resistance, and the speed of the fighter drops rapidly in an instant! At the same time, the canards in front also became vertical at this time, and together with the speed brake at the rear, they acted as another device for deceleration.

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

Just now, at least it has withstood the overload of 6G! Isn't this a sudden brake in the air?

Beautiful bird! Standing on the tower, watching the plane roaring towards, Andre was full of contempt in his heart. If this action is done when it is landing, the slide distance will be reduced by reverse thrust, which will still make the audience applaud. What now? It is to brake suddenly in the air, is it useful for birds? The theory of energy air combat was proposed by the Americans! This kind of active deceleration behavior is simply courting death! Without speed, there is no maneuverability, is it a living target?

Flashy! It's the same as our own cobra maneuver, but at least our own cobra maneuver looks more beautiful, which is easy to arouse applause, but now? What's the point of this sudden brake in the air?

Not good! At this moment, Andre suddenly shouted: Hurry up, evacuate the audience! Fire engines, ambulances are ready!

Paralyzed, he was warned a long time ago to stay away from the auditorium, but he didn't listen, and he was still playing with sudden brakes in the air, but now it's fine, flames are spurting out from the air intake!

The pilot's eyes made Andre quickly see the American fighter plane in the distant sky, which was extremely dangerous at this time! It's fine if you fall yourself, don't hit the audience below!

The thrust reverser device has been widely used on passenger planes, that is, there is an extra baffle at the back to push the ejected airflow to the front to provide deceleration torque. At the same time, it is also easy to implement on passenger planes, because passenger planes are all The layout of the engine hung under the wings, the engine does not need an air inlet, it is directly exposed.

On a fighter plane, it is not so simple. The engine of the fighter plane is at the rear, and the air inlet is needed in the front, and the thrust-reversing blades are opened in the middle of the engine. As a result, for some reason, the airflow blocked by the baffle, Jumped into the air intake!

Here is ordinary aluminum alloy, which can be melted at a temperature of several hundred degrees! And now, the fiery tail flame is rapidly melting the air intake! An air show that was determined to win turned into a performance accident! (To be continued.) Mobile phone users please browse and read for a better reading experience.
