"Damn it, why did you fly to Japan all at once?" Yang Yiwei quickly turned around and flew back. When the Japanese side saw the other party leaving tactfully, they did not move too much. After all, it is normal for planes to fly across national borders in the sky and other things. No one can see the national boundary on the ground at high altitude. As long as they inform them of their identity and purpose, they can basically travel from airspace.

Yang Yiwei flew back to his airspace at a speed of up to Mach 30. This was the first time that Yang Yiwei drove such a fast aircraft, excitedly making various flight actions in the air, hovering, diving, rolling, jumping, and turning sharply... All kinds of actions were operated without any pressure, and there was no sense of power that ordinary fighter planes could not feel from the heart. After doing some basic actions, Yang Yiwei wanted to do some complex high-altitude actions, allowing the slope to hover (large slope to hover), half rolling and inverting, half-pound bucket, half-pound bucket flip, inclined pound bucket... A set of complex movements to do the bottom lane made Yang Yiwei even more excited. The performance was too excellent and there was no difficulty at all!

After licking his lips, Yang Yiwei wanted to try some legendary actions. These actions can only be made by several countries with the most powerful aviation power at the most famous air show in the world. They can only be made by the best fighter jets with the best pilots and the best fighter jets after long training. These actions are only made by pilots in the United States, Britain, Russia and France, namely, the 'Pugachev Cobra maneuver', the 'tail rush', the British Harrier aircraft', and the Herbst "punching the wall" maneuver.

Pugachev Cobra maneuver: The aircraft maintains a speed of about 400KM for a flat flight. The key is that if the speed exceeds 420KM, the flight trajectory will not be maintained. After the nose is pulled up, the aircraft will climb. If it is too low, it will cause insufficient upward moment. The pilot closes the angle of attack limiter and pulls the rod back to the end. Since the force reaction is lagging after the rudder of the Su27 is deflected, the force reaction must be maintained for a short time. After the nose is raised to 60-70 degrees, the flat tail effect will completely disappear, becoming part of the resistance torque formed by the aerodynamics and center of gravity of the aircraft wing. This torque will continue to increase with the increase of the angle of attack. In turn, the upward momentum of the aircraft gradually decreases. The upward momentum moment completely disappears at the maximum elevation angle. The resistance torque becomes the recovery torque. The aircraft

Forward leveling. At this time, the pilot's technology will be very important. He must accurately master the flight trajectory of the throttle control aircraft. So that the Su27 can continue to maintain a "beautiful" flight route. At this time, the pilot's hand holding the rod is basically useless, whether it is a push rod or a pull rod. The aircraft will continue to be restored to leveling. Its properties can be determined as a continuous reaction to rough tie rod operation at a relatively small speed. At an angle of attack above 45 degrees, the pilot basically has no control over the aircraft. However, when the aircraft is at an angle of 110 degrees, the aircraft is forced to level up due to the disappearance of the upward momentum moment, which can expand people's thinking. That is, if enough upward momentum can be continued at this time, the aircraft will likely continue to lean back until the complete circular motion is completed, and this mission is finally completed by Su37.

In history, only Russian super-class pilot Pugachev has completed this set of actions in a complete flight of Su-37 fighter, and is recognized as a sexual action of Mount Everest during aviation flights!

Yang Yiwei quietly adjusted his mentality. As soon as he opened his eyes, his subordinates quickly controlled it. The entire fighter plane turned into a fast-moving cobra. He suddenly found that he was like a target and drew a huge aggressive action in the sky. This action was a huge cobra!

"Yeah!" After Yang Yiwei made the move, he couldn't help calling out excitedly. He didn't expect that he would have the opportunity to complete the Pugachev Cobra maneuver in his life. It was so exciting. If this was to be written into history, he should be the first person in China to do Pugachev Cobra maneuver!

"Next, tail rush!" Yang Yiwei took the Buddha as if he had taken stimulant, without any sense of fatigue caused by the difficult flight. He quickly adjusted the fighter, and the description of tail rush in the textbook appeared in his mind.

As the name suggests, the tail of the aircraft means rushing in front. Of course, no one thinks it is an aircraft whose tail can fly in front. The process is: after the aircraft accumulates enough speed, pulls up the head and jumps into a jump, but at the same time, the engine is artificially in a slow state, so that the thrust-weight ratio of the aircraft is less than one. Due to the effect of the earth's gravity, the speed of the aircraft continues to decline. When the airspeed of the aircraft is zero, the aircraft keeps the nose continues to rise, the tail is facing down, and "rush" down at an acceleration rate. The dynamic pressure of the aircraft is very small, almost falling under the action of gravity. It seems that the tail is rushing forward, so it is called "tail impulse". The air intake of the aircraft also becomes autonomously inhaled. The aircraft engine must adopt some auxiliary

Assistive measures, such as opening the auxiliary intake valve, continuously ignite the engine, etc., to prevent the engine from being shut down. After the aircraft descends for a distance, the fuselage leans forward and enters a dive state, and finally change it with a flat flight. To prevent tilt, the aircraft must maintain a symmetrical drop without side slip. Because the tail of the aircraft is in front, the aerodynamics of the flat tail will change from negative lift to positive lift, thus generating a torque that causes the nose to fall down, forcing the aircraft to enter a flat flight or dive. The success and beauty of this action depend largely on the performance of the aircraft and the skills and courage of the pilot. That is, the aircraft must not be sly during the descent. The more the speed of entering, the lower the high point, and the better the viewing effect on the ground.

The Dragon 30 fighter jet flying by Yang Yiwei was very fast. In order to prevent accidents caused by too fast speed, he reduced his speed to about Mach 15 for safety reasons. Then he suddenly pulled up the head straight and released the rocket launched by the Buddha. Then his tail turned off and turned off the engine. The plane then released the launch rocket played backwards, as if the tail was flying downwards. Seeing the altitude drop sharply, Yang Yiwei quickly turned into phantoms with his hands. The fighter ignited instantly, and the engine turned into a phantom and resumed normal flight.

"yes!" Yang Yiwei clenched his fist tightly. In fact, the most test of tail impulse is not the pilot's level, but more tests the performance of the fighter, instantaneous shutdown and instant start, "Perfect! Very perfect!"

If the previous two actions are often used to praise and test the fighter jets during the air show flights and test the pilot level, the "bookshelf" maneuver of the British Harrier aircraft and the "blocking" maneuver of the Hebster aircraft are very practical actions in air combat. In air combat, they can often achieve very obvious advantages and decisive victory.

The "bookshelf" of the British Harrier aircraft is maneuvered. Using the steering thrust of the Pegasus engine, the fuselage can be translated and suddenly raised while the vertical axis of the aircraft is basically maintained in the original direction. Looking from the front, the aircraft is like a "bookshelf" shape drawn on the blue sky. In the Battle of the British and Ama Islands, the British Navy lured the Ama Air Force into the air combat mode that it was good at. Using this special unconventional maneuver power of the Sea Harrier and the advanced AIM-9L missile that could attack at the time successfully dominated the air supremacy over the Horse Island. Unlike Russia's famous movement of maneuvering in the same one-sided plane, the maneuver range of British aircraft directly spans vertical or horizontal planes. It is very easy to fall off the opponent and track or lock the opponent. At the same time, the pointing point of the attack can be easily aimed at the opponent, and the enemy can fire first and take the initiative.

Herbst "punching the wall" maneuver: After the aircraft enters high-speed flight, it pulls the aircraft to an angle of attack of about 70 degrees (note: controllable state) and uses vector thrust to change the thrust direction, and at the same time uses the corresponding fuselage wing surface to control the aircraft to half-roll, quickly turn to 180 degrees, and then the push rod reduces the angle of attack to accelerate to the initial high speed. This action overcomes the past problems of increasing overload and requiring a large hover distance. The entire action is like a swimmer pedaling the wall and flips around the pool wall, so it is named. Since its maneuvering radius is only 17.5% of the normal hover radius, it greatly improves the agility of the aircraft. It plays a very important role in air combat.

Yang Yiwei silently muttered in his heart that he had written in the textbook. There was no trace of relaxation in his hand. He continued to do a series of movements. The fighter suddenly pulled up vertically in the sky and then immediately moved to the right in an instant, then translated to the left. After several consecutive shifts, Yang Yiwei took a breath, calmed down his excitement, slowly pulled the plane up to 70 degrees, then stepped on the accelerator, accelerated instantly, and then pulled the rod quickly. The plane seemed to be a swimmer who ran into a high-altitude carp on the edge, and then several carp on the turn.

"It's so good! I've been flying all my life, I've never had any pleasure today. I've done all the actions I've never done before, and I've done them several times in a row, each time more refreshing!" Yang Yiwei's face turned red because of excessive excitement and bloodshed!

Soon, Yang Yiwei, who was slowing down, flew over the airport under the navigation of the ground radar. He reduced his speed to the normal speed of the plane, and did the few movements he had just made very coherently and several more times, making the people waiting below stunned!

"Pugachev Cobra maneuver..."

"Tail rush"

"Herbst "punches the wall" and maneuver"

"British Harrier's "bookshelf" maneuver"

Among the people below, there were many people who knew the goods, and all the movements were recognized by people. Others had heard of these legends from books, and the people who knew the goods shouted loudly. No matter how stupid they were, they knew how powerful these movements were!

"Incredible! It's not really surprising that I can make these actions. What surprised me is that I can make these actions quickly and continuously in the air. It's incredible, incredible!" A lieutenant general from the Air Force used three incredibles to express his inner shock.

Soon, the fighter slowly reduced its speed and finally floated in the air, slowly reduced its height, opened the landing gear, and landed very smoothly on the ground without any slippage.
