At present, no fighter has the ability to stall in this way, only the Su-27 has it, so when the Su-27 appeared at the Paris Air Show, this maneuver frightened everyone, such a situation only happened when the MiG-25 first appeared, when the MiG-25 flew over Red Square during the military parade, which frightened the entire Western world, they could not believe that there would be such a terrible fighter, moreover, it was a fighter!

The American SR71 can also fly to the double three indicators, but it is only a reconnaissance aircraft, it is impossible to make a large overload maneuver of fighters, at that time, the Western world trembled, trembling under this kind of aircraft, until later, Belenko defected, people found out that this so-called double three fighter, in fact, is made of stainless steel, this time there is no fear at the beginning.

Now, the Su-27 has once again brought shock to the Western world, and the performance of this fighter has shocked them incomparably! This kind of maneuverability, which is real, shows that this kind of aircraft has first-class performance in close combat, and even the F-15, which the Americans are most proud of, has to bow its noble head in front of it.

This will not be until later, with the continuous emergence of vector propulsion engines, all kinds of overstall maneuvers will gradually develop, even if it is even J-10, after replacing the vector engine, it can also make this kind of air cobra, and overstall maneuvers such as falling leaves.

As for now, the Su-27 is definitely the king in this field!

Of course, the appearance of this action is actually Pugachev's exchange for skill and adventure.

In 1988, Pugachev undertook the Su-27 extreme high angle of attack test flight mission, the danger level of this test flight is quite high, when the angle of attack of the aircraft is high to a certain Chengdu, the wing will stall, after the stall will tail spin, once it can not be changed out of the crash.

Pugachev bravely met this challenge, constantly breaking through the limit of the large angle of attack, until in a test flight, the engine stalled at an altitude of 15,000 meters, the plane height dropped rapidly, seeing that the situation was dangerous, Pugachev was ordered to eject and parachute, but as a test pilot, Pugachev in the last time, still tried his best to save his plane, went through hardships and dangers, and finally at an altitude of 800 meters, Pugachev restarted the engine, leveled the fighter and pulled up to climb, I thought that the danger period had passed, but who would have thought that when he was climbing the lever, he found that the angle of attack limiter forgot to turn off, and as a result, the nose did not stop at the expected angle, but rose all the way until it exceeded the 120 degree angle of attack, and after he released the lever, he actually leveled himself!

After Pugachev returned, he repeatedly thought about this phenomenon, calculated, and finally invented this set of cobra maneuvers, which won a sensational effect.

Now, Pugachev has won the cheers of everyone present by doing this action, and this action, in their eyes, is quite exciting.

"In air combat, this maneuver can put the enemy planes chasing behind you in front of you at once, turning passivity into initiative!" Said an Air Force officer.

When he heard his words, Qin Feng couldn't help but shake his head, and General Lin beside him saw Qin Feng's appearance and said, "What, are you dissatisfied with this action?" ”

Where can I be dissatisfied, I myself am still very envious, but if you want to talk about the role of this action in air combat, Qin Feng is really undeniable.

Can this action really turn passive into active?

Qin Feng didn't think it was possible, in modern air combat, energy is the most important! The fighter mafia has long explained this point of view, in battle, the energy of the fighter is the most important, a fighter without energy, that is, a live target, any fighter in the maneuver, is to be able to have more speed, greater height.

What now? This cobra maneuvers, but it has to consume energy, in this way, all the energy that it has easily accumulated is consumed, which is simply against the norm.

Without energy, the fighter is a target in the air, even if the opponent is given to the front, what is the use? The fighter in front can quickly turn sideways to get rid of it, and the fighter in the back simply cannot continue to chase and hover, because he has no energy!

It's deadly, and without energy, what's the use? It can only be beaten, so when the Pugachev Cobra maneuver appeared at the Paris Air Show, the theory of this maneuver has aroused a lot of controversy, some people think that this maneuver is useless, and will make the Su-27 a target in the air, and some people think that the maneuver can make the Su-27 get a fantastic nose pointing ability in a dog fight and seize the opportunity.

So, who has a point? Only actual combat can be tested, and in actual combat, can this action be made? Qin Feng is also skeptical about this, the simplest is now without any plug-in, if there is a missile, then, can the fighter do this action? You must know that the bearing capacity of the wing is limited, and after the plug-in, the wing can do this kind of action, it is not guaranteed!

If you can't do it with a missile, then what's the point of this action?

However, this maneuver can at least show that the Su-27 aircraft has excellent pitch control authority, high angle of attack stability, and anti-surge performance of the engine and air intake.

In that case, the two engines at the tail are still working stably, which is enough to show that the performance of this engine is strong, and this mature engine is also in urgent need of China.

This action may not be able to be done in actual combat, but, even if there is no such action, other ordinary actions can also fly more beautifully, after all, although there are more and more over-the-horizon air combat, but, combat in air combat is absolutely inevitable, and having an aircraft with advanced combat effectiveness is undoubtedly the most blood-pumping.

In the face of this action, Qin Feng is still looking forward to it, after all, this aircraft can do actions that other aircraft can't do, which shows that this aircraft is very maneuverable, and it has a modern and advanced aircraft, which is what everyone is looking forward to the most.

The current aircraft in China, the maneuverability is not comparable to it at all, Qin Feng tried his best to calm his mood, and continued to watch the flight performance of the Su-27 fighter, the cobra in the air is definitely the finale, but it is not the last, the other performances are also wonderful.
