In the past, there were various flight performances on their side, the most commonly used is the J-7, the lowest speed of this aircraft is large, and the turning radius is large, so after completing a performance, it flies out from the audience's field of vision, but the third-generation aircraft is different, the turning radius is small, and almost the entire flight show is done in front of the audience, which looks quite chic and beautiful, such as now.

After completing the tail rush action, it is circling and descending, watching it go around such a small radius, everyone is thinking in their hearts, if they fight with this kind of fighter, there is no hope of victory at all, because people turn in circles too fast, and if they turn half a circle, they can turn around, so they watch people disappear in their front hemisphere, and then fly to their back hemisphere and launch a strike, and they have no way to prevent this situation. I can only watch myself being rounded by the other party behind my ass.

When it circled and descended to almost the ground, the plane changed, it stopped spinning, but it still maintained the position of the nose upward, and just like that, passing in front of the audience, like a duck, quacking past, the roar of the engine stimulated everyone's eardrums, and the shock in front of them was something that no one could forget.

The high angle of attack is a way to greet the audience and a way to show the maneuverability of the aircraft.

The angle of attack is the angle between the relative airflow direction and the wing's wingstring, which is generally positive when the aircraft looks up. The flight of the aircraft needs the angle of attack, because this angle of attack can make the wing and belly of the aircraft obtain lift, especially this kind of large side wing aircraft, the whole body is a whole aircraft, can provide lift, but it, although the angle of attack can provide lift, but the drag force is also increasing, with the increase of the angle of attack, the linear shape of the resistance increases, and the lift force is attenuated, so that there is a critical value, when it increases to a certain angle of attack, the aircraft can not continue to fly normally, this is the critical angle of attack.

The critical angle of attack of the second-generation aircraft is very small, generally not more than thirty degrees, but on the third-generation aircraft, this angle of attack may exceed sixty, seventy degrees, and the current MiG-29 is flying at an angle of attack close to seventy degrees, moreover, its speed is not fast!

What's the use of that?

In the air show, this is a way of greeting, like kicking the rostrum in a military parade, and in the actual battle, this high angle of attack flight ability, can allow the aircraft to obtain better low-speed maneuvering ability and better handling stability, the most important performance of which is the aircraft's nose directivity, which is especially important in close combat.

In the past, the angle of rotation of the seeker was only a few degrees, so that the aircraft had to be firmly aimed at the tail of the enemy aircraft in order to get the opportunity to launch, but now, with the development of technology, the field of view of the missile's seeker is getting wider and wider, such as its own Thunderbolt-8 missile, the seeker has been able to reach 30 degrees, and it is said that now more advanced missiles can achieve 60 degrees.

What does this mean? In future air battles, the ability to continue hovering is no longer important, the ability to point instantaneously is the most important, operate the fighter, quickly turn around, as long as the missile's seeker can intercept the target, and then the missile can be launched!

It is also under this factor that the canard layout of the fighter design began to become popular, this design is to allow the aircraft to have a good nose pointing ability, instantly change direction.

Now, the layman looks at the excitement, the insider looks at the doorway, and the MiG-29 is using its performance to conquer customers from China.

The ability of large angle of attack is determined by many indicators, such as engine performance and residual lift of the wing surface, etc., MiG-29 as a third-generation aircraft, in close combat, is indeed a king.

After the high angle of attack passed, the fighter continued to make a small radius of the turn in front of it, and flew back again, and when it saw its movements, the crowd stood up.

Next action, side-to-side fly!

Flying sideways, that is, the body of the fighter is sideways, and the wings are vertical, this kind of action, most planes can do it, but it is not easy to fly sideways through the field.

At this time, the pilot inside skillfully pulled up the nose of the aircraft, opened the ailerons, loosened the aileron rod to hit the rudder while controlling the throttle to maintain the altitude, and the aircraft entered the sideways flight state.

This is the same as some car stunts, the car is sideways, only one side of the tire touches the ground to do a variety of performances, and the plane wants to fly sideways, it is not easy, only the fuselage side area is large enough, the power is enough, the center of gravity is behind the plane can fly out, and the area of the rudder should also be large enough, after all, when flying sideways, the side of the body becomes a lift surface, and the rudder becomes an elevator.

The MiG-29 is flat, and the side area is not very large, but it has two super large rudders, so it is quite stable to do this exciting action, and now, the MiG-29 is so sideways, with the cockpit canopy facing the audience, and the side flight through the field!

Everyone was stunned, if it was a pilot specially prepared for aerobatic performances, it was acceptable, and if the average random pilot could reach this level, it would be too powerful, right?

In particular, when it flew halfway to the side, suddenly, the fuselage began to roll, and it made a turn around the axis, just the cockpit facing the audience, and now the belly facing the audience, and the details of the belly can now be seen clearly, the air intake, the bulging engine compartment, the depression between the two engines, and so on.

"Not good!" At this moment, Qin Feng suddenly discovered something and shouted, "Run!" ”

Come on?

Before the others could react, Qin Feng was already nimble, pulling General Lin with one hand and Tu Lao with the other, and began to run backwards.

Qin Feng had no time, so he could only pull the people around him, and then everyone understood that when the fighter was flying sideways, the pilot's altitude estimation of the plane was wrong, and when the plane turned, there was a loss of lift, so the plane lost altitude, and when it turned over, the wings below were no longer enough safe distance!

The end of the wing, first of all, came into contact with the ground, and at the moment of contact, the wing made a crisp sound, even exceeding the roar of the engine, and disconnected from the middle!

It was a flight accident!
