As for small and medium-sized countries?

No kidding, just go and play the old and backward second-generation supersonic fighters.

To put it more plainly, go play in the mud.

"Boom!"

Dozens of seconds later, the sound of two S-17 aviation turbofan engines sounded, and the entire L-15C Falcon, which embodies cutting-edge technology and wisdom, was guided by ground crews to slowly slide out of the tarmac, following the silver-white J-10A figure, sweeping towards the taxiway.

Take off, lift off.

The two warhawks raised their heads slightly, took off empty, and swept towards the hot and blue sky.

"No. 1, climb to a height of 10,000 meters, I can't give you a specific demonstration of this maneuver, you need to operate it yourself, the canard wing aerodynamic layout of the fighter due to the aerodynamic characteristics, temporarily can not do the Herbst maneuver, the main reason why the L-15C Falcon can do the maneuver, relying on the fuselage middle section of the pointed arch large edge strip and the optimized and upgraded flaperon system, in the process of maneuvering, can provide a yaw moment that is conducive to interfering with vortex and high angle of attack."

Lin Jian wore a standard standard helmet, steadily pulled the lever to face the sky, and transmitted to Zhou Hai the detailed operation content of the Herbst maneuver through the encrypted communication channel:

"First of all, the speed is Mach 0.55, the tie rod climbs at the maximum angle of attack, at the edge of the edge of the upcoming stall, around the vertical axis to the right full rudder yaw and roll, maintain a high thrust state, control the fuselage to pin along the predetermined flight trajectory, the apex position pine oil deceleration, the formation of inertia, until the nose and trajectory direction are opposite to the initial trajectory direction, forming a 180 ° angle, the engine is full of fuel and afterburner, detached to complete this action, understand?"

"Understood."

Zhou Hai kept the lever climbing, and when he heard the details and main operation steps explained by Lin Jian, his brain, which was running at high speed like a computer, immediately used these key information to build and deduce, and began to simulate.

"Repeat." When Lin Jian heard this, he asked.

Without the slightest hesitation, Zhou Hai immediately recounted the specific operation steps given by Lin Jian: "The first step is to pull the rod to the end and climb the ...... at the maximum angle of attack."

The voice is calm, which can be called precious content information, and not a word is missed.

"Yes, remember a little, stay calm, don't be afraid."

Lin Jian praised and instructed: "When implementing the Herbst maneuver, due to the very complex aerodynamic characteristics and airflow of the aircraft, it is on the verge of stalling, and the operation process must be fast, there must be no hesitation and hesitation, and the timing must be just right. It's a test, and I hope you succeed the first time and set an example for everyone. ”

Pass the difficult test and set an example.

This is Lin Jian's expectation of Zhou Hai, and why he did not follow Zhou Hai to sit in the L-15C Falcon and implement it personally.

Completing alone and being led by an instructor are completely two different concepts, and Lin Jian hopes that Zhou Hai can reach the level of the former and climb to the tactical peak that a few people have set foot on.

Even if the L-15C has been specially optimized and upgraded to meet the requirements of maneuvering, the pilot still needs to master the difficult operation technology.

And this is precisely the gap between the old fly and the new fly.

"Yes."

Zhou Hai stared at the blue sky that was getting closer and closer overhead, and responded softly, his high-speed mind had simulated the process of implementing dozens of Herbst maneuvers, making full use of his advantages.

The ability to remember, such as a cutting-edge supercomputer-like brain, is a non-human strength, allowing him to conceive relevant images and content and develop mental simulations.

Mock!

Crazy simulation!

At the same speed, the turning radius is shortened by five times, the energy loss rate is insignificant, and it can be made continuously, which is far from the 'one-shot deal' of instantaneous maneuvering.

Fifty times,

A hundred times,

Two hundred times,

In the short process of climbing from a low altitude to an altitude of 10,000 meters, Zhou Hai frantically consumed his energy, synthesized the important knowledge of aerodynamics, fluid mechanics and flight mechanics he had learned, and simulated the entire maneuvering process without interruption as usual.

This is Zhou Hai's unique way of learning.

As long as you master this maneuver thoroughly, the next time it is your turn to work the night shift, it will not be a problem at all to defeat the Japanese students in 20 seconds.

This is a peerless secret book in the public version of the air combat field, but only a few people can comprehend it.

At an altitude of 10,000 meters, the sun is even hotter, and even with the advanced aircraft environmental control system, which automatically maintains the pressure, temperature and humidity in the cabin, it is still impossible to avoid the boiling heat falling overhead.

Direct sunlight, it's an ordeal.

"Number 1, prepare for the maneuver."

Lin Jian, who was sweating on his forehead, changed the pressure rod, and the slightly bulky J-10A flew forward horizontally, as did the L-15C Falcon that followed on the right hand.

Zhou Hai ended the thinking simulation process of nearly three hundred times, and his voice was calm and powerful, revealing a strong sense of confidence: "Received on the 1st." ”

As the words fell, his deep eyes stared at the blue halo of the sky ahead, pushed the throttle valve up, and grasped the joystick tightly with his right hand, controlling the L-15C Falcon under him to accelerate.

"Buzz!" The engine is getting louder and louder, and the left and right wings are swept through the thin air, and the speed of the ship increases geometrically.

In an instant, when the speed approached Mach 0.55, the silver-gray nose suddenly lifted into the maximum elevation angle, and the two S-17 turbofan engines burst out with abundant power.

The entire L-15C Falcon climbs towards the blue sky!

At the end, there is a white trail cloud like silk, beautiful and soft.

At this time, with the increase of the angle of attack of the fuselage, the left and right wings are on the verge of the stall critical line, and in the state of high angle of attack, the left and right aerodynamic rudder surfaces begin to change sharply, showing a reverse yaw effect—the yaw efficiency of the flaperon differential is enhanced, the roll efficiency is attenuated, the yaw effect of the tail rudder continues to weaken, and the roll effect is enhanced.

What's going on?

In short, at a high angle of attack, all the operation methods are reversed!

The yaw changes from rudder to aileron, and the roll changes from aileron to rudder. - This extremely abnormal and extreme mode of operation, which is diametrically opposed to the original aerodynamic effect of the aircraft, is the unique characteristic of the high angle of attack and high sideslip angle state.

The operation mode is reversed, and the pilots who have formed the original operation habits, subconsciously make a little mistake, which may lead to the failure of the maneuver and even enter the forbidden area of stall tailspin.

And this is precisely where the difficulty of implementing the Herbst maneuver by purely pneumatic means lies, and it is extremely challenging for the pilot's operating skills.

In the blue sky, in the cockpit, the surrounding scenery rotates.

Zhou Hai's face was calm, calmly and calmly controlled the L-15C Falcon on the verge of stalling, with a precise and bold cut, around the vertical axis spinning, after a height of more than 200 meters, the body of the machine rotated to the angle of the fixed point, the two S-17 engines instantly slowed down, and the huge inertia had an effect.
