As for small and medium-sized countries?
Stop joking, just go play with the old and backward second-generation supersonic fighter.
To put it more simply, go play in the mud.
"boom!"
Tens of seconds later, the sound of two WS-17 aviation turbofan engines sounded. The entire L-15C Falcon, which condensed cutting-edge technology and wisdom, slowly slid out of the apron under the guidance of the ground crew, following the silver-white J-10A. The figure swept towards the taxiway.
Take off, take off.
The two war eagles raised their heads slightly, took off without a load, and flew towards the hot and blue sky.
"No. 1, climb to an altitude of 10,000 meters. I can't give you a specific demonstration of this maneuver. You need to operate it yourself. Fighters with a canard aerodynamic layout cannot perform the Herbst maneuver due to their aerodynamic characteristics. The L-15C Falcon The main reason why this maneuver is possible is that the large pointed arch side strips in the middle section of the fuselage and the optimized and upgraded flaperon system can provide a yaw moment that is beneficial to disrupt vortices and high angles of attack during the maneuver."
Lin Jian wore a standard helmet, steadily pulled the lever toward the sky, and transmitted the detailed operation content of the Herbst maneuver to Zhou Hai through an encrypted communication channel:
"First, the speed is Mach 55, climb with the maximum angle of attack at the end of the pull rod, and at the edge of the stall, roll to the right with full rudder around the vertical axis, maintain a high thrust state, control the body to precess along the predetermined flight trajectory, and loosen the top position The oil decelerates and forms inertia until the nose and trajectory direction are opposite to the initial trajectory direction, forming an angle of 180°. The engine is full of fuel and turns on afterburner, and then disengages to complete this action. Do you understand?"
"clear."
Zhou Hai kept the lever climbing and after hearing the details and main operating steps explained by Lin Jian, his brain, which was running at a high speed like a computer, immediately constructed and deduced the simulation through these key information.
"Repeat it again." Lin Jian heard this and asked.
Without any hesitation, Zhou Hai immediately repeated the specific steps given by Lin Jian: "The first step is to pull the lever all the way and climb at the maximum angle of attack..."
His voice was calm and he could not miss every word of precious information.
"Yes, remember one thing, stay calm and don't be afraid."
Lin Jian praised and instructed: "When performing the Herbst maneuver, because the aerodynamic characteristics and airflow of the aircraft are very complex and it is on the verge of stalling, the operation must be fast, there must be no hesitation or hesitation, and the timing must be just right. This It’s a test, and I hope you succeed the first time and set an example for everyone.”
Pass difficult tests and set an example.
This was Lin Jian's expectation for Zhou Hai, and it was also the reason why he did not sit in the L-15C Falcon with Zhou Hai and implement it himself.
Completing it alone and being led by an instructor are completely different concepts. Lin Jian hopes that Zhou Hai can reach the level of the former and climb to the tactical peak that few people have set foot on.
Even if the L-15C has been specially optimized and upgraded, and its airframe performance meets the maneuvering requirements, the pilot still needs to master difficult operating techniques.
And this is precisely the gap between old and new flies.
"yes."
Zhou Hai stared at the blue sky getting closer and closer above his head and responded softly. His fast-moving mind had simulated the process of executing the Herbst maneuver dozens of times, making full use of his own advantages.
The ability of photographic memory, like a brain like a cutting-edge supercomputer, is a non-human advantage. It allows him to conceive relevant pictures and content and carry out mental simulations.
simulation!
Crazy simulation!
In actual combat, the practical value of the entire maneuver is beyond imagination. At the same speed, the turning radius is shortened five times, the energy loss rate is negligible, and it can be made continuously, far from being a 'one-shot deal' for instantaneous maneuvers.
fifty times,
a hundred times,
two hundred times,
In the short process of climbing from low altitude to an altitude of 10,000 meters, Zhou Hai frantically consumed energy, integrating the important knowledge he had learned such as aerodynamics, fluid mechanics and flight mechanics, and as usual, continuously simulated the entire maneuvering process.
This is Zhou Hai's unique way of learning.
As long as you master this maneuver thoroughly, next time it's your turn to work the night shift, it won't be a problem to defeat the Japanese students in twenty seconds.
This is the public version of the unique secret book in the field of air combat, but still only a few people can understand it.
At an altitude of 10,000 meters, the sun is even hotter. Even with an advanced aircraft environment control system that automatically maintains cabin pressure, temperature and humidity, it is still impossible to avoid the rolling heat falling overhead.
Direct sunlight is a torture.
"No. 1, prepare to carry out maneuver."
Lin Jian, with sweat on his forehead, pulled out the lever, and the slightly bulky J-10A flew forward and level, as did the L-15C Falcon following on the right.
Zhou Hai finished the thought simulation process for nearly 300 times, and his voice was calm and powerful, showing a strong sense of confidence: "Received on the 1st."
After finishing his words, he stared at the blue halo of the sky ahead with his deep eyes, pushed up the throttle, held the joystick tightly with his right hand, and controlled the L-15C Falcon under him to accelerate.
"Buzz!" The sound of the engine became louder and louder, sending out surging power. The left and right wings sliced through the thin air, and the speed increased geometrically.
In an instant, when the speed approached Mach 55, the silver-gray nose of the aircraft suddenly lifted into the maximum elevation angle, and the two ws-17 turbofan engines burst out with abundant power. Zhou Hai, who stayed in the cockpit, followed the specific operating steps and instructions given by Lin Jian. Three hundred times of thinking simulation experience, you can operate it skillfully and freely.
The entire L-15C Falcon climbed towards the blue sky!
At the end, there is a silky white trail cloud, beautiful and soft.
At this time, as the angle of attack of the fuselage increases, the left and right wings are close to the stall critical line. In the high angle of attack state, the left and right aerodynamic rudder surfaces begin to change sharply, showing a reverse yaw effect - the deflection of the flaperon differential. The navigation efficiency 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 happening here?
In short, under high angle of attack, the operation methods are completely reversed!
Yaw changes from rudder to aileron, and roll changes from aileron to rudder. ——This extremely abnormal and extreme operation method, which is completely opposite to the original aerodynamic effect of the aircraft, is the unique characteristic of the high angle of attack and high sideslip angle state.
Pilots who have reversed their operating methods and formed their original operating habits may make a slight mistake subconsciously, which may lead to failure of the maneuver or even entering the restricted area of stall and tail spin.
And this is where the difficulty lies in implementing the Herbst maneuver by purely aerodynamic means, which extremely tests the pilot's operating skills.
Under the blue sky, inside the cockpit, the surrounding scenery rotates and changes.
Zhou Hai looked calm and calmly controlled the L-15C Falcon, which was on the verge of stalling. He used a precise and bold angle cut to rotate around the vertical axis. After reaching an altitude of more than 200 meters, the aircraft precessed to a fixed angle. The two The ws-17 engine instantly loosened oil and decelerated, causing huge inertia to take effect.
