Bai Tangfei smiled.
Wang Zhuyu on the side looked calm and cast his eyes on the No. 109 L-15C Falcon that was driving smoothly on the taxiway.
Now, the special training trainees on the ground were studying the code names and the comprehensive single-machine assessment while paying attention to Zhou Hai, who was the first to be assessed.
In order to hone the students' tactical awareness to the greatest extent, the single-aircraft comprehensive assessment is not accompanied by a formal pilot, and everything needs to be completed alone.
The order of assessment is arranged by results, with assessment taking place first, which is also a kind of affirmation and a sign of strength.
In other words, it is not possible to arrange the initial assessment for you just by thinking about it.
The L-15C Falcon, carrying a PL-8B short-range combat missile, moved forward slowly. The main and auxiliary landing gear aviation tires carrying the semi-empty body rolled on the cold and dry concrete surface of the taxiway, deforming slightly. , streams of high-temperature air flow like torrents swept out of the tail nozzle, releasing billowing heat waves.
"Call the tower, Student No. 1 requests to take off."
Holding the metal joystick, Zhou Hai stared at the getting closer and closer to the main runway entrance, stared at the straight and slender main runway on the right, turned on the radio equipment, and sent a takeoff request to the Quzhou base tower.
Everything seemed familiar.
"Student No. 1, the ground wind is southeasterly, wind speed is level 3, gust level 4, no crosswind, the target airspace has cleared, permission to take off." The controller of the Quzhou base tower immediately responded in accordance with the procedure, granted takeoff permission, and reported a series of ground wind direction data : "Wish you a safe journey and a smooth flight."
"Students received it on the 1st and are ready to take off."
After obtaining the takeoff permission from the tower, Zhou Hai, who was staying in the cockpit, could feel the eyes from all over the base and the attention of Commander Lin Jian. His eyes were focused, his heart was serious, and he took a deep breath to operate.
With your right hand, press the bar forward.
Press the rudder to the right to change direction.
Today's single-machine comprehensive assessment, the core content is to launch live ammunition to attack the target drone. This is Zhou Hai's first experience in his service career, so he needs to be cautious.
Under the gaze of many personnel, the silver-gray L-15C Falcon slowly turned and entered the entrance, aiming at the straight and slender main runway. The sound of the turbofan engine gradually became louder and louder, outputting higher and higher thrust, pushing the aircraft body. Sliding at high speed.
Speeding for more than 200 meters, as he reached the critical speed for takeoff, the left and right wings provided high lift. Zhou Hai instinctively pulled the lever to raise his head, chose a normal and precise angle of attack, and raised his head to face the sky.
Spread your wings and soar.
"Call the tower. Student No. 1 requested to perform the air combat maneuver assessment." Zhou Hai held the joystick and kept flying in a circle, observing the body data and flight parameters displayed on the left and right screens of the aircraft, and then sent a request to the base tower.
The altitude is three thousand meters and the speed is four hundred.
"Student No. 1, permission to execute."
The tower controller sitting on the chair, holding a high-power optical telescope in his hand, stared at the L-15C Falcon flying smoothly in the sky and gave instructions.
Next to him, stood an invigilator officer affiliated with the base's special training command, holding a tactical tablet in his right hand with a serious face, ready to record Zhou Hai's comprehensive single-machine assessment results at any time.
A series of equipment such as the base's optical observation equipment and military high-definition cameras simultaneously locked onto the L-15C Falcon in the sky.
After receiving the controller's order, Zhou Hai pushed up the throttle with his left hand, pressed the lever with his right hand and stepped on the rudder, returning to the hovering state. Then he accelerated to accumulate energy, and suddenly pulled the lever to raise his head to the maximum elevation angle.
The attitude of the L-15C Falcon suddenly changed. With the aerodynamic effect provided by the large pointed arch side strips and the flaperon aerodynamic rudder surface, the nose of the aircraft quickly tilted back, and the tail of the aircraft was pressed forward under the action of inertia, as if it was raised high. Entering an attack stance like a cobra.
This is the most classic Cobra maneuver in the history of aviation. The official name is the Pugachev Cobra maneuver. It was piloted by the Soviet test pilot Viktor Pugachev at the Paris Air Show, flying the Su-27 'Flanker' heavy-lift The air superiority fighter executed the entire maneuver, shocking the audience and sensationalizing the entire world.
In that era, the Su-27 Flanker family became a unique benchmark among the third-generation aircraft precisely because of the Cobra maneuver, climbing to the top and becoming world-renowned.
The L-15C Falcon, which has entered a new era, embodies a variety of cutting-edge aviation technologies, adopts three-axis four-degree fly-by-wire control and advanced airborne avionics, and implements the Cobra maneuver that was once hailed as ultra-difficult. No difficulty.
"Buzz!"
Accompanied by the roar of the engine, the L-15C Falcon, which was flying like a cobra and in an extreme state of high angle of attack, saw its speed drop sharply from 430 kilometers per hour. Then, with the two WS-17 'Minshan' The engine output a high amount of thrust, and the nose of the aircraft was quickly pushed forward and no longer tilted back. It successfully recovered from the Cobra maneuver and maintained level flight.
After completing this classic maneuver, the L-15C Falcon returned to level flight without any pause or sluggishness. It accelerated to 500 kilometers per hour again, the nose of the aircraft was raised again, and the fuselage changed its flight attitude. At the angle of attack state, Zhou Hai suddenly pulled the throttle valve to slow down the thrust and keep the two engines at idle speed.
The L-15C Falcon, which was maintaining a climbing attitude, lost thrust and gradually decelerated. The lift provided by the left and right wings dropped sharply like a cliff. After rising to an altitude of more than 200 meters, the energy contained in itself was exhausted and the climb was terminated.
On the left screen in the cabin, the speed is displayed as 0 and the altitude is 3280 meters.
At this time, the entire War Eagle's flight attitude is tilted forward, at a high angle of attack, with the nose up and the tail down, forming one of the advanced air combat maneuvers in the aviation field - the tail rush maneuver.
The rear end of the engine is facing the vast land below.
Brilliant, colorful.
Time seems to be frozen at this moment.
Immediately afterwards, the L-15C Falcon, which maintained a forward leaning posture with a high angle of attack, entered a state of free fall under the influence of gravity, and hit the ground vertically like a stone.
"boom!"
After descending about a hundred meters, the two WS-17 turbofan engines at idle roared, bursting out with a maximum thrust of up to 9,500 kilograms. The cone-shaped high-temperature orange-red color was dazzling. The carrying body climbed upwards, and then recovered. Tail thrust maneuver.
The whole process seems long, but is actually short, less than ten seconds.
In fact, if the Air Force is willing to spend money in its trouser pockets to equip the L-15C Falcon with a vector turbofan engine, the execution time of the tail thrust maneuver will be shortened by more than twice, and it will have super maneuverability comparable to fourth-generation fighter jets.
Of course, spending a huge amount of money to replace the L-15C Falcon with a vector turbofan engine is obviously a bad deal.
Higher education aircraft should be treated as higher education aircraft. Don’t think about competing with third-generation aircraft all day long to steal jobs from fourth-generation aircraft.
After executing two advanced air combat maneuvers in succession, Zhou Hai did not hesitate and moved towards the Herbst maneuver, which was the most difficult and technically demanding in the field of stall maneuvers.
