"OK."
After hearing Yang Xiaolong's instructions, Zhou Hai nodded, turned off the engine's afterburner device, adjusted the fuel supply, and when the L-15C Falcon left supersonic speed and returned to the subsonic flight area, he immediately pulled the stick back and turned left with full rudder and returned.
The fuselage pulled out a graceful arc in a slow manner, and the two aviation engines returned to normal working conditions. A steady stream of high-temperature airflow was ejected from the rear end, mixing with the air in the cold and extreme environment, and the water vapor condensed into two ribbon-like ribbons. White trailing clouds.
These two contrail clouds cannot be dispersed for a long time, like the pen in the hand of a painter, sketching out a wonderful scene like a picture scroll at an altitude of 12,000 meters.
Turn around and fly smoothly along the return route.
"Zhou Hai, you should know about the academy's notice about the Sky Eagle military exercise yesterday, right?" Yang Xiaolong, who was staying at the rear of the cockpit, said softly.
Zhou Hai heard this and responded: "I know."
"According to this progress, you will basically be able to participate in the exercise in August. Perform well in the Tianying military exercise. I only have one request from you, which is to penetrate 300 kilometers to the Quzhou base." Yang Xiaolong exhaled and said, revealing his thoughts: "If you enter, there will be a surprise waiting for you."
Looking at the blue sky in front of him, Zhou Hai was silent, his mind was lost in thought, and he was a little confused: "Teacher Yang, is there no way to complete the military exercise mission? Assuming that we penetrate the defense at ultra-low altitude, we may be able to avoid the Air Police 2000 and J-P -10 fleet."
300 kilometers!
Yang Xiaolong's request was only to break into the location 300 kilometers away from the Quzhou base, which puzzled Zhou Hai.
We don’t seek to complete the mission or win the military exercise. Why is this?
And the surprise, what is it?
"You will understand later. It's too early to talk about this now. Train well." Yang Xiaolong responded with a smile on his face without revealing the details about the Skyhawk military exercise.
After hearing these words, Zhou Hai shook his head slightly, stopped talking, and flew with peace of mind.
He had to admit that both his master and flight instructor Yang Xiaolong, including himself, were used to saying this when they didn't want to answer questions - you will understand later.
The two WS-17 turbofan engines maintained low thrust. The L-15C Falcon, flying at an altitude of 12,000 meters, encountered a Boeing commercial airliner about 20 kilometers away on its way back.
Ten minutes later, the L-15C Falcon returned to the airspace outside Shicheng along the route, gradually lowered its flight altitude, and flew towards the college airport, preparing to approach and land.
"Call the tower, No. 109 is preparing to approach and request landing." Zhou Hai switched to the military encrypted communication channel and sent a landing request to the college airport tower.
"The tower has received it. The ground wind is due south and southwest, wind speed is level 3, gust level 4, and there is no crosswind. Landing is allowed. Please land on runway one." The clear and ethereal voice of the female tower controller sounded, and she quickly gave a series of ground instructions parameter.
"Received on the 109th, ready to land."
Zhou Hai held the flexible and light metal joystick, pressed forward slightly, stepped on the rudder with both feet, and controlled the aircraft to change its attitude and enter the outer perimeter of the airport, aligning the nose of the aircraft with runway one.
On the ground, one after another the ground crew members looked up after hearing the sound, all their eyes focused on the L-15C Falcon that was about to land. This aircraft has an extraordinary status in the entire academy and is the king of higher education aircraft.
The speed is reduced, the flight altitude is reduced, and the attitude is correct and stable.
Accompanied by the scream of the engine that resounded around the runway, the silver-gray L-15C Falcon showed an elegant posture. The three-point landing gear on the lower side of the belly slowly protruded. The Bayi logo in the middle of the single vertical tail was visible, and the nose of the aircraft was slightly tilted. Lean up a few degrees.
The landing speed of the l-15c Falcon is very friendly to higher education students, only 200 kilometers per hour.
If the JJ-7 has poor flight performance and an outdated design, its landing speed can be as high as 330 kilometers per hour.
This number is a nightmare for every higher-education aircraft pilot. There is a gap of 130 kilometers per hour between the L15C Falcon higher-education aircraft.
Don’t underestimate the gap of only 130 kilometers. In the aviation field full of rigorous and demanding atmosphere, the critical reduction of landing speed and stall speed is 10 kilometers per hour. One step forward requires a strong aviation industry and a series of cutting-edge aviation technologies. support.
Even the Shanying Higher Education, which was born out of the J-7, still has a landing speed of up to 260 kilometers per hour, which is far inferior to the L-15c Falcon.
"squeak!"
The high-performance tires of the landing gear came into contact with the concrete runway surface, causing friction, rolling at high speed, deforming slightly, and making a thin and sharp sound, hidden in the sound of the engine.
A slight but unavoidable bump spreads throughout the fuselage. The integrated wing-body design and fly-by-wire flaperon system greatly reduce the impact of turbulent wind speed and dense airflow during landing.
"boom!"
Immediately afterwards, a dull sound came out, the single vertical tail end closing device opened, and a white umbrella flower bloomed immediately, fully opened, providing a drag area, and cooperating with the flaperons and spoilers to slow down.
The L-15C Falcon, with a speed of up to 200 kilometers per hour, quickly reduces its taxiing speed.
"It's so handsome. We only have four new Falcons in our college. If only I could get into the crash course, I might be able to get one to try." A higher education student sitting in the Shanying B-type cockpit, his eyes Watching the sci-fi-like L-15C Falcon gliding smoothly on Runway 1, I felt a strong sense of envy.
The flight instructor's calm words came from behind: "Boy, wake up, stop daydreaming, fly your own plane and get ready for takeoff."
"..." After hearing the teacher's words, the body of the College of Higher Education stiffened, and he sighed in his heart, with a look of resentment in his eyes.
After landing safely, Zhou Hai held the joystick and controlled the war eagle under him to the taxiway.
The L-15C Falcon, which gathered the attention of many people, left the runway No. 1 and entered the taxiway. Two Shanying A-type high-education aircraft waiting at the starting point of the standby runway entered the runway one after another to accelerate takeoff and conduct flight training.
The entire airport once again fell into a state of continuous high-intensity training.
flight!
This is the most important task in the higher education stage and the life theme of every student.
"Buzz!"
Soon, the L-15C Falcon, which was traveling on the ground at a speed of tens of kilometers per hour, entered the apron area. Under the arrangement of a ground crew member with a flag signal, it turned and entered the No. 20 shed-style apron. stopped.
Zhou Hai moved his hands flexibly, shut down the two WS-17 turbofan engines in sequence, returned the fuel supply switch, and checked the flight parameters displayed by the onboard avionics system. Everything was normal and there was no problem. Then he shut down the avionics and cut off the power supply. .
The roar of the engine gradually weakened, the high-temperature airflow disappeared, and the white umbrella hanging from the tail of the plane fell powerlessly.
The ground staff who were staying around the shed-type apron quickly gathered around.
