"good."
Zhou Hai let go of the control stick, wore 07-style pilot glasses, and stared at the blue halo directly ahead, looking forward to the upcoming supersonic flight.
Taking over the control, Yang Xiaolong checked the flight parameters through the onboard avionics. Everything was normal. The remaining fuel level was 76%. He held the control stick tightly and turned on the engine afterburner device.
"Boom!" In an instant, the afterburners of the left and right engines supplied fuel and ignited, and the screams of the engines became louder, like thunder, spreading across the sky.
The tail end sprays out a sharp orange-red high-temperature tail flame, which is dazzling and eye-catching.
The 'Minshan' ws-17 aviation turbofan engine can output a terrifying thrust of up to 4,750 kilograms under afterburner, which is a proud figure for a small-thrust turbofan engine.
With only 76% of the Falcon's fuel remaining and no external weapons loaded, the two Minshan engines burst out a total of 9,500 kilograms of thrust, all of which acted on the body, causing the thrust-to-weight ratio of the entire aircraft to exceed the threshold of 1.
Streams of high-quality aviation fuel flowed through the oil pipeline, supplying the two Industrial Flowers that entered the afterburner state and swallowed fuel. The flight parameters on the left display changed crazily, and the airspeed indicator showed a geometric increase.
accelerate!
Flying at an altitude of 12,000 meters, bathed in the sun, the L-15C Falcon showed its elegance as the king of higher education aircraft.
1,000 kilometers per hour!
1100 kilometers per hour!
1,200 kilometers per hour!
At this time, the entire L-15C Falcon is already in the transonic speed stage. Shock waves are generated in parts of the fuselage, air resistance increases sharply, lift will be greatly reduced, and the fuselage seems to be stuck in a quagmire, unable to move, and a certain degree of turbulence will occur. .
Although the aircraft body adopts a wing-body fusion design, which has excellent flight performance and greatly reduces the influence of the mixed flow field formed by subsonic airflow and supersonic airflow on the surface of the aircraft body, even so, the transonic area is still the most dangerous area for supersonic flight. .
This is a restricted area for flying!
"Boom!" A few seconds later, a thunderous explosion resounded through the clouds and spread across the sky.
The L-15C Falcon, which was in a half-load state and was shrouded by strong pressure waves, had a cone-shaped white shock wave cloud blooming from the wing roots and the middle section of the fuselage. The shape was standard and shocking.
Sonic boom clouds derived from the laws of physics!
Zhou Hai, who was staying in the cockpit, felt only a pressure acting on his body. The moment the machine broke through the sound barrier, the world fell into silence, and the only sound left was Yang Xiaolong's slightly rapid breathing in the helmet earphones.
Quiet!
Real silence, as if the world has frozen, is a wonderful and unique feeling.
The scorching sun hanging in the distance in the sky releases light and heat. The L-15C Falcon, which has entered supersonic flight, can theoretically exceed the earth's rotation angular speed just by flying due west at Mach 2, just like the boast in the mythical world. Father, chase the sun.
"Zhou Hai, how do you feel?" At this time, Yang Xiaolong's urgent voice sounded in the military encrypted communication channel.
Hearing Yang Xiaolong's question, Zhou Hai responded gently, giving his inner feelings and unstinting evaluation: "Very good, the world of supersonic flight is quiet, peaceful, and a little passionate, and the flying experience is excellent." "
At this moment, the true airspeed is 1,550 kilometers per hour!
Sitting in the cockpit of a war eagle flying at supersonic speed, you will feel a sense of peace in your heart, which is intoxicating.
Such a wonderful feeling, after the retirement of the Concorde supersonic passenger plane, ordinary people around the world can no longer experience it. Even the pilots of civil aviation airliners can only fly passenger planes as slow as snails and cannot touch the thrill of supersonic flight. field.
This is an experience unique to air force pilots, and unique to the romance and feelings of the pilot profession.
Think about it, if you have the opportunity to carry a girl, fly at supersonic speed at an altitude of 10,000 meters, look down at the vast land, and look up at the longing universe, how romantic would it be?
Of course, there should be no chance of flying with a girl, or the possibility is very small.
Yang Xiaolong spoke hurriedly, somewhat dumbfounded: "I asked you whether you felt anything in your body, but I didn't ask about your inner feelings and thoughts."
Upon hearing these words, Zhou Hai quickly replied: "Not in body."
"Okay, let me explain to you. When breaking the sound barrier, you must be fast and steady. You know very well the situation in the transonic region. The airflow is very complicated. Due to the increase in resistance and the decrease in lift, the body will tremble."
Yang Xiaolong breathed a sigh of relief in his heart and said: "Long-term transonic flight will seriously damage the structure of the aircraft and affect the life of the aircraft. You all know these, so I won't say more. I will slow down and give you control later. You can fly once Supersonic."
"Yes!" Zhou Hai nodded and replied, his strong voice full of expectation.
Yang Xiaolong, who was staying in the back seat, performed a series of operations, turned off the engine afterburner device, and steadily controlled the L-15C Falcon to gradually decelerate and exit supersonic flight. After a brief tremor and bumps, it returned to stability.
Yang Xiaolong, whose physical strength was greatly exhausted, panted slightly, released the lever, and handed over control of the body to Zhou Hai again.
"Teacher Yang, are you okay?" Zhou Hai once again grasped the sensitive joystick with his right hand and asked with concern when he heard Yang Xiaolong's breathing.
Yang Xiaolong responded cheerfully: "It's okay, it's just that the physical exertion is too much. You can return after flying at supersonic speed. Your performance today is very good. If you accumulate 30 more flight hours, you can fly solo. Work hard. "
"I will."
Zhou Hai stared directly ahead at the blue halo that seemed to connect heaven and earth. He held the joystick in his right hand, turned on the engine afterburner with his left hand, and pushed up the throttle valve.
The two engines re-entered the afterburner state, and the L-15C Falcon flying smoothly below seemed to resonate with its heart, reacted, and accelerated to fly forward.
Calm and powerful.
The war eagle shuttled through the thin air at high altitudes, flying faster and faster, and the air resistance increased in a geometric form. Ten seconds later, along with the silver-gray body enveloped by strong pressure waves, after a violent and short tremor, a flower appeared again. Cone-shaped white shock cloud.
"boom!"
Thunder resounded all around, and the world fell into silence again, filled with a sense of peace. The L-15C Falcon steadily broke through the sound barrier and entered supersonic flight.
Speed 1300 kilometers per hour, Mach 06.
"It still feels so wonderful." Zhou Hai held the metal joystick tightly and looked at the surrounding world through the cockpit glass, his heart palpitating and his eyes filled with intoxication.
At this time, Yang Xiaolong's voice rang out: "Okay, Zhou Hai, slow down and return. Today's training ends here. We will continue flying tomorrow."
In the rear position, Yang Xiaolong breathed airborne oxygen, picked up the tactical tablet terminal with his hand, clicked on the screen, and commented on Zhou Hai's student performance record sheet.
The first actual flight results are excellent. ——
