"good."

Zhou Hai let go of the joystick, wearing Type 07 pilot glasses, stared at the blue halo in front of him, and was looking forward to the upcoming supersonic flight.

After taking over the control, Yang Xiaolong checked the flight parameters through the airborne avionics. Everything was normal, the fuel remaining amount was 76%, clamped the joystick and turned on the engine afterburner device.

"Boom!" In a flash, the afterburners of the two engines on both sides were supplied with oil and ignited, and the engine whistled even louder, like thunder, spreading all over the sky.

A pointed orange-red high-temperature tail flame spewed out at the tail end, dazzling and eye-catching.

The ‘Minshan’ WS-17 aviation turbofan engine can output up to 4,750 kilograms of terrifying thrust under the afterburner state, which is a proud data for the small thrust turbofan engine.

With Falcon only 76% of its fuel capacity and no external weapons load, the two Minshan engines burst out with a total of 9,500 kilograms of thrust, which all acted on the body, making the thrust-weight ratio of the entire machine exceeding the threshold of 1.

Flows of high-quality aviation fuel flow through the oil pipeline, supplying two industrial flowers that entered the state of afterburner oil swallowing. The flight parameters of the monitor on the left are changing wildly, and the airspeed meter shows a geometrical situation.

accelerate!

Flying at an altitude of 12,000 meters and bathing in the sun, the L-15C Falcon shows the style of a king of higher education aircraft.

Speed ​​1000 km/h!

Speed ​​1100 km/h!

Speed ​​1200 km/h!

At this time, the entire L-15C Falcon is in the transsonic stage, with shock waves locally generated in the fuselage, air resistance increases sharply, lift will be greatly reduced, and the body seems to be stuck in a mud and it will be difficult to move, causing a certain degree of turmoil.

Although the fuselage adopts a wing body fusion design and has excellent flight performance, greatly reducing the influence of the mixed flow field formed by subsonic airflow and supersonic airflow on the surface of the fuselage, even so, the transsonic area is still the most dangerous and necessary area for supersonic flight.

This is a flight restricted area!

"Boom!" A few seconds later, a sound of explosion like thunder resounded through the sky and spread throughout the sky.

The L-15C Falcon, which is shrouded by strong pressure waves in half-load state, has a conical white shock wave cloud blooming on the roots of the two wings and the middle section of the fuselage. Its shape is standard and trembles people's hearts.

Sound boom clouds that emerge from the laws of physics!

Zhou Hai, who was in the cockpit, felt a pressure on his body. At the moment when the body broke through the sound barrier, the world fell into silence, leaving only Yang Xiaolong's slightly rapid breathing sound in his helmet and headphones.

Quiet!

True silence, as if the world is solidified, is a wonderful and unique feeling.

The scorching sun hanging in the distance in the sky released light and heat. The L-15C falcon, which has entered a supersonic flight state, only needs to keep flying at a speed of Mach 2 in the west, it can exceed the angular speed of the earth, just like Kuafu in the mythical world, chasing the sun.

"Zhou Hai, what do you think?" At this time, Yang Xiaolong's somewhat rapid voice sounded from the military encrypted communication channel.

When Zhou Hai heard Yang Xiaolong’s question, he responded gently, giving his inner feelings, and was not stingy with his evaluation: "Very good, the world of supersonic flying is very quiet, peaceful, and has a hint of passion, and the flight experience is excellent."

At this moment, the real airspeed is 1550 kilometers per hour!

Sitting in the supersonic flying war eagle cockpit, a sense of peace arises in my heart, which is fascinating.

Such a wonderful feeling, after the retirement of the Concorde supersonic passenger plane, ordinary people in the world can no longer experience it. Even the pilots of civil aviation passenger planes can only fly passenger planes as slow as snails and cannot touch the field of supersonic flight.

This is the experience of being an Air Force pilot, and the romance and sentiment of the profession of pilots.

Think about it, how romantic it would be if you had the opportunity to fly supersonics at a height of 10,000 meters, look down at the vast earth, and look up at the desireable universe?

Of course, there should be no chance to fly with girls, or the possibility is very small.

Yang Xiaolong's words were quick and he was a little amused and laughed: "I said if you have any feelings in your body, and I didn't ask you about your inner feelings and thoughts."

Hearing these words, Zhou Hai quickly replied: "There is no body."

"That's good. Let me explain to you that when breaking through the sound barrier, you must be fast and stable. You are very clear about the situation in the transsonic area. The airflow is very complicated. Due to the increase in resistance and the reduction in lift, the body will tremble."

Yang Xiaolong breathed a sigh of relief and said, "Long-term transsonic flight will seriously damage the structure of the fuselage and affect the life of the aircraft. You know all this, so I won't say much. I slow down and give you control later. You can fly supersonic once."

"Yes!" Zhou Hai nodded and replied, his powerful voice exuding expectations.

Yang Xiaolong, who was in the back seat, performed a series of operations, turned off the engine after-force device, and steadily controlled the L-15C Falcon to gradually slow down, breaking away from the supersonic flight state, and recovering from the temporary tremor and bumping.

Yang Xiaolong, who was greatly exhausted, gasped slightly, put the pole back and handed over the control of the body to Zhou Hai.

"Teacher Yang, are you okay?" Zhou Hai held the sensitive joystick again in his right hand. Hearing Yang Xiaolong's breathing, he couldn't help but worry.

Yang Xiaolong responded cheerfully: "It's okay, it's just that the physical energy is consumed too much. You can return after flying the supersonics. Today you are doing very well. If you accumulate 30 flight hours, you can fly solo. Come on."

"I will."

Zhou Hai looked at the blue halo in front of him that seemed to be connecting the heaven and earth. He held the joystick in his right hand, opened the engine with his left hand and pushed the throttle valve upwards.

The two engines re-entered the afterburner state, and the L-15C Falcon, which was flying smoothly underneath, seemed to resonate with his heart, reacted and accelerated to fly forward.

Calm and powerful.

The war eagle shuttled through the thin air at altitude, and its flight speed became faster and faster. The air resistance increased in geometric form. After ten seconds, the silver-gray body shrouded by strong pressure waves, after a violent and brief tremor, it once again appeared a conical white shock cloud.

"boom!"

The thunder sounded around, and the world fell into silence again, with a peaceful aura filled with the L-15C Falcon steadily breaking through the sound barrier and entering a supersonic flight state.

Speed ​​1300 km/h, Mach 1.06.

"It still feels so wonderful." Zhou Hai held the metal joystick tightly, watched the surrounding world through the cockpit glass, his mind throbbing, and his eyes were filled with intoxication.

At this time, Yang Xiaolong's voice sounded: "Okay, Zhou Hai, slow down and return. Today's training ends here, and continue to take the flight tomorrow."

At the rear position, Yang Xiaolong breathed onboard oxygen, picked up the tactical tablet terminal with his hand, clicked on the screen, and gave an evaluation to Zhou Hai's student score record form.
Chapter completed!
