The tires run over the hard, high-quality concrete floor and slide off the tarmac.

The tail of the two S-17 turbofan engines spewed out a torrent of hot air, and the new Falcon slid off the tarmac, turned to the right, and glided smoothly along the apron area road into the wide taxiway.

The eyes of a famous senior instructor and ground staff all gathered on the smoothly taxiing L-15C Falcon, paying attention to this cutting-edge advanced training aircraft that condenses various advanced aviation technologies in China.

If the L-15A Falcon has been among the world's most advanced, then this latest improved L-15C equipped with two Minshan turbofan engines stands at the pinnacle of the field of higher education aircraft, punching the Yak-130, kicking the T-38 and T-50 'Golden Eagle', becoming the king of higher education aircraft.

A true king!

This is the well-deserved pride of AVIC Hongfei, which embodies the wisdom and hard work of several generations of aviation people, and is a shining pearl.

In the next nearly 30 years, in the world's aviation field, only the T-X high-education aircraft program that the US military is currently developing, can compete with the L-15 Falcon series.

In the flight area of the airport, the unique engine screeching sound of the L-15C Falcon has almost become the main theme of the current situation, and the two Mountain Eagle B high-education planes that are about to slide out of the tarmac silently slid out and quietly watched the L-15C Falcon numbered 103 slide into the airport taxiway.

As the latest improved version of the Mountain Eagle, it is not at the same level at all in the face of the L-15C Falcon, which contains an advanced and sci-fi atmosphere.

"Call the tower, 103 requests to take off." Zhou Hai wore a new type of pilot's helmet, turned on the portable airborne radio switch on the right side of the helmet, connected to the military encrypted communication channel, and sent a take-off application to the airport tower.

A crisp trickle-like female voice sounded in the military encrypted communication channel, giving a series of flight parameters: "No. 103, ground wind due north, wind speed level 3, gust level 4, no crosswind, field pressure 1015, fine weather, allowed to enter the main runway, allowed to take off, please perform flight training tasks along the predetermined route." ”

"Received on the 103rd, ready to take off."

With permission to take off, Zhou Hai took a deep breath and stared at the spacious and straight main runway directly ahead through the teardrop-shaped protective glass.

The L-15C Falcon, which stayed on the taxiway, turned and slowly slid into the main runway, and the teardrop-shaped glass cockpit reflected dazzling light.

The screeching sound of the two turbofan engines became higher and higher, like the neighing of eagles soaring in the sky, and more and more high-quality aviation fuel entered the combustion chamber through the oil pipeline, generating abundant high power, and a sharp high-temperature orange-red tail flame of up to 1,000 degrees Celsius came out from the tail nozzle.

Thrust increases!

Under the watchful eyes of many ground staff and flight students at the airport, the L-15C Falcon, which turned into Runway 1, accelerated and taxied like a sharp sword.

One hundred meters!

Two hundred meters!

Two hundred and twenty meters!

The two 'Minshan' engines, which maintain intermediate thrust, increase the gliding speed of the fuselage to the take-off threshold of 220 kilometers per hour.

Zhou Hai looked at the airspeed displayed by the on-board avionics system, and without hesitation, his right hand moved gently and powerfully, pulling the lever to the rear, raising the nose of the aircraft, and changing the angle of attack of the fuselage.

Gentle and steady.

The angle is normal and the attitude is stable.

If the angle of attack in the take-off stage is too high, even if it does not exceed the limit of the maximum controllable angle of attack, it will be affected by too low speed and low air flow, resulting in stalling, and the body will lose control.

Although they have received professional aviation theory assessments, many students still make mistakes when faced with actual flights.

How many degrees of attack angle should be raised during take-off and what kind of flight attitude should be maintained is one of the tests of the first actual flight.

The jewel-like L-15C Falcon smoothly exits the constraints of the concrete runway surface at high speed, splitting the invisible and viscous air with a single wing in the mid-sweep, creating airflow and improving the aerodynamic efficiency of the flaperon system and rudder.

The nose of the aircraft is aimed at the blue sky, and the wings are spread.

During the whole take-off, there was only a little insignificant bump.

"Take-off subjects, excellent." Yang Xiaolong, who was sitting in the rear cabin, clicked on the screen at the tactical tablet terminal, gave an excellent evaluation, and opened his mouth to give new instructions: "Zhou Hai, climb to a height of 4,000 meters, speed 450, prepare for the third subject, overload limit assessment." ”

"Understood."

Zhou Hai looked at the scheduled route given by the airport tower, pulled the rod back, maintained a medium elevation angle and climbed upward, and the altimeter data grew gently, and suddenly grew wildly.

Under the gaze of the crowd on the ground, the entire L-15C Falcon exuded pride, maintained a horizontal climbing posture, and the figure quickly disappeared.

After more than 20 seconds, the L-15C Falcon, which has an excellent climb rate, reached an altitude of 4,000 meters and sailed at a speed of 450 kilometers per hour.

"Okay, if there is any discomfort during the assessment, notify me immediately, and put the pole now." Yang Xiaolong put down the tactical tablet, his face was calm, he put on the pilot's helmet, buckled the anti-load suit, and obtained control of the airframe after Zhou Hai put the rod.

After handing over the control of the body, Zhou Hai's face was indifferent, and he didn't care about the upcoming overload limit assessment.

The first flight is not simply to experience a jet, but to test whether the trainees are really suitable to fly a high-level aircraft.

In addition to the ground inspection and take-off assessment, the most important overload limit test is the non-equipment protective flight overload test.

The so-called 'non-equipment protection' means that the trainee does not take any protective measures, and the instructor tests the limit of the student's body through a series of high-overload flights.

Han Li's performance was poor in this link, and he almost didn't get faint after a round of real high overload.

Fortunately, Han Li was quite conscious after getting off the plane, and he endured the feeling of vomiting, gritted his teeth and persevered, and passed the first time he got on the plane.

Jet aircraft and propeller aircraft are completely two different concepts, and the vast majority of flight students have performed well in the beginner training aircraft, with excellent skills, and are proficient in basic tactical movements.

However, when it comes to the stage of higher education aircraft, it performs poorly, or even cannot adapt at all, and finally folds its wings, and the key reason is overload.

"Boom!"

After Yang Xiaolong took over control of the body, the entire war eagle seemed to wake up, opened its eyes, showed its kingly demeanor, and let out an even louder roar.

Accelerating head-on, a strong sense of pushing back acted on the body, and then, the L-15C Falcon, which contained a sci-fi atmosphere in the silver gray of the fuselage, made a sharp turn to the right at a speed of nearly 500 kilometers per hour, and the edges of the wings seemed to be like sharp blades cutting through the sky, and the orange-red high-temperature tail flame at the tail end was dazzling.

With the high-speed movement, the warhawk changed its flight state and made a maneuver, an invisible force originating from the physical level, which was instantly exerted on the fuselage and the two people.
