The tires grind over the hard, high-quality concrete floor and slide off the shed-style tarmac.
The tail ends of the two WS-17 turbofan engines spurted out a torrent of high-temperature airflow with turbulent waves. After the entire new Falcon slid out of the apron, it turned right, slid smoothly along the road in the apron area, and entered the spacious taxiway. among.
The eyes of the surrounding higher education students and ground staff were all focused on the smoothly gliding L-15C Falcon, paying attention to this cutting-edge advanced trainer aircraft that embodies various domestic advanced aviation technologies.
If the L-15a Falcon has become one of the world's most advanced aircraft, 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 and kicking the T -38 and T-50 Golden Eagle have become the kings among higher education aircraft.
The real king!
This is the well-deserved pride of AVIC Hongfei Company. It embodies the wisdom and hard work of generations of aviation people and is a shining pearl.
In the next thirty years, in the world's aviation field, only the US military's TX high-education aircraft program, which is under development, can compete with the L-15 Falcon series.
In the airport flight area, the unique engine scream of the L-15C Falcon has almost become the main theme of the moment. The two Shanying B-type higher education aircraft that were about to slide out of the apron silently paused the slide out and watched the number 103 quietly. An L-15C Falcon slides into an airport taxiway.
As the latest improved version of the Mountain Eagle, it is completely different from the L-15C Falcon, which has an advanced and sci-fi atmosphere.
"Call the tower, No. 103 is requesting takeoff." Zhou Hai, wearing a new type of pilot helmet, turned on the portable airborne radio switch on the right side of the helmet, accessed the military encrypted communication channel, and sent a takeoff request to the airport tower.
A clear female voice sounded like a trickle in the military encrypted communication channel, giving a series of flight parameters: "No. 103, surface wind due north, wind speed level 3, gust level 4, no crosswind, field pressure 1015, sunny weather, Permitted to enter the main runway and allowed to take off, please perform flight training missions along the scheduled route."
"Received on the 103rd, ready to take off."
After receiving permission to take off, Zhou Hai took a deep breath and stared through the drop-shaped protective glass at the spacious and straight main runway in front of him.
The L-15C Falcon, staying on the taxiway, turned and slowly slid into the main runway, with the drop-shaped glass cockpit reflecting dazzling light.
The screams of the two turbofan engines are getting louder and louder, like the neighing of an eagle soaring in the sky. More and more high-quality aviation fuel enters the combustion chamber through the oil pipeline, generating abundant and high power. The tail nozzle A sharp, high-temperature orange-red tail flame that reaches thousands of degrees Celsius emerges.
Increased thrust!
Under the watchful eyes of many ground staff and student pilots at the airport, the L-15C Falcon turned and entered Runway 1, accelerating and taxiing 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 taxiing speed of the aircraft to the critical take-off line of 220 kilometers per hour.
Zhou Hai looked at the airspeed displayed on the aircraft's avionics system. Without hesitation, he moved his right hand gently and powerfully, pulling the lever directly behind, raising the nose of the aircraft, and changing the angle of attack of the fuselage.
Gentle and steady.
The angle is normal and the posture is stable.
The angle of attack is the biggest enemy faced by flight students in the advanced aircraft training stage. If the angle of attack is too high during takeoff, even if it does not exceed the limit of the maximum controllable angle of attack, it will cause a stall due to the influence of too low speed and low air flow, and the aircraft will then stall. out of control.
Although they have received professional aviation theory assessment, many students still make mistakes when faced with actual flight.
What angle of attack should be raised during takeoff and what flying attitude should be maintained? This is one of the tests of the first real flight.
The L-15C Falcon, which shines like a jewel, leaves the restraints of the concrete runway surface smoothly at high speed. The swept-back single wing splits the invisible and viscous air, generates airflow, and improves the aerodynamic efficiency of the flaperon system and rudder.
The nose of the plane was pointed at the blue sky, and it spread its wings and soared.
There was only a slight bump during the entire takeoff.
"Takeoff subject, excellent." Yang Xiaolong, who was sitting in the back cabin, clicked on the screen of the tactical tablet terminal to give an excellent evaluation and issued new instructions: "Zhou Hai, climb to an altitude of 4,000 meters, speed 450, prepare for the third Subject, overload limit assessment."
"clear."
Zhou Hai looked at the scheduled route given by the airport tower, pulled back the lever, and climbed upwards at a medium elevation angle. The altimeter data that was growing slowly suddenly increased like crazy.
Under the gaze of the crowd on the ground, the entire L-15C Falcon exuded pride, maintained a horizontal climbing posture, and quickly disappeared.
More than twenty seconds later, the L-15C Falcon, which had an excellent climb rate, reached an altitude of 4,000 meters, traveling at a speed of 450 kilometers per hour.
"Okay, if you feel unwell during the assessment, please notify me immediately and release the stick now." Yang Xiaolong put down the tactical tablet with a calm expression, put on the pilot's helmet and buckled the anti-G-force suit, and waited for Zhou Hai to take control of the aircraft after releasing the stick.
After handing over control of the body, Zhou Hai looked calm and didn't care about the upcoming overload limit test.
The first flight is not just to experience a jet aircraft, but to test whether the students are really suitable to fly in a high-education aircraft.
In addition to ground inspection and take-off assessment, the aircraft also needs to undergo the most important overload limit assessment - the non-equipment protective flight overload test.
The so-called 'non-equipment protection' means that the students do not take any protective measures, and the instructor tests the limits of the students' bodies to withstand overload through a series of high-g-load flights.
Han Li's performance was poor in this section. After a round of really high overload maneuvers, he almost fainted.
Fortunately, Han Li was still conscious after getting off the plane. He endured the feeling of vomiting and persisted, and passed the test for the first time on the plane.
Jet aircraft and propeller aircraft are completely different concepts. The vast majority of student pilots perform well in the initial training aircraft, and their level is extremely good. They are proficient in basic tactical maneuvers and fly like a fish in water.
But once it reached the stage of high-education aircraft, its performance was poor, and it was even completely unable to adapt. The wings eventually broke. The key reason was overload.
"boom!"
After Yang Xiaolong took over control of the aircraft, the entire War Eagle seemed to wake up. He opened his eyes, showed his kingly demeanor, and let out a louder roar.
Accelerating head-on, a strong pushing sensation was felt on the body. Immediately afterwards, the L-15C Falcon, with a silver-gray fuselage and a science fiction atmosphere, turned sharply to the right at a speed of nearly 500 kilometers per hour. The two wing strips cut through the sky like sharp blades, and the tail The orange-red high-temperature tail flame is dazzling.
As the high-speed moving war eagle changed its flight state and made maneuvers, an invisible force originating from the level of physics was exerted on the fuselage and the two people instantly.
