Under normal circumstances, most aircraft with poor flight performance, such as bombers, ordinary civil aviation aircraft, and transport aircraft, are strictly prohibited from entering a stall and tail spin state.
Once you enter, there is only one result - the destruction of the machine and the death of everyone.
Extremely dangerous!
However, every advanced fighter pilot student must deliberately put the aircraft into a stall and spin state and learn and train recovery techniques.
"Check the plane." Yang Xiaolong heard this and gave the order.
Without hesitation, Zhou Hai, who was full of expectations in his heart, turned to face the L-15C Falcon waiting quietly on the tarmac. It was only one day apart, and he was already itching to endure the charm of jet aircraft and supersonic speeds.
Zhou Haide had to admit that he had completely fallen in love with this high-education aircraft, which had an excellent flying experience.
Under the watchful eyes of all the ground staff and Yang Xiaolong, Zhou Hai circled the fuselage and carefully checked to confirm that it was correct. He returned to the front of the apron and raised his hand to report: "Comrade instructor, the aircraft has been inspected and everything is normal."
Yang Xiaolong nodded after hearing this, carefully rechecked the aircraft body, signed the aircraft acceptance document in the hand of the ground crew leader, and issued the boarding order.
The two climbed up the boarding ladder one after another and entered the cockpit. Zhou Hai performed a series of operations with his hands like flying. The drop-shaped glass cockpit cover slowly closed, and the ground handling team quickly became busy.
"boom!"
Tens of seconds later, the roar of the engine echoed all around.
The two turbofan engines on the left and right of the fuselage are operating stably and normally, and the tail nozzle sprays out high-temperature airflow, heating the evaporation shed and causing tiny raindrops to fly, creating a spectacular white mist.
A ground crew member held two eye-catching yellow and red flags, indicating that he could slide out. The L-15C Falcon, which had a sci-fi atmosphere on its fuselage, was filled with fuel, slowly slid out of the shed-style apron, turned right and drove into the continuous drizzle. Among them, drive smoothly along the apron area channel.
With the smooth shape of the canopy and the transparent rainproof coating on the surface, it can easily isolate the fine raindrops flying in the sky.
The wind was a bit strong, bringing with it a chill. This was caused by the sudden cold air.
Under the watchful eye of each ground crew member, the L-15C Falcon entered the taxiway smoothly, turned the corner, and stopped at the junction of the two roads. Zhou Hai quickly turned on his earphones, accessed the encrypted communication channel, and headed to the airport. The tower issued a takeoff request.
The female controller at the airport tower seemed to be a cute girl, her voice was still clear and sweet, and she gave a series of ground parameters and permission to take off.
"boom!"
The L-15C Falcon turned right and entered Runway 1. The roar of the engines became more intense. The two WS-17 turbofan engines increased from small thrust to medium thrust, providing a continuous source of energy for the aircraft.
After gliding for about 220 meters at high speed, the thin stream of water flowing on the L-15C Falcon fuselage disappeared unabated. It raised its nose and soared like an eagle, facing the cloudy sky.
"The weather forecast shows that cumulus clouds are at an altitude of 3,000 meters. Climb to 4,500 meters and recover. First, practice basic flight maneuvers." After the fuselage took off normally, Yang Xiaolong opened the tactical tablet terminal and clicked on the screen to obtain the latest weather forecast data. , issued new instructions to Zhou Hai.
"Yes." Zhou Hai heard the arrangement and kept climbing along the planned route.
Soon, just over thirty seconds later, the L-15C Falcon passed through layers of cumulus clouds, broke through the blockade, climbed to an altitude of 4,500 meters, and was greeted by the dazzling sunlight. There was a slightly gloomy atmosphere in the cockpit. The smoke disappeared.
Zhou Hai held the metal control column with a confident and calm expression. He released the control column, placed his left foot on the rudder, and began today's flight training.
To possess excellent flying skills, you need accumulated experience and hard training. Zhou Hai can fly as he pleases with the No. 6, but he cannot do that with the L-15C Falcon.
First, start with turning left, then turn right. The five basic flying movements are completed one after another without any feeling of unfamiliarity.
After completing the five basic movements for the first time, Yang Xiaolong did not shout to stop, and Zhou Hai silently repeated the flight.
Twice!
Five times!
Ten times!
Expensive aviation fuel continues to be consumed, and repeated training allows Zhou Hai to accumulate more and more experience, become proficient in operation, and become faster and faster in the five basic movements.
Thirty minutes later, Yang Xiaolong's steady and powerful voice rang out: "Okay, horizontal figure eights, oblique somersaults, high and low, and rollers."
"yes!"
Zhou Hai, who repeated the basic movements dozens of times without interruption, responded by controlling the L-15C Falcon, which happened to be in inverted flight, to roll to the right. After returning to normal flight, it turned right and circled.
Just like after flying a somersault on the horizontal plane, the L-15C Falcon flew forward, then turned left, flew in an arc, and pulled out another somersault.
In the sky at 4,670 meters, a horizontal figure-eight pattern appeared. The L-15C Falcon remained unabated. At a speed of nearly 400 kilometers per hour, it entered the front stage of the oblique somersault maneuver with a 45° tilt to the right.
After completing a tilted somersault, Zhou Hai then used the high-speed maneuver that Zhou Hai was most familiar with. He raised his head, climbed and rolled to gain a height advantage, and then traded height for a speed advantage.
At such an altitude, the L-15C Falcon's aerodynamic efficiency of the swept-back monoplane, flaperon and rudder is at its optimal level. Energy loss is almost unnoticeable during the climb, and it quietly performs dazzling high-speed maneuvers.
Finally, there is the simple and practical roller, which is both offensive and defensive, and combines the flight performance of the fighter aircraft with the wisdom of the pilot.
In less than a minute, a set of four basic tactical moves was completed. Yang Xiaolong still did not call for stop. Zhou Hai understood the meaning and carried out repeated training.
five minutes.
ten minutes.
thirty minutes.
By flying over and over again, Zhou Hai accumulated valuable flight experience at the expense of fuel consumption and flight wear.
Why do you say precious?
Because this one-hour basic movement and basic tactical flight training alone costs about 100,000 yuan.
RMB 100,000 per hour. Higher education aircraft requires graduates to fly 200 hours, which will cost 20 million yuan at this stage.
Yang Xiaolong's voice sounded on time: "Okay, put on your glasses and climb to 14,000 meters. High-altitude stall and tail spin subjects are very dangerous. I will show you how to correct it first, and you will do it again. Do you understand?"
"Understood." Zhou Hai took a deep breath and raised his head to operate the lever. The L-15C Falcon, which was in the middle of a roller maneuver, quickly changed its flight attitude and faced the sky higher above its head.
High-education aircraft students generally have to go to an altitude of more than 10,000 meters to train on stall and tail spin subjects. It is even said that the higher the better, because the higher the altitude, the greater the reaction time and operating space left for you.
In the stall spin state, its own speed is extremely low, and it loses altitude by about 100 meters per second. If it accidentally enters the stall spin at medium and low altitudes, there is a high probability that it will not be able to recover successfully because the reaction time is too short.
If there are no villages or cities on the ground, you must eject immediately to escape.
I'm sorry for the slow response. I have a ticket for reincarnation. If I'm lucky, I might get a good pregnancy.
