Chapter 681 A dark military plane crashed at our airport
The nearest third-rate airport has the most obvious target features. The airport is very large and can be detected visually from a long distance. After entering the plain area, the visibility has been greatly improved, although the sky is still gray because of the heavy clouds.
The reason for the high visibility is good at mid- and low-altitudes.
Li Zhan found that the plane continued to decline, and the descent rate remained at 3 meters per second. No matter what he did, the plane would maintain this descent rate. His altitude was 1,200 meters, the airspeed was 1,100 kilometers per hour, and he was about 60 meters away from the third-rate airport.
kilometer.
In other words, the plane will descend to an altitude of about 600 meters when arriving at the third-rate airport.
He still has about 600 meters of ground altitude, which is enough for an emergency landing. The problem is that he is not sure whether the descent rate will continue to increase. If the descent rate is increasing, he will crash before reaching a third-rate airport.
.
What's worse is that when the aircraft descends autonomously, it means there is a problem with the flight control system. There is nothing worse than losing control of the aircraft. The pilot uses the flight control system to impose will on the aircraft, and the flight control system appears.
The problem means that no matter how good the pilot is, he cannot make the plane fly completely according to his own will.
Li Zhan made a blind call while concentrating on controlling the plane to fly to a third-rate airport, praying in his heart that the plane would not have any new problems.
Things often don't go as one wishes at times like this. The moment Li Zhan entered the city, a new fault occurred in the power system!
The engine speed did not change and remained at half power, but Li Zhan clearly felt that the airspeed was decreasing. When he looked at the airspeed indicator, the airspeed was dropping rapidly. After checking the fuel, he found that it was not a fuel problem.
The war horse immediately concluded that there was a new problem in the power system.
The airspeed dropped very quickly, to 600 kilometers per hour in the blink of an eye. Flying at this speed, and based on the aircraft's current rate of autonomous descent, he would not be able to fly to a third-rate airport.
He quickly pushed the bottomed throttle lever halfway forward. The airspeed indicator dropped slower, but still continued to drop. Is there an oil leak? This possibility is unlikely. There is no oil leak.
It will affect the performance of the engine.
The power system was completely abnormal, and Li Zhan hesitated.
The throttle lever has obviously regained some response. This is proved by the fact that the airspeed decrease rate has eased after pushing the throttle lever. However, Li Zhan is hesitant about whether to push the throttle lever to the end. If the abnormal power system surges again,
As things get worse, the situation will only get worse.
Below is a dense urban area, with various high-rise buildings, various residential buildings, and many schools, all of which are densely populated areas. The flight altitude has dropped to seven or eight hundred meters, and he can even clearly see a school not far away.
There are a large number of students playing sports on the school playground.
It is now 10:30 in the morning, the official time for recess exercises.
what to do?
If it were an ordinary fighter plane, he would not hesitate to avoid these areas and fly to the suburbs and some remote airports for emergency landing. But now he is flying a prototype of a fourth-generation aircraft. The value of this aircraft lies in the cohesion of the aircraft.
It is the result of decades of hard work by scientific researchers and is an important sign that the People's Air Force has entered the world's strongest air force club.
He knew very well that everything Black Ribbon No. 01 experienced today would provide a large amount of valuable test flight data for the scientific research team. Many of the movements and postures experienced were almost impossible to fly in normal test flights. Even Li Zhan
It's also difficult to fly out.
Various coincidences allowed Black Ribbon No. 01 to experience many things that would not be experienced under normal test flight conditions, and these are crucial to determining the flight envelope of a new model of aircraft.
The palms and backs of my hands are full of flesh, so it’s very difficult to choose.
After hesitating for a moment, Li Zhan decided to make an emergency landing at the third-rate airport as planned. The main reason was that the plane was still controllable. The area around the third-rate airport was relatively remote. As long as he entered the area where the airport was located, he would have more leeway.
After making up his mind, he pushed the throttle lever all the way down.
The worst-case scenario has indeed occurred. The airspeed of the aircraft has increased significantly, the acceleration is very fast, and the engine power has reached its highest level in a very short period of time, pushing the aircraft forward. The advantage is that Li Zhan can control it under the influence of the rudder.
The downside is that he has no way to control the power system.
When the plane was approaching the airspeed of 1,000 kilometers per hour, Li Zhan took away all the throttle levers and shouted expectantly in his heart: Slow down, slow down, slow down...
The plane slowed down.
Li Zhan immediately grasped the pattern. When the airspeed dropped to a dangerous value, he pushed the throttle lever all the way, the engine ran at full power to accelerate the aircraft, and then closed the throttle to slow down. He just moved quickly and slowly towards the third-rate airport.
In the urban area, many people saw the dark fighter jet flying at low altitude and high speed. Those who cared about military news could immediately recognize that it was a fourth-generation aircraft that had successfully made its first flight, while those who did not care about military and national affairs were attracted by the low-altitude
The phenomenon of high-speed flight attracts attention.
While flying over the side of the playground of a primary school, at a flying altitude of about 500 meters, Li Zhan saw the pupils on the playground happily waving to him in the Young Pioneers salute. An ordinary and simple gesture
This move greatly boosted Li Zhan's confidence for no reason. He took off his oxygen mask and pushed his goggles up. His extremely handsome face had a resolute expression.
He was very calm and keenly discovered that the fuel consumption of flying like this was very considerable. After a quick calculation, he came to a gratifying result - the fuel had just run out when he arrived at the third-rate airport. To make a successful emergency landing, the final step was to
The key issue is getting the plane to stop.
When the power system fails, the only solution is to use aviation fuel.
In a not-so-good situation, after calculation, the plane's airspeed would reach 800 kilometers per hour when it arrived at a third-rate airport. It was absolutely impossible to make a successful forced landing at this airspeed, so Li Zhan had to make some risky moves.
The radar of the airport tower finally detected the No. 01 black ribbon, and the distance had shortened to ten kilometers. This distance had entered the control range of the tower.
The controllers watched in surprise as a dark military plane rushed over at lightning speed, suddenly rolled at seven kilometers, and entered the landing route. Careful people found that the small wings on the military plane were facing the direction of the nose.
, obviously this is a deceleration angle.
Decelerating by barrel rolling at an altitude of three to four hundred meters is the most effective deceleration method that Li Zhan can think of and can achieve at this time. When the aircraft barrel rolls, it will consume a lot of kinetic energy and the flight speed will continue to decrease. Usually when doing this
When maneuvering, the pilot will give more fuel to maintain airspeed.
However, the risk of operating an aircraft with many malfunctions in a barrel roll at this height is extremely high. If he is not careful, Li Zhan will not even have a chance to parachute. During the barrel roll, the direction of the aircraft's nose is constantly changing, and the pilot must
Keep the aircraft flying straight through constant maneuvers.
The principle of using barrel roll to avoid attacks is to continuously destroy the flight trajectory.
Li Zhan resumed level flight at an altitude of about fifty meters above the ground. From a distance, it looked like the wingtips were almost touching the ground.
Black Ribbon No. 01 landed. The landing gear was extended early to slow down the aircraft. After the main landing gear touched the ground, the ground monitoring instrument detected that the landing speed of the aircraft was 512 kilometers per hour.
"The landing speed is too fast!" a controller exclaimed.
The chief controller quickly asked the prepared emergency rescue team to adjust their positions and drive all to the end of the runway. Obviously, the runway of more than 3,000 meters may not be enough!
Passengers waiting in the terminal also saw it. The dark military plane almost hit the runway. It was so fast that no one with common sense would know that the plane would not be able to stop after landing like this. They opened their mouths wide.
I stared blankly at the dark military plane running towards the end of the runway like a wild horse that had escaped the reins.
Li Zhan hit the brakes.
The landing gear tires locked up, then melted rapidly under the fierce friction and burned. Then the wheel hub touched the ground, and sparks burst out from the violent friction between the metal and the runway surface. All measures were used, and the plane was still running at high speed.
The speed reached 325 kilometers per hour.
The vertical tail, flaps, canards and even the tail were all in the best positions, but the aircraft landed too fast.
Li Zhan stared ahead coldly. On the right taxiway were dozens of rescue vehicles with flashing lights and sirens, also running towards the end of the runway.
Under the current situation, it is almost impossible for the aircraft to stop before the runway is used up.
Li Zhan gritted his teeth and refused to do anything else. He decisively opened the canopy!
The canopy opens backwards. When the canopy is opened, it acts as a huge speed brake, instantly providing huge resistance!
The fierce wind blew in, and Li Zhan's face was blown out of shape, and he even breathed the sultry air outside. Fortunately, the speed of the plane dropped significantly, and the number quickly dropped to 200 kilometers per hour, and then the speed of decline
Speed up until it comes to a complete stop.
There are several hundred meters of runway ahead.
Li Zhan quickly shut down the engine, and only after confirming that both engines were shut down could he completely let go of his hanging heart.
Taking off his flight helmet and taking off his starched white labor protection gloves, Li Zhan took out a crumpled cigarette from his pocket, took out one and lit it with a lighter, completely relaxed and smoked comfortably against the back of the seat.
Hua Zi.
The airport emergency rescue team arrived. The on-site commander jumped down from his boss and saw this scene. He was immediately shocked. Isn't that awesome?
He could think of ways to use the canopy to slow down, and even smoked Huazi after it was done.
Li Zhan waved his hand to the on-site commander, signaling them not to get close. The plane was not in danger of a second disaster, and it carried neither ammunition nor aviation fuel, so Li Zhan was very relieved.
Under the condition of ensuring safety, he could not let others get close to the world's most advanced fourth-generation aircraft.
