Li Hai, who was within ten meters above the ground, could not see the light signal of the landing assist system at all, which showed that the assist landing system was unable to function in the current extremely bad weather.
If it was a routine landing, Li Hai would have enough time to choose whether to continue landing or go around, but he would only have one chance to continue an intercepted landing.
He took off his oxygen mask, pursed his lips tightly, half of his attention was on the flight data, and half of his attention was on the front.
The low-altitude airflow became more unstable, and bursts of turbulence hit, causing the fighter plane to shake violently. Li Hai needed to constantly control the steering column to maintain its attitude, but the fighter plane's attitude was still crooked, and the nose of the plane veered to the left for a while.
Sometimes it leans to the right, sometimes it tilts 45 degrees to the left and faces the runway, and sometimes it tilts 45 degrees to the right and faces the runway.
The flight altitude continued to decrease. In order to control the flight attitude, Li Hai did not lower the landing gear at the specified node as required by the operating regulations. He had to wait until he saw the light signal of the landing assist system.
People in the tower could only see the green dot representing No. 583 J-15S from the display. Even with the most advanced telescopes, they could not see the current posture of the fighter through the thick blizzard.
Zhu Wei was anxious in his heart, even though he was calm and calm on the outside.
The commander had no way to provide effective guidance to Li Hai and could only rely on Li Hai himself.
The visibility at this time is almost zero, and there is a vast expanse of white in front of you. If you stare at it for a long time, it is easy to create the illusion that the world is turned upside down.
Li Hai simply focused his attention on the three displays. At this time, he could only fully trust the data provided by the various sensors of the aircraft and adopt an instrument landing method to land.
After the flight altitude dropped below 100 meters, the airflow became increasingly unstable and the plane shook violently.
Li Hai kept manipulating the joystick, back and forth, left, right, and left, with irregular amplitudes. Even if he controlled it with all his strength, he still could not keep the fighter aircraft stable.
He tried to adjust the nose of the plane that was tilted to the left back to the runway, but found that once it was too far, the plane showed signs of stalling.
As a last resort, he could only keep the nose of the plane tilted to the left, but the plane actually flew toward the runway crookedly.
It's like being blind in your left eye on an airplane and you need to turn your head to the left to see the road with your right eye.
The opportunity to land was fleeting. No matter which arresting rope it was, as long as it could be hooked up, the adventure would be meaningful. He had almost no energy left to communicate with the tower. At this time, it was as if he had become one with the fighter plane.
Every tactile sensation is feeling the posture of the fighter plane.
The pilot's feeling is very important. During the long years of driving, feelings will arise between man and machine, and this will definitely be the case. Compared with cold data, in some special times, pilots are more willing to believe in their own feelings.
The feeling can not only lead the pilot out of trouble, but also accelerate the pilot into an abyss.
The tail hook had been lowered. A few seconds later, Li Hai felt a powerful impact. At the same time, the landing aid signal light on the left flashed past. Almost at the same time, the airspeed increased in just two seconds.
It dropped from 280 kilometers per hour to zero.
The huge inertia caused Li Hai's upper body to rush forward, and was then firmly held by the safety belt. After the fighter plane stopped, his back leaned heavily on the back of the ejection seat.
The ground staff were dumbfounded. They didn't have time to think about it and subconsciously rushed forward.
Just now, they probably saw a scene that they were unlikely to see for the second time in their lives. Fighter No. 583 rushed over at an angle, with the airspeed much higher than the prescribed speed, and it was so shaky.
It hit the position of the blocking cable, and the tail hook actually accurately caught the second blocking cable.
A special tractor for the aircraft carrier deck worth tens of millions drove over, hooked up the nose landing gear of the No. 583 J-15S, and quickly towed it toward the hangar. The rest of the people, etc., all took commuter cars to evacuate the outfield.
The ambulance team received the order and rushed to the hangar. When the medical staff rushed over, Li Hai was getting off the plane. The medical staff were stunned. Didn't they say that the situation was serious? It's not like that. It's hard to get off the plane by yourself.
?
The people on the tower were crazy with worry, so they naturally came up with a plan based on the highest level. As soon as the medical team heard that the situation was serious, they thought it was a serious condition and sent all the ambulances and medical staff on duty at one go.
There was a scene where dozens of medical staff stood there with various first-aid equipment and stared dumbfoundedly at Li Hai as he steadily walked down the boarding stairs...
Chaos is certain.
After the blizzard raged for a full six hours, a report came from the weather station - the most intense snowfall in the past thirty-five years.
The next morning, the base informed all personnel to bring their tools and participate in snow removal.
When Li Hai and others arrived downstairs, they discovered that the snow was half a meter thick. With such thickness of snow, it was difficult for the snow plow to operate!
From morning to night that day, the entire base was clearing snow. At night, various support vehicles were still cleaning up the outfield in order to resume training the next day.
The test training team, together with the R&D team, concentrated their time on studying the various data recorded during Li Hai's blocked landing. Such data is extremely valuable and can form pilot landing operation guidance under the same circumstances.
It seems that because of this incident, the Navy Headquarters has increased its requirements for the experimental training team. In Li Zhan's words, if you don't demonstrate extreme operations in experimental training, are you going to let the brothers on the front line take risks in combat?
Heartbreaking words.
When the experimental training team took out the various parameters that prevented landing in the Lehai blizzard and held an analysis meeting, everyone gasped frequently.
Judging from the data, Li Hai's fighter plane almost hit the runway, and the faults in the flight parameters were very obvious. This also reflects that the strength of the J-15S's landing gear structure is very sufficient.
The technical team analyzed various parameters and concluded that the newly modified Flying Shark has withstood the test of the harshest climate and met the design standards.
At this moment, Li Hai suddenly asked a question.
He looked at the technical team and said seriously, "Everyone, when I was controlling the landing of the fighter plane, I vaguely felt that the flight control system had deviated from the command track."
"There is no problem with the flight parameters, and there is no problem with the data collected by the sensors." Tang Feilin, who is in his forties and is responsible for the newly modified flight control system of the Flying Shark, immediately answered.
He is a second-generation flight control expert who introduced Su Liangqi in his early years. When Shen Hoy copied the aircraft, he was a young man who had just graduated from the factory and was assigned to the flight control team. Later, when he was working on the J-15, he Transferred to the flight control team of the J-15 project.
I have been working on the flight control system of the J-15 series for half my life. I have been doing this for more than 20 years, and now I am the chief engineer of the J-15 flight control system.
Li Hai carefully considered his words and said, "Mr. Tang, I know there is no problem with the data, but my personal feeling tells me that the Feikui system is running on the verge of losing control. I can't explain the specific reason, it's just a feeling."
This is so unconvincing.
Without any data support, it is too reluctant to judge that the flight control system, which has been developed and improved over the past twenty years, is out of control by just feeling!
Since Zhang Chao's incident, the Navy has expressed strong dissatisfaction with the flying shark's flight control system. Shen Hoy and the research institute made up their minds to make major improvements, and put down their big brother airs to ask Cheng Luoma and the research institute there for advice.
After improvements, the Flying Shark fighter never had any problems with its flight control system.
The newly modified Flying Shark uses the latest improved flight control system.
At this time, Zhu Wei interrupted and said, "Okay, the analysis meeting will start here."
Everyone understood and stood up to leave.
Soon Zhu Wei, Li Hai and Tang Feilin were left in the conference room.
Tang Feilin was very dissatisfied. What is a sign of deviating from the order track? In plain language, it means losing control. This "crime" is too big. If you say it without any basis, everyone will be angry.
Zhu Wei said, "Li Hai, you can't convince people just by feeling. Are there any other symptoms?"
Tang Feilin also looked at Li Hai and said, "Captain Li, I believe in the pilot's feelings. Likewise, I also believe in the data."
His subtext is that he believes in data more. This is correct. What can technicians rely on if they don’t rely on data? It’s useless to talk about it. Only when the design index data can be actually shown can it be real.
Lehi was not unprepared.
In the eyes of others, he had just escaped death, completed an arrested landing under absolutely impossible conditions, and even attached a second arresting rope. After experiencing such an incident, his body and mind were already in a state of relaxation and adjustment. state, there must be a recovery stage.
But for Li Hai, who had experienced more severe weather and tsunamis in the South China Sea, the Sulawesi Sea, the Western Pacific and other waters, such things were really difficult to shake his tenacious nerves.
Therefore, after landing, he immediately reviewed the entire process in his mind, and then the feeling of uneasiness became clearer and clearer. After careful analysis, he found that the feeling of uneasiness was not due to the bad weather, but from On fighter planes.
After repeated review in his mind, Li Hai almost concluded that his feeling was right, but the data obtained could not support his point of view.
He put it forward at today's meeting without too much hesitation. No more comrades should die because of an out-of-control fighter plane.
Li Hai said slowly, "Mr. Tang, I have no intention of questioning the military personnel's efforts. Let's just discuss the matter."
"Captain Li, it is the principle of our military technical personnel to discuss matters as they arise." Tang Feilin immediately expressed his understanding.
Li Hai continued, "Okay. Although there are no clues in the data of this flight to support my judgment, I still insist that the flight control problems of the old Flying Shark have not been completely solved in the new Flying Shark."
"In other words, our Flying Shark has had this problem since the day it was born, and it has spread to the new Flying Shark..." (End of Chapter)
