Just after the National Day, last night, the test base ushered in the heaviest snow since the beginning of winter. At 5:30 in the morning, the field support team entered the outfield with snow clearing machinery to clear the snow in the simulated deck area.
The Meteorological Department reported that there will be no snowfall during the day today, with northwest wind at a speed of 5 meters per second.
At 7:30, the ground support team entered the scene. Today, the arresting landing test will be carried out. The department responsible for the arresting cable is ready to check the arresting system repeatedly.
Fang Juemin arrived at the simulation deck area early and checked the arresting system in detail. The electromagnetic ejection system and the arresting system were developed by two different teams. However, according to Fang Juemin, the two systems should be integrated and should be called
Aircraft carrier take-off and landing system, including landing assist lighting system, etc.
There are several teams in the test base doing test flights, electromagnetic catapult systems, arresting systems, new Flying Shark fighters, newly modified engines, etc.
The inspection report came out two days ago. It was found that the avionics system of J-15S No. 583 was affected by bad weather, the ground height sensor failed, and the erroneous data occurred just before the landing gear of the aircraft was about to touch the ground. It was very unusual.
Danger.
The experimental training team is using an undetermined model of aircraft. If there are problems with various systems of the aircraft, it will not constitute an accident as long as it is not caused by human factors.
The J-15S team, together with the avionics system team, worked hard for more than ten days to solve the operation problems of some sensors under severe weather conditions. All four J-15Ss can be used for test flights normally.
In the flight briefing room, a dispute broke out within the experimental training team.
After Zhu Wei read the training arrangements, he said to Li Hai firmly, "Adjust the order. I will go first, Luo Xun second, you third, Party for the People fourth, Zhao Feiyan fifth, Zhan Yuntian sixth
, Mao Lele seventh."
"Team leader, I'll fly first, and I'll let you arrange the rest." Li Hai disagreed, and his attitude was equally firm.
Zhu Wei made a rare speech and said without any refutation, "I am the team leader, carry out the orders!"
Li Hai wanted to speak, but Luo Xuan glared at him and said seriously, "Li Hai, do you want to disobey me?"
Li Hai gritted his teeth unwillingly and said, "Although my flight time on the ship is not as good as that of the team leader, my skills in arresting and landing the ship are top-notch. I am the most confident if I fly first! The most reliable.
It will be beneficial to subsequent test flights.”
"You think too highly of yourself." Zhu Wei waved his hand, "That's it, execute the order!"
Mao Lele, who was sitting below, was dumbfounded. She couldn’t understand why they were quarreling so much over the fight to be the first to fly. The team leader was a very nice person, and he was definitely not someone who wanted to take credit. Li Hai was not the same, and Li Hai was
Hai has made countless achievements, and there is no need to quarrel with the team leader over this first place.
After the briefing, the group of people walked out.
Zhao Feiyan whispered to Mao Lele, who was full of doubts, "The first person to test flight was to go to the mine."
Suddenly, Mao Lele suddenly realized and felt ashamed of his previous random thoughts.
Zhu Wei and Li Hai are competing to do the most dangerous work.
Zhu Wei has basically handed over the experimental training work to Li Hai. He rarely interferes in Li Hai's training organization. Today, he rarely uses the title of team leader to pressure people, in order to grab the most dangerous jobs.
The ground support team was ready, and the seven fighter jets of the experimental training team also completed their assembly on the taxiway in the posture of an elephant strolling. They then entered the simulation training area and lined up on the taxiway outside the deck to wait.
For safety reasons, there cannot be any fighter planes within the deck. During the test flight, anything may happen.
Zhu Wei piloted the fighter plane into the take-off position and soon let it fly.
Waiting for Li Hai and others in their respective fighter cockpits, their eyes followed Zhu Wei's No. 581 J-15S.
Everyone knows that the key is landing.
For carrier-based pilots, the most difficult thing to obtain is ship landing qualification, which is also the last step to become a qualified carrier-based aircraft pilot.
Zhu Wei is a first-generation Flying Shark pilot. He has served as captain on an aircraft carrier and is one of the veterans with the most experience in carrier-based aircraft flying in the Navy.
To be fair, in terms of experience and technology, Li Hai cannot be said to be comparable to him.
Zhu Wei flew around the base for fifteen minutes. The fighter plane had completed its warm-up and entered the landing route according to ground instructions.
The arresting system has been on standby for a long time.
Zhu Wei descended in a textbook manner without swaying or swaying. He carefully manipulated the joystick, fine-tuned the fighter's attitude, maintained its takeoff speed, and "smashed" toward the deck runway at a larger angle.
Different from land-based fighters, carrier-based fighters must come down in a take-off attitude when landing on the ship. Once the lanyard fails, the pilot must respond within one second to perform a go-around, which requires that the fighter aircraft must be in the take-off attitude.
Before completing the lanyard, always maintain the speed, flap angle, elevation angle, etc. required for the go-around.
From the outside, the land-based fighter jet appears to be landing very smoothly, just like pushing a rowing boat from the shore into the water, gliding along the runway and using a parachute to shorten the whole process.
When a carrier-based fighter jet lands on a ship, it really hits the deck. As a result, higher requirements are put forward for the aircraft carrier deck, arrester retraction, fighter aircraft structural strength, landing gear strength, etc. Take the J-11
The J-15 based on this is no less difficult than designing a new fighter jet.
No. 581 J-15 was getting closer and closer to the runway, and everyone's hearts were in their throats.
As the main landing gear of the fighter plane hit the runway heavily, everyone's pupils were at their maximum. The tires of the main landing gear splashed up two clouds of snow mist, and the tail hook successfully hooked the second arresting cable. The arresting system worked, and on
Stop the fighter at a set distance.
The fighter plane stopped, and everyone breathed a sigh of relief.
A successful operation with a perfect score shows Zhu Wei's strength.
The arresting system team quickly inspected the equipment to ensure that all subsystems were operating normally.
Ten minutes later, the rest of the crew lined up to enter the ejection take-off position for their first arrested landing training. Zhu Wei made a good start and gave everyone confidence.
Li Hai was assigned to the last one as the first round of ship landing training skills.
The blocking system is a new type and has not been tested in real machines before. There is no actual data on everything. Whether it can be blocked and whether it can reach the specified number of repeated uses is unknown.
Therefore, the first pilot to fly has the greatest risk, followed by the last pilot to fly. The arresting system used by the foreign military requires a relatively long cooling time to return to normal use after receiving a certain number of fighter aircraft in succession.
.
The performance of the arresting system used by our army on the No. 1 and No. 2 ships is almost the same as that of the foreign military. However, the one being tested is different from the times. It is only a system that uses electricity as power.
A technology is a gap of an era.
Li Hai ejected and took off, flying around the field step by step to warm up the fighter plane. In winter, the power system and flap system of the fighter plane are greatly affected by the weather, so sufficient warm-up flight is necessary.
Unexpectedly, as if to make it more difficult for you, when he was flying around the field for the second time, it suddenly snowed. Li Hai clearly saw the snowflakes falling on the windshield and quickly turning into water and scattering against the glass surface.
Fly away.
When I looked at the temperature outside, it dropped sharply to below zero.
Li Hai decisively activated the de-icing system. If the flaps were frozen, it would be no joke. There was an accident in which the aircraft's flaps froze due to a sudden change in air temperature, resulting in a crash and the death of more than 20 people.
Senior engineer.
In the history of world aviation, accidents caused by sudden changes in air temperature abound, and wing de-icing was once a world-class problem.
Before the second lap was completed, Li Hai discovered that the sudden snowfall was not simple, and it actually formed a localized blizzard in a very short period of time.
People in the tower and the simulated deck training area were also confused. The sudden change in weather did not give everyone any time to react. It was like a child's face, changing at any time.
Zhu Wei, who had left the plane and was waiting for Li Hai to land on the side of the runway, turned around and ran to the jeep without saying a word, asking the driver to take him to the tower. Dang Weimin and others ran into the ground support vehicle with solemn expressions.
Looking from the ground to the sky, there is no trace of J-15S No. 583.
The blizzard was like a heavy rain, and the visibility was suddenly less than 50 meters. Even the car soldiers driving towards Tata had to slow down their speed.
"What's going on at the meteorological station? There was no warning for such a drastic weather change." Zhao Feiyan said with dissatisfaction.
Dang Weimin said in a deep voice, "I'm afraid they were also caught off guard."
Luo Falcon is more calm. He is also one of the first batch of Flying Shark pilots. Like Zhu Wei, he was selected from the Air Force. Whether he served in the Air Force or later joined the Flying Shark Force to conduct J-15 fighter testing
During training, including later training at sea, this group of people encountered too many sudden changes in weather.
The most dangerous time was when the No. 1 ship went to the Western Pacific for combat training for the first time. One afternoon, the aircraft carrier received the last batch of four fighter jets as planned. The weather in the sea area where it was located at that time changed rapidly. The sun was shining brightly.
It only took a very short time for the clouds to reach a dense density and then it started to rain.
When the last fighter plane entered the landing route, the rainfall escalated into a heavy rainstorm. According to the data monitored at that time, the rainfall was as high as 20 millimeters per hour, and the standard for a heavy rainstorm was 14 millimeters of rainfall per hour.
Let alone the visibility at that time, when a person stood on the flight deck and stretched out his hand, his fingers would be blurry!
The most terrible thing is that after the last fighter plane hovered in the sky for half an hour, not only did the rain not let up, the wind even showed signs of increasing, and the fuel dropped to the bottom.
At that time, the command team made several plans. If the rain did not improve, the fighter jets would be decisively abandoned, but the pilots and the aircraft carrier must be saved. If they risked landing on the ship, under the circumstances, the pilots would not be able to see the ship island or the fighter aircraft's avionics system.
Errors may also occur due to the influence of bad weather. Once a fighter plane hits the island, the losses will be heavy.
The pilot of the last fighter plane was Li Zhan. At that time, he took the initiative to face the difficulties and land on the ship. He used a laser to mark the location of the ship island. He was confident of aiming for the landing runway. If the arresting wire could not be attached, he would try again during the go-around phase.
It’s not too late to abandon the plane and skydive.
Li Zhan succeeded in the first attempt, and he accurately hooked up to the second blocking rope. His movement was more than perfect. At that time, Li Zhan had not long been transferred from the Western Eagle Falcon, and his one-hand operation directly established his position in the Flying Shark Troops.
Now, the situation that Le Hai is encountering is very similar to the situation that his master encountered at sea.
After Luo Shun told everyone about the case from that year, he comforted them and said, "At that time, Mr. Li was at sea to deal with emergencies. We are on land, and Li Hai's conditions are better. If it doesn't work, just abandon the plane."
Skydiving, Li Hai will be fine."
After listening to Luo Falcon's words, Dang Weimin and others relaxed their tense nerves a little. Luo Falcon was right. If it doesn't work, just abandon the plane and parachute. There are not many airplanes, and the current test flight synchronous monitoring and transmission technology is advanced, even if
Even if the aircraft is gone, the specific data at that time can still be obtained, and it will not have much impact on the test flight of the new fighter aircraft.
Li Hai didn't think about his own safety at all, and now immediately measured his blood pressure and pulse etc. The data was not much different from sitting there drinking tea and chatting.
Moreover, Le Hai also thought about the situation at sea.
In fact, the weather at sea is more changeable, and there are often violent storms here and beautiful days in the sea dozens of kilometers away.
In other words, sudden weather changes at this time may not be a bad thing for experimental training.
Li Hai turned his head and glanced at the ground, but couldn't see anything. Everything he saw was white, and the slightly shaking fighter plane reminded him that the automatic trimming system was constantly working to correct deviations caused by turbulent airflow.
He turned off the automatic trimming system and switched to manual control. He performed subtle operations through prediction and maintained the attitude of the fighter. The automatic trimming system is a "post-event correction" and will only intervene when the attitude changes. The pilot performs operations based on experience.
Anticipatory operation can prevent the fighter aircraft's attitude from being affected.
The J-15S used by the experimental training team is equipped with more sensors, so that more data can be transmitted back to the location in real time, making the acquisition of these data more stable.
After Zhu Wei entered the tower, he quickly observed various parameters of fighter No. 583 in the air. The changes in these flight parameters meant that the fighter was flying southward from the northwest of the base.
"Dong San, this is Dong Yao. You haven't deviated from the route. Keep your attitude and fly for another five kilometers. You should be able to see the runway." Zhu Wei took the microphone and guided Li Hai to operate.
Li Hai said, "Dongyao, I want to continue to prevent the landing."
"This..." Zhu Wei was stunned for a moment.
Li Hai said, "Such sudden weather is rare, and we can definitely use it to conduct ship landing tests under severe weather conditions. I am confident that the go-around will be smooth."
What Zhu Wei wanted to hear was the last sentence. He quickly checked the trend of weather changes, and found that it would only get worse, not better.
"Okay, no matter whether it works or not, it's just one time." ()
