Soon, Yang Luo wrote the suicide note and immediately handed it over to Chief Engineer Wang. He turned around and wanted to go to the next door to change into his flight gear.

"Wait a minute." Chief Commander Wang called Yang Luo.

Yang Luo turned around in confusion and said, "Chief Commander, is there anything else?"

Chief Secretary Wang did not go to see the content of Yang Luo's suicide note, folded it and handed it to the assistant beside him, and said: "Since it's a test flight, don't wear your anti-lood suit. I'll prepare a new one for you."

As he said that, he took out a new anti-load suit that was still in the vacuum plastic packaging and handed it to Yang Luo, saying, "This is a special anti-load suit for the test pilot. Your anti-load suit can increase the overload by up to 2g, and this one is much better than yours. It can increase the overload by at least 3g, or even 4g, and the specific amount depends on the person."

"Thank you, chief tutor." Yang Luo was overjoyed. He took the anti-loo suit and rubbed his hands through the plastic packaging. He couldn't put it down. With this anti-loo suit, the 9g overload maneuver will not have black vision, and it may even challenge 10g.

"No need to thank you, I'm also trying to complete the test flight better." Chief Commander Wang said with a smile, "You have to keep it well. This uses a brand new high-end technology, with a low output and a value of 400,000 yuan per piece. Even the pilots of the J-20 use a lower-grade KH-9 anti-duty suit, and they are not qualified to use it."

"Don't worry, chief sir, I will keep it well." Yang Luo said seriously.

"After the mission is over, I will give you this anti-Dutch suit." Chief Master Wang smiled and said, "Go and change your clothes."

"yes."

Yang Luo was even happier, his steps were a little light, and he went into the dressing room next door to change his clothes.

Unexpectedly, when I came to perform a test flight mission, I could get a special anti-duty suit for the test pilot. In the flight army, this is the only one of the Scorpion cakes.

First put on the warm flight leather jacket and survival vest, then unpack the plastic packaging and put on the special anti-load suit for the test pilot worth 400,000 yuan. It is best to equip the Beidou locator, pistol, paratrooper knife, military mechanical watch and other equipment on your body, put the replaced training uniform, mobile phone and other items in the locker and lock it, and take the TK-10c helmet to return to the flight briefing room.

"Not bad." Chief Commander Wang looked at Yang Luo and said, "Today, the subjects we tested were very dangerous. They can be said to be one of the most dangerous subjects, with a low-altitude and high-speed speed."

Low-altitude large meter speed?

When Yang Luo heard that it was this subject, his face became very serious. He never expected that he would fly such a dangerous subject as soon as he came. This subject is indeed one of the high-risk subjects.

Flying at high altitude, even if there is a malfunction, even if the engine is turned off, at least it has altitude to deal with it. You can try to restart the engine. At the least, you can choose to jump, which greatly reduces the risk.

But low altitudes are not possible, especially low altitudes and large meter speed flights.

Let’s first talk about the definition of test flights for low-altitude large meter speed subjects. Low-altitude large meter speed means the maximum approximation value that can be achieved by flying out of the aircraft under the premise that the aircraft does not disintegrate.

The biggest danger of low-altitude large-meter speed test flight is not a fighter failure or an obstacle. The biggest danger is the disintegration of the aircraft. Once the aircraft disintegrates, at low altitude, even if the catapult is successful, the probability of survival is not high, and it is unknown whether there is a chance of catapulting...

During the test flight, there are many precedents for the low-altitude and large-meter speed flying, and the aircraft disintegration. The basic result is that the plane is destroyed and people are killed, and there is no way to come out.

Some people may ask, since you have to risk such a big risk, what is the use of this subject?

The current world pattern is basically guarded by various ground radars at high altitudes. If fighters want to avoid radar defense and break through the blockade line, they can only fly at ultra-low altitudes.

War is a race against time, and fighter jets cannot rush to the battlefield slowly, they must be at the fastest speed, and at this time, the low-altitude and large meter speed will play a role.

Only by flying out the low-altitude and large-meter speed limit of the fighter jet in advance can non-combat losses be reduced during wartime.

"The test flight site for the subject of low-altitude large meter speed is 200 kilometers northwest. There is a desert there, deserted and will not affect the people on the ground. It is also equipped with monitoring equipment." Chief Secretary Wang looked at Yang Luo and said, "The desert there is basically very flat, and the highest place is only twenty meters. Now we need to determine the altitude of the test flight."

By definition, flying at an altitude of 100m to 1000m from the ground or water surface is considered low-altitude flight. How high is the altitude of low altitude and high meter speed?

"Chief Commander, what is the flight altitude of low altitude and high meter speed during the J-10 test flight?" Yang Luo asked.

"The test pilot at that time was Li Zhonghua. He flew at an altitude of 1,000 meters. He first dived from a high altitude, then changed to horizontal flight at an altitude of 1,000 meters, and continued to accelerate. It lasted for twenty seconds, and the final speed reached 1,453 kilometers per hour." Chief Commander Wang seemed to have returned to the scene when the test flight was in the first test flight and said leisurely.

One thousand meters, one thousand four hundred and fifty-three kilometers per hour.

Yang Luo thought about it for a while, looked up at Chief Executive Wang and asked, "I don't dive from high altitude and accelerate, but I will directly accelerate in a level range, and fly for a hundred meters. How about it?"

One hundred meters, are you kidding, who dares to fly so low?

Hearing Yang Luo's words, Chief Secretary Wang's face looked a little ugly and said, "Yang Luo, this is not a joke, one hundred meters are too low."

Chief Secretary Wang's assistant looked at Yang Luo in front of him in surprise. He was young and had a very big tone. The senior pilots only dared to fly at a height of 1,000 meters. You just cut it to zero and wanted to speak, but he was not qualified to speak here.

"The limit of a thousand meters of air has come out. If the body materials have not been innovated, I believe I will not have better results if I fly. It is better to test flying at a lower altitude to see what kind of data I can get." Yang Luo said.

"No, this height is too low and too dangerous." Chief Master Wang shook his head.

The lower the altitude, the denser the air will be, the strongest the engine thrust, and the aircraft can fly out the maximum speed. However, the faster the aircraft speed and the greater the resistance it receives, the high-speed airflow will be like an increasingly sharp steel knife to "cut" the aircraft. If the aircraft is not strong enough, the shell will be pried up and the wings will be flattened.

A figurative metaphor is that it is like when we ride a bicycle in the wind, the faster we ride, the greater the drag. It requires the aircraft to fly at low altitude and high speed, which tests the ultimate strength of the aircraft structure and the maximum flight speed when it flies out at the extreme intensity.

"Chief Master, the lower the height, the more representative it is. Senior Li Zhonghua and I just happened to pinch the head and tail of the low altitude, and the maximum speed of a height between 100 meters and 100 meters can be calculated completely." Yang Luo continued to fly at an altitude of 100 meters.

Chief Master Wang looked at Yang Luo and asked very seriously: "Comrade Yang Luo, you have to think about it. If there is a problem at a low altitude of 100 meters, it will be doomed."

Yang Luo said firmly: "Chief Commander, I firmly believe that I can complete it. I think I have known me better than the Chief Commander. I dare to fly 700 kilometers per hour in the valley at an ultra-low altitude of 50 meters."

Although the dangers faced by ultra-low altitude penetration in the valley and large-meter-low altitude flying at 100 meters are different. One danger comes from obstacles and the other is the disintegration of the aircraft in the air, the difference is not large in terms of danger, and they are both very dangerous flights.

"Okay, since you insist, fly according to the height you said." Chief Secretary Wang nodded and said, "Once you find any problem, report it immediately and slow down."

"Yes." Yang Luo shouted seriously, "Please ensure that the task is completed."

"Go to the hangar."

Chief Secretary Wang waved his hand and took the lead in leaving the flight briefing room. He got into a commuter car waiting outside the door. The assistant next to him hurriedly picked up his briefcase, followed with Yang Luo, left the flight briefing room, and got into the commuter car.

After everyone got into the car, the driver started the engine, fed the fuel, and the commuter car started smoothly and headed straight to the hangar.
