Siheyuan: No One Can Be Left Behind

The meal ended in such a weird atmosphere. Li Dongfang originally wanted to stay, but was driven away by Minister Wang, who said that he was annoyed by the sight of him and told him not to come unless necessary. The scenery in the yard was nice, so he requisitioned it for his use.

Until he got back to the car, Li Dongfang felt that today's events were a bit fucked up. He didn't expect that things would be resolved like this.

After a few more days of busy work, the fighter was finally assembled and various related tests began.

The first thing to be carried out is the operational test of various parts of the aircraft, which basically will not cause any problems. Then comes the taxiing test. First is the low-speed taxiing, which is mainly to test the taxiing motion characteristics of the fighter, including the turning ability, the ability to accurately maintain straight taxiing and the ability to correct curve taxiing; then there is the medium-speed taxiing, which is mainly to check the fighter's structural strength and the working status of various systems under taxiing vibration conditions; the final high-speed taxiing has a very high risk level, as it is necessary to increase the taxiing speed of the fighter to the level where it can take off, but also try not to actually take off, but if the control is not good, it will really take off from the ground.

Fortunately, everything went smoothly and there were no accidents during the whole process.

Another week passed, and thanks to the mature technologies Li Dongfang used, all the tests went smoothly, which boosted the confidence of all participants.

Finally the time for the first flight arrived. It was a sunny day with no clouds in the sky, perfect weather for flying.

The airport was still heavily guarded, but today in addition to the staff, many high-ranking military officials were also present, even General He was here.

A relatively flat fighter plane slowly landed on the runway accompanied by two cylindrical MiG-15s.

First, the MiG-15 accompanying the observation took off, and then the new fighter slowly began to taxi. All the mounts on today's fighter were removed. This was to reduce the fighter's takeoff weight as much as possible, so as to minimize the takeoff ground speed and shorten the takeoff run distance.

As the fighter planes took off, cheers broke out at the scene.

However, Li Dongfang's expression was not relaxed. Instead, he stared at the fighter plane intently until the fighter plane rose into the sky in a stable posture. Only then did he feel slightly relieved.

The flight time for the first flight was set very short, basically just a takeoff and landing. The landing gear would not be retracted during the process. The fighter plane quickly turned around and landed steadily.

Li Dongfang finally breathed a sigh of relief. He had heard of too many accidents involving testing machines in later generations, and he had always been worried. It was not until now that he could finally let go.

General He and other leaders watched the entire test flight process and were very interested in the shape of the fighter plane. They kept asking people around them about the fighter plane.

Seeing the fighter plane land, Li Dongfang prepared to go back to check the flight data, as well as the photos taken by the accompanying fighter plane and the report on observing the fighter plane's flight posture.

Everyone else gathered in the direction of the plane, but Mr. He stopped Li Dongfang, patted him on the shoulder with satisfaction and said, "You're great, you got the fighter plane into the sky so quickly!"

Li Dongfang smiled and replied: "Boss, it's a bit early for you to praise us. The first test flight is just a basic test, and it's still a long way from true success."

Mr. He said unimpressively, "This is already impressive. I heard that the Russians are also developing new fighter jets, but it took them much longer from design to the first flight of the prototype than it did for us. You did a great job."

What I mean is that this is the final mass production technology that the Russians have developed after years of test flights and improvements. It is completely different from what they are still slowly groping for. As long as there are no problems with production and assembly, it will be easy to fly.

Back in the hangar, Li Dongfang looked at the relevant flight data and asked the accompanying personnel and the pilot about their feelings.

It cannot be said to be unprofessional, it can only be said to be completely unprofessional. After all, we don’t have professional test pilots now, and there is no perfect process and standard for test flights.

Now test flights all over the world are still based on feeling. After flying a few times and feeling that there are no problems, then it’s done.

However, as a person of later generations, Li Dongfang knew the term flight envelope.

The so-called flight envelope is to test the various limits of the aircraft. If the flight envelope is crossed, the fighter may suffer from operational loss of control, engine shutdown, structural damage and other malfunctions, so "red lines" must be drawn on the fighter.

Next, Li Dongfang prepared to conduct tests according to the flight envelope method. Of course, he would try his best to limit the test within the range of known data. After all, every one of our pilots is extremely precious now, and he does not want to risk their lives.

And we only have this one fighter plane at the moment. If something unexpected happens, we’ll be out of luck.

After calling together relevant personnel to discuss his ideas and finalizing the items for tomorrow's test flight, Li Dongfang returned to his temporary office. He wanted to sort out the items that needed to be tested in the flight envelope one by one.

When he wrote about the maximum speed test, he suddenly remembered the MiG-25's maximum speed of 3.2 Mach. This requirement for the pilot was not something that ordinary people could do, so he immediately found the test pilot to ask.

I learned that they also received relevant training, but there was no unified standard, so I don’t know how many Gs of pressure they can withstand.

Li Dongfang had no choice but to report to his superiors and select some pilots with good physical fitness to participate in the test flight. Otherwise, the pressure of 8G would make most people faint directly, which would be fatal during the flight.

After dealing with this matter, Li Dongfang couldn't help but shake his head. Although he was not professional in test flying, with the knowledge he learned in later generations, he actually knew more than the most professional people today. He couldn't help but sigh that the development of various technologies in later generations was really fast.

Li Dongfang raised his head and looked outside, only to find that it was already dark. The workers had all returned to the dormitory. Now there were only armed guards patrolling in the hangar.

"Lin Shu, this girl, didn't even call me for dinner. I must find a chance to deal with her later." Li Dongfang muttered as he walked out of the hangar.

As soon as I came out, I saw Lin Shuzheng moving a stool and leaning against the jeep, leisurely eating melon seeds. There was also a cup of tea on the hood, which looked very refreshing.

Only when she is here does Lin Shu feel the most relaxed. Only here does she not have to worry about Li Dongfang's safety.

When Lin Shu saw Li Dongfang, he immediately stood up, patted the melon seed shells on his body, then picked up the teacup in one hand and carried the stool in the other and ran to the duty room.
