Great Power Fighting Falcon

The throttle lever on the left was pushed to the front. After the speed came up, Li Zhan released the brakes and the fighter began to accelerate and slide forward. He stared at the speedometer, and after reaching takeoff speed, he quickly pulled back the throttle lever, raised the speed brakes, raised the flaps, and started decelerating with the tire brakes.

The fighter plane taxied forward for almost a thousand meters before slowly stopping. Li Zhan slid to the taxiway next to him and reported to the tower, "Tower, all my systems are normal. Requesting a test flight, completed."

"Dongyao can be tested and checked again for safety. It's over." Xue Xiangdong agreed to Li Zhan's request.

"Dongyao understands."

Li Zhan returned to the take-off position and once again checked the various systems of the fighter, especially the flight control system and power system. The former is the most affected, and the most critical is the latter, which is the top priority among all systems of the fighter aircraft.

After confirming that everything was normal, Li Zhan began to take off.

Maximum throttle, flaps in the take-off position, release the brakes, and pull up to climb.

The moment after leaving the ground, many people felt relieved. Especially the officers and soldiers in the repair shop and maintenance brigade. The aircraft has been repaired, but they are not sure whether it can fly normally. As long as the plane flies, it is more than half successful. That's why the first flight is so important.

"It feels very raw and a bit unnatural, like a car whose four-wheel alignment is not done properly." After climbing to 3,000 meters, Li Zhan said carefully before choosing his words.

Every ground-air dialogue is recorded, so every feeling and opinion raised by Li Zhan during the flight will be recorded for later analysis.

"Dongyao, how is the attitude of the fighter plane? Is the flight control normal?" Xue Xiangdong asked.

Li Zhan replied, "The posture is quite stable and the flight control is fine. It's over."

"Dongyao, standard test flight procedure, feel free to express your feelings, over." Xue Xiangdong ordered.

"Dongyao understands."

Li Zhan continued to climb to an altitude of 8,000, and could not go any higher. Because it was a test flight, the safety altitude was very important. Oxygen becomes very thin after 4,000 meters, and pilots need an oxygen supply system to maintain breathing. Therefore, after Li Zhan flew a certain distance at 8,000 meters level, he quickly dropped to below 4,000 meters and circled around the station.

More than 20 minutes later, Li Zhan asked the tower for instructions, "Tower, I'm going to do some maneuvers to comprehensively test the aircraft's control system. It's over."

After nearly half an hour of flight, no problems occurred, indicating that the repair of the fighter aircraft was successful and basically met the delivery standards.

Xue Xiangdong had no reason not to agree. He said, "Dongyao, you can do some maneuvers, but don't do large overload maneuvers. That's it."

"clear."

Li Zhan began to perform simple maneuvers, from an altitude of four thousand meters to less than one thousand meters. When a fighter aircraft maneuvers, except for diving, it is basically a process of losing energy, so altitude is required to maintain it.

After reaching altitude again, Li Zhan selected a few actions that could comprehensively test the control system. When I was doing the barrel roll, an accident happened.

"Tower, I can't reverse the flight. I'm checking the flight control system. It's over." Li Zhan calmly reported the situation as usual.

Everyone in the tower was shocked. Wasn't it good luck? Why was there still a problem?

"Dongyao, repeat that!" Xue Xiangdong asked.

Li Zhan said, "The flight control failed. I'm flying upside down right now. I can't correct it. It's over."

SU-27SK No. 01 was flying with its legs in the air and its head downwards. Li Zhan suddenly got stuck in this posture while doing a barrel roll, and he immediately judged that there was a problem with the flight control system. He kept his height as high as possible while thinking rapidly about solutions.

Xue Xiangdong had no choice at all. Apart from the two instructors Nie Jianfeng and Tang Leilei, the only one with the most experience in using SU-27 fighters in the 101st Regiment was Li Zhan. In terms of familiarity with this fighter jet, Xue Xiangdong, who had just completed modification training, was in no way comparable to the above.

Soon, Li Zhan decisively made an accurate judgment and said, "Tower! I judge that there is a problem with the autopilot. Prepare to disconnect the autopilot, over!"

How to disconnect?

There is no disconnect switch.

Li Zhan's method was simple and crude. He found the hard connection and directly pulled out the line...

Maintenance: Is this okay?

It was successfully changed to manual control. The flight control system did not completely fail. The problem was only with the autopilot system. The reason why pilots think that third-generation aircraft are easier to drive than second-generation aircraft is because many functions have been automated and intelligent. For example, trimming needs to be done manually when flying the J-7. When flying a third-generation aircraft, sometimes it is as simple as pressing a button and the fighter will complete the trimming with the help of the autopilot.

Generally speaking, the chance of problems with the autopilot is very low, but for the No. 01 fighter jet that has been rewired and undergone major repairs, such problems are nothing to be surprised about.

Modern aircraft are precision machinery, and the entire system is very complex, but sometimes it is quite simple, so simple that simple methods can be used to troubleshoot. When designing each weapon, we will try our best to fully consider the actual use of the troops. The early prototype of the SU-27 had a mechanical transmission, but a telex was installed longitudinally due to a serious accident involving loss of attitude.

Li Zhan used strong methods to remove the autopilot control of the fighter plane and changed it to full manual control. After that, he slowly regained control of the fighter plane, leveled the fighter plane, and eliminated the danger.

"Tower, please continue the test flight and more fully check the repair situation. It's over." Li Zhan called the tower.

Xue Xiangdong asked, "Dongyao, how is the attitude of the aircraft? Is the flight control system normal? Over."

"It's relatively stable. There's no problem with the flight control, but I've disconnected the autopilot and now it's full manual control. It's over." Li Zhan said confidently.

"Dongyao, you can continue the test flight, it's over." Xue Xiangdong pondered slightly and agreed to Li Zhan's request.

It's best to be able to find all the hidden dangers in one test flight, and it's just the autopilot that fails, which is not a big problem. There are so many early second-generation aircraft that have autopilot. They still drive smoothly and smoothly.

If the entire flight control system failed, Xue Xiangdong would not hesitate to order Li Zhan to return to the field and land. If he lost control of the fighter plane, he would resolutely order Li Zhan to parachute and abandon the plane. An old aircraft that has been in service for more than ten years can only be used for one or two years at most. If it is gone, it will be gone. But pilots are rare, especially a super top ace like Li Zhan who can't fight hard. A combat pilot who is so handsome that people and gods are outraged.

Li Zhanyi was a brave man. He drove the hairless old aircraft No. 01 and spun, jumped, rolled, dived, climbed and looked at the sky. Except for the large overload maneuver, he did everything else at least twice, and he actually managed to fly a J-7B. type feeling. The double chrysanthemums of the No. 01 old machine sometimes bloom and sometimes lock as the thrust changes, like a girl sitting on a big pendulum, closing in waves.

It took Li Zhan a full two hours to land and the test flight was over. The repair shop and maintenance staff still had to find out the cause of the autopilot failure and conduct a comprehensive overhaul of the fighter jet.

When Li Zhan landed, a top-secret telegram was sent to Beikuchang Station from Guo Beimu, chief of staff of Dudachang Station, and Li Zhan was designated to read it and burn it after reading.
