Huge cumulonimbus clouds from the plateau mountains came over the city, and people experienced three consecutive days of rainy weather.
After coordination with the troops, Chengdu Luoma Factory requisitioned a maintenance hangar at the third-rate airport to repair the No. 01 Black Ribbon. Some important test flight data was exported immediately, and then began to analyze the cause of the failure, find out the cause and solve the problem.
.
Li Zhan also temporarily stayed at the third-rate airport to cooperate with the research and development personnel.
Considering confidentiality issues, the No. 01 Black Ribbon can neither be transported back to the factory by road nor can it be disassembled and transported back by transport aircraft, so it can only be flown back. Therefore, it must be repaired, or at least restored to normal flight capabilities.
The manufacturer sent a large number of personnel and equipment to the third-rate airport, and relevant military units also came. According to the technical team's estimation, it would not be possible to complete the work here in a few months. Just analyzing the cause of the failure is a major undertaking.
Engineering. After Li Zhan wrote the detailed test flight report, he did not rest, but followed the research and development staff to study. His assistance can be more targeted.
The fuselage structure of No. 01 Black Ribbon showed no deformation. This result surprised the developers. You must know that the nose of the aircraft suddenly dropped at supersonic speed, which was a very large overload maneuver.
Withstanding such a high overload, it means that the aircraft's fuselage strength test flight is no longer needed. No test flight data is more convincing than the current data.
What surprised the technical team the most was that the two engines that were originally expected to be seriously damaged were actually in normal condition. After a comprehensive and detailed inspection of the power system, it was found that the cause of the power system failure was a malfunction in the electronic systems that controlled the two engines.
problem, resulting in the engine losing feedback to the pilot's control.
The more important issue brought about by this is that there must be some kind of defect in the avionics system, at least the stability cannot meet the design requirements. The technical team is well aware of this. The fourth-generation aircraft is a technology designed by our country.
The most advanced and complex fighter aircraft itself has a gradual maturation process.
However, when such a serious failure occurred, the technical team was still reprimanded by their superiors, requiring them to immediately set up a research team to concentrate on solving the problem as soon as possible and completely eliminate hidden dangers in this area.
This is the value of a test pilot.
In other words, the planes flown by test pilots all have faults, and the faults can only be exposed through flying, not just flying out of the aircraft's flight envelope.
Understanding test pilots from this perspective will give you a clearer understanding of the difference between test pilots and pilots. If a carrier-based fighter pilot is a dancer on the tip of a knife, then a test pilot is a guardian of life wrestling with death.
.
Including carrier-based fighter jets, test pilots first fly them to confirm that they meet the design requirements and summarize a set of specifications before they are handed over to front-line pilots.
Therefore, in many cases, the technical and theoretical foundation of test pilots is no worse than that of professional technicians, and some powerful ones can even guide the R&D team to make improvements and publish theoretical books. All test pilots are excellent. For example, Chen Ming, although his combat flight skills
Maybe they can't compare to Li Zhan, but in terms of technical theory, ten Li Zhans combined can't compare to him.
The last arrangement for Li Zhan and Chen Ming to partner up was officially based on this consideration.
Li Zhan talked about his feelings and pointed out what the performance should be like when getting off the aircraft, what kind of performance should be achieved and what the actual performance was. These very specific opinions are difficult for the R&D team to understand. At this time, Chen Ming based on
Li Zhan's opinions are transformed into professional guidance and expressed in terms, which can be easily understood by the R&D team.
The two worked together as assistants for more than 20 days and ate excessive meals at a third-rate airport for more than 20 days. On the thirtieth day, the entire maintenance work was finally completed. They took advantage of the late night rest at the airport.
A series of ground tests were conducted during the period, including ground trials and rolling tests.
After another three days of ground testing, it was confirmed that the aircraft had restored its flight capabilities. On the fourth night of the night, Li Zhan piloted the No. 01 Black Ribbon from the third-rate airport and returned to Chengdu Loma Airport. At the same time, the ground team also took a deep breath late at night.
Withdraw all.
The next analysis work will be more and heavier, and at the same time a new round of improvements will be made to the No. 01 Black Ribbon. Then Li Zhan will start to take some time off.
Bao Guanhua came to him and said, "There is no holiday for the Spring Festival. May Day is coming soon. Now that there is not much to do, you can take a holiday and I will grant you a thirty-day holiday."
Li Zhan smiled and said, "Old leader, you are no longer the leader of the army. How can you approve my leave?"
"Even if I change my career, I will still be your leader." Bao Guanhua smiled and pointed at Li Zhan and motioned for him to sit down, "Wan Jun is pregnant with the child for six months, shouldn't you, a father, go back to see her?
"
Li Zhan suddenly became a little worried and said, "Yes, I am very worried, but also a little scared."
"It's human nature." Bao Guanhua said with a smile, "It's always like this when you're a first-time father. My situation was worse than yours back then. I couldn't sleep all night long."
"Really? I thought it was me who had the problem." Li Zhan said in surprise.
Bao Guanhua said with a smile, "Having a child means taking on the responsibility of a family. When the child comes out, you have to raise him. Thinking about how your parents have brought you up, you have doubts about your abilities. This is normal.
of."
"The bottom line is that I'm not mentally prepared to be a father yet. You don't have to worry too much. As the old saying goes, it will take care of itself when it reaches the bridge. By that stage, you will understand everything."
Li Zhan nodded slightly, "I hope so."
"Then why are you hesitating? Let me tell you, women especially want their husbands to be by their side at this time, and no one can replace this." Bao Guanhua said.
Li Zhan said, "I understand, I will go back tomorrow."
Nodding, Bao Guanhua talked about work matters. He said, "This time the improvements are relatively large. According to the current situation, the technical index level of the fourth-generation aircraft finally delivered to the troops will be several times higher than the original design."
percentage points."
He lit a cigarette and took two puffs, and said, "This also means that the standards for future test flights will be higher. It is very likely that many projects did not exist before. You can think about how to carry out subsequent test flights."
"Old leader, there are some things I don't like to say." Li Zhan frowned and said in a deep voice.
Bao Guanhua said, "Speak, speak boldly."
Li Zhan is no longer the young man who only knew how to pull rods a few years ago. After more than three years of service experience, he has matured in all aspects. What he said so carefully is obviously something that is not convenient to say on other occasions.
After sorting out his thoughts, Li Zhan said, "I think it is not in line with actual requirements to design the F-22A as a pursuit target."
This sentence was completely unexpected. Bao Guanhua had never doubted this goal, and the R&D team had never wavered in this belief.
Before the first flight of the Black Ribbon, the F-22A was the only true fourth-generation aircraft in the world, whether it was in active service or under development. There is no problem at all with the F-22A as the target of pursuit, and it is indeed the case.
It has been done, and many technologies are even more advanced than the F-22A.
There is no problem in aiming to catch up with the F-22A!
