Factory 132 has made money and has to invest in the research and development of new projects in Factory 132! We must continue to improve the J-7, so that we can survive.

Moreover, the 132 factory belongs to the Air Force, and the 611 factory belongs to the third aircraft department, and the top bosses of the two departments are different, besides, that project is destined to have no future, why would the 132 factory fund such a project?

So, Qin Feng ate silently and didn't speak, he remembered that everyone was selling vegetables at the factory gate, and playing hide and seek with those red armbands, in fact, there was also sadness in it.

As a designer, who wouldn't want to design a new model of warplane? Smash the pot and sell iron, too! This is the pride of the 611 Institute.

However, the country is in transition, and if the country wants to develop its economy, the investment in scientific research will definitely decline, and in this case, the funding that 611 can get will be less and less.

Suddenly, he had another idea: "If all the mapping and copying work of the MiG-21MF is given to the 611 Institute, in this way, the 611 Institute will have sufficient funds, and our factory will be able to free up its hands to modify our J-7 II, isn't it the best of both worlds?" ”

"You, don't think nonsense, if you let Tu Lao know this, I'm afraid I'm going to have to my beard."

Tu Lao and Song Lao, they are arguing over this surveying and mapping imitation, one must be directly surveyed and mapped, and the other must be thoroughly explored, in this case, how can it be possible to carry forward the style and let the project out?

Besides, from the perspective of Factory 132, I won't let it go.

In this way, it will make the country glow with greater vitality, and there will be competition, and only then can it be improved.

"The stall tailspin has always been a forbidden area for our domestic fighters, which seriously troubles the improvement of the training level of the Air Force aviation and the performance of the aircraft, and affects flight safety. Once the aircraft stalls and enters the tailspin state, it often leads to the destruction of the aircraft and the death of people. According to statistics, in the history of world aviation, 41% of the causes of combat aircraft crashes are caused by tailspin. It is also because of this that we have to conduct research and test flights of stall tailspin. ”

This time, Qin Feng did not continue to stay in the 132 factory, and the test flight institute was quite cautious about the tail spin test flight of the J-7 II fighter, and deliberately left the last subject before the fighter was finalized to the test flight institute.

So, Qin Feng stayed in Factory 132 for about a week, repeatedly studied domestic and foreign materials, and then he piloted the J-7 II fighter and flew to the test flight institute.

China Flight Test Research Institute, referred to as the Flight Test Institute, is located in Yanliang District, Xi'an City, founded in 1959.

It is the only state-level authorized national certification and flight test institution for military and civil aircraft, aero engines, airborne equipment and other aviation products, a state-level flight test technology research institution, and a national "aircraft airworthiness accreditation laboratory".

It can be said that most of the planes started their test flights from here.

Since 1951, the state has transferred the five repair shops of the Air Force to the Aviation Administration, and China's aviation industry has begun to take the road from imitation to independent development of aircraft. The predecessor of the Test Flight Research Institute, the China Flight Research Institute, came into being at that time.

After a variety of investigations, it was finally decided to build on the original site of the 11th Aviation School in Yanliang, Guanzhong, Shaanxi. The conditions here are good, there are many flying days a year, the weather is stable, there are no disasters such as huge sandstorms, and the absolute altitude is low.

The first kind of test flight of the whole aircraft carried out by the Flight Research Institute was the "Red Specialty" 502, that is, the Chujiao-6, after repeated research, the four major faults of the "Red Specialty" 502 were finally solved, and it was officially finalized on January 5, 1962. Nearly 50 years later, the Chujiao-6 is still the main beginner training aircraft of the Air Force's junior aviation schools, and it is still exported in large quantities.

Now, new domestic aircraft are still being tested here, such as the J-8 fighter of the 601 Institute, which is simply a frequent visitor to the test flight institute, and has been here for more than ten years.

The J-7 fighter used to fly here in the past, but the J-7 II transformed by Factory 132 was very sure, so these projects were done by Factory 132 itself, and they did not come to the test flight institute.

However, this last subject, the test flight of stall tailspin, after careful consideration by the superiors, was still chosen in the test flight institute.

At present, the entire tailspin test flight team is presided over by Li Tuan of the experienced test flight group in the test flight institute, and the atmosphere in the entire conference room is a little tense.

"Especially, the last time I received Egyptian friends, Comrade Qin Feng successfully changed from the tail spin in various places, which gave everyone a lot of encouragement, we must be determined to overcome the tail spin subject, we need to have a brave spirit and scientific operation, now, let Comrade Qin Feng tell you about it."

Qin Feng is a test pilot, but he has not been to the test flight institute much, he can be said to have been transferred directly from the air force to the 132 factory, and now, when he came to the test flight institute, he knew that the people present were the most familiar with the test flight old-timers, and his words were also very sincere.

"We know that tail spin is the most dangerous subject in flight, so in order to overcome the problem of tail spin, I have studied a lot of information from my peers." Qin Feng said: "After my summary, the tail spin includes two kinds of forward flying tail spin and inverted flying tail spin, and in each kind of tail spin, it is divided into fallen leaves, over-stall rotation, flat tail spin, steep tail spin, etc., each state is very complex. We should start the test flight step by step, and try to change the way we do it. ”

It is difficult to enter from Jane, this is the basic principle of test flight, Qin Feng said this, and everyone nodded.

"After summing up, I have also found various ways to enter the tailspin, and now, I will report to you in turn."

Qin Feng held a stack of thick notes in his hand, all of which he had summarized in the past few days, and when he saw Qin Feng start to read his notes, everyone was stunned, and then followed to understand it carefully.

Commander Li was also extremely excited, everyone thought that this would be a difficult challenge subject, who would have thought that an unknown test pilot of the 132 factory would actually summarize this subject!

With the entry of various situations, the analysis of aerodynamics, and even the flight experts present nodding their heads again and again, the confidence of the tail spin of this test flight is even greater.

"Comrade Qin Feng, your summary is so wonderful." By the time Qin Feng said the last page, two hours had passed, and everyone felt that they had gained a lot.

"It's all my own imagination." Qin Feng touched his head and said, for these materials, he doesn't know how many domestic and foreign documents he has turned over.

"Comrade Qin Feng, is there anything else to add?" Next to Captain Li, a leader of the test flight institute said.

Qin Feng thought for a while: "When I was looking for information, I found that foreign countries had begun to develop anti-tail rotating umbrellas. ”
