Now, the China Flight Testing Research Institute, which is located in Yanliang District, Xi'an City, is a facility called the Flight Testing Institute, has not been used on a large scale. Although some test flights are also carried out, there is not much content for the test flight.

Generally speaking, new models were developed. In the later stage, they chose to enter the test flight institute for professional and intensive test flights. For example, after the J-7 was manufactured, they flew to the test flights for test flights.

However, the J-7 II is no longer needed. This aircraft is just a simple improved model of the J-7. After it was manufactured in Factory 132 in Chengdu, it was directly tested in the factory. After flying various subjects, it can be finalized and equipped.

Such a test flight also requires some test pilots, so Qin Feng and a few companions formed a test flight team together, and Wang Gang was their team leader to carry out the J-7 test flight work together.

The test flight team has always lived in the guesthouse of Factory 132. Everyone rarely comes to 611. After all, the flight mission is very heavy. Qin Feng went to know that 611 is also a key military aircraft research institute in China, so he had long wanted to come and have a look.

The big brother in the development of domestic military aircraft is the Chenyang Aircraft Research Institute, code-named 601. Almost all domestic military aircraft were built from Institute 601.

However, the country also had a premonition of the risks in advance. After all, the 601 Institute was too close to the north. After fighting with the Soviet Union, it had to consider the danger of war.

At this time, some experts from the Institute 601 went thousands of miles to Chengdu to form a new Chengdu Aircraft Research Institute, number 611.

The Sichuan Basin, the country of Tianfu, was groaning everywhere under the iron hooves of the Japanese invaders, but the place was still not defiled by the Japanese invaders.

Once a terrible war breaks out, this is the safest rear.

Now, it was already dark, Qin Feng walked into the small building and stopped in front of a door sign with the director hanging on it along the mottled door sign.

The door is a false door, and you can clearly see the inside of the room from here.

A shabby wooden table was like a big dining table that was moved from the cafeteria. On the wooden table, an old man was working at his desk.

His hair was already a little white; his body was crawling on the table, and his right hand was still trying hard to calculate something.

A few minutes later, he finally raised his head, wiped his glasses, and then looked aside again.

Just in a corner of his table, there was a model of a fighter plane. This silver-white painted fighter plane is different from all previous fighters.

It has no tail wings, and the entire fuselage extends from the middle to the rear, which are huge triangular wings, and in front of this wide main wing, there are a pair of small canards.

It looks like a duck standing up and waving its wings.

This is the duck-style layout.

The machine head is coated with bright red, and the sides of the machine head are rectangular air intake channels that open sideways.

Looking at this model, the old man's eyes showed hope. For him, this is his child. He has been working for this project for ten years.

Originally, he wanted to bow his head again, but saw a man wearing a light blue flight suit outside the crack in the door. He immediately shouted: "Are you Comrade Qin Feng?"

So Qin Feng pushed open the door and walked in: "Yes, Mr. Song, it's so late, are you still busy?"

That’s right, this old man is Mr. Song, deputy chief designer of Institute 611.

Mr. Song was born in Kunming City on March 26, 1930. He served as an aircraft mechanic in the Air Force since 1950 and a squadron mechanic. In August 1954, he joined the Air Force Engineering Department of the People's Liberation Army Military Engineering College to further study. He graduated from Harbin Military Industry in July 1960 and was assigned to the Institute of Chenyang 601 as a designer and a pneumatic team leader.

From that time on, Mr. Song began to take the lead, and soon, Mr. Song stood out.

In 1964, the Central Military Commission issued a task to develop new aircraft. In order to intercept Soviet bombers, it proposed a "double two" indicator of Mach 2.2 and 20,000 meters ceiling. The participants were worried. Relying on China's weak scientific research capabilities, even the J-7 had not yet fully understood it. How could it be possible to create a fighter jet that meets the needs of the central government?

At this time, Mr. Song led the team to propose the report "Preliminary Analysis of the MiG21 Aircraft Modification Using Two 815 Engines", which won everyone's approval.

Because of the tight time, Mr. Song appeared in the venue with a wooden model overnight, and there was no time to paint. He was laughed at as "roasted duck".

Mr. Song started with the development and current situation of US-Soviet fighter jets, talked about the design principles and concepts that Chinese new aircraft should follow, and finally introduced his dual-engine design plan.

The originally messy venue became quiet, and the leaders and experts present quickly unified their understanding, and the J-8 fighter jets quickly launched a project.

For Mr. Song, the J-8 is just a temporary alternative, and what he can't get away with is the plot of duck-style layout.

If you want to develop an advanced third-generation aircraft, you must have advanced aerodynamic layout, and the duck-style layout has inherent advantages.

Therefore, the J-9, which is synchronized with the J-8, was also launched, which is the model around Mr. Song.

Because the Chenfei 601 Institute was responsible for the development of the J-8 and could no longer spend any energy, Mr. Song was transferred to the Chengdu 611 Institute in April 1970 to continue the J-9 project until now.

In a blink of an eye, nearly ten years have passed, and Mr. Song’s J-9 still exists only on paper. After all, the country’s funds are limited and can only withdraw main funds to carry out the J-8 project. This J-9 can only stay in the design stage.

Not to mention that the Air Force's continuous modification of indicators is definitely beyond the country's industrial foundation, and the turbofan-6, which is always indefinite.

"I have heard about what happened during the day today. Qin Feng, in order to protect today's J-7 fighter jet, you took a lot of risks." Old Song looked at Qin Feng walking in and said to him: "Your deeds make us proud of you."

Qin Feng shook his head: "Every test pilot will do this. Mr. Song, are you still busy at such a late age?"

After saying that, Qin Feng saw the model of the J-9 from the corner of his eyes. This aircraft looked very curious.

When Mr. Song looked at Qin Feng's appearance, he knew what he was thinking.

The J-9 was once a key project of the country, but now...

According to the confidentiality requirements, the J-9 cannot tell Qin Feng in front of him, but he recently submitted a report to his superiors. In the development of the new aircraft, the test pilot needs to join in and conduct research together. Therefore, an outstanding test pilot like Qin Feng is fully qualified to understand.

"Qin Feng, do you think our J-7 can support the sky of the motherland?" asked Mr. Song.

"Old Song, *** taught us that all imperialism is a paper tiger. Although our equipment is backward, our pilots can drive our J-7 and intercept any invading enemy with the spirit of not being afraid of hardship or death." Qin Feng said.
