At present, the China Flight Test Research Institute in Yanliang District, Xi'an City, which is referred to as the flight test institute, has not yet been used on a large scale, although some test flights have also been carried out, but there is not much content for test flights.

Generally speaking, new models are developed, and in the later stage, they choose to enter the test flight institute for professional intensive test flights, like the original J-7 has just been manufactured, and it is flown to the test flight institute for test flights.

However, the J-7II is not needed, this aircraft is only a simple and improved model of the J-7, after being manufactured in the 132 factory in Chengdu, it will be directly tested in the factory, and after flying various subjects, it can be finalized and equipped.

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

The test flight team has always lived in the guest house of Factory 132, and everyone rarely comes to the 611 Institute, after all, the flight task is very heavy, Qin Feng went to know that the 611 Institute is also a key military aircraft research institute in China, and he has long wanted to come and see it.

The big brother of domestic military aircraft development, that is the Shenyang Aircraft Research Institute, code name 601, almost all domestic military aircraft are built from the 601 Institute.

However, the country also felt the risk in advance, after all, the 601 Institute was too close to the north, and after the war with the Soviet Union, it had to take into account the danger of war.

At this time, some experts from the 601 Institute traveled thousands of miles to Chengdu to form the new Chengdu Aircraft Research Institute, No. 611.

The Sichuan Basin, the land of abundance, was moaning everywhere under the iron hooves of the Japanese invaders, but it was still not defiled by the Japanese invaders.

In the event of a terrible war, this is the safest rear.

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

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

A dilapidated wooden table, like one of the big ones brought from the cafeteria, was on top of which an old man was working at his desk.

His hair was already a little gray; His body was prostrate on the table, his right hand still struggling to figure out something.

After a few minutes, he finally looked up, wiped his glasses, and then looked to the side again.

In the corner of his desk, there was a model of a fighter plane, this silver-white painted fighter plane, which was different from all previous fighters.

It has no tail, and the entire fuselage, from the middle to the rear, extends from a huge delta wing, 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.

That's the canard layout.

The nose is coated in a bright red color, and on both sides of the nose are rectangular air intakes that open sideways.

Looking at this model, the old man's eyes showed anticipation, 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 he saw a person wearing a light blue flight suit outside the crack in the door, and suddenly, he shouted: "Comrade Qin Feng?" ”

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

That's right, this old man is Song Lao, the deputy chief designer of the 611 Institute.

Song Lao was born in Kunming on March 26, 1930. Since 1950, he has served as an aircraft mechanic and squadron mechanic in the Air Force. In August 1954, he entered the Air Force Engineering Department of the Military Engineering College of the People's Liberation Army for further study in aircraft engines. In July 1960, he graduated from Kazakhstan Military Industry and was assigned to Shenyang 601 Institute as a designer and pneumatic team leader.

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

In 1964, the Central Military Commission issued the task of developing a new aircraft, and in order to intercept Soviet bombers, it put forward the "double two" target of Mach 2.2 and a ceiling of 20,000 meters.

At this time, Song Lao led the group to put forward a report on "Preliminary Analysis of the Use of 2 815 Engines for the Modification of MiG-21 Aircraft", which was recognized by everyone.

Because of the tight time, Song Lao appeared at the venue with a wooden model that was made overnight, and he didn't even have time to paint it. It is jokingly called "roast duck".

Song Lao talked about the development and current situation of the US-Soviet fighters, talked about the design principles and concepts that China's new aircraft should follow, and finally introduced his own twin-engine design plan.

The originally chaotic venue quieted down, and the leaders and experts attending the meeting quickly unified their understanding, and the J-8 fighter quickly set up the project.

For Song Lao, the J-8 is just a temporary alternative, and what has been lingering in his mind is the plot of the duck layout.

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

As a result, the J-9, which is synchronized with the J-8, was also established, which is the model around Song Lao.

Because the Shenfei 601 Institute was responsible for the development of the J-8, he could no longer spare his energy, so Song Lao 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 Song Lao's J-9 still only exists on paper. After all, the country's funds are limited, and only the main funds can be used to carry out the J-8 project, and this J-9 can only stay in the design stage.

Not to mention the constant revision of the indicators by the Air Force, which is definitely beyond the country's industrial base, and the turbofan-6 that cannot be finalized at all.

"I've heard about today's daytime, Qin Feng, in order to keep today's J-7 fighter, you took a big risk." Old Song watched Qin Feng walk in and said to him, "Your deeds, let us be proud of you." ”

Qin Feng shook his head: "Every test pilot will do this." Old Song, are you so late, are you still busy? ”

After speaking, the corner of Qin Feng's eyes caught a glimpse of the model of the J-9, this plane, which looked very curious.

Song Lao looked at Qin Feng's appearance and knew what he was thinking.

J-9, once a key project of the state, but now ...

According to the confidentiality requirements, the J-9 cannot be said to Qin Feng in front of him, but he recently submitted a report to his superiors that in the development of the new aircraft, it is necessary to let the test pilots join in at an early stage to conduct joint research, so Qin Feng, an outstanding test pilot, is also fully qualified to understand.

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

"Song Lao, *** taught us that all imperialism is a paper tiger, and although our equipment is backward, our pilots can rely on the spirit of not being afraid of hardship and death to fly our J-7 and intercept any invading enemy." Qin Feng said.

"Really?" Song Lao looked at Qin Feng, as if he could see Qin Feng's heart at once.
