Lei Qiang drove the Super-7 and flew forward. Before entering the second turn, he finally couldn't help but press the operating lever skillfully and made a rolling move.

The sky and earth line suddenly began to rotate. The Super-7 was like a spoiled child. He turned around in the sky and turned around. Lei Qiang flattened it again. The rolling speed of the previous roll was indeed much faster than that of the J-7!

The people on the ground were sweating. Tu Jida looked at the fighter plane in the sky, as if he was looking at his baby in his cradle. He saw that the landing gear was not retracted while the plane was rolling, as if it was a child kicking his legs. However, this action was not what he had planned, and this Lei Qiang!

After turning three times in the Super-7, it was facing the runway and landed slowly.

The speed reduction parachute in the rear rear cabin opened and the plane stopped.

All the designers immediately surrounded him and looked at Lei Qiang walking down from the cockpit.

"How do you feel?" Tu Jida asked.

"Old Tu, our fighter is simply too flexible! The close combat capability must be very good. When it is equipped with advanced fire control, it must be the most advanced fighter in our country!"

Hearing this, everyone present cheered. As a fighter jet developer, it is such a proud thing to be able to design a new type of fighter jet!

They were lucky because this project, which was almost entirely independently developed, received the consent of superiors and the injection of foreign funds. Otherwise, they would not have the ability to continue the development plan.

Tu Jida looked at the fighter jet on the runway, felt the cheers of the people around him, and was full of gratitude to the person in the Middle East. According to the other party, the technical level of the J-7 has to be improved by a higher level! After the Turbojet 13 engine is developed and installed on the aircraft, the performance will be greatly improved.

And in the other two places in China, we are not so lucky.

Shenyang in the north is now full of heavy snow and cold weather.

However, the atmosphere in the Shenyang Aero Engine Research Institute, located in the suburbs of Shenyang, is very depressing because the turbofan 6 they developed over more than ten years is about to become a project that has been cut off because they have no installed targets.

The turbofan 6 is a military afterburner twin-rotor turbofan engine with a thrust-to-weight ratio of 6, which embodies the lifelong efforts of many people in the Shenyang Aero Engine Research Institute. In September 1965, the plan demonstration work was completed, technical design was started, and trial production was put into operation in May 1966. In June 1968, the first test machine began to run the bench and tested, and was affected by the cultural and cultural heritage in the middle. Until October 1980, the performance reached the design index. In October 1982, the 24-hour pre-flight test was passed, and the whole machine was tested for 334 hours.

This engine has high thrust, good subsonic cruise economy, fast start and accelerate. The rotor adopts a 5-full support scheme, compact structure, reasonable layout, and uses a large amount of titanium alloy materials. Therefore, the engine has a light weight, a large thrust-to-weight ratio, and its overall performance is no less than that of contemporary aircraft engines such as mk-202 and m53.

During the development, various problems such as starting difficulties, compressor surge, high turbine inlet temperature and large vibration were overcome. After many modifications, testing and repeated debugging on the entire machine, a lot of work was done, and each component and overall performance had reached the design index.

This is an upcoming baby, but it faces the same problem because of the dismount of the Qiang-6 and the J-9. The country's economy has mainly shifted to construction, and no more funds have been invested in such unimpressive projects.

In Shanghai in the East, people with the same fate as theirs are still working hard.

Ma Fengshan, director of the Shanghai Aircraft Research Institute and chief designer of Yunshen, is still struggling to make the future of Yunshen.

As early as 1968, after the H-6 test flight was successful, Premier Zhou proposed: "Can you design a jet passenger plane based on the H-6?" Marshal Chen Yi also said: "As the Minister of Foreign Affairs, I cannot take my own plane abroad, and my status is different from other countries!"

On August 21, 1970, the State Planning Commission and the Military Commission's National Defense Industry Leading Group issued a task to Shanghai for the development of large passenger aircraft and its engines, code-named "708 Project". According to **'s proposal, the development and coordination assembly base of the 708 was placed in Shanghai. In September 1970, the first batch of support personnel of the Ministry of Machinery arrived in Shanghai, and Xiong Yan and Ma Fengshan were the heads of the design team to develop this largest transport aircraft in China, realizing the leapfrog development of China's transport aircraft from ten to hundreds of tons to hundreds of tons.

The maximum take-off weight of Y-10 is 110 tons, the maximum cruising speed is 974 kilometers per hour, the practical ceiling is 12,000 meters, and the maximum range is 8,300 kilometers. It is the same magnitude as the Boeing 707. During the development, nearly 100 new materials, more than 100 new standards and new processes have been used, and valuable experience in the development organization work. The domesticization rate of the fuselage is 100%. In addition to the engine being developed and has to be purchased from abroad because the supporting turbofan 8 is still being developed, the domesticization rate of avionics and mechanical systems exceeds 96%. Now Y-10 has trial-produced two aircraft, one for static strength tests, which fully meets the design requirements. The other aircraft has flew to many cities across the country after its first test flight in September 1980 and has flew to Lhasa several times.

But now, the fate of Yun-Ten has begun to change greatly, because at the top, Ma Fengshan is passing the resolution to produce the US McDonnell 82 aircraft, and Ma Fengshan is very sad about this, but he is still persevering.

However, since the beginning of the year, the research and development funds of Yunshen have been in a state of silence. The country is unwilling to invest in this, but would rather believe the Americans' nonsense. Even if Ma Fengshan does not serve as the chief designer of Yunshen, he is very disgusted with these comprador behaviors of the upper class because he knows that core technology can never be bought! Ma Fengshan actively applies to his superiors, hoping to obtain funding support. Yunshen will succeed soon and must not let it go!

At the same time, Ma Fengshan has learned that in Chengfei, they have made large-scale improvements to the J-7 due to their overseas investment. Since the country is unwilling to allocate funds to the Y-10, then if there is funds from the Middle East to make this project come alive, he is willing to give it a try!

Even the superiors of the military aircraft have agreed to allow overseas investment. Ma Fengshan is very confident that the superiors will agree to this Yun-Ten passenger plane that has lost interest in the senior management. However, I don’t know if the Middle East is willing to invest?

He sent a group to Iraq, hoping to get support, and the team leader was Cheng Yun.
