Super military empire

Aircraft assembly work is not as simple as other equipment assembly work.

Liu Yijiu didn't ask too much about the imitation of f14.

What he pays more attention to is the double-three project designed by China itself!

Once, Long Yaohua also asked Liu Yijiu that a fighter with three times the speed of sound and a ceiling of 30,000 meters is not too practical and more technically difficult. More importantly, the body of an excellent pilot cannot be used like this. Stay in flight for too long.

The speed of Mach 3 exceeds one kilometer in one second, and it is difficult for the body of an overloaded person in this state to bear for a long time.Otherwise, a good pilot will be scrapped.

Originally requested by the military high-level, or the initial goal of the project was only Double 26, which is a flying altitude of 26000 meters and a flying speed of Mach 2.6. It was itself in charge of Shen Fei 601. In the end, 611 was established and transferred to 611. .

It is precisely because the performance indicators are too high and the practicability is not too great. The main combat targets are the Soviet "Backfire" and the American b-1b supersonic bomber, which has little effect on other fighters and heavy fighters.

Liu Yijiu didn't say anything at the time, but he had a reason for having to get the double-three performance aircraft-flying in extreme environments, which required very high pilots.

In this way, it is necessary to improve the pilot's responsiveness and at the same time, improve the pilot's physical fitness.This requires more in-depth research on the human body, which leads to genetic engineering and some research on the development of human potential.

This aspect of the project in the Ninth Academy has always been carried out in secret, and even the top people who know about it are not many.Liu Yijiu wants to conduct research in this respect openly.

At the same time, such fighters have a very powerful role in intercepting strategic bombers coming from afar from the United States.When it is made into a heavy fighter, its carrying capacity is higher and its combat effectiveness is stronger.

The Republic does not need to be equipped with too many, dozens or hundreds are enough.

Moreover, as long as the Double Triple Project is successful, there will be more extended results!

There is no reason why Liu Yijiu doesn't pay attention.

The one in front of me is only assembled with the keel of the key bearing parts, the others have not yet begun to be assembled.

The same two turbofan eight engines, avionics systems, etc. have not yet been shipped to the assembly workshop because the metal parts have not been assembled yet.

"Is the turbofan eight's thrust enough?" Liu Yijiu frowned and asked, knowing that the double triple index is not easy to achieve.

Feng Lun, the chief designer in charge of the Double Triple Project, nodded hurriedly, and said to Liu Yijiu, “The turbofan eight designed by Mr. Qi and the others has a three-stage fan and nine-stage rectifier, so a single thrust has reached 138 thousand. Niu, the thrust-to-weight ratio has reached 8..."

For engine technology, Liu Yijiu put forward a lot of technical indicators, and in many cases he also put forward some key things, and he even pointed out many projects.

It's just that he hasn't tracked the test process recently, but he didn't expect the turbofan team of the 611 Institute to achieve such great results in this regard.

Hearing Feng Lun’s words, Huang Qiaosong couldn’t help but laughed, “Old Huang, the technical indicators of this turbofan eight were proposed by Director Liu, and many key designs were modified by Director Liu...”

Regarding Huang Qiaosong's flattery, Liu Yijiu just shook his head without explaining anything.

Heart disease in the aviation industry of the Republic has always been criticized, restricting the development of the entire aviation industry.

But under the current circumstances, the technology of such engines is not too stable.From the turbofan six to such a technical level, even if it is barely achieved, it can only be used reluctantly. The turbofan ten of that year has been in operation for several decades, and I don't know how many planes finally matured after falling.

"This is very demanding for the manufacturing industry. We can't just one-sidedly pursue performance indicators, safety, and stability, which are what we need. It is not that one or two engines have achieved results, which means that we have already done this. It was a success." Liu Yijiu understood what these people thought.

No special emotions appeared during the development of the turbofan eight, which made him somewhat incredible.

There have been countless special situations in the research and development of Turbofan X, which allowed the experts of the Republic to find solutions to problems and make continuous improvements.

In the process of scientific and technological research and development, you are not afraid of problems, you are afraid that problems will not occur.

Therefore, Liu Yijiu asked this question.

He always feels that this engine is too easy to make, even if the design of the overall turbine disc is adopted, the experience in this area is not enough to support it.

Both the Soviet Union and the United States have developed from one generation to another.Unlike China, it has developed directly across several generations without any problems, but it will make people feel a little unreliable.

"There weren't any major problems in the turbofan eight experiment, right?" Liu Yijiu asked everyone.

Qi Hai, who is in charge of the design, is not here, and no one else can answer.

"This is the first self-designed advanced fighter in our country. The process can be slower and safety must be ensured!" Liu Yijiu particularly emphasized the issue of safe production.

At the same time, quality accidents must be taken seriously.

"Director Liu, there should be no problems with these engines. Mr. Qi said that in the design process, not only our turbofan six, but also the r-15 engine of the MiG-25 and the tf30-p-412 of the f14 were used. Afterburner turbofan engine..."

"Don't tell me what I should, maybe it's an uncertain question! This is an issue that concerns the future of our entire project, pilot safety, and even national defense security!" Liu Yijiu was very angry when he heard this.

In technology research and development, such uncertain vocabulary must never appear.

Feng Lun who said this was a little speechless.

For this matter, Liu Yijiu can only ask Qi Hai, the chief designer of the engine.

"Where is Qi Hai now?" Liu Yijiu asked Qi Hai's location.

The engine is the first technical problem to be overcome by domestic fighters.

Before that, you still have to listen to Qi Hai's views, otherwise even if the first flight is successful, it will be a big problem to develop quickly.

Apart from other things, fighters like the F-20 and F-31 of the Republic have made rapid progress after their first flight, but in the end the speed of equipping troops was greatly slowed by engine problems.At that time, the domestically produced turbofan 18 and turbofan 20 had many problems, and they could only be equipped with engines imported from Lao Maozi.

Although Lao Maozi was left to death by the American emperor, he did not openly supply engines to China in this regard, and do not count on technology or anything.

Between countries, there are only interests, not eternal friendship.

When needed, they naturally become allies.

In the end, Lao Maozi almost completely fell to the West, otherwise, the pressure on the Republic would not be that great.

Electronic systems and radar systems can be a bit close. Engines are the heart of the entire fighter, and the soul of the entire fighter!

"At Phoenix Mountain Airport, during this time our Turbofan 8 is undergoing aerial platform tests..." Liu Yijiu kept asking various questions, which made Huang Qiaosong and others overwhelmed.

When Liu Yijiu heard this, he looked at the fake f14 that had been assembled in the opposite corner, frowning even more tightly.

However, he didn't say anything, but waited for the explanation from the group of people in front of him.

"Director Liu, this is the case. Due to tight time and heavy tasks, the turbofan eight test has not been completed. In order to ensure the smooth first flight, we did not use the turbofan eight, but the f14 that we disassembled. The engine of..." Under Liu Yijiu's pressure, even the kind people had to tell the truth.

Whether the turbofan eight can make the imitation f14 fly for the first time, in the test flight after the first flight, the maneuverability and other aspects of the imitation fighter have to be tested. In order to ensure the smooth progress of the project, Liu Yijiu also There is very little time here, and the other members of the Ninth House Management Committee have never seen it.

After discussion, Huang Qiaosong and others took this approach in order to make the first flight.

After the explanation, everyone looked at Liu Yijiu cautiously. The imaginary anger did not come. Liu Yijiu just sighed helplessly, and then said to everyone, "I will eat in the cafeteria at noon. Let’s have a meal, and then we will go to Phoenix Mountain Airport to see the situation..."

The group naturally had nothing to say, and it was just noon now.

A casual lunch was settled in the cadre canteen of 132. The group took several cars and headed towards Phoenix Mountain Airport, the largest military airport in Chengdu Air Force Base.

Phoenix Mountain Airport, which is the largest military airport in the entire southwest, was built in 1931 and expanded into a military airport in 1937. Then the Republic was established and has been expanding. It is an important airport for the air force of the Rongcheng Military Region.

In the vicinity of such an airport, there are not many residents, and the new fighter planes are tested here, and it is not easy to leak secrets.

The same is true for Taipingsi Airport, but there are a large number of residents around Taipingsi Airport, and the development of Chengdu in the future, the development of the south and west will expand rapidly, Liu Yijiu even thought about not building there, and finally the production line of Yunshi And the research base is placed at Taiping Temple Airport.Because it is a civilian aircraft, there is no need to worry about leaks in appearance.

As for the final development of Chengdu, how can such a huge aircraft factory change the direction of a city's expansion?

The security of the Phoenix Mountain Military Airport is not much weaker than the current Taiping Temple, because this is the Rongcheng Air Force Base. Although it is only equipped with the old planes such as the J-7, H-6, and Qiang-5, it is also the home of the entire Rongcheng Air Force.

After Qi Hai heard that Liu Yijiu had come here, he waited at the airport's entrance early.
