A big country of aerospace with black technology

After the successful first flight of the J-10, several long-term test flights began immediately, almost continuously testing various flight data of the J-10 fighter.

Especially the data under each limit state, such as limit elevation, limit flight speed, maximum range, maximum take-off weight, etc.

After testing, the J-10 fighter has a limit elevation of 18,000 meters, a maximum speed of Mach 2.5, a maximum take-off weight of 20,868 kilograms, a bomb load of 8,500 kilograms, and a maximum range of 3,000 kilometers.

Because it uses a turbofan ten engine that is more compatible with the J-10 fighter.

Compared with the previous life, the performance of the J-10 fighter in this life has been improved by a small amount.

In addition to the efforts of Zhang Xingyang, there are also countless scientific research institutes, universities, and factories under the J-10 project.

"Dean Zhang, it's hard work for you to make another trip."

As the chief engineer of the J-10 project, Song Tianxing warmly shook the hand of Zhang Xingyang who came from afar.

It has been more than a month since the first flight of the J-10.

Song Tianxing has been in a good mood during this period of time because of the successful first flight of the J-Shi, and his whole body is much rounder visible to the naked eye.

"Master Song, the food is good during this time."

Both parties were in a good mood, and Zhang Xingyang even made a small joke.

"Hahaha, isn't this the successful first flight of the J-Shi, the mood is better, and the appetite is better!"

"Mr. Song, how is the flight status of J-10 at present? Is there any problem with the engine?"

Compared with Song Tianxing's weight and health problems, Zhang Xingyang is more concerned about the situation of the turbofan ten engine.

After all, there is still a lot of my own hard work here, as if it is my own child, I have to care about it.

"The condition of the engine is much better than we expected, even better than the AL-31F engine we wanted to use before!"

When mentioning the turbofan-10 engine, Song Tianxing introduced the performance of the turbofan-10 on the J-10 fighter very excitedly, just like a child mentioning his favorite toy.

"We even tested it with an AL-31F that was taken from an Air Force Su-27 with a turbofan ten engine."

"It was found that the thrust of turbofan 10 is greater than that of AL-31F, and under the same standard thrust, the fuel consumption is also lower."

"In this way, our aircraft can fly farther and higher!"

Song Tianxing's praise of the turbofan ten engine made Zhang Xingyang feel extremely happy.

It's like parents are sincerely happy when they see others praise their children!

"Although our research institute has made some efforts in the research and development process, the main research and development work is still done by Chief Teacher Zhang Zhengjiang and his research team."

Zhang Xingyang is very self-aware, he doesn't think that the other party's compliments are all for himself, actually there are many people who should accept these compliments.

"Master Song, how long do you think it will take for our J-10 to be mass-produced and equipped with troops?"

Asked this crucial question, the smile on Song Tianxing's face gradually froze and calmed down.

"Although the test flight work is going well now, it will take a certain amount of time to confirm the mass production model, at least half a year."

"Even after the fighter jets are finalized, there are still many problems in the mass production of fighter jets."

"There are many problems in terms of materials, production equipment, and personnel."

Zhang Xingyang also knows that in the process of mass production, he will encounter many problems.

However, these problems have made the J-10 fighter develop in a good direction.

The process of solving these problems may be painful, but watching the J-10 fighter jets develop little by little, everyone is in a happy mood.

"There are problems, but they can be solved through our efforts."

"I'm here this time to solve your problems!"

This time Zhang Xingyang came here specially to solve the material problem in the future mass production of J-10.

"If there is anything we can do, you can directly bring it up."

"The carbon-carbon composite material you developed last year has really good performance. We plan to use a similar material on the J-10's brake disc."

"Can your follow-up production capacity keep up?"

Song Tianxing mentioned the carbon-carbon composite material successfully developed by the Rocket Research Institute last year, and the brake disc that he wanted to use on the J-10.

Before the Rocket Research Institute successfully developed carbon-carbon composite materials, domestic achievements in this area were almost blank.

The brake discs of fighter jets need to use high-performance materials that can withstand high temperatures and wear.

Previously, due to insufficient material performance, the J-10 fighter had to use a deceleration parachute to reduce the speed of the aircraft when returning to the landing.

Fighters from other countries in the same period, especially Western fighters, only need to open the speed brake when landing, and they can rely on the brake disc to slow down.

It can be said that the Rocket Research Institute has filled the gap in this area in China on its own.

"The factory has been trying to find ways to increase production capacity."

"Within this year, after the new production equipment and workers are in place, the annual production capacity is expected to increase to 200 tons, which is enough for you to use."

"However, if you can produce hundreds of them a year, the production capacity may not be enough."

Of course Song Tianxing knew that Zhang Xingyang's last sentence was a joke.

The initial annual output of the J-10 fighter jets would be good if there were a hundred of them.

"I also want to produce hundreds of J-10 fighter jets every year, so that the Air Force can replace them with our own fighter jets."

"It's a pity that the conditions in all aspects do not allow it."

Song Tianxing said helplessly, but also lazily.

"However, besides the brake disc, we still need to trouble you in some places."

"I don't know what the maximum size of the composite material you can achieve. We intend to use composite materials on the engine intake and aircraft wings in subsequent improvements."

"I just don't know how big your size can be. After all, the wings of the plane are several meters long."

The aircraft uses composite materials, which can greatly improve the strength of the aircraft and reduce the weight of the aircraft.

However, although the performance of composite materials is good, the price is still much more expensive than the aviation aluminum alloy used in the original aircraft.

Composites are priced almost by the gram.

Zhang Xingyang didn't know whether the other party could bear such a cost.

"The price of large-scale composite materials is very expensive. Can the Air Force afford such manufacturing costs?"

"These costs are nothing, and the Air Force can accept them as long as the price of a single machine is within 180 million."

It's hard to say that this price is expensive. You must know that the price of a single Su-27 fighter jet imported from Damao's family in China has been 30 million US dollars.

Converted into domestic currency, the price of a single Su-27 fighter jet is about 250 million.

"Since they are not afraid of spending money, I can also say it very clearly."

"The production and manufacture of large-scale composite materials is not difficult!"
