After the success of the first flight of the J-10, a number of long-term test flights began immediately, testing the flight data of the J-10 fighter almost uninterruptedly.

In particular, the data under various limit states, such as limit rise, ultimate flight speed, maximum range, maximum take-off weight, etc.

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

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

The J-10 fighter in this life has a small increase in performance compared with the previous life.

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

"Dean Zhang, it's hard for you to run again."

Song Tianxing, as the chief engineer of the Jian-10 project, warmly shook Zhang Xingyang's hand from afar.

More than a month has passed since the first flight of the J-10.

Song Tianxing has been in a good mood during this time because of the success of the first flight of the J-10, and the whole person is visibly mellow with the naked eye.

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

Both sides were in a good mood, and Zhang Xingyang also made a small joke.

"Hahaha, isn't this the first flight of Jian-10 successful, when the mood is good, the appetite will be good!"

"Chief Master Song, how is the current flight situation of the J-10, 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 I am my own child, I can't help but care.

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

Speaking of the turbofan 10 engine, Song Tianxing was like a child mentioning his beloved toy, and he was very excited to introduce the performance of the turbofan 10 on the Jian-10 fighter.

"We even tested it with an AL-27F that was removed from the Su-31 from the Air Force and a turbofan 10 engine."

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

"So that our planes can fly farther and higher!"

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

It's as if parents are genuinely happy when they see others praising their children!

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

Zhang Xingyang is very self-aware and does not think that the other party's praise is all for himself, and there are many people who should actually accept these praises.

"Chief Master Song, how long do you think it will take for our J-10 to mass-produce equipment troops?"

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

"Although the test flight work is going on well, it will take a certain amount of time to determine the mass production model, not to mention more than half a year."

"Even after the finalization of the fighter, there are many problems in the mass production of fighters."

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

Zhang Xingyang also knows that there will be many problems in the process of mass production.

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 develop little by little, everyone's mood is joyful.

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

"I'm here to solve your problems!"

This time, Zhang Xingyang specially rushed over to solve the material problem in the mass production process of Jian-10 in the future.

"If there's anything we can do, you can just ask."

"The carbon-carbon composite material we developed last year has really good performance, and we plan to use similar materials on the brake disc of the J-10."

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

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

Before the successful development of carbon-carbon composite materials by the Rocket Research Institute, the domestic achievements in this area were almost blank.

Fighter jet brake discs need to be made of high-performance materials that can withstand high temperatures and wear and tear.

Previously, due to the lack of material properties, the J-10 fighter had to use a parachute to reduce the speed of the aircraft when it returned to land.

At the same time, fighters from other countries, especially Western fighters, only needed to open the speed brake plate when landing, and they were able to rely on the brake disc to slow down.

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

"On the factory side, we have 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 be increased to 200 tons, which is enough for you."

"But if you can produce hundreds of planes a year, it may not be enough."

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

The initial annual output of J-10 fighters is good to be able to have a hundred.

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

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

Song Tianxing was a little helpless, and also said a little slack.

"But we have something to trouble you in addition to the brake discs."

"I don't know what the maximum size of the composite material you can make, but we intend to use composite materials in the engine intake tract and aircraft wing in the subsequent improvements."

"I just don't know how big you can be, after all, the wings of planes are several meters long."

The use of composite materials in aircraft can greatly increase 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.

The price of composite materials is almost calculated by grams.

Zhang Xingyang also didn't know if the other party could afford such a cost.

"The price of large-scale composite materials is very expensive, can the Air Force afford such a manufacturing cost?"

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

It is difficult to say that this price is expensive, you must know that the single price of the Su-27 fighter imported from the Da Mao family in China has been 30 million US dollars.

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

"Since they're not afraid to spend money, I can be very clear."

"There is no difficulty in the production and manufacturing of large-scale composite materials!"
