After reading the book, the address of [Wanbenshen Station]: Avoid the pain of chasing books!

Yonghan Aviation Technology Co., Ltd. has basically invested tens of billions of dollars every year in recent years, and has become a first-class aero engine company in China in terms of software and hardware, and will not have greater investment in hardware in the future, and the main investment at this stage is in the research and development of aero engines.

The research and development of this Kunlun turbofan engine has invested more than one billion yuan, and now the price of such a one is more than 10 million, which can be said to be a conscience price compared to the engines provided by Russia and Ukraine.

However, this engine has to sell at least more than 400 units to make a profit, and it takes at least five or six years, and the engine has not yet obtained the airworthiness certificate, so it can only rely on the domestic market for the time being.

This Kunlun turbofan engine is also in Yongzhou high-altitude platform for various test tests, but from the performance point of view, this turbofan engine performance in all aspects, although there are some needs to be improved in the design, but the performance has been stronger than the engine designed and produced by Pratt & Whitney and Weide in the nineties.

The overall technical strength of Yonghan Aviation Power Technology Co., Ltd. has been squeezed into the second echelon, and it is stronger than Russia in material technology.

It's quite a feat to get to this point.

At present, Yonghan Aviation Power Technology Co., Ltd. is also providing Pratt & Whitney and Bombardier Group companies in OEM engine components, in addition, the test test of Hengshan small bypass ratio turbofan engine in the high-altitude platform has been completed, and by the end of this year, Chengfei, Hongdu Aviation Group, and Xifei Aviation Group will provide 160 units, and 50 or 60 small-thrust turbofan engines have been sold.

Yonghan Aviation Power Technology Co., Ltd. has now begun to provide aero engine materials and process licenses to these domestic airlines, and has almost earned more than one billion.

OEM plus material and process licensing and the sale of engines have made the company's revenue close to more than 4 billion this year, compared with Yang Jie's investment of nearly 40 billion in recent years, the company is still in a state of loss.

However, these are not one-shot deals, as the sale of these engines is more profitable than selling the engines directly, and the larger the number of engines sold, the more profit Yonghan Aero Dynamics will make in these areas.

Some of Yonghan Aviation Power Technology's technology has begun to spread to the fields of other Huaxing Group subsidiaries, and more and more profits will be obtained in the future.

Moreover, the Hengshan turbofan engine has passed the airworthiness certification of the FAA and EASA under Yang Jie's activities, because Yonghan Aviation Power Technology Company strictly follows the various standards of Rolls-Royce for production management, and it is still very smooth to pass these audits.

It is precisely for this reason that Bombardier Group also purchased a batch of Hengshan turbofan engines from Yonghan Aerodynamic Technology Co., Ltd. for testing on its business jets, and several small aircraft manufacturers also signed contracts with the company for the purchase of Hengshan engines.

The price of Hengshan series engines is more advantageous than similar products in terms of fuel consumption and price, and these companies are naturally very interested.

The load-bearing flight test flight of Yun 8K was successfully completed, which made the military bigwigs very satisfied, and Yang Jie also received a call from the head of Yang Ziguang No. 1.

Yang Ziguang also praised Yang Jie on the phone, and mentioned the recent inspection of Yonghan Aviation Power Technology Company.

This made Yang Jie quite excited, and said with a smile on the phone: "Our company warmly welcomes the chief's inspection of our company, and also hopes that the chief can give some guidance for the development of our company." ”

Chief Yang smiled on the phone, and after saying a few more words, he hung up the phone.

Wang Yonglin and others saw that the No. 1 chief was talking directly to Yang Jie, and their eyes showed surprise, their boss has a very close relationship with the senior management, which is definitely an excellent thing for Yonghan Aviation Power Technology Company.

Yang Jie was quite happy in his heart, and after putting down the phone, he smiled at Wang Yonglin and said: "You have done a very good job, I will ask the secretariat to allocate a bonus to reward all the personnel of the company." ”

Wang Yonglin and the others were all smiling.

A week later, Yang Ziguang, accompanied by a group of officials, inspected Yonghan Aviation Power Technology Company, and Yang Jie, Li Kaiyuan and other provincial party committee officials also accompanied the whole process.

Yang Ziguang saw that the assembly workshop was busy assembling the engine, everything was in order, and he nodded frequently.

"It's amazing that Yonghan Aviation Power Technology has been able to do this in a few years!" Yang Ziguang said.

"The main thing is the support of the leaders and the provincial party committee. Yang Jie said.

"It's your own struggle," Yang Ziguang glanced at Yang Jie, Wang Yonglin and the others, "You kid is really a good means, you can find so many talents to gather together to develop engines." ”

Yang Jie smiled: "I'm also lucky." ”

"People who have the ability say they are lucky. ”

Yang Ziguang said with a smile: "I heard that you are working on electric propulsion turbofan engines, what progress has you made now?"

"Chief, do you know this?"

"Several comrades of the Military Commission told me about the development of electric propulsion turbofan engines by Yonghan Aviation Power Technology Company, since you attach so much importance to it, it must be a great project. ”

Yang Jie then took Yang Ziguang to a laboratory of Yonghan Aviation Power Technology Company to visit the arc heater being developed.

On the test bench at this time, a cylindrical device with a diameter of half a meter and a meter and a half of a length is placed, and it is covered with various cables.

The heater is coated with a heat-insulating composite ceramic coating and has a small flared spout at the tail.

The heater was developed by Konstantin and Zhao Dexin, a 40-year-old deputy chief designer of the 11th Academy of Huaxia Aerospace Group Corporation, responsible for the construction of the arc wind tunnel and the research and development of the arc engine.

The Huaxia arc engine project began ten years ago, and Zhao Dexin designed and built two telephone wind tunnels with a diameter of half a meter, which are also the only two in China.

He has a deep foundation in arc heating technology and pneumatic layout, Yang Jie also found him through the relationship, after explaining that Yonghan Aviation Power Technology Co., Ltd. wants to use arc heating technology to develop the technical scheme of electric propulsion turbofan engine, Zhao Dexin resigned and joined the team, and also brought several technical backbones.

Yonghan Aviation Power Technology Co., Ltd. has sufficient R&D funds, and many companies of Huaxing Group have also provided support, and an arc heater has been developed in less than two months, and has been tested and verified for a period of time.

Yang Jie also asked Zhao Dexin to start this set of heating equipment.

There was a dense popping sound inside the heater, and then the tail nozzle sprayed a powerful high-temperature air current, and the air at the exhaust port was visible to the naked eye to produce strong fluctuations!

The heater was tested for about 10 minutes and then stopped.

"How can such a small heater have such a powerful airflow?" Yang Ziguang asked.

"Chief, we injected high-pressure air into the heater, reaching 10 megapascals, which is three times higher than the pressure of the existing turbofan engine, and the temperature of arc heating is very high, and there must be a high-pressure gas with sufficient pressure to quickly dissipate heat, otherwise it is easy to ablate the internal structural components. ”

Zhao Dexin said.

"You proposed this technical solution?" Yang Ziguang looked at Yang Jie and asked.

"Yes, but I'm just offering an idea, and the specific research and development is still up to these experts in the company. ”

Yang Jie said: "Now Europe and the United States have matured in low-power arc engines, they are used in satellites, and I want to use them in civilian engines." ”

"Our Huaxing Group has now prepared a high-speed and high-voltage switch with gallium nitride materials, which can control the arc more accurately and with higher efficiency, which is our technical advantage. ”

"Well, the country is now advocating innovation, and you are creatively using arc heating to develop a new type of aero engine, which is a great idea!"

Yang Ziguang nodded.
