Yang Jie also hopes that his company can take root in Damao's territory, after all, he also hopes that the company he founded can operate overseas for a long time, rather than a company that leaves after making money in a country.

In recent years, the domestic economic situation of Damao has been very poor because of the war, and because of economic sanctions, many companies have withdrawn from Damao, in this case, Huaxing Group Company must be more prepared to take root in Damao, after all, Damao has a population of hundreds of millions in China, and it is also a very large market, and Huaxing Group will never easily give up this market.

President Vladimir then also visited the company and also visited the production line of the F150.

Now the F150 has obtained the airworthiness certification of the European Aviation Agency, and the Netherlands is also the first to order a few, in order to reduce the resistance to export, China Fokker has also purchased a lot of parts from Europe in domestic joint ventures, and also purchased some aero engines from Rolls-Royce and Safran.

Of course, this passenger aircraft is also indispensable to the high-performance aero engine provided by Yonghan Aviation Technology Company.

In order to make the aero engine reliable, the designed engine takes a very long time from the ground test to the high-altitude test, in order to shorten the test cycle, and there are many types of engines to be tested, so the company continues to build ground and high-altitude experimental platforms, and the test test has hardly stopped for a year, the intensity is very large, and at least five or six billion yuan is consumed in hardware facilities and test costs every year.

At present, the time from design, manufacturing and production to the completion of testing has been compressed to two years, and the time from subsystem components to the main engine test of an engine is more than 100,000 hours.

It is precisely because of this that the engines produced by the company have ultra-high reliability, high thrust and are also very fuel-efficient, easy to maintain, and cheap, and immediately welcomed by many domestic and foreign airlines.

In order to promote this engine, Yonghan Aviation Technology Company also made a guarantee to many airlines, the engine parking rate exceeds the standard, directly to the airline to lose money, the return rate is promised to be 1000 flight hours 0.039 times, if the first stop within a year direct compensation of 200,000 US dollars, the second time 350,000 US dollars, the third time after each compensation of 600,000 US dollars!!

For the second type of failure, such as engine surge, the company has issued an equally generous compensation clause, and if the airline cancels the flight due to engine failure, the company also has a corresponding compensation standard.

The company's ability to make such a high subsidy standard is also a confidence in the performance and reliability of its own engine products, because the standards of each engine are even more stringent than foreign tests.

At the same time, Yonghan Aviation Technology Co., Ltd. also generously invited many aviation manufacturers and airlines to visit the engine production and testing base of Yonghan Aviation Technology Co., Ltd., which is also to show the company's strong financial strength and high degree of rigor and seriousness in treating products to the outside world.

Therefore, the engines produced by Yang Jie's personal company are also very popular overseas, and they have grabbed a lot of orders from Pratt & Whitney, Safran, GE, and Rolls-Royce.

The regional airliners delivered by COMAC to customers at home and abroad are basically purchased from Yonghan Aviation Technology Company.

The engines provided by Yonghan Aviation Technology have been carried on many passenger aircraft for more than a million hours, with no stopping and no surge, and the performance reliability has been fully proven.

There was also an incident in which the engine of an F100 passenger plane failed and forced to land after sucking into a bird, and after testing, it was found that the blades were broken and the debris injured the low-pressure turbine blades.

Although the company has also done a lot of bird impact tests, in the design as far as possible to prevent the fan blades from being broken and causing damage to the compressor and other components inside the engine, but this situation is also difficult to avoid, because there are too many uncontrollable factors.

Yonghan Aviation Technology Co., Ltd. has worked hard in terms of control system, software, hardware and the whole machine after digging a technical team with rich work experience at home and abroad, and has also hollowed out the best engineers and technicians in China to develop the manufacturing process and manufacturing of parts and components of the core machine, including wax molds and ceramic cores.

For example, the manufacturing and processing technology of single crystal high-temperature materials, composite materials, carbon fibers, and high-performance resins are all completed by integrating all the strength of Huaxing Group.

The company racked its brains to complete the construction of the experimental test platform on the ground and the high-altitude platform, and these integrated systems were not given abroad, so they scattered to buy subsystems and integrate them themselves, which was more difficult than fighting a war.

Over the years, Yang Jie has spent almost more than 10 billion US dollars in this regard, and finally completed the entire process and industrial chain of aero engines, and the company has gathered more than 7,000 engineering and technical personnel, and now the company basically delivers about 3,000 military and civilian engines every year, plus engine parts and maintenance, OEM and high-end material supply and other businesses, with a turnover of about 7 billion US dollars.

Although Yonghan Aerospace Technology's engine business is still very small compared to GE, Pratt & Whitney, Safran and Rolls-Royce, it is remarkable for a company that has only been established for less than eight years.

After all, these aviation giants have been working hard to engage in research and development and compete for the market over the years, and they are not idle, and GE's aero engine business is still a stable revenue, with revenue of more than 20 billion US dollars, and operating profits can reach more than 20 percent.

Of course, Yonghan Aviation Technology Company is not bad in this regard, at least it has a firm foothold, although there are a few engines that sell well and lose money, but several engines are very popular, especially the derived 3D printing high-precision nozzles, high-energy ignition devices, aircraft navigation systems and sensors, weather radar, electronic pods, Aircraft headlight lighting system, cabin air and thermal management system, auxiliary power system and power system and other equipment and parts are very profitable, and our own company purchases and wants to supply domestic customers.

In addition, the company's profits in the supply of special materials are also very high.

Yonghan Aviation Technology Co., Ltd. now has a combined annual sales of about 14.8 billion US dollars, and the profit margin is very high, and Yang Jie's persistence over the years has also begun to get huge returns.

Although the turnover of Yonghan Aviation Technology Company is not as good as that of several companies such as Huaxing Communication Equipment Company, Xinlan Technology and Aihua Technology Company, and Zhongyuan Automobile Group Company, which are subsidiaries of Huaxing Group, there is no comparison between these companies.

President Vladimir's expression was also quite complicated when he saw the large bypass ratio turbofan engine provided by Yonghan Aviation Technology Company on the passenger plane.
