Shulou(Shulou.com)11/24 Report--

Thanks to CTOnews.com netizen grass Luo Yuzi for the clue delivery! CTOnews.com February 18, Wuhu, Anhui announced that the AEC2.0L piston engine, the first domestic civil aircraft piston engine to carry out airworthiness certification in the China Civil Aviation Airworthiness Certification Center, has successfully verified its compression ignition capability and high-altitude start-up ability, thus completing various established capability verification projects for airworthiness certification.

According to reports, China's first general-purpose aircraft equipped with domestic AEC2.0L aero-engine, CA42, successfully completed its test flight on February 16.

It is worth mentioning that the Chinese-made AEC2.0L aero-engine was carried in the domestic civil navigable aircraft CA42 independently designed and manufactured by China Electric Power Wuhu Diamond aircraft Manufacturing Co., Ltd. Such a "double domestic" match is the first time in the domestic civil aviation industry.

In order to ensure the sufficient safety and reliability of the engine in flight, the flight test is divided into several height points, which has the characteristics of long preparation period, many limiting factors, difficult operation and so on. The purpose of this paper is to verify the compression ignition ability and restart ability of the AEC2.0L engine in the air, and fully prove that the domestic civil aviation piston engine can meet the needs of modern civil aviation.

"this engine is developed independently by Chinese enterprises, and its comprehensive performance is comparable to the international first-class level, and it has also broken the foreign monopoly in one fell swoop!" Hou Xiaoyu, deputy director of the system approval room of China Civil Aviation Airworthiness Accreditation Center, said.

Jiao Yanbin, deputy general manager of Wuhu Diamond Aeroengine Co., Ltd., said that the engine has solved a series of "sticking neck" problems of software and hardware key technology. this is also a "summary test" of domestic civil aviation piston engines from conception to drawing data to finished products, which fully proves that domestic civil aviation piston engines can fully meet the needs of modern navigation.

You may wonder, how does this engine compare with the engine used in another popular domestic aircraft, the C919?

According to public data, Comac, as the manufacturer of the C919, purchased the LEAP-1C engine through CFM, while there are three models of LEAP series engines, while the C919 purchased this LEAP-1C engine with low thrust and differences in other parameters, but it can fully meet the flight needs.

Some people may be unhappy with the use of non-domestic engines in the C919, but you should know that the C919 project has been going on for more than a decade, at least 16 years before and after delivery, and the remaining two engines of the CFM LEAP series are used by Airbus A320NEO and Boeing 737MAX, and there has been no major failure since they were put into commercial flight.

As CTOnews.com has been following up all this time, the C919 is currently in the 100-hour verification flight, and if the flight is successfully completed, it will be put into commercial operation in the spring. According to the plan of China Eastern Airlines, the time for commercial operation is likely to be in early March.

So far, the C919 is still the first self-developed wide-body airliner project in China, and it is also the only domestic large aircraft ready to be put into commercial operation.
