Engines for large transport aircraft and other products made a debut at the indoor exhibition hall of the 2025 aviation open-day activities of the Chinese People's Liberation Army Air Force and Changchun Air Show which opened on Friday.
This marks the first time that Aero Engine Corporation of China (AECC) participated in the event in Changchun, northeast China's Jilin Province ) as an exhibitor.
"We can see the engine is huge, over two meters tall. This is the domestically produced engine for our large transport aircraft, China's first high bypass ratio dual rotor turbofan engine, featuring a full-authority digital engine control and health management system," said Liu Jie, a staff of AECC, as she introduces the exhibition.
The air show also displayed three domestically produced Taihang turbofan engine series.
"The Taihang turbofan engine series is a turbofan engine with high thrust developed entirely in China. It has embarked on a development path characterized by serialized production and continuous performance enhancement. We have completed technological upgrades in its performance reliability, safety, as well as its stealth and thrust vectoring, giving our aircraft a strong boost in both combat effectiveness and survivability," said Liu.
In addition to domestically produced aero engines that can be equipped on large transport aircraft, exhibits including engines designed for unmanned aerial vehicle (UAV) power were also displayed.
"This is the F918 engine we are publicly displaying for the first time. It boasts a thrust of 2,000 kilograms and can achieve an operational altitude of 20 kilometers. It is suitable for application in high-altitude, high-speed reconnaissance strike integrated UAVs (unmanned aerial vehicle). What we are looking at now is a 500-kilowatt-class turboprop engine AEP50. The section here is its combustion chamber, and behind it is the turbine," said Liu.
"It serves as the engine for Wing Loong Ⅱ UAV. We have also developed numerous derivative models based on it, enabling adaptation to the diverse mission requirements of different customers under all-weather conditions and across multiple regions," she continued.
