The four-seat hydrogen-powered internal combustion aircraft prototype made its first flight the day before in Shenyang, a city in northeastern China's Liaoning Province. Xu Xiaoben, who served as a test pilot, said that the plane had sufficient power and acceptable vibration at a flight altitude of 200 meters. The aircraft is 8,2 meters long and has the capacity to store up to 4,5 kilograms of high-pressure gaseous hydrogen. The maximum thermal efficiency of the hydrogen internal combustion engine of the aircraft, which travels at a speed of 180 kilometers per hour, is over 43 percent.
Sun Xiaoping, chief technologist at Liaoning General Aviation Academy, said that with the aviation industry's growing interest in clean energy and stricter control of carbon emissions, aircraft using hydrogen fuel will become more preferred in the future.
The verification model of the aircraft made its first flight in Shenyang on March 25, 2023. Validation model, FAW Group Co., Ltd. It is equipped with a zero-emission, supercharged, 80 kW direct injection hydrogen combustion engine developed by . This aircraft is the first independently developed general aviation aircraft powered by a hydrogen internal combustion engine in China.
