According to CCTV, the official WeChat public account of the aviation industry recently stated that China's independently developed large-scale amphibious aircraft "Kunlong" AG600M recently completed its last high-cold test flight mission in Hailar, Inner Mongolia. The test flight mission, which lasted about two weeks, was carried out at minus 20 degrees Celsius. The functional performance test of each system of the entire aircraft was carried out under conditions ranging from ℃ to minus 40 ℃. This is the longest transition mission with the most complex route environment that the AG600M has performed since its first flight.
According to reports, during this high-cold test flight mission, the "Kunlong" amphibious aircraft's power plant system, fuel system, hydraulic system, flight control system, avionics system, landing gear system and other key systems passed the high-cold ground test and test flight It has been verified that in the future, it can meet the needs of forestry, firefighting, search, rescue and other fields throughout China.
According to reports, two "Kunlong" AG600Ms (1003 and 1005) were transferred to Inner Mongolia Hailar Dongshan Airport on January 22 and 30 respectively after a long journey of more than 2,200 kilometers for nearly 6 hours, opening up the low-temperature environment. Related verification tasks.
This Hailar high-cold special test flight verified the aircraft's low-temperature, defrosting, snow removal and other maintenance procedures, laying a solid foundation for airworthiness certification and subsequent use and maintenance in low-temperature environments.
It is understood that the development work of the "Kunlong" AG600M fire-fighting aircraft has fully entered the critical stage of airworthiness compliance verification, and it is planned to obtain the type certificate in 2024. (Wuhan Evening News)
