China's AS700D electric manned airship has completed a successful maiden flight,
marking a major breakthrough in green aviation equipment in the low altitude economy sector,
according to the Aviation Industry Corporation of China, the airship's developer.
The milestone verified the technical maturity and principles of China's independently developed as 700D,
laying the foundation for the development of subsequent electric airships.
During the maiden flight, which was carried out in Jingmen in central China's Hubei Province,
the airship conducted a vertical takeoff and then quickly climbed to an altitude of 50 meters.
After briefly hovering, it performed a vertical landing and then stopped steadily.
Pilot Lin Hong recalled that the flight of the electric airship felt light and smooth,
just like driving a new energy car.
The AS 700D is a new type of all electric airship with a comprehensive electrification upgrade based on the AS 700 manned airship,
which uses aviation gasoline as fuel.
It utilizes an advanced lithium battery, electric drive system, propeller system,
thrust vector control system and cooling system to replace the aero engine and fuel system.
