On June 5th, the inaugural AEE25 aviation electric engine—developed independently by the China National Aeronautical Propulsion Technology Research Institute—was successfully rolled off the production line and prepared for delivery. Tailored specifically for electric vertical takeoff and landing (eVTOL) aircraft, this engine incorporates six core components: the main motor, main motor controller, cooling system motor and its controller, as well as the variable-pitch actuator and its controller. These components are seamlessly integrated into a single unit, achieving a "six-in-one" design that represents the highest level of integration for aviation electric engines in China.
This milestone delivery signifies a major breakthrough in China's development of key technologies for aviation electric engines, with performance metrics now on par with international advanced standards.
