An Aero Turbogenerator Engine is a high-power gas turbine-based range-extending power system specially developed for low-altitude aircraft, unmanned aerial vehicles (UAVs), and electric vertical take-off and landing (eVTOL) platforms.

It integrates a high-speed gas turbine core engine with an ultra-high-efficiency synchronous generator in a compact series layout. Unlike traditional turbojet engines that produce thrust directly, the turbogenerator converts fuel energy into high-quality continuous electric power to supply propulsion motors, airborne equipment, and battery charging for hybrid-electric aircraft.

• Extreme Power Density & Lightweight Integration: Advanced turbine core and high-speed generator integrated structure provides extremely high power output within limited volume and weight.
• Dramatically Extended Endurance & Payload Capacity: Compared with pure lithium battery electric propulsion of the same weight, increases flight range up to 6 times and improves payload capacity up to 3 times.
• High-Altitude & Full-Environment Adaptability: Stable and reliable power generation at high altitude, low temperature, and low air density environments.
• Intelligent Hybrid Power Support: Provides stable continuous power for AI autonomous flight systems, flight control units, sensors, and heavy-duty propulsion units.
• High Reliability & Industrial-Grade Durability: Mature gas turbine architecture with fewer vibrating moving parts and advanced thermal management design.
• Wide Application Compatibility: Applicable to fixed-wing UAVs, hybrid-wing aircraft, helicopters, and multi-rotor eVTOLs for range extension, payload enhancement, and full-aircraft power supply.

Turbojet Engine: Produces jet thrust for high-speed flight

Turbogenerator Engine (Our Product): Produces large continuous electric power for hybrid-electric long-endurance flight

This core difference makes our aero turbogenerator the ideal next-generation power solution for low-altitude economy and long-endurance unmanned aviation.

The WD-200, WD-300 and WD-500 aero turbogenerator engines are advanced aviation power units independently developed by our company. Tailored for civil aircraft in the low-altitude economy, they fill the domestic market gap for 200 kW, 300 kW and 500 kW aero turbogenerator engines.

These products adopt high-performance general core engines self-developed by Star Aero Engine. They feature an innovatively designed series power architecture combining aero-engine and ultra-high-speed generator. Widely applicable to fixed-wing, hybrid-wing, helicopter, eVTOL and other medium-to-large manned and unmanned aircraft.
