US Army flies hybrid electric drone with 3D-printed heavy-fuel engine

By PulseAugur Editorial · [1 sources] ·

The U.S. Army has successfully flown a hybrid electric drone, named VICTOR, which features a 3D-printed heavy-fuel rotary engine. This advanced engine design utilizes an air-cooling system, eliminating the need for a bulky liquid cooling setup. The engine powers a 400-volt motor-generator, which in turn drives the drone's propellers, allowing for optimal engine performance independent of propeller speed. AI

IMPACT This development showcases advancements in hybrid-electric propulsion for unmanned aerial vehicles, potentially impacting future military logistics and operational capabilities.
