US Army successfully flies a hybrid electric drone with 3D-printed heavy-fuel rotary engine — 400v motor-generator uses advanced engineering to ditch a bulky liquid cooling system
The U.S. Army demonstrated a hybrid electric drone powered by a 400-volt motor-generator using a 3D-printed rotary engine designed to burn heavy fuel. The advanced engineering eliminated the need for bulky liquid cooling systems, representing progress in electric aviation propulsion. The project combines additive manufacturing with hybrid-electric technology.
Key points
- 400v motor-generator with heavy-fuel rotary engine
- 3D-printed components reduce system weight
- Eliminates liquid cooling complexity
