LiquidPiston Tech Stack

Compact rotary engines and hybrid propulsion for UAVs and aircraft

Motor Vehicle Manufacturing Bloomfield, CT 11–50 employees Privately Held

LiquidPiston designs rotary engines with a 10x smaller footprint and 30% higher efficiency than conventional piston engines, targeting drone and aircraft propulsion systems. The tech stack—SolidWorks, CATIA, ANSYS, Simulink, LabVIEW—reflects a hardware-first design cycle with heavy simulation and control-system integration. Active projects center on UAV propulsion architectures and hybrid-electric platforms, while pain points cluster around manufacturability, seal optimization, and supply-chain scaling—typical constraints for a compact engine startup moving from prototype to production.
