Flying vertically is loud.
Electric Vertical take-off and landing (EVTOL) promises to radically change the transportation landscape for people and cargo. However, noise is a pain point that limits acceptance in civilian markets and increases risk for military users.
Ultra-Quiet Propulsor
We’ve developed a propulsor that is 8x quieter and 50% more efficient than a drone (multi-rotor) design. The patent-pending technology is already 15 dB quieter than emerging EU noise standards and has dual-use potential in civilian and military markets.
Custom Propulsors for Drones and Manned Aircraft
Our flight-proven propulsors can scale to any size and configuration. Contact us to learn how we can develop a custom quiet propulsion system for your aircraft.
