The technology is an ultra-light, quasiactive noise control method for quieting unmanned aerial vehicles (UAVs). This passive noise reduction method for propellers is tunable to various flight conditions and directions. The design will reduce the acoustic emissions of UAVs without significantly impacting vehicle performance. Reducing UAV acoustic noise can lower the minimum altitude and lower the payload cost. This system can be used on propeller driven fixed wing vehicles and tail rotors of rotary wing aircraft.
