Example methods, systems, and articles of manufacture may relate to an aerial vehicle. The methods, systems, and articles of manufacture may include receiving an audio signal with a microphone of the aerial vehicle. The methods, systems, and articles of manufacture may also include processing the audio signal to determine at least one of a distance and type of aircraft located near the aerial vehicle. Additionally, the methods, systems, and articles of manufacture may include, based on the determination, performing at least one maneuver of the aerial vehicle.

Audio based aircraft detection

An aerial vehicle includes an airframe; vertical propulsion units, and a controller. The vertical propulsion units are mounted to the airframe and include propellers oriented to provide vertical propulsion to the aerial vehicle. The vertical propulsion units are physically organized in quadrants on the airframe with each of the quadrants including two or more of the vertical propulsion units. The controller is coupled to the vertical propulsion units to control operation of the vertical propulsion units. At least two of the vertical propulsion units in each of the quadrants are adapted to counter-rotate from each other during flight of the aerial vehicle.

Counter-rotating propellers for aerial vehicle

A technique of controlling tonal noises produced by an unmanned aerial vehicle (UAV) includes generating thrust with a plurality of rotor units mounted to the UAV to propel the UAV into flight. Each of the rotor units includes a bladed rotor. A rotation rate or a phase delay of at least one of the rotor units is adjusted relative to another of the rotor units. The adjustment causes a spread in the tonal noises generated by the rotor units.

Multi-rotor tonal noise control for UAV

A propulsion unit includes a motor rotor that spins about a central rotational axis, propeller blades each having a proximal base and a distal tip, and pivot mounts each coupling the proximal base of a corresponding one of the propeller blades to the motor rotor. The propeller blades each freely pivot at the proximal base about a corresponding offset pivoting axis that is substantially parallel to but offset from the central rotational axis of the motor rotor.
