ROTOR UNITS HAVING ASYMMETRIC ROTOR BLADES An aerial vehicle is provided comprising a plurality of rotor units connected to the aerial vehicle, wherein the plurality of rotor units (710, 720, 730, 740, 750) is configured to provide thrust to the aerial vehicle, and wherein at least one rotor unit of the plurality of rotor units (710, 720, 730, 740, 750) comprises: two or more rotor blades, wherein each rotor blade of the two or more rotor blades comprises a surface area, and wherein an asymmetric parameter is defined, at least in part, by the relationship between the surface areas of the two or more rotor blades; a control system (1120) configured to operate the at least one rotor unit, wherein the value of the asymmetric parameter is such that the operation of the at least one rotor unit: (i) moves the two or more rotor blades such that each rotor blade produces a respective vortex and (ii) the respective vortices produced by the two or more rotor blades cause the rotor unit to produce a sound output having an energy distribution defined, at least in part, by a set of frequencies, wherein the set of frequencies comprises a fundamental frequency, one or more harmonic frequencies of the fundamental frequency, and one or more non-harmonic frequencies of the fundamental frequency having a respective strength greater than a threshold strength.
