Patent Images
1. An unmanned aerial vehicle (UAV) comprising:
- a frame;
a propulsion system associated with the frame, the propulsion system comprising;
a first motor associated with a first propeller of a first size, anda second motor associated with a second propeller of a second size; and
a computing system configured to manage the propulsion system during a flight associated with delivery of a payload to a location, the computing system configured to;
modulate, from the first motor to the second motor based in part on a sound generated by the UAV during the flight to the location;
obtain input that identifies activation of a release mechanism of the UAV to deliver the payload to the location; and
instruct modulation of the first motor and the second motor based at least in part on the input.

Abstract
Techniques for using an unmanned aerial vehicle (UAV) to deliver a payload while reducing and/or altering sound generated by the UAV during delivery may be provided. For example, during delivery, the UAV may be instructed to utilize one or more sets of propellers of different sizes to reduce and/or alter the sound generated by and/or around the UAV. Intrinsic and extrinsic information associated with the UAV may be utilized to dynamically adjust the particular sets of propellers of a certain and different size to utilize during different portions of a flight path while delivering the payload.
