1. A computer-implemented method, comprising:
- receiving, by a computer system, an order to deliver a package associated with an electronic marketplace;
generating, by the computer system, a flight plan that instructs an unmanned aerial vehicle (UAV) to deliver the package based in part on information associated with the order;
generating, by the computer system, a sound profile based in part on one or more sets of propellers that are associated with the UAV, the sound profile identifying an expected sound that corresponds to utilizing the one or more sets of propellers simultaneously during flight of the UAV to generate a noise cancellation effect, a set of propellers of the one or more sets of propellers being a different size than another set of propellers of the one or more sets of propellers;
instructing, by the computer system, the UAV to fly to a location associated with the delivery of the package utilizing the flight plan; and
instructing, by the computer system, modulation of each propeller set of the one or more sets of propellers simultaneously during at least a portion of the flight plan to generate the expected sound by the UAV.

Abstract
Techniques for using an unmanned aerial vehicle (UAV) to deliver a payload while generating an expected sound by the UAV during delivery may be provided. For example, during delivery or while in flight, propellers of different sizes that are associated with the UAV may be instructed to modulate at different rotational speeds to thereby generate an expected sound.

5. A computer-implemented method, comprising:
-
receiving, by a computer system, an order to deliver a package; instructing, by the computer system, an unmanned aerial vehicle (UAV) to deliver the package to a location associated with the order; instructing, by the computer system, a first sensor associated with the UAV to emit a signal to a surrounding environment of the UAV during flight, the signal emitted within a particular distance around the UAV; receiving, by the computer system and from a second sensor associated with the UAV, information identifying the signal reflected off the surrounding environment and received by the second sensor; identifying, by the computer system, a sound propagation of the surrounding environment of the UAV during flight based in part on the information received by the second sensor associated with the UAV; and instructing, by the computer system, the UAV to fly to the location and modulating one or more sets of propellers that are associated with the UAV simultaneously during at least a portion of the flight to generate an expected sound by the UAV to generate a noise cancellation effect based in part on the identified sound propagation of the surrounding environment, each set of propellers of the one or more sets of propellers being of a different size from another set of propellers of the one or more sets of propellers. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15)

16. An unmanned aerial vehicle (UAV) comprising:
-
a frame; a first set of propellers of a first size associated with a propulsion system associated with the frame, the first set of propellers of the first size configured to provide propulsion for the UAV; a second set of propellers of a second size associated with the propulsion system associated with the frame, the second set of propellers of the second size being in a particular configuration with respect to the first set of propellers of the first size and further configured to provide thrust and directionality in a flight path for the UAV; and a computing system configured to manage the propulsion system during a flight associated with a delivery of a payload and further configured to instruct the UAV to; modulate the first set of propellers at a first rotational speed and the second set of propellers at a second rotational speed simultaneously during a flight corresponding to the flight plan so as to generate an expected sound that generates a noise cancellation effect. - View Dependent Claims (17, 18, 19, 20)
