摘要： Sounds are generated by an aerial vehicle (101) during operation. For example, the motors and propellers (102) of an aerial vehicle (101) generate sounds during operation. Disclosed are systems, methods, and apparatus for actively adjusting the position of one or more propeller blade treatments (202) of a propeller blade (200) of an aerial vehicle (101) during operation of the aerial vehicle (101). For example, the propeller blade (200) may have one or more propeller blade treatments (202) that may be adjusted between two or more positions. Based on the position of the propeller blade treatments (202), the airflow over the propeller (102) is altered, thereby altering the sound generated by the propeller (102) when rotating. By altering the propeller blade treatments (202) on multiple propeller blades (200) of the aerial vehicle (101), the different sounds generated by the different propeller blades (200) may effectively cancel, reduce, and/or otherwise alter the total sound generated by the aerial vehicle (101).

摘要： Sounds are generated by an aerial vehicle during operation. For example, the motors and propellers of an aerial vehicle generate sounds during operation. Disclosed are systems, methods, and apparatus for actively adjusting the position and/or configuration of one or more propeller blades of a propulsion mechanism to generate different sounds and/or lifting forces from the propulsion mechanism. A propulsion apparatus, comprising a motor (206), a propeller having a propeller blade (204) and a propeller adjustment controller configured to enable movement of the propeller such that the propeller blade (204) is extendable away from the motor (206) or retractable toward the motor (206). A method for adjusting a propulsion mechanism, comprising: determining a lifting force to be generated by the propulsion mechanism; determining a sound limit to be produced by the propulsion mechanism; selecting a combination of a revolutions per minute ("RPM") of a motor of the propulsion mechanism, a first position of a first propeller of the propulsion mechanism that will generate a first lifting force when rotated by the motor at the RPM, a second position of a second propeller of the propulsion mechanism that will generate a second lifting force when rotated by the motor at the RPM and a third position of a third propeller of the propulsion mechanism that will generate a third lifting force when rotated by the motor at the RPM such that a combination of the first lifting force, the second lifting force, and the third lifting force will generate the lifting force and produce a sound below the sound limit; causing, while the motor is rotating: the first propeller to move to the first position; the second propeller to move to the second position; and the third propeller to move to the third position.
