    Abstract: An aerial vehicle is provided which includes first thrusters with first propellers and second thrusters with second propellers. Each of the first propellers has a first rotating region in which blades thereof rotate. Similarly, each of the second propellers has a second rotating region in which blades thereof rotate. Each of the first rotating regions is located to overlap one of the second rotating regions, as viewed in a direction of a yaw axis of the aerial vehicle. The first rotating regions are located away from the second rotating regions in the direction of the yaw axis. Such layout of the first and second propellers eliminates physical interference therebetween. The overlap between the first and second propellers results in a decreased cross-sectional area of projection of the aerial vehicle from the front view in a flight direction thereof.

    Abstract: 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 of one or more propeller blade treatments of a propeller blade of an aerial vehicle during operation of the aerial vehicle. For example, the propeller blade may have one or more propeller blade treatments that may be adjusted between two or more positions. Based on the position of the propeller blade treatments, the airflow over the propeller is altered, thereby altering the sound generated by the propeller when rotating. By altering the propeller blade treatments on multiple propeller blades of the aerial vehicle, the different sounds generated by the different propeller blades may effectively cancel, reduce, and/or otherwise alter the total sound generated by the aerial vehicle.
