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.

Abstract: Aerial vehicles may be operated with discrete sets of propellers, which may be selected for a specific purpose or on a specific basis. The discrete sets of propellers may be operated separately or in tandem with one another, and at varying power levels. For example, a set of propellers may be selected to optimize the thrust, lift, maneuverability or efficiency of an aerial vehicle based on a position or other operational characteristic of the aerial vehicle, or an environmental condition encountered by the aerial vehicle. At least one of the propellers may be statically or dynamically imbalanced, such that the propeller emits a predetermined sound during operation. A balanced propeller may be specifically modified to cause the aerial vehicle to emit the predetermined sound by changing one or more parameters of the balanced propeller and causing the balanced propeller to be statically or dynamically imbalanced.

Abstract: A magnetic propeller device for an unmanned aerial vehicle (UAV) includes a propeller and a shaft mount that engage with a motor shaft of a UAV. The propeller and shaft mount each have a magnetic element. When both magnetic elements are aligned, the propeller engages the shaft mount by way of a magnetic holding force between the magnetic elements. When a propeller contacts an object and the propeller is displaced, the magnetic elements passively disengage the propeller from the shaft mount due to misalignment of the magnetic elements. Passive disengagement allows the propeller to rotate independently of the motor shaft. Once the UAV moves clear of the object, the magnetic elements can realign, such that the propeller re-engages the shaft mount and resumes rotation with the motor shaft.

Abstract: A device receives a request for a mission that includes traversal of a flight path from one or more first locations to a second location and performance of mission operations, and determines required capabilities and constraints for the mission based on the request. The device identifies UAVs based on the required capabilities and the constraints, and calculates a cost effective mission plan, for the identified UAVs, based on the required capabilities and the constraints. The device generates mission plan instructions, for the cost effective mission plan, that include flight path instructions for the flight path and mission instructions for the mission operations. The device provides the mission plan instructions to the identified UAVs to permit the identified UAVs to travel from the one or more first locations to the second location, via the flight path, and to perform the mission operations.

Abstract: A multiple rotors aircraft and a control method thereof are provided. The control method comprises the following steps. First, current motion information of the multiple rotors aircraft is obtained. Then, at least one control gain is adjusted through a gain adjustment function according to the current motion information. The gain adjustment function conforms to a non-Lipschitzian characteristic, and at least one rotor of the multiple rotors aircraft is controlled according to the control gain. Therefore, the multiple rotors aircraft would be ensured that its flight attitude is toward a target position, and the expected result would be conformed rapidly.

Abstract: The present invention is to prevent an uninhabited airborne vehicle from crashing due to fall impact and from being damaged and to protect an object and a living being at the fall point. The uninhabited airborne vehicle 100 includes a rotary wing 10 and a buffer 111 that reduces impact on the airframe when crashed. The battery charge remaining measurement module 122 and the distance measurement module 123 measure the battery charge remaining and the distance to an object, respectively, and compare the measurement with the respective thresholds. If the measurement is less than the respective thresholds, the buffer module 111 is driven by the drive module 121.
