Abstract: This disclosure is directed to a single blade propeller and systems, devices, and techniques pertaining to assisting in critical stages of flight (e.g., takeoff, landing, emergency situations, etc.) in vertical takeoff and landing (VTOL) aircraft. The single blade propeller may be incorporated into fixed and rotary wing VTOL aircraft as part of a first propulsion system. The first propulsion system may include one or more single blade propellers driven by electric motors, combustion engines, and/or hybrid engines. Each of the single blade propellers may include a lift-producing blade and a counterweight opposite the lift-producing blade. As each of the single blade propellers spins, it may produce lift in a direction approximately perpendicular to the horizon to effect vertical flight.
Abstract translation: 本公开涉及一种涉及在垂直起飞和着陆（VTOL）飞机中辅助关键飞行阶段（例如起飞，着陆，紧急情况等）的单个桨叶螺旋桨和系统，装置和技术。 作为第一推进系统的一部分，单桨螺旋桨可以并入固定和旋转翼型垂直起降飞机中。 第一推进系统可以包括由电动机，燃烧发动机和/或混合发动机驱动的一个或多个单个叶片螺旋桨。 单个叶片螺旋桨中的每一个可以包括提升产生叶片和与提升产生叶片相对的配重。 当每个单刀片螺旋桨旋转时，它可能在大致垂直于地平线的方向上产生升力以实现垂直飞行。

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 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.

Abstract: Aerial vehicles may include propulsion units having motors with drive shafts that may be aligned at a variety of orientations, propellers with variable pitch blades, and common operators for aligning the drive shafts at one or more orientations and for varying the pitch angles of the blades. The common operators may include plate elements to which a propeller hub is rotatably joined, and which may be supported by one or more linear actuators that may extend or retract to vary both the orientations of the drive shafts and the pitch angles of the blades. Operating the motors and propellers at varying speeds, gimbal angles or pitch angles enables the motors to generate forces in any number of directions and at any magnitudes. Attributes of the propulsion units may be selected in order to shape or control the noise generated thereby.

Abstract: Systems and methods to form distributed and reconfigurable aerial vehicle configurations are described. An aerial vehicle configuration may include a plurality of aerial vehicles that are connected to a payload via respective tethers in order to complete a task, e.g., delivery of the payload to a location. The plurality of aerial vehicles selected as part of the aerial vehicle configuration may be of various types and may form a particular initial configuration. During operation, the aerial vehicle configuration may be modified based on changes to various operating parameters associated with aerial vehicles, the aerial vehicle configuration, the task, and/or the environment. The modifications may include changing positions, altitudes, and/or orientations of aerial vehicles with respect to each other and/or the payload, releasing aerial vehicles from the configuration, or adding new aerial vehicles to the configuration.

Abstract: Described is an aerial vehicle, such as an unmanned aerial vehicle (“UAV”), that includes a plurality of sensors, such as stereo cameras, mounted along a perimeter frame of the aerial vehicle and arranged to generate a scene that surrounds the aerial vehicle. The sensors may be mounted in or on winglets of the perimeter frame. Each of the plurality of sensors has a field of view and the plurality of optical sensors are arranged and/or oriented such that their fields of view overlap with one another throughout a continuous space that surrounds the perimeter frame. The fields of view may also include a portion of the perimeter frame or space that is adjacent to the perimeter frame.

Abstract: Described is an apparatus and method of an aerial vehicle, such as an unmanned aerial vehicle (“UAV”) that can operate in either a vertical takeoff and landing (VTOL) orientation or a horizontal flight orientation. The aerial vehicle includes a plurality of propulsion mechanisms that enable the aerial vehicle to move in any of the six degrees of freedom (surge, sway, heave, pitch, yaw, and roll) when in the VTOL orientation. The aerial vehicle also includes a ring wing that surrounds the propulsion mechanisms and provides lift to the aerial vehicle when the aerial vehicle is operating in the horizontal flight orientation.
