    Abstract: Systems and methods to reduce aerodynamic drag and/or affect flight characteristics of an aerial vehicle may include adjustable fairings associated with one or more components of the aerial vehicle. The adjustable fairings may be coupled to and at least partially surround a motor, propulsion mechanism, motor arm, strut, or other component of an aerial vehicle. In addition, the adjustable fairings may be passively movable between two or more positions responsive to airflow around the fairings, and/or the adjustable fairings may be actively moved between two more positions to affect flight characteristics. Further, the adjustable fairings may include actuatable elements to alter a portion of an outer surface of the fairings to thereby affect flight characteristics. In this manner, adjustable fairings associated with various components of an aerial vehicle may reduce aerodynamic drag and/or may improve control and safety of an aerial vehicle.

    Abstract: Affected areas of images captured by cameras that are experiencing one or more anomalies may be modified by inpainting portions of counterpart images onto the affected areas. Where a camera provided aboard an operating vehicle (e.g., an aerial vehicle) is experiencing an anomaly that adversely affects the quality of images captured thereby, counterpart images that are captured by other cameras (e.g., cameras provided aboard the vehicle or elsewhere) at the same time, or by the affected camera at an earlier time, may be used for inpainting. Portions of counterpart images may be selected for inpainting according to a transform function that takes into account a pose of an affected camera, dynamics of an operating vehicle or any other factors. Images that have been modified by inpainting may be utilized by an operating vehicle for any purpose, such as computer vision applications, navigation, guidance, or collision avoidance.

    Abstract: Disclosed are systems and methods for in-transit or in-flight error correction in state prediction of the vehicle. Natural patterns, such as fields, residential neighborhoods, business areas (e.g., downtown), etc., and/or objects, such as streets, cars, houses, trees, buildings, bridges, roads, parking lots, etc., that are naturally within the environment may be determined and used to correct any error in the aerial vehicle state prediction, while the vehicle is in transit, thereby eliminating or reducing the cumulative error involved in traditional systems.

    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: 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.
