An aerial vehicle may be equipped with propellers having reconfigurable geometries. Such propellers may have blade tips or other features that may be adjusted or reconfigured while the aerial vehicle is operating, on any basis. Propellers having reconfigurable blade tips joined to blade roots may cause the blade tips to be aligned with the blade roots, or substantially perpendicular to the blade roots, e.g., in order to counter adverse effects of tip vortices, or at any intervening angle. The propellers may be reconfigured at predetermined times during o...


1. An unmanned aerial vehicle (UAV) propulsion system comprising: a first motor mounted to a UAV;a first propeller comprising a first blade root, a first blade tip, and a first hub, wherein the first blade root has a first proximal end mounted to the first hub and a first distal end pivotably joined to the first blade tip by a first hinge,wherein the first motor is rotatably coupled to the first hub, andwherein the first motor is configured to rotate the first propeller through a plurality of angular orientations about a first axis; andat least one compu...
