Abstract: Systems and methods to improve stability and control of an aerial vehicle are described. For an aerial vehicle having a ring wing around a fuselage and a plurality of propulsion mechanisms, one or more sections of the ring wing may be pivotable to reduce vibrations and forces transferred to the aerial vehicle, and to prevent stall and minimize turbulence experienced by the aerial vehicle. The pivotable sections of the ring wing may be freely pivotable, may include locking elements to prevent or allow pivoting, may include bias elements or dampening elements to partially control the free pivoting, or may include actuators to effect desired pivoting.

Abstract: Various reconfigurations of propulsion mechanisms of an aerial vehicle are described. For example, responsive to a fault or failure of a propulsion mechanism, the remaining propulsion mechanisms may be modified to maintain control and safety of the aerial vehicle. In example embodiments, cant angles, toe angles, positions, and/or orientations of one or more propulsion mechanisms may be modified to maintain control and safety in either a horizontal, wingborn flight orientation, or a vertical, VTOL flight orientation.

Abstract: Various reconfigurations of propellers, propeller blades, and/or blade sections of propulsion mechanisms of an aerial vehicle are described. For example, responsive to a fault or failure of a propulsion mechanism, propellers, propeller blades, and/or blade sections of the remaining propulsion mechanisms may be modified to maintain control and safety of the aerial vehicle. In example embodiments, angular orientations, positions, and/or lengths of one or more propellers, propeller blades, and/or blade sections of propulsion mechanisms may be modified to maintain control and safety in either a horizontal, wingborn flight orientation, or a vertical, VTOL flight orientation.
