Abstract

This disclosure describes example reconfigurable propulsion mechanisms, example multi-rotor aerial vehicle apparatuses, and methods that may be used to alter the yaw torque polarity produced by one or more propulsion mechanisms in response to a detected loss of thrust produced by another propulsion mechanism of the aerial vehicle. For example, each reconfigurable propulsion mechanism may be configured to move between a normal operating position and a reconfigured operating position. When a reconfigurable propulsion mechanism is in a normal operating position, the yaw torque has a first polarity, such as clockwise. In comparison, when the same reconfigurable propulsion mechanism is in the reconfigured operating position, the yaw torque polarity produced by the propulsion mechanism is reversed and has a second polarity, such as counter-clockwise. Reconfiguration may be done to recover an aerial vehicle from a degraded operational state, for example resulting from a motor-out event, to a non-degraded operational state.
