Title: AUTOMATICALLY AND RELEASABLY COUPLING UAV PROPELLERS TO PROPULSION MOTORS, AND ASSOCIATED SYSTEMS AND METHODS
Abstract:
A propulsion system includes a propulsion motor (121) configured to drive a propeller (122) and an apparatus (203) for releasably coupling the propeller (122) to the propulsion motor (121). The apparatus (203) includes an engagement member (301). At least a portion of the engagement member (301) can be positioned to move relative to the propulsion motor (121) and the propeller (122) along a rotational axis of the propulsion motor (121) between an engaged position in which the engagement member (301) couples the propeller (122) to the propulsion motor (121) and a disengaged position different from the engaged position. An unmanned aerial vehicle, a propeller for an unmanned aerial vehicle, and associated systems and methods are also provided.
