Abstract: A propulsion system for an unmanned aerial vehicle (UAV) includes a propulsion motor configured to drive a propeller and an apparatus configured to releasably couple the propeller to the propulsion motor. The apparatus includes an engagement member, at least a portion of which is positioned to move relative to the propulsion motor and/or the propeller along a rotational axis of the propulsion motor between an engaged position and a disengaged position different from the engaged position. When in the disengaged position, the engagement member couples the propeller to the propulsion motor.
