Abstract: A propulsion system assembly includes a propeller, a motor configured to drive the propeller to rotate, and a locking mechanism configured to detachably lock the propeller to the motor. The propeller includes one of a first body and a second body. The motor includes another one of the first body and the second body. The locking mechanism includes a coupling member including a femoral position groove, a fastener configured to fix the coupling member to the second body, and a locking member configured to lock the first body to the coupling member and the second body. A bottom portion of the first body that contacts the coupling member includes a protruding rib configured to fit with the femoral position groove to restrain the first body from rotating relative to the coupling member.

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.

Abstract: A propulsion system assembly includes a propeller and a motor configured to drive the propeller to rotate. The propeller includes one of a first body and a second body. The motor comprises the other one of the first body and the second body. The propulsion system assembly also includes a locking mechanism configured to detachably connecting the first body and the second body. The locking mechanism includes a locking member and a position limiting lock catch. The locking member is configured to lock the first body and the second body. The locking member includes locking parts located at at least two sides of the locking member. When the locking parts of the locking member rotate to a locking position, the position limiting lock catch is mounted to a side of the locking parts, to restrain the locking member from rotating relative to the first body.
