    摘要: Disclosed is an electrically powered, reaction-drive type rotorcraft. Thrust generators on the outer portion of each rotor blade cause the rotors to spin and generate lift, and additionally, may be controlled to produce variable amounts of thrust as the rotor blades rotate through different sectors around a generally non-rotating fuselage such that net lateral forces are produced to control the position and velocity of the vehicle. The rotorcraft may also employ aerodynamic surfaces on each rotor blade whose parts or entire structure can be moved to produce net lateral and vertical forces for control of position and velocity of the vehicle. The rotorcraft, which may be operationally carbon-neutral, stores its electrical energy in batteries and other optional energy storage methods, and may harvest solar energy using arrays of photovoltaic cells disposed on its upper surfaces. Vehicle sizes may range from small Uncrewed Air vehicle Systems to large crewed aircraft.

    摘要: 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.
