A compound autogyro has a unique system of rotor blade retraction and vectored thrust. Redundant thrust systems provide for emergency conditions. Located in the upper mast are twin gas lines leading to a hub section of the rotor. In the hub, they divide the mass flow into two additional gas lines reaching to the tip ends of rigid rotor blades. A revolving, upper section of the rotor mast is attached to a lower, non-rotating section by a spherical bearing. Directly beneath this attach bearing is a distribution plenum, which receives the mass flow from each of three or four turbofan engines. To achieve high levels of propulsion, the turbofans are equipped with vectoring vanes that direct the mass flow to a plenum or, in the alternative, out a jet pipe for conventional flight. Another set of vectoring vanes can direct the mass flow downwardly, in case of a serious failure upon takeoff.
