초록

A method of stabilizing a jet-powered tri-mode aircraft as the aircraft travels in a helicopter mode, a compound mode, and a fixed-wing mode is disclosed. The method includes receiving a plurality of velocity vector component values and velocity vector commands derived from either (1) a number of pilot operated controllers or (2) a commanded array of waypoints, which are used for fully automated flights, and a rotor speed reference value, which is decreased with increasing forward speed to unload the rotor, thereby permitting conditions for stopping the ...

청구항

1. A jet-powered tri-mode aircraft capable of automatically transitioning from a helicopter mode to a compound mode to a fixed-wing mode without any intervention by a pilot of the aircraft, the aircraft comprising:a fuselage; a turbofan engine mounted within the fuselage for producing an exhaust gas flow; a rotor blade having a plurality of exit nozzles for outputting the gas flow, the rotor blade being mounted on the fuselage; a mast valve for regulating the gas flow to the plurality of exit nozzles of the rotor blade; a cruise nozzle for regulating and...
