The present invention provides a tilt rotor aircraft having a centrally
mounted tiltable engine and rotor assembly. A turbine or other type of
engine (or engines) is pivotally mounted on a central frame above and
between the pilot and co-pilot, who occupy separate and identical control
cockpit pods on either side of the engine. Placing the engine between the
pilot and copilot maintains the CG within a narrow band in both
horizontal and vertical flight modes, simplifying control and handling.
Counter-rotating propellers may be driven by the engine(s) to eliminate
torque effects. By mounting the engine and rotor package between and
above the pilot and copilot, the rotor can be made to clear the ground,
allowing the aircraft to land like an ordinary fixed-wing aircraft
without damaging the propellers. Thus, the craft can be launched and
landed in VTOL, HTOL, or STOL configurations, depending upon conditions
and available landing and takeoff sites.
