Avia tilting-rotor convertiplane

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