Abstract : Ide tifiers: overing, VTOL Craft Bell D-2064, VTOL Craft Bell D -<%<.A simulator study was made of the longitudinal control and flight handling characteristics of three types of V/STOL aircraft during the transitional phase of flight bet een hover and co ventional l vel flight. The aircraft configur tions studied were in the 35,000 pound weight class and of the follo ing types: (1) dual tandem ducte propeller, ( ) ilt rotor, and (3) tilt wing with deflec d slipstream. Flight evalu tion of con rol power an damping were con uc ed to determine pilot rating boundaries for eac configuration. Other aerodynamic an control parameters investigated were: (1) speed stability parameter, (2) sta ic abili y param ter, (3) change in pitching moment due to ch nge in thru t, (4) CONVERSION RATE, (5) throttle gradient and (6) slope of the power re uired curve.
