Abstract:

A preliminary design study for a composite research aircraft was conducted. The primary objectives were to define the optimum design and to prepare a program for the follow-on development of a VTOL rotary-wing composite research aircraft embodying the low disc loading and low-speed maneuverability of the helicopter and the high speed and liftdrag ratios of fixed-wing aircraft. The D266 Composite Research Aircraft design that resulted is based on the demonstrated and proved tilting-rotor concept. Design gross weight of the D266 is 23,000 pounds. Power is provided by two General Electric T64-GE-12 free-turbine engines. Design complexity is no greater than that of a twin- engine dual-rotor helicopter. All flight procedures are simple and straightforward and may be performed by one pilot. The cargo compartment, which exceeds the requirements, provides space for 24 troops.
