Conceptual design studies of a Mono Tiltrotor

The Mono Tiltrotor (MTR) has been proposed by the Baldwin Technology Company as an innovative VTOL concept that integrates a tilting coaxial rotor, an aerodynamically deployed folding wing, and an efficient cargo handling system. The MTR has been targeted to meet heavy-lift, long-range mission objectives for which there is growing demand from military planners. This thesis describes a series of conceptual design studies aimed at determining the potential value that the MTR concept would possess, if it were to be technically realized. A versatile rotorcraft sizing analysis was developed to perform sizing and weight predictions for conventional single rotor and coaxial helicopters, as well as the MTR concept, based on key input mission and design requirements. This analysis was partly based on historical trends used in the rotorcraft and fixed-wing aircraft industries. These methods were expanded upon to include the capability for sizing the unique MTR concept. (Abstract shortened by UMI.)...
