The Mono Tiltrotor (MTR) is a proposed, innovative heavy-lift rotorcraft architecture. The emerging military strategies most suited to potential application of the MTR are Navy Sea Basing with Ship to Objective Maneuver, and Army Future Combat Systems with mounted maneuver and air mobility. The present work reports on a conceptual design study that has been conducted to predict the sizes and weights of the MTR architecture and to objectively examine its potential performance. A detailed weight budget has been determined based on historical component data for helicopters and airplanes. A thorough component drag breakdown has allowed for good estimates of the overall lift-to-drag ratio of the MTR concept in both the helicopter mode and airplane cruise conditions. A requirement was that the machine carry its payload over an unprecedented unrefueled distance of 1,000 nautical miles. It is shown that if technically realizable, the MTR architecture allows for a relatively compact and lightweight rotor design, with an accompanying lightweight airframe and relatively low fuel load compared to competing helicopter concepts.
