Conceptual Design Study of 1985 Commercial Tilt Rotor Transports: VTOL design summary, Volume 1National Aeronautics and Space Administration, 1975 - 102 pages Aircraft were synthesized in the 21-, 45-, and 100- passenger categories. Technological factors were considered and the 45-passenger point design, designated the D312, was selected. Variants of the D312 having sideline noise levels in hover of + or - 5 PNdB were also studied. All three 45-passenger aircraft were analyzed for performance, weights, economics, handling qualities, noise footprints, aeroelastic stability and ride comfort. Results are presented. |
