Flying Qualities Development and Flight Simulation Evaluation of the TW-68 Tilt-Wing VTOL Aircraft 932517
The TW-68 is a civil tilt-wing aircraft proposed by the Ishida Group. Flight simulation was applied to develop the flying qualities of this design. The simulation was accomplished using a mathematical model specially created for this purpose. The effort culminated in piloted evaluations of the simulated aircraft's flight characteristics in a variety of representative mission tasks, both with and without the augmentation of a core Automatic Flight Control System. The paper describes the mathematical model, simulation experiments and results. Flight control laws and their development are also discussed, as are the predicted flight capabilities and limitations of the TW-68.
