Simulation Approach to Development of the XV-5A Lift-Fan V/STOL Aircraft

Design features of the XV-5A lift fan V/STOL airplane combine uniquely to give it the speed performance of a jet in conventional flight and the take-off and landing capability of a helicopter. The simulation program represents three main functions in the aircraft development cycle: mathematical models optimize the flight control system design; an actual control system replaces its mathematical counterpart; simulation enables the test pilot to become completely familiar with cockpit controls and handling. Flight simulation faithfully represents aircraft dynamics and presents a realistic visual display of position and motion of the aircraft with respect to the earth.
