摘要：

Selected results are presented from a two-phased experimental program to investigate powered-lift aircraft handling quality degradation due to both naturally-occurring and computer-generated atmospheric turbulence. In phase I a variable stability helicopter was flown to simulate a powered-lift aircraft on final approach. In phase II a ground-based simulator with a moving cockpit and a colored visual display was used to represent the same powered-lift aircraft. During phase II a Dryden model of atmospheric turbulence was used together with actual wind profiles recorded during phase I. This paper focuses on the phase II results, which demonstrate that the Dryden model can yield optimistic ratings of airplane handling qualities in turbulent landing conditions. The model also leads to an optimistic estimate of combined pilot-vehicle performance degradation in turbulent flight. © 1979 American Institute of Aeronautics and Astronautics, Inc., All rights reserved.
