Pagination or Media Count:
Pertinent fixed-and rotary-wing feasibility studies and handling- qualities research programs are reviewed and the effects of certain controller characteristics on handling qualities for specific rotorcraft flight tasks are summarized. In particular, the effects of the controller force-deflection relationship and the number of controlled axes that are integrated in a single controller are examined. Simulation studies conducted as part of the Armys Advanced DigitalOptical Control Systems ADOCS program and flight research programs performed by the National Aeronautical Establishment of Canada provide a significant part of the available handling qualities data. These studies demonstrate the feasibility of using a single, properly designed, limited- displacement, multi-axis controller for certain relatively routine flight tasks in a two-crew rotorcraft with nominal levels of stability and control augmentation with a high degree of reliability are incorporated, separated three- or two-axis controller configurations are required for acceptable handling qualities.
