Abstract
Use of uncoupled, six-degree-of-freedom (6-DOF) motion is rapidly becoming state-of-the-art in terms of necessary flight control laws and aerodynamic capability. The next generation of aircraft may use uncoupled, 6-DOF control capability in conjunction with other new technologies. In order for future applications of 6-DOF control to be successful, the pilot must be able to command motion and acceleration magnitudes with sufficiently good system response characteristics to accomplish particular missions or tasks. This study sought to develop design criteria and gather appropriate substantiating data for cockpit control devices for 6-DOF motion which will assure compatibility among the pilot, control device(s) and aircraft response and thus allow efficient implementation of the 6-DOF control capability. Phase I consisted of defining existing data on the design of cockpit controllers for 6-DOF motion. Application of 6-DOF aircraft motion to aircraft mission requirements was examined. A set of tentative criteria was formulated and test plans developed to gather data necessary to validate and expand the tentative criteria. A simulation was conducted using the motion based simulator at Wright-Patterson AFB. Results of the simulation were combined with the results of the literature survey to form a set of design guidelines. Volume I presents the results of the literature survey, summarizes the simulation effort and presents the design criteria. Keywords: Flight control; Flying qualities; Man machine relations; Pilot-vehicle interface; and MIL-F8785.
