DEVELOPMENT OF A SUSTAINABLE-G DYNAMIC FLIGHT SIMULATOR*

This paper discusses two related design issues that are critical to the development of dynamic flight simulation (DFS) capability using a man-rated centrifuge: 1) response time of the centrifuge in an operator-controlled simulation of a high performance aircraft and 2) the effect on an occupant of angular acceleration artifacts produced by a centrifuge that provides rapid response. The ability of a centrifuge operated in the DFS mode to meet the response recommendations of the Federal Aviation Administration (FAA) for motion simulators is discussed and a model-based controller is shown to improve the response capability of some existing centrifuges sufficient to meet the FAA recommendations. Human response tests have been conducted on the centrifuge at Wright Patterson AFB to evaluate sensitivity to the artifacts produced by a centrifuge. Results indicate the effect to be no more than a mild disturbance over the expected range of g-loading and artifact magnitudes. The unique feature of this type of motion simulator is that the pilot can be exposed 'This paper is declared a work of the U.S. Government and is not subject to copyright protection in the United States. t Associate Professor of Aerospace and Systems Engineering, Member I Professor and Head, Department of Aeronautics and Astronautics, Member to high-fidelity , sustained, elevated g-levels while receiving training in flight procedures and air combat tactics. The expected payoff for DFS-based training is reduced loss of life and equipment while becoming more proficient at practicing the most demanding maneuvers under g-stress.
