Dynasim: A Spatial Disorientation Tool.
Abstract
The Dynasim can be used for research on the important problem of pilot disorientation. The facility consists of three main components: a motion system visual surround for presentation of Earth-fixed or moving targets, and a computer control system. The motion system is a short-arm centrifuge that provides yaw-axis rotation (at a maximum angular velocity of +/- 150 deg/s and angular acceleration of +/- 15 deg/s2) of an off-center cockpit housed in an aircraft-like fuselage that moves about its own pitch and roll axes. The pitch and roll axes of the fuselage are closed-loop position feedback systems that can be controlled manually or by computer through +/- 30 deg. The fuselage can be oriented manually in four different headings: 0, 90, 180, and 270 deg relative to the center of rotation. The pitch and roll axes can be operated in a mode where the cockpit is kept aligned with the resultant linear acceleration vector for an angular range of 0-15 deg corresponding to an angular velocity of 0-90 deg/s. The computer system can present a variety of visual displays on two CRT scopes in the cockpit instrument panel. A Malcolm Horizon installed inside the cockpit displaying across the face of the panel can be used by the 'pilot' to fly by instruments and counteract computer control of the motion device Naval aviation, Spatial disorientation, Pilot vertigo, Acceleration, Motion Device, Vestibular
