ABSTRACT:
A compact, cascaded three degrees of freedom (DOF) motion system for providing roll, pitch and heave movement to a cockpit of a flight simulator. The cockpit is nested within a rotatable roll frame which is gimbaled within a pitch frame. The pitch frame is pivotally connected at its rear to a vertically disposed and translatable heave frame. A pair of heavy, torsionally rigid, horizontally disposed, torque tubes in a four-bar parallelogram linkage arrangement serve to connect the heave frame to a fixed base frame and to ensure parallel movement of said heave frame. Servo actuators connected to each of the roll, pitch and heave frames permit simultaneous, independent three-axis motion. Balance actuators, frame locking mechanisms, as well as other safety features, ensure failsafe operation of the improved motion system.
