ABSTRACT:
A hand controller for a control system, such as a flight control system, includes a control grip and an support assembly for supporting an operator's forearm so that the operator's wrist joint and hand extend forwardly of the support assembly and the operator's hand is positioned to grip the control grip. The controller also includes roll, pitch and yaw gimbal components. The roll gimbal component is movable about a fore-and-aft extending roll axis defined along a base line of the operator's forearm. The pitch and yaw gimbal components are movable about respective side-to-side extending pitch and up-and-down extending yaw axes defined through the center of the operator's wrist joint in orthogonal relation to one another and to the roll axis. The roll, pitch and yaw gimbal components are coupled to one another and to the control grip in a given sequence for facilitating pivotal motion of the operator's hand about the roll, pitch and yaw axes to activate hand control functions with minimal forearm movement. Also, the controller includes a plurality of transducers for sensing movement of the roll, pitch and yaw gimbal components and generating control signals in response thereto.
