Suspension system for gimbal supported scanning payloads

摘要

Gimballed scanning devices are an important aspect of space science. To achieve a scan pattern some means must be provided which impart to the devices an oscillatory motion. Various forms of machines have been employed for controllably conferring scan patterns on these scanning devices. Although they have included control moment gyroscopes, reaction wheels, torque motors, reaction control systems, and the like, rotating unbalanced mass (RUM) devices are a new and more efficient way to generate scans in gimballed devices or payloads. But they require power consuming and frequently complex auxiliary control systems to position and reposition the particular scan pattern relative to a target or a number of targets. Herein the control system is simplified. In the suspension system provided for payloads rotatably supported in gimbals payload rotation is restricted by a flex pivot so that the payload oscillates, moving in a scan pattern.
