VISCOUS-DAMPING MECHANISMS AS APPLIED TO FOUR INCH ROCKET LAUNCHER MOUNT

Abstract

Development is reported of a lightweight, variable, viscous-damping mechanism for a rocket launcher mount. This development is based on the Human Engineering Laboratories' recent demonstration of the advantages and torsional rate parameters that viscous damping offers in tracking moving targets with a 'free' mount. A 'free' mount is defined as one which a single man can move simultaneously in elevation and azimuth without using handwheels or mechanical power. The chief advantage of a damping mechanism lies in it's ability to provide the gunner's muscular efforts with a smooth controlled resistance. Such a resistance reduces the conflict between the gunner's muscular coordination and the inertial characteristics of the rotating launcher. The gunner is then much less likely to show high-frequency alternation between leading and following a moving target.
