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 its ability to provide the gunners muscular efforts with a smooth controlled resistance. Such a resistance reduces the conflict between the gunners 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.
