Mechanical Function.
UUT Mount Assembly.
The UUT mount assembly consists of a platform that is movable in
azimuth and in elevation. Angular limits of travel are 4 degrees in
both planes.
Azimuth movement is accomplished with a platform that is pivoted
about a point located near the front of the mount.
The rear of the
platform rides on a rubber-ringed wheel that is rotated by turning
the azimuth adjustment control.
Elevation movement is accomplished with a platform that is hinged and
pivoted at its front edge.
As the elevation adjustment control is
rotated, a wedge moves forward or backward against a cam that is
attached to the platform.
Movement of the wedge against the cam
causes the platform to move about its pivot point.
Stablization of the UUT mount assembly is provided by a brace that
folds out from the base plate.
