Improved Reflector Assembly for AN/VSS-3 Searchlight.
Abstract
This report covers the activities undertaken and accomplished relative to the development of an improved reflector assembly for the AN/VSS-3 and AN/VSS-3A 1 Kilowatt, Xenon Short-Arc Searchlight Assembly. The work involved a number of interrelated activities. Initial operational and performance tests were accomplished, using a Government supplied AN/VSS-3A Searchlight Assembly, to verify that certain performance degradation, which had been noted in previous production contracts involving the Searchlight Assembly, was the result of instabilities of the reflector mount, or hub, or of a 'slippage' or movement of the electroformed reflector relative to the mount, or hub. Ray trace and re-image optical tests confirmed that such movement or 'slippage' was, in fact, occurring. A complete re-design of the reflector assembly was accomplished through sequential fabrication and test of modified versions of the components. Improved stability and gripping of the reflector was accomplished by a combination of changes including hub and retainer materials, quantity, size and torque requirements of the clamping bolts, the development of a lapping technique to improve the match of the hub and retainer to the reflector, together with other related improvements.
