Abstract : This final report summarizes the work performed by Lockheed Missiles and Space Company, Inc. (LMSC), under SDIO Contract number SDIO84-89-C-0028, Tribomaterials/ Precision Gimbal Demonstration (T/PGD) program. The overall T/PGD goal is to demonstrate enhanced performance and life of Strategic Defense Initiative (SDI) vehicle systems via insertion of advanced tribomaterials into precision gimbal bearing assemblies. This is in recognition of the critical importance that bearings and lubricants have on the mission performance, reliability and survivability of SDI precision gimbals. In particular, tribomaterial advancements were needed to meet the stringent life and jitter requirements of SDIO gimbaled sensors, fine pointing antennas, CMG gimbals and other tribomechanisms. LMSC T/PGD Program Plan is illustrated in Fig. 1-1. The program was structured into two phases plus an optional third phase. The 4-month Phase I conceptual design study was completed in October 1989. Current SDI tribomaterial limitations were identified, the performance of promising new solid and liquid lubricants were characterized, and their potential benefits to SDI gimbals were highlighted. This work was reported in the Phase I Final Report. jg p.7
