In-Space Friction Tests.

Abstract

An investigation of boundary layer sliding friction of materials is presented. The program included the development of a satellite system and experiments to perform direct in-space measurements of sliding friction between sixteen material combinations. A fourteen month orbital test phase was accomplished. Using identical experiment hardware, ground test vacuum studies of sliding friction were also performed. These included both prelaunch tests, and post launch studies in which there were deliberate modifications of the laboratory vacuum environment. The information obtained in this program provides a basis for establishing the adequacy of simulation test criteria pertinent to both materials as well as component friction testing. (Author)
