ENVIRONMENTAL RESEARCH SATELLITES FOR SPACE PROPULSION SYSTEMS EXPERIMENTS.

Abstract

Progress is presented on the development, fabrication, test, and delivery of Environmental Research Satellites for in-space propulsion systems experiments. Two spacecraft will be built for the friction experiment and two spacecraft for the zero g heat transfer experiment. The first units of each experiment will be designated the prototypes. The flight units will be launched as subatellites from a primary launch mission. The friction experiment is concerned with the broadening of knowledge with surface friction in the space environment. The experiment can contribute to our understanding of surface friction processes in the bombined environment of space vacuum and radiation. The zero g heat transfer experiment is concerned with the influence of change of gravitational acceleration on heat transfer coefficients in the various transfer regimes and heating rates at which trnasitions between these regimes occur. The low g heat transfer data obtained may be applied in the design of systems involving heat transfer to volumes of fluid as typically occurs in tankage. This progress report covers the second quarter of the program. (Author)
