Paper Abstract

The concept, design and analysis of a unique, thermal diffusion demonstration experiment (Chuck) is described. Chuck flew as the science payload of an active vibration isolation system called STABLE on STS-73 in October 1995. The experiment was designed to contribute to materials science studies, besides other disciplines, by providing quantitative data (through optical interferometry) on heat transfer in a fluid subjected to varying levels of vibration in a low-gravity environment. It employed very simple geometry, in a well understood circumstance, to allow materials science investigators to verify analytical and numerical models currently utilized for design and theoretical studies in a wide range of experiments. Its design, build, testing and integration was achieved in a record five months duration using essentially off the shelf components and minimal costs.
