Superfluid experiment in the zero gravity state was performed with a cryostat aboard a sounding. rocket S-520. The observation of dynamic behavior of liquid helium (Hell), the verification test of a porous plug phase separator with a controling heater, the investigation of the heat transfer and the breakdown of superfluid thin film, and the noise test of a cooled FET pre-amplifier for IR detectors were performed. The experiment showed that the initial bulk fluid motions rather quickly damped and a stable liquid containment in the cryostat was realized, and that a very good temperature uniformity was attained throughout the vessel because all inside surfaces were covered with bulk Hell or thick adsorbed film. The porous-plug was found to work as good as the prediction in the zero-g state. The adsorbed film became thicker in the reduced gravity state than on the ground, but not so thick as the estimate given by the theory of van der Waals adsorption film. Basides these, this experiment added valuable data to practical applications of cryogenic technology to space.
