Dieter Dölling,Christian Laue,Henning Sass. For a pump-fed engine, the pressure required is that necessary to suppress cavitation in the pump. This pressure is the difference between total head and vapor head at the pump inlet. Cryogenic propellants are characterized by large vapor-pressure variation with temperature, and the vapor pressure

ly induced axial stress will develop in the cable as it is cooled. The goal of the tests was to investigate the thermoelastic behavior of a 3.5-m section of a model of a SPTL cable constrained to constant length while the cable section was subjected to repeated thermal cycles between ambient and operating temperature.
