Abstract

Previous work at the NASA George C. Marshall Space Flight Center illustrated the cooling effect of bubbling helium gas through liquid oxygen, with subsequent application of this phenomenon in Saturn space vehicle oxidizer suction lines, which, due to the combined effect of length, diameter, and environmental heating during standby, became too hot for proper turbopump and rocket engine performance. Parallel interest in the use of helium gas injection to reduce the temperature of liquid hydrogen dictated the study reported here.
