Abstract

With the approach of complex space missions and long cruise times, a rapid cooldown of the cryogenic propellant line becomes mandatory. Some of the problems of long chilldown include propellant waste and delayed engine starting. Early liquidsolid contact during cooldown of engine suction lines is required to damp out liquid mass fluctuations to avoid flow instabilities and pump cavitation.
