The Effects of Propellant Leakage on the Heat Transfer to a Cryogenic Propellant Tank Utilizing High-Performance Multilayer Insulations
Long-term storage of cryogenic propellants in space requires an insulation system utilizing multiple radiation shields (multilayer insulations). The heat flow through this type of insulation is critically dependent upon the gas pressure within the insulation. Laboratory investigations indicate that gas pressures exceeding 10-5 torr can significantly increase the heat transfer through these insulations. Propellant leakage from a tank, if present in sufficient quantities, can increase the heat transfer through the insulation many times.
