Long-term storage of cryogenic propellants on orbit as the replenishing fuel for spacecraft and energy supply source for space station is a crucial part of future space exploration. Thermodynamic vent system (TVS) was proposed as an effective technology to maintain the propellant tank pressure and reduce the mass loss of liquid propellant. This study presents an experimental investigation on the pressure...
A combination of polyurethane foam and multilayer insulation is adaptive and qualified for cryogenic propellant storage application, both on orbit for long-duration mission and on earth before and during launching. A generalized layer by layer model has been proposed to predict the thermal performance of the “Foam - Variable Density Multilayer Insulation combination” (FMLI) at different vacuum levels...
