ZBO Cryogenic Propellant Storage Applied to a Mars Sample Return Mission Concept

摘要

Zero Boil-Off (ZBO) Cryogenic Propellant Systems were designed and analyzed for a Mars sample return mission. JPL designed the spacecraft, and NASA GRC/ARC and contractors designed the cryogenic storage systems. The performance of those systems are compared to traditional storable propellant propulsion systems. The cryogenic storage system modeling included cryocoolers, heat pipes, a radiator, shadowing, MLI, foam, and tank internal components. Model descriptions and tools developed are shown, along with the systems performances and masses. Models show that the ZBO systems applied to cryogenic propellants are beneficial to the Mars mission.
