ANALYSIS OF LIQUID-HYDROGEN STORAGE PROBLEMS FOR UNMANNED NUCLEAR-POWERED MARS VEHICLES
Abstract
Tankage, nuclear shielding, and hydrogen heatinput problems are investigated for three unmanned nuclear vehicles intended for probing in the vicinity of Mars and landing freight on Mars. Tank geometry, tank and supporting-structure weight, and tank protection from meteoroids are discussed. The size and weight of the nuclear shield as required by a prescribed allowable dose and/or the heat input to the hydrogen are determined. The hydrogen heat input includes nuclear, onboard thermal, solar, and planetary sources. (Author)
