A 10,000 hour life multipropellant engine for Space Station applications

Performance characterizations of an engineering model multipropellant resistojet

“…Among the most significant improvements relative to the design detailed in Ref. 3 are associated with assembly procedures, a redesigned radiation shield pack, a modified electron beam weld procedure, and minor material specifications. This fifth iteration represents the culmination of all efforts expended toward development of the engineering model multipropellant resistojet and will carry forward as the starting point for prototype development.…”

Electric propulsion for International Space Station reboost - A fresh look

“…2 In the current ISS infrastructure water is not considered available for propulsion. Only CO 2 was considered in this study for a resistojet.…”

“…Drag force = -1/2 * Density * Drag Coefficient * Area * Satellite Velocity 2 The ISS velocity is dependent upon the assumed circular altitude. As with the JSC analysis, the ISS orbit is assumed (and calculated) to be circular.…”

“…1,2,3,4 These past studies mainly focussed on using space station waste gases as propellants in order to reduce the amount of reboost fuel needed to offset atmospheric drag and keep the station in its proper orbit. Results of these studies showed large savings in terms of launched chemical reboost fuel.…”
