Abstract:
Several components for the X-20 Dyna-Soar thermal management system were in final fabrication when the original Dyna-Soar contract was cancelled. The components for three systems were refurbished and, where necessary, remanufactured and then assembled, and acceptance tested. The thermal management system is designed to remove heat from several heat-generating sources on the X-20 space Vehicle, and to return a portion of the heat to the hydrogen storage tank to maintain tank pressure. The system employs an aqueous ethylene glycol heat-transport fluid to connect the various heat sources to the heat sink. The heat sink is cryogenic hydrogen, which is stored in the supercritical state as fuel for the auxiliary power unit APU. The distinguishing feature of this system is its ability to proportion, as required, the total hydrogen flow to the APU and the cooling load, while maintaining system stability and logic over tank pressurization, heat rejection, and APU fuel demand.
