SP-100 high-temperautre advanced radiator development

Under contract to NASA-Lewis Research Center, an advanced radiator concept design has been developed meeting SP-100 thermoelectric requirements. Carbon-carbon heat pipes are utilized to produce this lightweight, high performance radiator. Two fundamental feasibility issues had to be solved to enable the design: first, to produce a carbon-carbon heat pipe tube with integral fins, meeting both thermal and mechanical requirements; and second, to develop a coating that protects the carbon-carbon substrate from 875 K potassium working fluid
