Two heat-pipe test articles were fabricated and tested, furthering the development of a refractory-composite/heatpipe-cooled leading edge. A 3-ft-long, molybdenum-rhenium heat pipe with lithium working uid was fabricated and tested in a vacuum chamber at an operating temperature of 2460 ± F, verifying the heat-pipe design. Following the fabrication of the initial heat pipe, three additional heat pipes were fabricated and embedded in carbon/carbon. The carbon/carbon heat-pipe test article was successfully tested using quartz lamps in a vacuum chamber in both horizontal and vertical orientations. Startup and steady-state data indicated similar operation in both orientations but different behavior among the three heat pipes. Radiography and eddy current evaluations were performed on the test article and indicated differing carbon/carbon thicknesses and a potential disbond.Nomenclature d = artery diameter, in. m = mass of lithium in heat pipe, lb P = pressure, psi q = heat ux, Btu/s q 00 = heat ux per area, Btu/ft 2 -s r = radius, in. T = temperature, ± F t = time, s V = voltage, V x = distance from end of carbon/carbon, in.
