Abstract : The design, analysis, and fabrication is presented for a porous-tungsten transpiration cooled, test module. Specific accomplishments included the following: the design and analysis for the first throat module test was completed, including verification of the joining method selected, fabrication of the module components has been completed and final assembly has been initiated, simulated test runs using liquid NH3 have been made to verify cooling system operation, and bench tests to verify pressure shock loading, infiltrated graphite performance, hydrogen-tantalum reactivity, and cooling effectivity were completed.
