Abstract:
The major engineering effort was directed toward completion of the permeation studies of sample materials, development of alternate barrier designs, and fabrication of converters for evaluation and life testing. The permeation of fossil fuel combustion gas was determined for alumina, beryllia, and silicon carbide samples, using a prototype burner designed for this purpose. Supplemental tests were run uwing helium, argon, and nitrogen on alumina and hydrogen on silicon carbide. Alumina appeared to be the best barrier material of those tested. Alternate barrier-emitter systems were designed, including multilayer-coated molybdenum cups and a double-walled alumina-molybdenum assembly with helium-filled interstice. A double-walled converter developed over eight watts on preliminary test. Author
