High Viscosity Thermal Protection Materials. (2005)
Wilson, Roger E., Koubek, F. J.
Initial objectives of this work were to develop a high temperature resistant material capable of withstanding rocket nozzle throat, leading edge, or re-entry environments by virtue of its high...
Salt Water Resistance of Surface-Compression Strengthened Glass, (2005)
Wilson,Roger E., Perry,H. A., Koubek,F. J.
Three types of ion-exchange surface-compression strengthened (SCS) glass, with ultimate flexural strengths of 38,000 to 66,800 psi, were abraded and maintained in circulating salt water for periods...
CERAMIC-PLASTIC COMPOSITES FOR RAIN EROSION RESISTANT RADOMES. (1998)
Various ceramic materials in thin sheet form for use in covering critical areas of glass fiber reinforced plastic radomes were evaluated in rain erosion resistance. Of the ceramic materials tested,...
HIGH VISCOSITY THERMAL PROTECTION MATERIALS. (1998)
Processes were developed for hot pressing a 68.5% tungsten-31.5% silica composition to over 97% of the calculated theoretical density. Hot pressing characteristics changed when crystalline silica was...
HIGH VISCOSITY THERMAL PROTECTION MATERIALS. (1998)
A description is given of materials preparation and hot pressing of H-O rocket motor test nozzles of a 31.5% silica-68.5% tungsten composition. It also includes the H-O motor testing of nozzles of...
High Viscosity Thermal Protection Materials. (1998)
Vacuum hot pressing of scaled-up rocket nozzles and leading edge specimens of the tungsten-silica composition encountered devitrification problems. Rates between 4 and 16C per minute were found most...
High Viscosity Thermal Protection Materials Summary Report: 1 July 1969-30 June 1970, (1998)
Vacuum hot pressed nozzles of 20 v/o tungsten-80 v/o silica tested in the NOL oxy-hydrogen (H-O) rocket test motor out-performed the best of several ATJ graphite nozzles with a three fold increase in...
