This report presents the status of work performed on the High Temperature Turbine Technology Program, Phase II Technology Test and Support Studies during the Fourth Quarter of 1981, October 1-October 31, 1981 and summarizes the accomplishments of the previous three quarters of 1981. All components of the Turbine Spool Technology Rig (TSTR) were fabricated or reworked as necessary for assembly and test at 2600/sup 0/F turbine inlet temperature to evaluate the effect of hot gas stream particulates on the transpiration air-cooled turbine. Testing of the TSTR was completed with 102:15 h total time including 75:00 hours with particulate injection at 2600/sup 0/F turbine inlet temperature. Testing of the 60/sup 0/ sector combustor rig was completed in preparation for the TSTR test program. This preparatory testing included development of the particulate injection system and evaluation of other combustor modifications prior to incorporation of these changes into the TSTR combustor. The development status of both the low Btu gas fuel-cooled combustor and high temperature, low emissions coal-derived liquid-fueled combustor are reviewed. The low Btu gas fuel cooled combustor was assembld and successfully tested at atmospheric conditions. The high temperature, low emissions coal-derived liquid fueled combustor has been fabricated and is being assembled prior to test. Control systems status and descriptions for the above items are given. The analytical studies to support the TSTR and combustor programs are described. Extended time oxidation testing of Nichrome V-Cb material porous mesh for transpiration air-cooled turbine airfoils is continuing; test results to date confirm predictions that the effect of oxidation on cooling airflow capacity diminishes exponentially as exposure time increases.
