Actions for High temperature gas turbine engine component materials testing program. Task 1. Quarterly technical progress report No. 7, January 1--March 31, 1977
Resumption of initial liquids testing was delayed by OSHA requirements for construction of a catch basin around the fuel tank area and by curtailment of natural gas to CR and D test facilities. The natural gas restriction was lifted in March. Creosote fuel has been received, analyzed and shipped to Hydrocarbon Research, Inc. (HRI) for doping with H-coal sludge. Testing is expected to resume in early May. Fabrication of the confirmation test air cooled nozzle cascade is underway, with EDM drilling of cooling holes in process at Windsor Corporation. Screening tests continued throughout the reporting period. Additional corrosion discs have been removed, metallographically examined and penetration rates observed.
