Progress in the design, fabrication and testing of components for high temperature gas turbines for combined-cycle power plants is reported. Hot gas path development test stand fabrication is continuing. The fabrication status of the two first stage nozzles to be tested in the Turbine Simulator is reported. Shock tunnel test section calibration data is presented which verifies the new location of the tine of arrival sensors. All construction work on the PGCUS is completed. Aerodynamic component testing of endwall configurations has started. Testing of the new radial channel heat transfer specimens in the motorized test rig is continuing. A correction factor to be used with the air turbine heat transfer test results, to account for the inoperative leading edge heaters when the test was conducted, is presented. An analysis of the compressor discharge casing strut spring rates was completed. Features to expedite the fabrication of the sectoral combustor to be tested in the HGPDTS are discussed. Additional details regarding the combustor design analysis are presented. All planned wind tunnel testing in support of the combustor development have been completed. Data from the most recently completed heat transfer coefficient test are being reduced. A re-evaluation of the thermal strain in the trailing edge of the first stage nozzle, with the effects of the initial hot isostatically pressed (HIP) cycle superimposed, has been completed. The design remains compatible with the LCF design criteria. An alternative concept for convective shroud cooling is described. Complete status of the materials and processes, and mechanics of materials tasks are discussed.
