Specifications for the Hot Gas Path Development Test Stand (HGPDTS) Closed Loop Water Cooling System Control Valves have been released and included in a bid package. Piping diagrams have been revised to comply with updated flow diagrams. Final bids have been received on heat exchangers. A detailed manufacturing plan for the HGPDTS first stage nozzle is being prepared. TRW has initiated the manufacture of the core tooling needed for the second stage nozzles. A conceptual design of the ''simulated'' first stage nozzle is under way. This nozzle is used for combustor development tests only. Modifications to the existing test section of the Turbine Simulator are complete. Reassembly with the metal ceramic hybrid combustor is under way. Combustor testing will begin shortly. Design of the test specimen is continuing. Material selection for the composite specimen have been made. Velocity distribution determination of the flow thru a cascade continued. New heat gauges for use in the shock tunnel tests have been fabricated to replace the worn and solvent affected sensors. Detailed design of the Pilot Gas Clean Up System continues. DOE purchased approval on the pressure vessels has been received. Bid packages for plant construction are being prepared. The horizontal cooling passage test specimens are ready for test in the Motorized Rig. Fabrication of the test specimens for the Air Turbine tests is in progress. Updates to the liquid and gas fueled combined cycle power plant designs are reported. A change in the design of the water delivery path from the bore to the bolt circle to that of a cone with discrete water tubes is being analyzed. Justification for the two stage sectoral combustor is presented in a unique graphical form. Results of a vibrational analysis on the combustor and fuel pipe are discussed. Current status of the design, manufacture, materials, and process development for each stage of the turbine (nozzles and buckets) are presented.
