An exhaust stack diameter of 3.5 ft has been agreed upon as sufficient to support flow requirements of present TRV and later PRD combustion product and cooling water requirements for the Hot Gas Path Development Test Stand (HGPDTS). The nozzle cooling tube quality control testing equipment has been constructed and is currently being evaluated. Optional positions for the ignitor in the combustor have been defined. One location is in the mixing cup and the other two positions are both downstream in the pilot liner. The copper airfoil machining bid package for the HGPDTS nozzle has been released for quotation. Final assembly of the turbine simulator modified test stand for combustor checkout is nearly complete. Activity in preparation for the Aerodynamic Tests was initiated this month. All test specimens for the heated vane portion of the Air Turbine Test program have been machined and are in the process of being instrumented. An update of the TRV simple cycle performance is presented and the results show an improvement both in output and in efficiency over that previously presented in February 1978. An exhaust temperature limit of 1300/sup 0/F has been set to avoid the costly expense of fabricating the exhaust ducting out of Hastelloy X. The resulting degradation in ambient capability is minimal. Water delivery and distribution through the rotor has been improved by the addition of discrete tubes in the aft core plus lined passages through the rotor to avoid possibilities of stress corrosion cracking. Combustor development activities are reported. Detailed progress and status of the design and development of the turbine nozzle and buckets are discussed. Status of the Materials and Process Programs, as well as the Mechanics of Materials Programs is also presented.
