Book Description
This quarterly report covers activities on key tasks for two quarters, from August 1996 to October 1996, and from November 1996 to January 1997, respectively. The reason for combining the two quarterly periods into one report is because of the vastly reduced scope of work remaining on this contract. Allison continued progress on the following tasks during these two quarters: Task 5--Market Study; Task 8.07--Ceramic Vane Design and Evaluation; and Task 9.0--Program Management.

Book Description
The confirmation for the contract modification was received on February 19, 1997. All reports reflect this modification at present. Technical highlights for the reporting period are: first results on steam oxidation behavior of super alloys in steam environment have been achieved; and the tests on TBC evaluation in high thermal gradients could be started. The turbine test rig hardware is progressing well.

Book Description
This Quarterly Technical Progress Report covers the period November 1, 1993, through January 31, 1994, for Phase 11 of the Advanced Turbine Systems (ATS) Program by Solar Turbines Incorporated under DOE Contract No. DE-AC421-93MC30246. The objective of this program is to provide the conceptual design and product development plan for an industrial gas turbine system to operate at a thermal efficiency of 50 percent ({open_quotes}ATS50{close_quotes}) with future improvement to 60 percent ({open_quotes}ATS60{close_quotes}). During the prior quarter Solar's ATS Engine Design Team characterized the intercooled and recuperated (ICR) gas turbine cycle in 1-spool, 2-shaft, and 2-spool 3-shaft arrangements. Fixed and variable geometry free power turbines were compared in both arrangements and sensitivity of all combinations to component performance was determined. Full- and part-load performance were compared over a range of ambient air temperatures. During the quarter just completed, the Team defined four unique and different physical arrangements of the gas turbine components outlined above. These three arrangements were then examined in terms of their ability to support Program goals of thermal efficiency, low emissions, increased reliability, availability and maintainability (RAM), and reduced cost of electrical power production. This work, together with preliminary specification of component cooling needs, suggested that earlier studies of the pressure ratio/firing temperature/thermal efficiency relationship should be re-visited. This accomplished, the effect of total cooling air bleed requirements on thermal efficiency was determined. This will lead to the selection of hot section material capability/cooling air requirements which are able to meet Program goals. As noted in the first quarterly report, where there are apparently conflicting data, later results should take precedence due to the continuing refinement of analytical models.

Book Description
This Quarterly Technical Progress Report covers the period August 3 through October 31, 1993, for Phase II of the Advanced Turbine Systems (ATS) Program by Solar Turbines Incorporated under DOE Contract No. DE-AC21-93MC30246. The objective of this program is to provide the conceptual design and product development plan for an industrial gas turbine system to operate at a thermal efficiency of 50 percent and developable to 60 percent. Solar's ATS Engine Design Team reviewed the intercooled and recuperated (ICR) gas turbine concept defined in the Program proposal, validated certain assumptions associated therewith, and began the process of actualizing this concept in terms of achievable turbomachinery components. Given the probable use of a free power turbine arrangement, both 1-spool and 2-spool compressor arrangements were examined with both fixed and variable turbine geometry. Off-design performance, both part-load and full-load over a range of inlet air temperatures, was examined. During this period certain simplifying assumptions were made regarding the amount of cycle air extracted for use in turbine cooling and the distribution of its return to the cycle. The exact influence of turbine cooling air extraction on cycle performance (thermal efficiency) will be highly dependent upon turbine airfoil material selection, its life/temperature capabilities, etc. Thus, cycle performance will be subject to some degree of change as the design progresses. Even now, improvements made to the cycle performance model will result in variation in presented results. As a general rule, later results will always supersede earlier results when there is an apparent conflict.

Book Description
This Yearly Technical Progress Report covers the period August 3, 1993 through July 31, 1994 for Phase 2 of the Advanced Turbine Systems (ATS) Program by Solar Turbines Incorporated under DOE Contract No. DE-AC421-93MC30246. As allowed by the Contract (Part 3, Section J, Attachment B) this report is also intended to fulfill the requirements for a fourth quarterly report. The objective of Phase 2 of the ATS Program is to provide the conceptual design and product development plan for an ultra-high efficiency, environmentally superior and cost-competitive industrial gas turbine system to be commercialized in the year 2000. During the period covered by this report, Solar has completed three of eight program tasks and has submitted topical reports. These three tasks included a Project Plan submission of information required by NEPA, and the selection of a Gas-Fueled Advanced Turbine System (GFATS). In the latest of the three tasks, Solar's Engineering team identified an intercooled and recuperated (ICR) gas turbine as the eventual outcome of DOE's ATS program coupled with Solar's internal New Product Introduction (NPI) program. This machine, designated ''ATS50'' will operate at a thermal efficiency (turbine shaft power/fuel LHV) of 50 percent, will emit less than 10 parts per million of NOx and will reduce the cost of electricity by 10 percent. It will also demonstrate levels of reliability, availability, maintainability, and durability (RAMD) equal to or better than those of today's gas turbine systems. Current activity is concentrated in three of the remaining five tasks a Market Study, GFATS System Definition and Analysis, and the Design and Test of Critical Components.
