A -- JOINT TURBINE ADVANCED GAS GENERATOR (JTAGG III) SOL DAAJ02-97-R-0007 DUE 061797 POC Sylvia Ray, Contract Specialist, 757-878-4818/Lauren Sebring, Contracting Officer, 757-878-4828. The Aviation Applied Technology Directorate (AATD), Fort Eustis, Virginia, the Naval Air Systems Command (AIR 4.4), Patuxent River, Maryland, and the Air Force Wright Laboratory Aero Propulsion and Power Directorate (WL/PO), Wright-Patterson Air Force Base, Ohio are procuring a major tri-service research and development program entitled, The Joint Turbine Advanced Gas Generator (JTAGG III)." It is directed toward achieving the Phase III turboshaft/turboprop engine goals of the Integrated High Performance Turbine Engine Technology (IHPTET) Program. The ultimate goal of the IHPTET Program is to double turbine engine propulsion system capability shortly after the turn-of-the-century. The JTAGG program focuses on demonstrating turbine engine technologies which provide major improvements in Specific Fuel Consumption (SFC), Shaft Horsepower-to-Weight (SHP/Wt), and Specific Power (SHP/Wa) for turboshaft/turboprop engines, and thrust-to-weight (FN/Wt) for small turbofan/turbojet engines. These improvements arejudged relative to baseline production engines and are made with no compromise of engine durability or life. The JTAGG program will provide the technology base for future turboshaft/ turboprop and small turbofan/turbojet Engineering and Manufacturing Development (E&MD) and military and commercial derivative engine programs through the development of the necessary component technology, fabrication technology, and test experience. It concentrates on turboshaft/turboprop core engine technologies in the 500 to 15,000 SHP size and turbofan/turbojet core engine technologies up to 15,000 pounds of thrust. The 10 -- 30 lbm/sec airflow class is of primary interest for the JTAGG program. The JTAGG program is a three-step technology development effort permitting the progressive incorporation and testing of new advanced components as the technologies emerge from exploratory development, and/or corporate discretionary programs. The approach is structured to provide an assessment of the new technologies while minimizing the number of demonstrators and duplication of effort. The JTAGG program will significantly reduce the technical risks currently associated with technology transition into new engines, E&MD engines, or component improvement programs, leading to an early acceptance and commitment by the engine/aircraft manufacturers and Services. The primary objective of JTAGG III is to demonstrate the IHPTET Phase III performance, cost, and durability goals. Specifically, the goals are to demonstrate a 40% reduction in SFC, a 120% improvement in SHP/Wt and a 35% reduction in Production and Maintenance costs compared to baseline engines. The life goals are a 6,000-hour operational life and 15,000/7,500 cycles low cycle fatigue life on cold and hot parts, respectively. In addition, JTAGG III will embody technologies which will have a wide range of tri-service applicability, as was the case in JTAGG I & II. Many of these technologies will be common to all the Services, while some will be of a more specific interestto a given Service. Examples of these Service specific items are tolerance to sand and dust ingestion (Army), resistance to salt water corrosion (Navy) and high altitude components (Air Force). JTAGG III will be designed, fabricated, and tested in a gas generator configuration. A derivative engine analysis will be conducted to determine the performance in a turbofan configuration. Specific technologies/ components required to optimize the turbofan performance will be determined. Each Service will award an individual contract under this solicitation. The JTAGG III contract(s) will include detailed design, hardware procurement, fabrication, component testing, assembly, gas generator testing, and post test assessment. A minimum of three gas generator builds of the JTAGG III demonstrator will be tested within the JTAGG III contractual time period. The JTAGG III basic contractual time period will cover 72 months, with the final 4 months being for final data analysis/reporting. This program is classified. Offerorswill require access to and/or generate classified data in the preparation of offers and performance of the resultant contract. Foreign or foreign-owned firms must have a special security agreement with the Defense Security Agency for participation as a prime contractor in the JTAGG III program. Interested offerors must hold a valid facilities security clearance to obtain a copy of this solicitation. All requests for this solicitation must be in writing, no telephonic requests will be honored. See Numbered Note(s): 8, 26. (0065)
