SOURCES SOUGHT SYNOPSIS ULTRA-EFFICIENT ENGINE TECHNOLOGY (UEET) PROGRAM To determine the appropriate level of subcontracting goals and/or potential participation in the UEET program by the small business community, the NASA Glenn Research Center, Cleveland, Ohio, is seeking capability statements from small, small disadvantaged (SDB), women-owned small (WOB), and HUB Zone small businesses. Statements are also being sought from Historically Black Colleges and Universities (HBCU) and other Minority Educational Institutions (OMEI). Capabilities being sought include systems integration and assessment; NOx emissions reductions; highly-loaded turbomachinery; high-performance materials and structures; and propulsion airframe integration. The UEET Program hopes to identify qualified participants this year. Background NASA's role in civil aeronautics is to develop high risk, high payoff technologies to meet critical national aviation challenges. Currently, a high priority national challenge is to ensure U.S. leadership in aviation in the face of growing air traffic volume, new safety requirements, and increasingly stringent noise and emissions standards. NASA has a successful history of leading the development of aggressive high payoff technology in high-risk areas, taking a proactive approach in developing technology that will be required for meeting anticipated future requirements and for forming the technical basis to guide policy. Long range scenarios developed under the auspices of the International Civil Aviation Organization (ICAO) foresee continuing worldwide growth for commercial aviation through the middle of this new century. Given the current constraints on growth due to noise and emissions requirements, propulsion will play a key, lead role in finding viable solutions. Propulsion also plays a critical role in enabling advanced aircraft designs and concepts required to achieve dramatic improvements in efficiencies of operations. Achievable overall cycle pressure ratio and turbine inlet temperature levels limit today's engine designs. Increases in both parameters are required to make improvements in performance and efficiency, as well as improvements in global climate impact. Strategic partnerships will be sought and formed with the Department of Defense, the Department of Energy, the Environmental Protection Agency, and the Federal Aviation Administration on technology development and technology requirements definition. This program will also require strong involvement from the U.S. aerospace industry, including the small business community, for implementation and transfer of technologies into aerospace systems. The primary objective of the Ultra-Efficient Engine Technology Program is to address two of the most critical propulsion issues: performance/efficiency and reduced emissions. High performance, low emissions engine systems will lead to significant improvements in local air quality and minimum impact on ozone depletion/level resulting in an overall reduction in aviation's contribution to global warming. The UEET program will address local air quality concerns by developing technologies to reduce nitrogen oxide (NOx) emissions by 70% at landing and take-off (LTO) conditions per the 1996 International Civil Aviation Organization (ICAO) standards. It will also address potential ozone depletion concerns by demonstrating combustor technologies that enable no discernible aircraft impact on the ozone layer during cruise operation (up to a 90 percent reduction). This program should enable the U.S. to be competitive in developing very low emissions propulsion systems. Additionally, the UEET program will address the potential impact of long term aviation growth on the climate. It will assume carbon-based jet fuel as the aircraft fuel. It will also use critical propulsion technologies to achieve dramatic efficiencies in reducing carbon dioxide (CO2) emissions and effecting an overall fuel savings of about 15% for large subsonic transports or as much as 8% for supersonic and/or small aircraft. The resultant fuel savings represent cost benefits to the traveling public. What Are We Seeking? The UEET program aims to develop and deliver revolutionary propulsion technologies to increase performance and efficiency at the component and/or subsystem level. The program will rely on strategic partnerships and opportunities within the aerospace industry and the government sector. To help ensure that technology maturation and application development are at an appropriate readiness level and meet program objectives, the program will provide investments in five focused areas. Each area or project will be assessed based on minimum technical success requirements. The overall success of the UEET program will be determined based on analytical integration of the technologies into system level assessments against two primary program metrics: (1) overall fuel savings of 8 to 15% and (2) landing to take-off NOx emissions reduction of 70%. In light of the above, the UEET program is now actively seeking small businesses, SDB's, WOB's, HUB Zone small businesses, HBCU's, and OMEI's with experience and/or capability in the following five focused areas: 1.0 Systems Integration and Assessment, which will 7 Provide system level guidance for programmatic decisions; 7 Provide guidance to the development of UEET technologies through system trade studies; 7 Provide technology progress assessment through metrics tracking and rollup; 7 Assess the effects of engine exhaust products on the atmosphere and humans; and 7 Perform high fidelity system simulations to reduce development time. 2.0 NOx Emissions Reductions The Emissions Reduction Project will work with U.S. industry to provide technology readiness to reduce combustion emissions of future aircraft and 7 Demonstrate landing/takeoff NOx emission reductions in full annular low emission combustors (TRL 5) of at least 70% of the 1996 ICAO limits for future large and regional subsonic engine (55:1 & 30:1 Pr ) combustors with corresponding reductions in cruise NOx levels and no increases in other emission constituents (CO, smoke, and unburned hydrocarbons); 7 Demonstrate in large-scale sector ultra low cruise NOx < 4 EI to minimize atmospheric impact of future supersonic aircraft; and 7 Improve and validate the combustor design codes to reduce the design and development cycle time for low emission combustors. Also, improved engine fuel efficiencies is an objective of the UEET Program. Improved fuel-efficient engines will use higher engine pressure ratios of 55:1 to 60:1 and higher turbine rotor inlet temperatures of 31000F for large subsonic engines. Limited increases in both pressure and temperature will also occur for the more efficient smaller regional engine. As in the past, new combustor con-cepts and technologies will be required to produce cleaner burning combustors to offset the increased NOx produced by these more fuel-efficient engines. The Composite Matrix Composite material being developed by the Materials and Structures Project (addressed below) for combustor liners and the turbine vane will permit these components to operate with reduced cooling air and with combustor exit temperatures of 3300+0F. The improved fuel-efficient engine burning less fuel and with reduced cooling air directly contribute to LTO and cruise. 3.0 Highly-Loaded Turbomachinery In order to meet the overall UEET program metric of overall CO2 reductions of 15% for large subsonic transports and 8% for supersonic and/or small aircraft, the objectives of the Highly-Loaded Turbomachinery Project are: 7 Turbomachinery component weight reduction of 20% through close-coupling of fan stages and stage-count reduction; 7 Increased component efficiency of +1% to +2% through better 3D flow management; 7 Increased average stage loading of +50% through flow control; 7 Increased turbine rotor inlet temperature capability of +4000 F at commercial life through enhanced cooling configurations; and 7 Reduced cooling flow requirement by -25% through enhanced cooling effectiveness. 4.0 Materials and Structures for High Performance The major objectivesof the Materials and Structures for High Performance Project are to 7 Develop high temperature disk and airfoil materials for high-performance, high-efficiency propulsion systems and validate advanced material systems; 7 Develop a ceramic matrix composite (CMC) material system and process for low NOX combustor liner and turbine vane, and demonstrate durability of liner/vane sub-components in rig tests; 7 Expand the use of polymer matrix composites (PMC's) in engine structures by demonstrating durability and low-cost fabrication processes for environmentally friendly PMC with 550oF temperature capability; and 7 Decrease weight of supersonic exhaust nozzles through innovative lightweight material, structural, and aerodynamic concepts without sacrificing nozzle performance. 5.0 Propulsion Airframe Integration The Propulsion Airframe Integration (PAI) Project supports the UEET Program goal to reduce fuel burn and CO2 emissions by 15% for large subsonic transport aircraft and by as much as 8% for supersonic and/or small aircraft. The specific objectives for each PAI technology challenge are to: 7 Demonstrate enabling PAI computational and/or experimental methods for advanced configurations with 20% or greater fuel-burn reduction compared to 1997 best-in-service Boeing 777; 7 Demonstrate 50% or greater reduction in length of S-inlets compared to best-in-service USAF/Lockheed Martin F-22; and 7 Demonstrate efficient airframe boundary layer ingestion into the inlet with no loss in inlet pressure recovery or increase in inlet distortion.
