E-MAIL: Wayne R. Girard, Wayne.R.Girard@grc.nasa.gov. The NASA -- Glenn Research Center is pursuing sources for "Fuel Injector/Mixer Development for future Aircraft Engine Low Emission Combustors". The Ulta-Efficient Engine-Technology (UEET) Emissions Reduction Project will work with the U.S. aeropropulsion industry to develop affordable combustion technologies that will reduce NOx emissions by 70% of the 1996 International Civil Aviation Organization (ICAO) standards, with no increase in other emission constituents (carbon monoxide, smoke, and unburned hydrocarbons) and with comparable NOx reductions during cruise operations. These new combustion concepts and technologies will include lean-burning combustors with advanced controls, and new high-temperature ceramic matrix composite (CMC) materials with reduced cooling air. Low-emissions combustor concepts will be developed and evaluated to achieve major reductions in NOx emissions for both large and regional aircraft engines. This technology needs to be developed by 2004 to enable future environment-friendly engines to enter into service by 2007. These new fuel-efficient engines for large commercial transports will operate at pressure ratios up to 60:1 and combustor exit temperatures to 3200 F. Increases in both temperature and pressure will also be made for the smaller engines for regional aircraft. New concepts and technologies will be required to offset the increase in NOx production brought about by the increase in combustor operating temperatures. The overall goal is to reduce NOx, CO, and UHC production in the landing-takeoff cycle and at cruise as well as reduce the production of CO2 through higher engine efficiency. Fuel injectors/mixers are critical components in the advanced combustor concepts and need to be developed to achieve the low emissions goals. The test program will use jet-A as the primary test fuel. Air pressures will be as high as 60 atmospheres, and flame temperatures as high as 3200+ F. NASA will participate in the design process with combustor codes to guide development of the fuelinjectors/mixers. The NASA -- Glenn Research Center will provide fuel-injector suppliers with conceptual designs. Suppliers will be responsible for the mechanical and thermal design of the injectors for proper fuel and air mixing. Suppliers will also be responsible for fabrication and prototype manufacturing. NASA conceptual designs will consist of fuel-injector, air swirler modules capable of being installed through an engine diffuser case. Typically, there will be 20 to 30 modules per combustor. The modules will consist of multiple fuel injectors, typically one (1) per square inch. The effective airflow per module will be approximately 1.5 to 2 square inches. The fuel injector modules will be delivered to NASA -- Glenn for testing in flame tubes and sector rigs. The test results will be evaluated and used to modify designs for additional testing, in an iterative process to achieve program emission-reduction goals. Tests will be first conducted in flametubes, and on successful completion, will then beapplied and tested in combustor sectors. Following successful sector testing, the modules will be developed for full-annular combustor tests. These fuel injector mixer modules must have the potential to be affordable or competitively priced with production fuel injectors used in the commercial aeropropulsion industry. Vendors must provide evidence of fuel injector detailed design and manufacturing experience. For purposes of this survey, interested parties are requested to limit their capability information to no more than ten (10) pages. The total duration of the effort is expected to be sixty (60) months. Multiple contract awards are anticipated. The Government does not intend to acquire a commercial item using FAR Part 12. See Note 26. The SIC code and size standard are 3724 and 1,000 employees, respectively. If you have already responded to the market survey, previously posted, a response to this notice is not required. The purpose of this announcement is to publicize this procurement and measure the degree of interest and capability of industry in this area of engine research. Interested and responsible sources may submit information on their cabpabilities on or before February 7, 2000, to either of the following individuals: Wayne Girard, NASA -- Glenn Research Center, 21000 Brookpark Rd., Mail Stop 500/305, Cleveland OH 44135 (216) 433-2799 or Clayton Meyers, Project Manager, NASA -- Glenn Research Center, 21000 Brookpark Rd., Mail Stop 60/5, Cleveland, OH 44135 (216) 433-3882. A DRAFT Request for Proposal (RFP) for industry review and comment will be posted on or about January 31, 2000. The FORMAL RFP will be posted approximately thirty-five (35) days thereafter. Posted 01/24/00 (A-SN418277). (0024)
