A -- ENGINE VALIDATION OF NOISE REDUCTION CONCEPTS POC Ruben Del Rosario, Project Manager, (216) 433-5679, MS 11-3. The Lewis Research Center is planning a procurement to validate in an Engine Test noise reduction concepts and technologies that have evolved from model testing. Model tests have been performed to develop fan and jet noise reduction concepts through advanced fan stage designs, mixers, active noise control and liners. The Advanced Subsonic Technologies' Noise Reduction Program goal is to validate technology that reduces engine noise 6EPNdB and improves nacelle suppression effectiveness by 50% relative to 1992, technology. It is desirable to identify engines that can either be furnished at no cost to the program and/or be tested in conjunction with another test program. Engine tests need to be done, either statically or in a large aeroacoustic wind tunnel, to verify that model data results can be realized in an engine environment. All interested parties may submit information for evaluation of their R&D capabilities to the above project manager. See Numbered Note: 25. (0254)
