Description

NASA/LaRC plans to issue a NASA Research Announcement (NRA) for research in the areas of revolutionary airframe-noise modeling and noise reduction concepts. The objective of this NRA is to stimulate interested parties to submit proposals for truly innovative research in these areas. Revolutionary Airframe-Noise Modeling and Noise Reduction Concepts-Proposals are sought for clever approaches to model and/or significantly reduce airframe noise. Proposals may concentrate either on the noise-modeling aspects, the noise-reduction aspects, or both. Offerors may propose experimental work, computational work, both, or neither, depending upon their specific requirements. Particular areas in which current concepts appear to be inadequate include the modeling of flap-edge and landing-gear noise and noise-reduction concepts for landing gear. However, proposals demonstrating exceptional creativity within the limits of feasibility will be given preference over others, regardless of the particular problem being addressed or the methods used. Proposals for airframe-noise modeling should be based on the physics of the noise-production mechanisms and be generically applicable to multiple environments where that particular physical mechanism dominates. Proposals may focus on known mechanisms relevant to specific airframe-noise sources, or they may focus broadly on modeling methods applicable to entire airframes. The proposals should emphasize clever concepts, rather than simply the tackling of difficult problems. Significant preference will be given to proposals that demonstrate how innovative thinking can make difficult problems more tractable. With respect to airframe-noise reduction, proposals will be entertained that have the potential to reduce airframe noise by at least 5dB over 1997 best-in-fleet technology. Proposals may focus on a particular technology that would enable noise reduction for an existing airframe, or on a yet-to-be designed airframe. Proposals for noise-reduction concepts should also include an identification of the relevant physical mechanisms that are being altered to achieve the noise reduction. Clearly, the noise-reduction modifications suggested must minimize any associated performance penalties. The Government intends to fund a maximum of 2 proposals, each for a period of performance from the date of award through approximately September of 2005. The maximum total funding (in thousands) is anticipated to be: $100K for FY 2002, $205K for FY 2003, $160K for FY 2004, and $165K for FY 2005. Proposals that involve significant experimental work are likely to be funded at higher levels than those focusing more on analytical-computational work. A preferred funding split for the two proposals is indicated in Table 1 below. Although the funding scenario indicated in the table is preferred, the Government may choose to alter the funding split in any manner that it feels optimizes the value obtained from the funded proposals. Table 1: Experimental Project: FY 02: 50K, FY 03: 150K, FY 04: 100K, FY 05: 100K Analytical/Computational Project: FY 02: 50K, FY 03: 55K, FY 04: 60K, FY 05: 65K Totals: FY 02: 100K, FY 03: 205K, FY 04: 160K, FY 05: 165K Interested parties may submit separate proposals for different activities or may submit a single proposal including multiple activities. Participation in this NRA is open to all organizations or teams of organizations from industry, educational institutions, nonprofit organizations (includes not-for-profit organizations), and U.S. Government agencies (acting independently or as part of a team). Communications concerning this NRA, from receipt of proposals through selection announcement, between the parties submitting proposals and the Government shall be made through the Contracting Officer. All qualified responsible sources may submit an offer, which shall be considered by the Agency. The anticipated release date of the NRA is on or about June 18, 2001, with an anticipated proposal due date ninety (90) days after release. The solicitation and any documents related to this procurement will be available over the Internet. These documents will be in Microsoft Office Suite (Word 6.0, Excel 5.0, Power Point 4.0) format and will reside on a World Wide Web (WWW) server, which may be accessed using a WWW browser application.

Prospective offerors shall notify this office of their intent to submit an offer. It is the offeror's responsibility to monitor this site and/or the CBD for the release of the solicitation and amendments (if any). Potential offerors will be responsible for downloading their own copy of the solicitation and amendments (if any).
