Description

NASA/LaRC intends to issue a NASA Research Announcement for research, development, prototyping, and implementation of revolutionary engine/airframe configurations, unconventional acoustic liner concepts, and innovative, high risk, acoustic liner concepts for implementation in commercial aircraft engine nacelles. The objective of this NRA is to stimulate interested parties to submit proposals for research, development, prototyping, and implementation of revolutionary airframe and engine system noise reduction. There are two major proposal sections of this NRA. Section I, the Propulsion Airframe Aeroacoustics Section, contains two topic areas: (1) Revolutionary Propulsion Airframe Integration -- Proposals are sought in this topic for concepts that take advantage of revolutionary engine/airframe configurations in order to produce substantial (10-20 EPNdB relative to 1997 best-in-fleet) reductions in noise specifically because of the unique technology of the configuration. Proposals may focus on a particular technology that would enable noise reduction for an existing unconventional propulsion airframe system concept or on system level analysis of an innovative concept that would then be followed by development of enabling technology in future years. Proposals could also include physics-based prediction methods that use a minimum of empiricism to predict the various installation effects and give physical insight into the noise generating mechanisms and their relative strengths. (2) Acoustic Liner Concepts for Unconventional Airframe Locations -- Proposals are sought for unconventional acoustic liner concepts that could substantially reduce reflected noise while also addressing the installation and performance issues that such a concept would involve. Also sought would be proposals for other methods of reducing noise that is specifically attributable to installation effects of engines on conventional subsonic airliner transports. Section II, the Liner Technology Section, contains one topic area: (1) Innovative Liner Concepts -- Proposals are sought to identify and assess innovative, high risk, acoustic liner concepts for implementation in commercial aircraft engine nacelles. These concepts must offer potential to help achieve the long-term NASA goals (10 EPNdB in 10 years and 20 EPNdB in 25 years relative to 1997). Physics-based models will be developed for the selected concepts, and will be assessed in realistic laboratory environments. A 4-year period of performance is anticipated for both Sections I and II, which includes a 2-year basic and a 2-year option period. The Government intends to fund 1 or 2 proposals within each topic area. The maximum funding (in thousands) available for each topic area is as follows: Revolutionary Propulsion Airframe Aeroacoustics -- $150 for FY 2002, $150 for FY 2003, $200 for FY 2004 and $200 for FY 2005; Acoustic Liner Concepts for Unconventional Airframe Locations -- $100 for FY 2002, $100 for FY 2003, $200 for FY 2004 and $200 for FY 2005; and Innovative Liner Concepts -- $100 for FY 2002, $100 for FY 2003, $200 for FY 2004 and $200 for FY 2005. Interested parties that address more than one topic area must do so in separate proposals. Proposals must specify which of the two sections (I or II) is being addressed. 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). Multiple awards are anticipated as a result of this NRA. 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 April 30, 2001, with an anticipated proposal due date sixty (60) days after release. An ombudsman has been appointed -- See NASA Specific Note "B". 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.
