A -- NUMERICAL PROPULSION SYSTEM SIMULATOR (NPSS) SOL RFP3-080449F DUE 091797 POC John P. Kuminski, Contracting Officer, Phone (216) 433-2453, Fax (216) 433-5489, Email John.P.Kuminski@lerc.nasa.gov WEB: Click here for the latest information about this notice, http://procurement.nasa.gov/EPS/LeRC/date.html#RFP3-080449F. E-MAIL: John P. Kuminski, John.P.Kuminski@lerc.nasa.gov. NASA LeRC plans to issue a Request for Proposal (RFP) to acquire capabilities which contribute to the development of the Numerical Propulsion System Simulation (NPSS) system. A draft solicitation was issued on June 27, 1997 with a deadline for comments of July 14, 1997. The NPSS is being developed to enable simulations of full aeropropulsion systems in sufficient detail to resolve critical design issues early in the design process before hardware is built. The NPSS project is focused on the integration of multiple disciplines such as aerodynamics, structures and heat transfer with computing and communication technologies to capture complex physical processes in a timely and cost-effective manner. The vision for NPSS is to be a "numerical test cell" that enables full engine simulation overnight on cost effective computing platforms. There are several key elements within NPSS that are required to achieve this capability: 1) clear data nterfaces through the development and/or use of data exchange standards, 2) modular and flexible program construction through the use of object-oriented programming, 3) integrated multilevel of complexity analysis techniques that capture the appropriate physics at the appropriate level of fidelity, 4) multidisciplinary coupling techniques, and finally 5) high performance parallel and distributed computing. The objective of the program is to develop design and analysis tools for aircraft engine applications such as cooled high pressure turbines (HPT) and high pressure compressors (HPC). Focused applications are to be used to guide the development and demonstration of the variable complexity analysis, multidisciplinary, and reduction in time-to-solution aspects of the NPSS. The programmatic need for the solicitation is to meet the FY 99 milestone in High Performance Computing and communication Program (HPCCP) for reduction in time-to-solution and the Base Research & Technology (R&T) milestone to develop the variable complexity analysis and multidisciplinary tools integrated with the NPSS architecture. The technical point of contact for this procurement is Dr. Charles Lawrence, Aerospace Engineer. He can be reached by telephone at (216) 433-6048, by fax at (216) 433-5188, or by E-mail at Chales.Lawrence@lerc.nasa.gov. The estimated period of performance of this technical is 24 months. The date set for release of the solicitation is approximate. In accordance with NASA FAR Supplement clause 1852.215-84, an ombudsman has been appointed to hear concerns from offerors, potential offerors and contractors during the preaward and postaward phases of this acquisition. HOWEVER, BEFORE CONSULTING WITH ANY OMBUDSMAN, parties should first address their concerns, issues, disagreements, and/or recommendations to the contracting officer for resolution. If resolution cannot be made by the contracting officer, concerned parties may call the installation ombudsman, Dr. Julian Earls, at (216) 433-3014. Concerns and issues which cannot be resolved at the installation may be referred to the NASA ombudsman, the Deputy Administrator for Procurement, at (202) 358-2090. PLEASE DO NOT CONTACT THE OMBUDSMAN TO REQUEST COPIES OF THE SOLICITATION, VERIFY OFFER DUE DATE, CLARIFY TECHNICAL REQUIREMENTS, ETC. Requests of this nature should be made either to the contracting officer or as specified elsewhere in this document. The anticipated release date of RFP3-080449 is on or about July 31, 1997 with an anticipated proposal due date of on or about September 17, 1997. A firm closing date for receipt of offers will be stated in the solicitation. All responsible sources may submit a proposal which shall be considered by the agency. The solicitation and any documents related to this procurement will be available over the Internet. These documents will be in ASCII or RTF format and will reside on a World-Wide Web (WWW) server, which may be accessed using a WWW browser application. The WWW address, or URL, of the NASA/LeRC Business Opportunities page is http://procurement.nasa.gov/EPS/LeRC/class.html. It is the offeror's responsibility to monitor this site 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). Hard copies will not be avaialble.
