E-MAIL: Sharon J. Lebach, slebach@mail.arc.nasa.gov. NASA/ARC plans to issue a Request for Quotation (RFQ) for the continued development of a computer program for the analysis of heat exchangers integrated with airborne power plants. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). NASA/ARC intends to purchase services from Optimal Corporation based on this company's prior development of the ACSYNT, LACEX and HEAP source codes, knowledge of Scaled Composites ERAST design and the heat exchanger design using 3-D computational fluid. The objective is to complete development and provide thorough documentation for the application of the Heat Exchanger Analysis Program (HEAP). Efforts will consist of: 1) Modifying HEAP to provide a generalized single heat exchanger design procedure that allows specification of different combinations of design constraints; 2) Verifying the HEAP Data Base by using a full Navier-Stokes CFD code in an attempt to analyze one heat exchanger core for which good experimental data exists; 3) Documenting the completion of HEAP in a final report; 4) Converting HEAP into a subroutine and integrating it into the NASA AirCraft SYNThesis program (ACSYNT). The Government intends to acquire a commercial service using FAR Part 12. Any referenced notes can be viewed at the following URL: http://genesis.gsfc.nasa.gov/nnotes.htm.
