A -- THERMAL MANAGEMENT RESEARCH FOR POWER GENERATION POC Dr. John E. Leland, Wright Laboratory, WL/POOS-1, 1950 Fifth St, Bldg 18, Wright-Patterson Air Force Base, OH 45433-7251, (513) 255-2922, FAX (513) 476-4781, email: lelandje@wl.wpafb.af.mil. Notice of Contract Action for Thermal Management Research for Power Generation. The Wright Laboratory, Aero Propulsion and Power Directorate, Aerospace Power Division is considering the award of a 52 month program to develop advanced aircraft thermal management concepts for emerging AF power technologies as well as technical support for ongoing research programs in thermal management of aircraft power generation systems. High power/high temperature electronics, electric actuators, switched reluctance machines (SRM) and integrated engine/generator systems are examples of power technologies that will require innovative cooling solutions. By conceiving and investigating advanced techniques, the Aerospace Power Division can identify those concepts that merit subsystem integration analysis and full feasibility studies. The experimental or numerical evaluation of the proposed concepts shall be an integral part of this program. Thermal Management Research for Power Generation in this context includes: actuator cooling, actuator control electronics cooling, rotating machinery, (starters, alternators, generators, fuel pumps, etc.) cooling, windage effects in rotating machinery, power electronics cooling, and high ''g'' and vibration effects on heat transfer mechanisms. Most Thermal Management Research for Power Generation problems can be grouped into one of three broad areas: ELECTRONICS COOLING: High heat flux ()100 W/cm to the second power) and high temperature ()300 degrees Celsius) power electronics are being developed for future military aircraft. Micro and macro scale cooling concepts are desired. The integration of micro and macro scale cooling is a long term goal to be considered. ACTUATOR COOLING: The much larger dissipation rates and lower frequency operation of actuators yield power transients which are manifested by large thermal transients. Furthermore, actuators are often located in airframe extremities where fewer cooling options are available. Autonomous pumped or capillary driven cooling concepts are desired. Techniques which can overcome high speed skin heating problems are a must. ROTATING MACHINERY COOLING: Magnetic and windage losses create high heat loads in high speed rotating machines. The rotor is often the most difficult component to cool because external air cooling increases windage losses and the shaft is the only path for conduction cooling. Confined liquid cooling would require the use of problematic seals. Thus, there is a need for concepts that will yield lower windage losses and increased heat transfer. A thorough knowledge of windage will be necessary to generate such concepts. The refurbishment and operation of an on-site high speed test rig for the study of windage is required for this program. The program will be conducted on-site in the facilities of the Aero Propulsion and Power directorate using specialized government facilities and equipment on research topics which are separate from, but related to those being investigated by government personnel at the same facility. Thus, the source for this program must have the appropriate technical personnel available to be assigned full time at these facilities and personnel and facilities at the source's home office that can support and manage the on-site personnel both technically and administratively. It is anticipated that the Research and Development Streamlined Contracting Procedures (RDSCP) will apply to this acquisition in accordance with DFARS 235.70. A standard request for proposal (RFP) will not be issued. The complete solicitation will appear in a subsequent edition of the Commerce Business Daily. As such, respondents to this notice must include complete address information to the office indicated below in order to receive any supplemental packages/amendments. Firms responding should indicate whether they are, or are not, a socially and economically disadvantaged business, a woman-owned business, a historically black college or university, or minority institution. For this item the general definition to be used to determine whether your firm is small is as follows: ''A small business concern is a concern that is independently owned and operated, is not dominant in the field of operation in which it is bidding on Government contracts and with its affiliates, the number of employees does not exceed 1000 persons.'' SIC Code 8731 applies. ''Concern means any business entity organization for profit with a place of business in the United States, its possessions, Puerto Rico, or the Trust Territory of the Pacific Islands, including but not limited to an individual, partnership, corporation, joint venture, association, or cooperation.'' The Air Force reserves the right to consider a small business set-aside based upon responses hereto. Small business respondents should provide a statement of capabilities to assist the Air Force in making a set-aside decision. All respondents shall include in any request, their assigned Commercial and Government Entity Code. Responses should be sent to: ATTN: Roger Collins, WL/POKA, Bldg 7, 2530 C St, Wright-Patterson AFB OH 45433-7607. Non-technical assistance may be secured by calling (513) 255-3825. An Ombudsman has been established for this acquisition. The only purpose of the Ombudsman is to receive and communicate serious concerns from potential offerors when an offeror prefers not to use established channels to communicate his concern during the proposal development phase of this acquisition. Potential offerors should use established channels to request information, pose questions, and voice concerns before resorting to use of the Ombudsman. Potential offerors are invited to contact ASC's Ombudsman, ASC/CY, at (513) 255-1427 with serious concerns only. Direct all routine communication concerning this acquisition to Roger Collins, Contract Negotiator, WL/POKA, Bldg 7, 2530 C St, Wright-Patterson AFB OH 45433-7607. Closing date for submission of responses is thirty (30) calendar days from the publication of this notice. Firms should reference (POK-96-04) in their responses. (0011)
