A -- HIGH HEAT SINK FUEL SYSTEM SOL PRK 99-01 DUE 022299 POC Contact Mary Lykins, Contract Negotiator, (937) 255-5310, or Rebecca A. Maddox, Contracting Officer, (937) 255-5310 WEB: click here to view the PRDA Announcement, http://www.wrs.afrl.af.mil/contract/. Air Force Research Laboratory, (AFRL/ PRSF) solicits research proposals for High Heat Sink Fuel System. The purpose of this solicitation is to seek proposals, which address the high heat sink and thermal stability of jet fuels (JP-8+225, JP-900, endothermic, and chemically reacting) in aircraft components and propulsion system hardware. In addition, the objective of this program is to demonstrate the advantages of these fuels in terms of enhanced propulsion system design and reduced life cycle costs. Air vehicles require large fuel heat sink capabilities for cooling airframe and engine components. In particular, for gas turbine engines, it is planned to demonstrate JP-based high heat sink fuel with goals of 500 BTU/lbm, 400 hour on-wing maintenance interval, 2000 hour system life, and +20% heat duty/weight over baseline. For scramjet/combined cycle engines for weapon systems such as hypersonic reconnaissance/strike vehicles, it is planned to demonstrate high heat sink fuel with goals of 1500 BTU/lbm, greater than 15 minute system life, 150 BTU/ft2-second direct cooling and minimal material degradation from fuel attack at 1800oF. The objective is to maximize fuel heat sink and fuel system reliability while minimizing maintenance (coking) using JP-based, more thermally stable fuels (JP-8+225, JP-900, endothermic, or chemically reacting fuels). These fuels will provide heat sink increases of 1.2, 4, and 10 fold, respectively, over JP-8.
