Advanced Integrated Fuel System III, Contract # F33615- 94-C-2498, was awarded to Northrop Grumman Corporation (NGC) by the U. S. Air Force to investigate a new thermal management system based on using a heat exchanger designed to cool 1100°F (593°C) turbine engine bleed air with JP-8+100 fuel (e.g. JP-8 with an additive package that increases fuel thermal stability by 100°F (55°C)). As part of the contract, NGC agreed to test the heat exchanger at the Advanced Reduced Scale Fuel System Simulator facility at Wright-Patterson AFB, OH. This paper documents the test conditions and results from the heat exchanger's first 165 hours of operation.

One of the thrusts of the Advanced Integrated Fuel System (AIFS) initiative, sponsored by the Fuels Branch of the Aero and Propulsion Power Directorate at Wright Laboratories (WL/POSF) with partial funding from the United States Navy, is to realize the potential improvements in aircraft thermal management systems due to the 100 degrees F increase in fuel heat sink capacity of JP-8+100 fuel. This paper summarizes the conceptual design and top-level trade studies conducted by Northrop Grumman Corporation (NGC) under an AIFS contract. These studies examined the air vehicle-level payoffs of JP-8+100 fuel applied to the (1) F/A-18C/D (representing an existing fleet aircraft), (2) F/A-18E/F (representing an aircraft currently under development), and (3) a more-electric aircraft/subsystem integration technology (MEA/SUIT) configured version of an F/A-18 (representing a future aircraft). The objectives and approaches of these studies are presented.
