X-29 Fuel/Auxiliary Oil Systems Thermal Management 860913
The X-29 Fuel/Auxiliary Oil Thermal Management System provides total aircraft accessory oil cooling, including both flight and combined hydraulics, Integrated Drive Generator oil, and Accessory Drive Gearbox oil, with onboard fuel. Fuel cooling rates that are independent of engine demand are achieved through the use of a recirculation loop. Recirculation is minimized by maintaining the engine fuel inlet temperature at the maximum allowable. Fuel cooling results in lower, more uniform subsystem oil temperatures, less ram drag, and smaller, lighter-weight heat exchangers. Initial design studies and laboratory development testing will be discussed, along with comparisons of analytical predictions with flight test results.
