Abstract: A gas turbine engine (20, 80) has a compressor section (24) including a lower pressure compressor (44, 94) and a higher pressure compressor (52, 100), and a turbine section (28). A core engine housing (90) surrounds the compressor section (24) and the turbine section (28). An outer intermediate housing wall defines an internal chamber (88) between the core housing (90) and the outer intermediate housing (86). A fan rotor (42, 84) and a fan casing (82) surround the fan rotor (42, 84) to define a bypass duct (B) between the fan case (82) and the outer intermediate housing (86). A heat exchanger (108) is mounted in the internal chamber (88) and receives high pressure air for cooling the high pressure air and delivering the high pressure air into the core engine housing (90) to be utilized as cooling air for a component. Air from the lower pressure compressor (44, 94) is utilized to cool the higher pressure air in the heat exchanger (108).

Abstract: A fluid impeller for us in applications requiring superior cavitation erosion resistance. The impeller has a body fabricated from a castable metastable austenitic steel alloy which has a preferred chemical composition in the range of 17.5-18.5% chromium, 0.5-0.75% nickel, 0.45-55% silicon, 0.2-0.25% nitrogen, 15.5-16.0% manganese and 0.1%-0.12% carbon. Quantitative testing has shown cavitation resistance of four to six times that of standard boiler feed pump materials. A method for making cavitation resistant fluid impellers is also disclosed.
