Precooling heat exchange arrangement integral with mounting structure fairing of gas turbine engine

摘要: A precooling heat exchange arrangement includes a hollow fairing mounted on forward side of an engine mounting structure extending radially across annular fan duct gas turbine engine. The has aerodynamically-shaped external wall disposed in the main air flow through duct, spaced upper and lower internal plenums middle plenum therebetween sealed therefrom. conduit routes hot bleed from to at least one exchanger is fairing. transfer having interior communication with exterior such that fractional portion can divert pass relationship passing for cooling air. An control mechanism provided routing cool core compartment after over structure.
