Abstract
A turboprop engine having a variable pitch propeller driven through a speed reducing transmission. The engine has a compressor section with a low pressure component and a high pressure component. A flow control device is positioned between the low and high pressure components. During takeoff, air from the low pressure component is bypassed, and during cruise, the air from the low pressure component is passed directly through the high pressure component, thus obtaining improved matching of engine components for both takeoff and cruise.
