    Abstract: In one aspect the present subject matter is directed to a system for supporting shafts of an indirect-drive turbofan engine. The system includes a fan frame assembly that is coaxially aligned with a centerline of the turbofan engine and positioned forward of a reduction gear that couples a low pressure rotor shaft to a fan shaft. A compressor frame assembly is aligned with the centerline aft of the reduction gear and is positioned axially between a low pressure compressor and a high pressure compressor of the turbofan engine. A turbine frame assembly is coaxially aligned with the centerline and is positioned axially between a high pressure turbine and a low pressure turbine of the turbofan engine. The turbine frame assembly rotatably supports an aft end portion of a high pressure rotor shaft and an aft end portion of the low pressure rotor shaft.

    Abstract: A fairing assembly is provided which is located between a frame hub and an engine casing. The assembly provides for use of a metallic structure in combination with a light weight low alpha material in order to improve engine efficiency and performance. Relative growth between the dissimilar materials is compensated for by a flexible bracket which provides biasing force on one of the assembly components in a cold engine condition as well as allowing for growth at the high temperature operating conditions of the engine.
