    Abstract: A gas turbine engine comprises a fan section including a fan hub supporting a plurality of fan blades for rotation relative to a fan case, a shaft rotatable relative to the fan case about an engine center axis, and a geared architecture driven by the shaft to provide driving output to rotate the fan hub. A compressor is positioned forward of the geared architecture and radially inward of the fan blades, with the compressor being driven by the shaft.

    Abstract translation: 燃气涡轮发动机具有风扇部分,该风扇部分包括支撑相对于风扇壳体旋转的多个风扇叶片的风扇轮毂。 轴可相对于发动机中心轴线的风扇壳体旋转。 齿轮架构由轴驱动,并提供驱动输出以旋转风扇轮毂。 压缩机由轴驱动并位于齿轮架构的前方。 压缩机包括至少第一和第二级,其中第一级位于多个风扇叶片的前方,并且第二级定位在多个风扇叶片的后方。 压缩机包括至少一组叶片,其围绕发动机中心轴线沿第一方向旋转,并且至少一组压缩机叶片围绕发动机中心轴线沿第二方向旋转。 第二方向与第一方向相反。
