Abstract:
1. An integrated outlet guide vane assembly for turbomachinery, said turbomachinery having a central axis of rotation and a defined direction of rotation about said central axis, said integrated outlet guide vane assembly comprising: at least one outlet guide vane, said at least one outlet guide vane comprising an airfoil having a leading edge and a trailing edge, said at least one outlet guide vane further having a non-zero angle of lean in said direction of rotation and a non-zero sweep angle relative to a line perpendicular to said central axis; and at least one bifurcation, said at least one bifurcation having a leading edge and a trailing edge and forming a hollow duct-like structure through which various connections of the turbomachinery can pass without causing disruption to airflow, said leading edge of said at least one bifurcation having a non-zero angle of lean in said direction of rotation and a non-zero sweep angle relative to a line perpendicular to said central axis; wherein said trailing edge of said at least one outlet guide vane is faired into said leading edge of said at least one bifurcation.
