Abstract
A stator vane formed of CMC has a radially outer platform and a radially inner platform attached to an airfoil. There are a pair of flanges on a side of each of the radially inner platform and radially outer platform which is remote from the airfoil. A first of the pair of flanges is associated with the suction side of the airfoil and a second of the pair of flanges is associated with the pressure side of the airfoil. The flanges extend in a generally axial direction. The first of the pair of flanges extend over at least a majority of the suction side measured between the leading and trailing edge of the airfoil and the second of the pair of flanges extend over at least a majority of the pressure side measured between the leading and trailing edges of the airfoil.
