GAS TURBINE ENGINE STATOR VANE FORMED OF CERAMIC MATRIX COMPOSITES AND HAVING ATTACHMENT FLANGES

A stator vane (100) formed of CMC has a radially outer platform (104) and a radially inner platform (106) attached to an airfoil (102). There are a pair of flanges (108, 110; 109, 112) on a side of each of the radially inner platform (106) and radially outer platform (104) which is remote from the a...

Beschreibung
Zusammenfassung:	A stator vane (100) formed of CMC has a radially outer platform (104) and a radially inner platform (106) attached to an airfoil (102). There are a pair of flanges (108, 110; 109, 112) on a side of each of the radially inner platform (106) and radially outer platform (104) which is remote from the airfoil (102). A first of the pair of flanges (108, 110; 109, 112) is associated with the suction side of the airfoil (102) and a second of the pair of flanges (108, 110; 109, 112) is associated with the pressure side of the airfoil (102). The flanges (108, 110; 109, 112) extend in a generally axial direction. The first of the pair of flanges (108, 110; 109, 112) extend over at least a majority of the suction side measured between the leading and trailing edge of the airfoil (102) and the second of the pair of flanges (108, 110; 109, 112) extend over at least a majority of the pressure side measured between the leading and trailing edges of the airfoil (102).
