ABSTRACT:
A two part vane (38) comprises a metallic downstream portion (42) and a high temperature leading edge insert (40) disposed between two retaining buttons (46,48) loosely fit into recesses (50) formed in the inner platform (52) and the outer platform. The separation between the leading edge insert (40) and the downstream portion (42) creates two cooling louvers (64,66) for conducting cooling air from an internal cavity (58) through the cooling louvers (64,66) and down the surfaces (54,56) of the downstream portion (42).
