ABSTRACT OF THE DISCLOSURE A stator vane assembly is provided, particu- larly for the first row of stationary vanes of a gas turbine, utilizing ceramic vanes. Each individual vane assembly consists of an airfoil vane with a separate end cap at each end for supporting the vane in position. Each vane has an airfoil portion with a tenon portion at each end thereof having a curved surface for engagement in a recess in the adjacent end cap which has a similarly curved surface. The tenons have a different cross-sectional con- figuration than the airfoil portions of the vane such that the area of contact between the tenons and the end caps is greater than the cross-sectional area of the airfoil por- tion and is preferably substantially coextensive with the surface of the recess in the end cap. The tenons termi- nate short of the leading and trailing edges of the airfoil portion so that the tenons are not coextensive with the airfoil in either direction.
