A stator assembly of a gas turbine engine includes first and second annular metal stator rims. The stator rims, positioned in parallel, include a plurality of ceramic blades therebetween, each ceramic blade having a rounded nose and a flattened and tapered tail. Each ceramic blade further includes an opening for receiving a mounting pin. The mounting pin mounts between the first and second annular stator rims, clamping and containing the ceramic airfoil therebetween in a position relative to an axis of the turbine engine.

[ What is claimed is:] [1.] In a gas turbine engine, a turbine stator assembly comprising:a mounting pin;first and second annular metal stator rims, each said rim having a first opening for receiving the mounting pin;a ceramic blade configured as an airfoil having a blunt rounded nose and a flattened and tapered tail, said blade having a second opening for comfortably receiving the mounting pin; andthe metallic mounting pin clamping and containing the blade between the stator rims in a predetermined positional relation to an axis of said engine, the ceramic blade being non-rotational,wherein the pin has an end that is tension spring loaded to grow and shrink with engine temperature so that the clamping between the rims retains the blade in the predetermined relation.
