ABSTRACT:
A stator assembly 14 includes an annular support structure, such as an outer case 24, and an element, such as a stator vane assembly 30. The stator vane assembly is restrained against circumferential movement by a key 58 integral with the stator vane which engages the outer case. Various construction details, including a radial projection 82 on the key, are developed which improve the fatigue life of the support structure and enhance the ease of assembly of the structure. In one method of assembling the structure, the method includes the step of using the radial projection on the key as an alignment device.
