Abstract
A stator assembly 14 having a spline-type connection between an inner case 24 and an outer case 26 is disclosed. Various construction details are developed, which ensure that the spline-type connection permits relative radial growth between the inner case and the outer case while providing for a rigid interconnection between the cases during blade failures which transfer loads from the outer case to the inner case. In one particular embodiment, the inner case has attached thereto a plurality of spline-type spacers 54 each having an inwardly facing surface 82 which is adapted to engage an outwardly facing surface 74 on a portion of the support structure for the outer case to restrain the outer case against radially outward movement.
