Abstract

Partitions have an airfoil coupled at opposite ends to inner and outer side walls. The side walls each mount radially extending male dovetails. The inner web and outer ring of a diaphragm include complementary shaped dovetail grooves. The male dovetails have reduced diameter portions while the female grooves similarly have corresponding reduced diameter groove portions. The male dovetails are inserted into the female dovetail grooves in an aft direction with stops of the reduced male and female dovetails preventing further movement aft. Seal welds are applied to prevent forward movement of the partitions relative to the web and outer ring.
