Abstract
Apparatus for reducing the pressure loss imposed upon the working medium gases flowing through an exhaust case of a turbine machine is disclosed. Various construction details which reduce the cross flow of secondary air from the pressure side of one case strut to the opposing side of the adjacent strut are developed. The loss reduction system is built around vortex generators which energize the flow boundary layer at the inner wall of the flow path for the working medium gases.
