ABSTRACT:
A free floating fairing comprising an outer ring fairing, an inner ring fairing and a three piece replaceable strut fairing define an aerodynamic contour and heat shield for the turbine exhaust case of a gas turbine engine. The material fo the fairing can be selected to optimize heat transfer characteristics to enhance the structural integrity of the supporting structure while assuring the lubrication in the lubricating passages in the struts does not coke and the preload on the support rods is not lost during engine operation. The inner ring fairing serves to hold in place the nose piece of the three piece strut fairing for ease of replacement.
