ABSTRACT:
A slip joint interconnects the exhaust gas duct of a gas turbine engine to the hot gas inlet duct of an associated heat exchanger by a flange clamping arrangement. The joint allows translational motion of the heat exchanger in the fore and aft axis relative the engine resulting from thermal expansion in the heat exchanger. In addition, a limited amount of misalignment between the engine exhaust gas duct and the heat exchanger hot gas inlet duct is permitted. The easily assembled simple flange clamping arrangement allows a low clamping pressure and thus a low resistance to slip between the two elements.
