Abstract
Flow rate of coolant air is increased upon elevated nozzle gas temperatures to increase nozzle liner cooling effect. A hot side curved plate is superposed over a cold side curved plate which overlays a pressurized cooling air cavity. First and second sets of apertures are formed through the first and second plates respectively. At low temperature operation, the gap between the plates is small and the staggering of the apertures restricts the flow rate of cooling gas through the plates. As temperatures rise, the hot side plate thermally expands and the gap between the plates increases to reduce the mechanical impedance effect of the staggering and to thus increase coolant flow rates.
