초록

A cooling circuit is provided for the second stage nozzle of a gas turbine. Cooling medium such as air is supplied into a chamber for flow through openings in an impingement plate for impingement cooling of the trailing edge. Convection air is supplied to the trailing edge for combining with the impingement flow. Both series and parallel arrangements of cooling circuits are provided for the aft portion of the vane.
