Abstract

An air cooled stator vane or the like for a gas turbine engine is constructed to include a plurality of axially and radially spaced pockets formed on the outer surfaces of the airfoil sections. Air is directed into the pocket on one end of a passage defined by the pocket to impinge on the back wall of the pocket, change directions and flow through the passage and discharge into the gas path as a film of cooling air coalesced by slots formed at the end of the pocket. The outer wall can be cast in its entirety or fabricated from sheet metal sheaths supported to a cast inner shell. The pockets are fed cooling air through a central passage in the stator vane or through impingement inserts disposed in the central passage.
