ABSTRACT:
A coolable wall element which is adapted for combined impingement and transpiration cooling in environments where the pressure differential across the wall element differs substantially with physical position along the wall is disclosed. Techniques varying the proportion of impingement to transpiration cooling along the wall are developed. The wall element is shown in one embodiment as forming a portion of the wall of an air-foil adapted for use in the turbine section of a gas turbine engine.
