MANIFOLD WITH IMPINGEMENT PLATE FOR THERMAL ADJUSTMENT OF A TURBINE COMPONENT

摘要

An article (100), such as a turbine component, is disclosed including a manifold (102), an article wall (104) having at least one external aperture (114), and a post-impingement cavity (106) disposed between the manifold and the article wall. The manifold (102) includes an impingement plate (108) defining a plenum (110) having a plenum surface (116), and at least one impingement aperture (112). The at least one impingement aperture interfaces with the plenum at an intake aperture (300) having a flow modification structure (302), which, together with the at least one impingement aperture (112), defines an exhaust aperture (304). The manifold exhausts a cooling fluid (118) from the plenum into the intake aperture, through the at least one impingement aperture, out the exhaust aperture, into the post-impingement cavity, and through the at least one external aperture.
