Abstract
A hollow impingement baffle includes a septum extending between its bottom and top and spaced between its forward and aft edges to define a forward manifold and an aft manifold. The baffle includes an inlet having a forward portion for channeling a first portion of compressed air to the forward manifold, and an aft portion for channeling a second portion of the compressed air into the aft manifold with a predetermined pressure drop for obtaining a lower pressure in the aft manifold relative to a higher pressure in the forward manifold. The baffle includes impingement holes for discharging the compressed air against the inner surface of a surrounding airfoil for the impingement cooling thereof.
