d between adjacent known cross over holes 55 can also vary along the length l of the barrier 57 the varying width w of each of the known cross over holes 55 and the varying position of each the known cross over holes 55 in relation to one another may result in a non uniform flow of air through the barrier 57 resulting in uneven cooling along the trailing edge 58 fig5 is a sectional view of a trailing edge cooling circuit 60 according to one embodiment of the present invention a cooling fluid typically an airflow c te enters the trailing edge cooling circuit 60 through an inlet opening 62 the airflow c te flows through an inlet passage 64 into a feed passage 66 through the feed passage 66 and exits through a trailing edge 68 the airflow c te from the inlet passage 64 is directed to a lower portion 66 a of the feed passage 66 by a transition 70 which is curved to maintain flow attachment as such a portion of the airflow c te flows unimpeded along the transition 70 providing sufficient airflow to a lower portion 66 a of the feed passage 66 before exiting through the trailing edge 68 notably the transition 70 extends toward the trailing edge 68 a remaining portion of the airflow c te is directed further upward from the lower portion 66 a of the feed passage 66 to an upper portion 66 b of the feed passage 66 by trips strips 72 which are.
