    Abstract: A surface structure having a filmhole pattern is disclosed. The filmhole pattern may be an offset herringbone pattern (52). For instance, the surface structure may have rows of filmholes arranged in filmrows (55), each filmrow (55) divided into groups of filmholes. A first group may be oriented to direct cooling air generally outward over a surface of the surface structure and a second group may be oriented to direct cooling air generally inward over a surface of the surface structure. Between the first group and the second group of filmholes in each filmrow (55), a transition region exists. The adjacent filmrows (55) are arranged to enhance the effectiveness of the convective cooling proximate to the transition regions by causing each filmrow (55) to direct cooling air over the transition region of an adjacent filmrow (55).
