摘要： A turbine engine airfoil element has an airfoil having: a pressure side (132) and a suction side (134); and a plurality of spanwise passageway legs (210, 212, 214, 216, 218, 220, 222, 224, 226, 310, 312, 314, 316, 318, 320, 322, 324, 326, 328, 330, 332). The passageway legs (210...332) include: a leading edge impingement cavity (210); and a plurality of main body feed passageway legs (212, 214, 216, 218, 220, 222, 224, 226) along a camber line (190). A wall separates the leading edge impingement cavity (210) from a leading one of the main body feed passageway legs (212), the wall having a suction side section and a pressure side section joining at a junction (364), the junction forming a vertex of an angle (θw) of transverse cross-section of the wall; and a plurality of impingement feed holes through the wall. The plurality of impingement feed holes are larger thickness-wise than span-wise.

摘要： A turbine blade has an attachment root and an airfoil. A cooling passageway system has a plurality of trunks extending from respective inlets along the root inner diameter end from a leading trunk near a first axial end to a trailing trunk near a second axial end; and a plurality of outlets along the airfoil including trailing edge outlets fed by the trailing trunk. Viewed normal to a root end-to-end centerplane: the trailing trunk has a turn passing forward and then rearward; an outside of the turn protrudes forward; and the outside of the turn has a tighter curvature than an inside of the turn.
