Zusammenfassung:	Components (300, 400) for gas turbine engines (20) are provided. The components include a platform (302, 402, 502, 602), the platform defining a platform cavity (310, 410a, 410b, 610) on a first side (644), an airfoil (306, 308, 406) extending from a second side (646) of the platform, wherein the airfoil comprises at least one airfoil cavity (418, 618) located within the airfoil, the at least one airfoil cavity fluidly connected to the platform cavity through an airfoil cavity inlet (312, 314, 412, 618a, 618b), and a platform flow turning element (316, 416, 516, 616) positioned on the first side of the platform, the platform flow turning element having a turning portion (420, 520, 620a, 620b) and a tapering portion (422, 522, 622), wherein the turning portion directs incoming air to turn from the platform cavity into the airfoil cavity and the tapering portion extends through the airfoil cavity inlet and into the airfoil cavity.
