Abstract:
An airfoil component for a gas turbine engine includes a platform. The airfoil component includes a flow path surface from which an airfoil extends. A laterally extending aft surface is adjacent to the flow path surface. A contoured surface adjoins the flow path surface and the aft surface. An airfoil component for a gas turbine engine includes a platform. The airfoil component includes a flow path surface from which an airfoil extends. A laterally extending aft surface is adjacent to the flow path surface. A contoured surface adjoins the flow path surface and the aft surface. The aft surface extends from a first aft edge to a second aft edge at a circumferentially extending edge. The contoured surface is arranged inboard from at least one of the first and second edges.

PROBLEM TO BE SOLVED: To remove particulates from cooling air and efficiently cool a front edge region. SOLUTION: An air foil capable of cooling having a passage to blow out particulates brought by cooling air is opened. Various details of a structure supply cooling air to front edges 60, 69 of the air foil. A chord directional duct 100 is extended to an inlet of a rear part passage extending in the blade length direction passing through a supply passage 92 extending in the blade length direction, a part of cooling air and particulates from the duct 100 are directed to the inside of the rear passage through an inlet 72 of the supply passage 92 by amomemtum effect, and most of a flow of cooling air is directed to the supply passage 92 to cool the front edges 60, 69 of the air foil.
Abstract:
A coolable airfoil has a passage 94 for discharging particulates entrained in cooling air to provide clean cooling air to the leading edge 60 of the airfoil. A chordwise duct 100 extends past a spanwisely extending supply passage 92 to the inlet of a spanwisely extending rear passage 94 such that momentum effects direct the flow of a portion of cooling air and particulates from the duct, past the entrance of the supply passage 92 and into the rear passage 94. The rear passage 94 has a purge hole 96 through which the particulates may be removed.

Abstract:
An airfoil for a gas turbine engine includes pressure and suction surfaces that are provided by pressure and suction walls extending in a radial direction and joined at a leading edge and a trailing edge. A cooling passage is arranged between the pressure and suction walls and extending to the trailing edge. The cooling passage terminates in a trailing edge exit that is arranged in the trailing edge. Multiple rows of pedestals include a first row of pedestals that join the pressure and suction walls. The first row of pedestals is arranged closest to the trailing edge but interiorly from the trailing edge thereby leaving the trailing edge exit unobstructed.
