摘要: A turbine airfoil comprises a suction sidewall, a pressure sidewall, a tip wall, and a tip leakage control channel. Each sidewall extends spanwise from an airfoil base and chordwise between a leading edge and a trailing edge. The tip wall extends chordwise from the leading edge to the trailing edge and joins respective outer spanwise ends of the suction and pressure sidewalls. The tip leakage control channel has an inlet and an outlet recessed into an outer surface of the tip wall. An inlet of the channel begins proximate a junction of the airfoil pressure sidewall and the tip wall. An outlet of the channel terminates at a recessed portion of the junction of the tip wall and the suction sidewall.

摘要: A method for forming a cooling hole extending from an inlet on a first surface of a wall to an outlet on a second surface of the wall includes forming a diffusing section of the cooling hole, and a trailing edge on the outlet by electrical discharge machining, and forming longitudinal lobes in the diffusing section. The metering section extends from the inlet on a first surface of the wall towards the second surface of the wall. The diffusing section extends from the outlet to one end of a metering section located between the inlet and the outlet. The outlet is substantially linear or convex at the trailing edge and the lobes are separated by longitudinal ridges.

摘要: A turbine blade for a gas turbine engine includes an airfoil including leading and trailing edges joined by spaced apart pressure and suction sides to provide an exterior airfoil surface extending in a radial direction. The trailing edge is arranged on an aft side of the turbine blade. A root supports a platform from which the airfoil extends and a cooling passage extends within the root in the radial direction to the airfoil. A lower wing is arranged beneath the platform on the aft side and extends in an axial direction to provide a U-shaped channel with the platform that extends in a circumferential direction. An impingement hole extends from the U-channel to the cooling passage.

摘要: A coolable vane (12) for a turbomachine includes an airfoil (16) with a pair of imperforate ribs (42, 44) that extend laterally across the airfoil. The ribs have suction side termini (52, 56) and pressure side termini (54, 58). The suction side termini chordwisely delimit a segment SS of the airfoil suction wall (28) so that the ribs and the suction wall segment bound an internal plenum (48) for distributing a pressurized coolant spanwisely through the interior of the airfoil. An array of film cooling holes (84) penetrates the suction wall segment and is the exclusive avenue for conveying coolant from the plenum to a working medium fluid flowpath. Accordingly, relatively low pressure coolant may be supplied to the plenum without the risk of backflow or spanwise discontinuities in the surface cooling film. In one specific embodiment of the invention, the suction side rib termini (52, 56) straddle a point of minimum fluid pressure along the suction surface (38) so that positive coolant flow and spanwise continuity of the cooling film can be realized with coolant of the lowest possible pressure and without exposing the suction wall segment SS to excessive stress.
摘要翻译: 用于涡轮机的可冷却叶片(12)包括翼型件(16),其具有横跨翼型延伸的一对无孔肋条(42,44)。 肋具有吸入侧端部(52,56)和压力侧端子(54,58)。 吸入侧端部弦向地限定翼型件抽吸壁(28)的段SS,使得肋和抽吸壁段结合内部增压室(48),用于将加压的冷却剂分流穿过翼型件的内部。 一组薄膜冷却孔(84)穿透吸壁部分,是将冷却剂从气室输送到工作介质流体流路的专用通道。 因此,可以将相对低压的冷却剂供应到集气室,而不会在表面冷却膜中产生回流或翼展方向不连续的风险。 在本发明的一个具体实施例中,吸入侧肋端部(52,56)沿着吸力表面(38)跨过最小流体压力点,使得冷却剂流的正向冷却剂流动和翼展方向连续性可以通过 压力尽可能低,并且不会使吸力壁段SS暴露于过度的压力。

摘要: A cooled rotor assembly for a gas turbine engine includes rotor blades (48) and a plurality of cover plates (86a) retained in the blade attachment slots (34) of a rotor disk (30). Each blade has a platform (46) with a trailing edge (58), and each cover plate includes at least one conduit (120, 126) for drawing leakage air from a plenum (102) in front of the disk and impinging that air against the platform trailing edges (58) to cool the tailing edges. In the preferred embodiment, each conduit (120) is defined by the rear face of a blade root (40) and a groove (122) cast into the cover plate. The invention makes productive use of leakage air by using that air to cool the platform trailing edges rather than allowing it to flow unbeneficially into the engine gaspath (24) in the vicinity of the platform leading edges (56).

摘要: An airfoil has a body that includes leading and trailing edges joined by spaced apart pressure and suction sides to provide an exterior airfoil surface. A leading edge wall provides the exterior airfoil surface at the leading edge. An impingement wall is integrally formed with the leading edge wall to provide an impingement cavity between the leading edge wall and the impingement wall and multiple impingement holes are provided in the impingement wall. The impingement holes are spaced laterally across the impingement wall. A method of manufacturing an airfoil includes the steps of depositing multiple layers of powdered metal onto one another, joining the layers to one another with reference to CAD data relating to a particular cross-section of an airfoil, and producing the airfoil.
