Turbine engine airfoil with a scalloped portion

#Turbine engines, and particularly gas or combustion turbine engines, are rotary engines that extract energy from a flow of pressurized combusted gases passing through the engine onto rotating turbine blades.

#Turbine engines are often designed to operate at high temperatures to improve engine efficiency. It can be beneficial to provide cooling measures for engine components such as airfoils in the high-temperature environment, where such cooling measures can reduce material wear on these components and provide for increased structural stability during engine operation.

#In one aspect, the disclosure relates to an airfoil for a turbine engine, including an outer wall bounding an interior and defining a pressure side and a suction side extending between a leading edge and a trailing edge to define a chord-wise direction and extending between a root and a tip to define a span-wise direction, a plurality of outlets extending along the outer wall, and a plurality of non-uniform scalloped portions extending along the outer wall, with at least some of the non-uniform scalloped portions interposed between adjacent outlets.

#In the drawings:

#FIG. 1 is a schematic cross-sectional diagram of a turbine engine for an aircraft.

#FIG. 2 is a perspective view of an airfoil that can be utilized in the turbine engine of FIG. 1.

#Aspects of the present disclosure are directed to an airfoil. For the purposes of description, the airfoil will be described in the context of a turbine engine. It will be understood that the disclosure can have general applicability for any airfoil, including a rotating or non-rotating airfoil, as well as for an airfoil located anywhere within a turbine engine, including in a turbine section or compressor section. The disclosure can also have general applicability in non-airfoil engine components, as well as in non-aircraft applications, such as other mobile applications and non-mobile industrial, commercial, and residential applications.

#As used herein, the term “forward” or “upstream” refers to moving in a direction toward the engine inlet, or a component being relatively closer to the engine inlet as compared to another component. The term “aft” or “downstream” used in conjunction with “forward” or “upstream” refers to a direction toward the rear or outlet of the engine or being relatively closer to the engine outlet as compared to another component.

#As used herein, “a set” can include any number of the respectively described elements, including only one element. Additionally, the terms “radial” or “radially” as used herein refer to a dimension extending between a center longitudinal axis of the engine and an outer engine circumference.
