摘要: An airfoil assembly has a platform and an airfoil. The platform has an upstream edge, a downstream edge, and a surface extending between the upstream edge and the downstream edge. At least a portion of the surface extends circumferentially along a surface baseline defined by a constant radial distance from the rotational axis. The airfoil has an outer wall. The outer wall extends between a root and a tip, and between a leading edge and a trialing edge. The airfoil assembly includes a fence provided along the outer wall.

摘要: An airfoil assembly for a turbine engine comprising an outer band, an inner band radially spaced inwardly from the outer band to define an annular region, and multiple airfoils circumferentially spaced within the annular region. Each corresponding airfoil of the multiple airfoils can project from a surface at a root and can further include an outer wall defining a pressure side and a suction side. A projection can extend upwardly from the surface on the pressure side and a valley can extend into the surface on the suction side to define a contour in the surface.

摘要: A gas turbine engine comprising a set of circumferentially adjacent airfoils, the airfoils having an outer wall defining a pressure side and a suction side extending between a leading edge and a trailing edge to define a stream-wise direction, and between a root and a tip to define a span-wise direction, and a set of dimples provide on the outer wall of at least one of the airfoils, the set of dimples spaced in at least one of the stream-wise or span-wise directions.

摘要: A wind blade is provided. The wind blade includes a body having an aerodynamic contour extended between a blade root and a blade tip. The wind blade also includes an extension tip sleeve arranged over the blade tip. The extension tip sleeve further includes a first portion having an extension blade and one or more structural ribs arranged on a pressure side of the wind blade. The extension tip sleeve also includes a second portion having a support structure located on a suction side of the wind blade. Furthermore, the wind blade includes a fairing having an airfoil shape for covering the one or more structural ribs, and the support structure of the extension tip sleeve.
