Abstract:
A turbomachine airfoil element includes an airfoil that has pressure and suction sides spaced apart from one another in a thickness direction and joined to one another at leading and trailing edges. The airfoil extends in a radial direction a span that is in a range of 0.55-0.65 inch (14.0-16.5 mm). A chord length extends in a chordwise direction from the leading edge to the trailing edge at 50% span is in a range of 0.76-0.86 inch (19.3-21.8 mm). The airfoil element includes at least two of a first mode with a frequency of 3335±10% Hz, a second mode with a frequency of 5715±10% Hz and a third mode with a frequency of 41797±10% Hz.
Abstract:
A vane stage assembly includes an airfoil including a leading edge and a trailing edge. An inner shroud extends from the leading edge to the trailing edge for supporting the airfoil. The shroud includes a forward portion including an axial width and a forward thickness extending in a radial direction. A ratio of the forward radial thickness divided by the forward axial thickness is between 0.64 and 1.11 for defining a natural frequency of the airfoil. A gas turbine engine and method are also disclosed.

Abstract:
A stator vane assembly is provided. The stator vane assembly may comprise a stator vane, an outer shroud, and a spring. A first end of the stator vane may be fixed to an inner diameter (ID) surface of a vane platform. A slot may be disposed in a surface of the outer shroud, wherein a portion of the stator vane is configured to be located within the slot. In various embodiments, the stator vane may be configured to translate in a radial direction in response to a force between the stator vane and a rotor. In various embodiments, the spring may be configured to be coupled to an outer diameter (OD) surface of the vane platform, wherein the spring is configured to bias the ID surface of the vane platform toward the outer shroud.
