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 0.75-0.85 inch (19.1-21.6 mm). A chord length extends in a chordwise direction from the leading edge to the trailing edge at 50% span and is in a range of 0.56-0.66 inch (14.2-16.8 mm). The airfoil element includes at least two of a first mode with a frequency of 2740±10% Hz, a second mode with a frequency of 5956±10% Hz, a third mode with a frequency of 6554±10% Hz and a fourth mode with a frequency of 31959±10% Hz.

Abstract: A cantilevered mounted singlet vane includes a first outer shroud and a first airfoil. The first outer shroud is provided with a first body having a first body first side and a first body second side axially extending between a first body first end and a first body second end. The first outer shroud defines a first slot axially extends from the first body first end towards a first body end wall disposed at the second end. The first airfoil radially extends from the first outer shroud.

Abstract: An assembly includes a first vane pack, a second vane pack, and a liner lock segment. The first vane pack has a plurality of vanes each vane with an airfoil, a platform, and forward and aft mounting hooks. The second vane pack has a plurality of vanes each vane with an airfoil, a platform, and forward and aft mounting hooks. The second vane pack is disposed to abut the first vane pack. The liner lock segment is disposed between the first vane pack and the second vane pack.
