Patent ID: 10711613

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 2.58-2.88 inch (65.4-73.1 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 1.59-1.89 inch (40.3-48.0 mm). The airfoil element includes at least two of a first mode with a frequency of 2088±10% Hz, a second mode with a frequency of 3099±10% Hz, a third mode with a frequency of 6890±10% Hz, a fourth mode with a frequency of 7207±10% Hz, a fifth mode with a frequency of 11241±10% Hz, a sixth mode with a frequency of 11916±10% Hz and a seventh mode with a frequency of 12600±10% Hz.
