  • Turbomachine blade
    Patent number: 10982551
    Abstract: A turbomachine airfoil element has an airfoil. The airfoil has an inboard end, an outboard end, a leading edge, a trailing edge, a pressure side, and a suction side. A span between the inboard and an outboard end is 1.4-1.6 inch. A chord length at 50% span is 0.9-1.4 inch. The element is remanufactured by providing first, second, third, fourth, and fifth mode resonance frequencies respectively of 2591.5±10% Hz, 4675.2±10% Hz, 7892.9±10% Hz, 10098.2±10% Hz, and 14808.2±10% Hz.
    Type: Grant
