  • Means for inducing vibration in an airfoil
    Patent number: 4019375
    Abstract: An apparatus for inducing vibratory oscillations in an airfoil is provided to simulate the dynamic aeroelastic interaction between the airfoil and a gas flow field. The apparatus includes first means for supporting the airfoil during inducement of the vibrations and second means movable in response to variations in magnetic flux to rotate the airfoil about first and second axes. Third means are provided for generating a variable magnetic flux field in response to an electrical control signal provided by fourth means.
