Abstract
Methods and apparatus to reduce deflection of an airfoil are disclosed. An example apparatus disclosed herein includes a plate including an aperture, the airfoil disposed in the aperture, and a damper operatively coupled between the plate and a hub of the airfoil, the damper to transform flexural deflection of the airfoil to radial deflection of the plate.
Claims20
An apparatus to reduce deflection of an airfoil, the apparatus comprising:
- a plate integral to the airfoil, the plate spaced apart in a radial direction from a hub of the airfoil, the airfoil rotatable about a central axis of the airfoil by at least one actuator operatively coupled to the airfoil, the central axis extending in the radial direction;
- and
- a damper operatively coupled between the plate and the hub, the airfoil separate from the hub, the damper to transform flexural deflection of the airfoil to radial deflection of the plate.
An apparatus to reduce deflection of an airfoil, the apparatus comprising:
- a plate welded to the airfoil, the plate spaced apart in a radial direction from a hub of the airfoil, the airfoil rotatable about a central axis of the airfoil by at least one actuator operatively coupled to the airfoil, the central axis extending in the radial direction;
- and
- a damper operatively coupled between the plate and the hub, the airfoil separate from the hub, the damper to transform flexural deflection of the airfoil to radial deflection of the plate.
A gas turbine comprising:
- an airfoil;
- a plate integral to the airfoil, the plate spaced apart in a radial direction from a hub of the airfoil, the airfoil rotatable about a central axis of the airfoil by at least one actuator operatively coupled to the airfoil, the central axis extending in the radial direction;
- and
- a damper operatively coupled between the plate and the hub, the airfoil separate from the hub, the damper to transform flexural deflection of the airfoil to radial deflection of the plate.
