Abstract
A rotating airfoil including a body and a vibration absorber located within the body. The body has a root end and a tip. The rotating airfoil has a natural frequency, and the vibration absorber has a natural frequency. The natural frequency of the vibration absorber is different than the natural frequency of the rotating airfoil.
Claims8
A rotating airfoil comprising:
- a body having a root end and a tip;
- a vibration absorber comprising an adjustable mass and an actuator coupled to the adjustable mass, the adjustable mass located within the body and a radial position of the adjustable mass being actively adjustable towards each of the root end and the tip of the body by the actuator;
- and
- a controller being operatively coupled to the actuator, and the controller being programmed to operate the actuator to selectively adjust the radial position of the adjustable mass based on an input to adjust the natural frequency of the vibration absorber.
