Abstract
An airfoil includes an airfoil structure defining a damping network that includes a first cavity, a second cavity, a flow passage connecting the first and second cavities. The airfoil further includes a damping material configured to flow through the damping network. A method of forming an airfoil includes forming an airfoil body having a damping network that includes a first cavity, a second cavity, and a flow passage connecting the first and second cavities. The method further includes adding a damping material configured to flow through the damping network.
Claims12
An airfoil comprising:
- an airfoil structure defining a damping network that includes a first cavity, a second cavity, and a first flow passage connecting the first and second cavities, a second flow passage connecting the first and second cavities, and a third flow passage connecting the first flow passage and the second flow passage;
- and
- a damping material configured to flow through the damping network.
A method of forming an airfoil, the method comprising:
- forming an airfoil body having a damping network that includes a first cavity, a second cavity, and a flow passage connecting the first and second cavities, and forming at least one fill passage for adding the damping material to the damping network;
- and
- adding a damping material configured to flow through the damping network.
