Abstract
In accordance with one aspect of the disclosure, a lubricant application device for providing lubricant to an airfoil of a gas turbine engine is disclosed. The device may include a container for holding a lubricant, a fluid outlet in fluid communication with the container, a discharge mechanism controlling a flow of the lubricant from the container to the fluid outlet, and an extension tube in fluid communication with the fluid outlet. When the discharge mechanism is activated the lubricant may flow out of the container and through the extension tube. The extension tube may be dimensioned to fit between an airfoil root and rotor cavity of a gas turbine engine.
Claims9
A method of applying a lubricant to a fully assembled rotor of a gas turbine engine, comprising:
- providing a lubricant application device having a container for holding the lubricant, a fluid outlet in fluid communication with the container, a discharge mechanism controlling the flow of lubricant from the container to the fluid outlet, and an extension tube in fluid communication with the fluid outlet;
- inserting the extension tube into a root cavity formed in a rotor disk of the rotor to accept a root of a blade of the rotor;
- and
- activating the discharge mechanism to release the lubricant from the container and onto the rotor.
