More Information
Summary:A component for a gas turbine engine includes an airfoil having a plurality of channels with a main body extending between a leading edge and a trailing edge. The main body forms a portion of one side of the airfoil and the entirety of an opposing side of the airfoil. A cover is secured to the main body about a perimeter by a weld. The cover extends across a majority of the one side of the airfoil. A plurality of ribs extends from the cover in a direction toward the main body to define the channels. The ribs are secured to an inner surface of the main body by an adhesive. A gas turbine engine and a method are also disclosed.
