Abstract
A component for a gas turbine engine having an engine axis includes a rotor disk and a plurality of airfoils. The rotor disk comprises a web and a rim. The web has a first outer surface at least partially defining a plurality of holes and a plurality of slots. Each of the plurality of slots extends from a corresponding one of the plurality of holes and forms a first angle with the engine axis at the point of intersection with the corresponding one of the plurality of holes. The rim has a second outer surface also at least partially defining the plurality of slots. Each of the plurality of slots forms a second angle with the engine axis at the second outer surface, the second angle being different from the first angle. Each of the plurality of airfoils extends from the second outer surface.
