Abstract: An integrally bladed rotor includes a rotor that has a rim that provides an inner flow surface. Circumferentially spaced apart radially extending airfoils integrally with and from the rotor and joined by an airfoil fillet. An asymmetrical trench is provided in the rim between adjacent airfoils.

Abstract: A rotating component for a turbine engine includes a main component portion including a web and a platform located at a radially outboard portion of the web, relative to an axis of rotation of the rotating component. A snap surface is located at the platform and is configured to interlock the rotating component with an adjacent rotating component. A transition surface extends from the main component portion to the snap surface and includes two or more different radii.

Abstract: An integrally bladed rotor includes a rim integral with a web that extends radially inward to a bore. The rim provides an end wall from which integral blades extend radially outward to a tip. The blades have an airfoil that extends in a chord-wise direction from a leading edge to a trailing edge. A fillet circumscribes the airfoil and joins the airfoil to the end wall. The fillet is at one of the leading edge and the trailing edge is truncated at least 50% in an axial direction to provide a face of the rim.

Abstract: A rotor disk includes a web that extends from a rim radially inward to a bore. A spacer is integral with and extending generally axially from the rim. The spacer includes a flow path surface adjacent to an end wall of the rim. An inner surface is spaced radially inwardly from the flow path surface and extends between first and second axial locations. A fillet interconnects the inner surface and the web. The inner surface is tangent to the fillet at the first axial location. The second axial location axially aligns beneath vanes and surrounded by the inner surface. The spacer has first and second radial thicknesses respectively disposed at the first and second axial locations. The first and second radial thicknesses are different than one another. The spacer is at least partially tapering axially between the first and second axial locations.
