  • Reduced stress rotor interface
    Patent number: 10125785
    Abstract: A bladed rotor and a hub rotor for a gas turbine are provided. A bladed rotor may comprise a rotor interface comprising a radially inward surface, wherein the rotor interface comprises a constant diameter zone; and a reduced stress zone located adjacent to and aft of the constant diameter zone. A hub rotor may comprise a hub interface comprising a radially outward surface, wherein the hub interface comprises, a constant diameter zone, and a reduced stress zone located adjacent to and aft of the constant diameter zone.

  • RIM FACE SCALLOP FOR INTEGRALLY BLADED ROTOR DISK
    Publication number: 20170211398
    Abstract: An integrally bladed disk is provided. The integrally bladed disk includes a rotor disk having a rim with a rim face and a flow path surface perpendicular to the rim face and integrally formed airfoils circumferentially spaced and extending radially outward from the rim, the flow path surface between adjacent integrally formed airfoils, each integrally formed airfoil having an airfoil edge. The rim face includes at least one first surface and at least one second surface formed in the rim face, the at least one first surface being substantially planar and axially proximal to the airfoil edge and the at least one second surface extending an axial depth into the rim face relative to the first surface.

  • FLOW PATH TRENCHES AND METHODS OF FORMING THE SAME
    Publication number: 20170089202
    Abstract: A method of forming a flow path trench in an integrally bladed disk is provided. The method includes tilting a cutting tool relative to a plane defined by the integrally bladed disk, driving the cutting tool at a cutting speed, and moving the cutting tool in a multiple dimensional movement to cut a flow path trench in a surface of the integrally bladed disk.
