  • Patent number: 8038388
    Abstract: A gas turbine engine component includes an airfoil having a radial outward end and a radial inward end. A seal member is positioned adjacent to the radial inward end of the airfoil. A tip of the radial inward end of the airfoil is coated with an abradable material. The seal member is coated with an abrasive material.
    Type: Grant
    Filed: March 5, 2007
    Date of Patent: October 18, 2011
    Assignee: United Technologies Corporation
    Inventors: Melvin Freling, Ken Lagueux, Christopher W. Strock, Joseph G. Pilecki, Jr.
  • Patent number: 7448843
    Abstract: A gas turbine engine is provided with a seal disk that rotates in a closely spaced relationship to a stationary vane. The stationary vane is provided with an abradable tip. The seal disk is provided with alternating portions of a relatively insulating material and a relatively abrasive material. The insulating material can assist the seal disk in resisting thermal expansion. The abrasive material abrades the abradable tip of the stationary vane, ensuring a close, rotating fit.
