  • Method of forming a windage cover for a gas turbine engine the method including forming a continuous ring from a sheet of metal and bending and cutting the continuous ring to form at least two arcuate segments
    Patent number: 8240043
    Abstract: A stator assembly having a windage cover for structure adjacent to a cavity bounded by rotating elements in a rotary machine is disclosed. Various construction details are developed for damping vibrations in the windage cover as the windage cover bounds a cavity having swirling high velocity gases that are capable of transmitting acoustic energy and kinetic energy to adjacent structure. In one detailed embodiment, the windage cover in the uninstalled condition has diverging arms that are resiliently compressed during installation to exert a frictional force on the adjacent structure.
    Type: Grant
    Filed: December 19, 2009
    Date of Patent: August 14, 2012
    Assignee: United Technologies Corporation
    Inventors: Paul W. Duesler, C. Vincent Loffredo, Matthew D. Nicolson, Richard J. Pawlaczyk
