  • Double-walled annular articles and apparatus and method for sizing the same
    Patent number: 6910859
    Abstract: An embodiment of a disclosed apparatus for sizing an engine stator has a plurality of radially moveable shoes for engaging the inner and outer rings of the stator. The shoes apply a radially directed force to the inner and outer rings to cause the rings to expand. In particular embodiments, one or more heating mechanisms, such as a ceramic heating blanket, may be used to heat the stator prior to sizing. A method for sizing an engine stator also is disclosed. The method comprises simultaneously displacing the inner and outer rings of the stator generally radially outwardly so as to increase the respective diameters of the inner and outer rings.
