Abstract:
1. A fastener device for fastening a free turbine stator on a gas generator casing that shares a common axis with the turbine stator, the fastener device comprising: a flange carrying a plurality of assembly parts providing a first releasable connection between said turbine stator and said gas generator casing, said flange providing first centering of the turbine stator on the gas generator casing; and a second releasable connection between said turbine stator and said gas generator casing that is axially offset from the flange towards said gas generator and that provides second centering of said turbine stator on said casing, said second connection being a sliding joint, wherein said second connection is constituted by an axial end of an extender element that extends from said flange in an axial direction, and that is in sliding contact with said gas generator casing.
