  • Structures for attaching or sealing a space between components having different coefficients or rates of thermal expansion
    Patent number: 6910853
    Abstract: A structure for attaching together or sealing a space between a first component and a second component that have different rates or amounts of dimensional change upon being exposed to temperatures other than ambient temperature. The structure comprises a first attachment structure associated with the first component that slidably engages a second attachment structure associated with the second component, thereby allowing for an independent floating movement of the second component relative to the first component. The structure can comprise split rings, laminar rings, or multiple split rings.
    Type: Grant

  • Fixing system of a flame pipe or liner
    Publication number: 20050050902
    Abstract: Fixing system (1), inside the combustion chamber of a gas turbine with low polluting emissions, of a liner or flame pipe equipped with two cylindrical elastic heads (5) each wedged at the end of the flame pipe (10) to allow its thermal expansion by lowering the thermal tensions due to the different expansion coefficient with the combustion chamber.
