  • Publication number: 20120121395
    Abstract: A method for fabricating a gas turbine engine component including an inner ring, an outer ring and at least one strut connecting the inner ring with the outer ring includes the steps of connecting the inner ring to the outer ring via a load carrying edge of the strut, and attaching a side face component of the strut in abutment with the load carrying edge after the step of connecting the inner ring to the outer ring has been performed. A as turbine engine component fat by the method is also provided.

  • Publication number: 20110283711
    Abstract: A gas turbine component includes an element having a relatively weak region with regard to stress loads in operation, the component including at least one elongated stiffening structure which extends on at least one side of the weak region, and the elongated stiffening structure is connected to the element in a load-transmitting manner and adapted to form a load path in its extension direction.

  • Patent number: 7544040
    Abstract: The present invention relates to a support structure and a method for assembling a support structure in a turbine or compressor engine for rotatably supporting a rotor member in a stator member. The support structure includes an inner ring, an outer ring and a plurality of struts which extend radially between the inner ring and the outer ring. The inner ring has integrated portions projecting in the direction of the struts and forming end connections for the struts. The integrated end connecting portions of the inner ring are together with the ring made by a metal alloy having initially oversized cross sectional dimensions relative to the cross sectional dimensions of corresponding strut, followed by working at least one lateral surface for removing material. The purpose is to achieve final dimensions and position to conform to the cross sectional dimensions and correct position of each corresponding strut.
