  • Patent number: 10066492
    Abstract: A turbomachine blade having a metal coupling root, and a metal airfoil-shaped oblong member cantilevered projecting from the coupling root; the airfoil-shaped oblong member being divided into: a lower connecting fin cantilevered projecting from and formed in one piece with the coupling root; an upper connecting fin cantilevered projecting from a coupling head towards the coupling root and formed in one piece with the coupling head; and a main plate-like body which is shaped and positioned between the two connecting fins to form an extension of the fins, and is butt-welded to the same connecting fins to form one piece with the fins.

  • Publication number: 20150226068
    Abstract: A manufacturing process of a lightened blade for turbomachines, comprising the steps of manufacturing a semi-finished product provided with an oblong plate-like portion whose shape substantially approximates the shape of the main airfoil-shaped body of the shaped airfoil of the lightened blade to be built; obtaining, substantially at the centre of one of the two faces of said plate-like portion, at least one hollow seat of predetermined shape; positioning in abutment on the surface of the face of the plate-like portion where the hollow seat is, a covering plate, the dimensions of which exceed those of the hollow seat, so as to cover the surface of the face of the plate-like portion where the hollow seat is, up to the larger lateral edges of the same plate-like portion; fixing in a rigid and unmovable way the covering plate on the face of the plate-like portion by means of an adhesive layer or lap welding that affects the perimeter strip or flap of the covering plate that rests directly on the surface of the f

  • Publication number: 20140237821
    Abstract: A method of producing a turbomachine blade having a coupling root, and an airfoil-shaped oblong member cantilevered from the coupling root; the airfoil-shaped oblong member having a main plate-like element connected directly to the coupling root, and a cover plate for sealing a hollow weight-reducing seat formed in one of the two major faces of the main plate-like element; the main plate-like element being divided into a lower connecting fin cantilevered from the coupling root, and a plate-like body butt welded to the lower connecting fin to form an extension of the lower connecting fin; the method being characterized by including the steps of twisting and curving a flat plate of constant thickness greater than the maximum thickness of the plate-like body of the blade, to obtain a blank plate, in which the three-dimensional shape of the centerline surface of the blank plate substantially matches the three-dimensional shape of the centerline surface of the plate-like body of the main plate-like element.
