  • High efficiency split flow turbine for compressible fluids
    Patent number: 4165949
    Abstract: In a turbine for a compressible fluid in which the fluid flow leaving the tepenultimate stage is separated into two coaxial flows, the inner flow passes through both the penultimate and the final stages of the turbine while the outer flow passes through the final stage only. This high efficiency arrangement for the last stages of a high power turbine exploits the advantages made available by using titanium as the blade material.

  • Turbine rotor
    Patent number: 4083655
    Abstract: A turbine rotor having twisted blades, are, in the vicinity of their radiy outer portions integrally connected with each other to prevent any rotation in either direction of one blade in relation to its neighboring blades. The blades are prestressed during assembly by being un-twisted through an angle which is less than or equal to and in the same direction as the angle through which said blades would be un-twisted during rotation if they were free to rotate in relation to each other.

  • Turbine shaft having inserted disks
    Patent number: 4029437
    Abstract: The invention concerns a turbine shaft having stepped bearings on which ds are shrunk on. It is characterized in that the connecting surface between two successive bearings consists of two conical portions separated by a cylindrical portion and toroidal connecting portions between the cylindrical portion and the conical portions. The invention reduces the concentrations of stresses and applies more particularly to elastic fluid turbine shafts.

  • Fixing arrangement for a guide part of a fixed casing on a rotating machine
    Patent number: 4027998
    Abstract: A fixing arrangement for a guide part of a fixed casing on a rotating mace whose rotor is supported by a concrete beam, is characterized in that the guide part is fixed to a plate applied against a lateral wall of the beam and is integral with trusses sunk in the mass of the beam. The invention applies, more particularly, to steam turbine exhaust chambers.

  • Continuous connection device for the mobile blades of a turbo-machine
    Patent number: 3981615
    Abstract: Continuous connection device for the mobile turbine blades of a turbo-mace, characterized in that the caps of the turbine blades comprise recesses accomodating clamping blades whose ends press against the neighbouring caps, becoming deformed elastically. The invention applies more particularly to elastic fluid turbines.
