  • IMPROVED TURBINE AND BLADE FOR THE PROTECTION OF THE ROOT FROM FLOW PATH HOT GASES
    Publication number: 20230082038
    Abstract: A turbine, and particularly a low pressure turbine is disclosed, which comprises a plurality of rotor members and spacers for arranged between rotor members, to avoid that an ingested gas flow from the hot gas flow path channel reaches the wheel space. The rotor members each include a deflector. The deflector is placed in correspondence with each spacer and deflects the ingested gas flow over the upper surface of the spacer, thus preventing it to heat up the roots of the blades.

  • Aircraft engine systems and methods for operating same
    Patent number: 9507342
    Abstract: A device and a method for determining a residual life expectancy of a rotor of a gas turbine. The method includes receiving at a computer operating conditions of the gas turbine, receiving a gas turbine rotor inspection result, updating, based on the operating conditions of the gas turbine and the gas turbine rotor inspection result, a database for a fleet corresponding to the gas turbine, and calculating the residual life expectancy of the rotor of the gas turbine.

  • Method for subsea equipment subject to hydrogen induced stress cracking
    Patent number: 8386221
    Abstract: Systems and methods for generating transfer functions associated with calculating local stresses on pipe elements by post processing forces and moments of a pipe model representing the piping system. The transfer functions are reusable and allow recalculation with different sets of user data without requiring regeneration of the transfer functions.
