  • Integrated strut and vane arrangements
    Patent number: 10221711
    Abstract: In an integrated strut and turbine vane nozzle (ISV) configuration, lug/slot or tag/groove arrangements may be provided between an interturbine duct (ITD) of the ISV and a vane ring of the ISV such that struts of the ITD and associated vanes are angularly positioned to form integrated strut-vane airfoils, reducing mismatch at the integration.
    Type: Grant
    Filed: October 30, 2017
    Date of Patent: March 5, 2019
    Assignee: PRATT & WHITNEY CANADA CORP.
    Inventors: Vincent Paradis, John Walter Pietrobon, Richard L. Bouchard
