Integrated strut and vane arrangements

摘要

In an integrated strut and turbine vane nozzle (ISV) configuration (28), a lug/slot arrangement (46) or a tag/groove arrangement is provided between an interturbine duct (ITD) of the ISV and a vane ring of the ISV such that struts (34) of the ITD and associated vanes (44) are angularly positioned to form integrated strut-vane airfoils, reducing mismatch at the integration.
