Patent number: 11572789Abstract: A turbine blade for a gas turbine engine has an airfoil including leading and trailing edges joined by spaced-apart pressure and suction sides to provide an external airfoil surface extending from a platform in a spanwise direction to a tip. The external airfoil surface is formed in substantial conformance with multiple cross-sectional profiles of the airfoil defined by a set of Cartesian coordinates set forth in Table 1, the Cartesian coordinates provided by an axial coordinate scaled by a local axial chord, a circumferential coordinate scaled by a local axial chord, and a span location.Type: GrantFiled: November 11, 2021Date of Patent: February 7, 2023Assignee: PRATT & WHITNEY CANADA CORP.Inventors: Constantinos Ravanis, Vincent Paradis, Eduardo Hawie, Michael Papple, Marc-Antoine Mailloux-Labrousse, Othmane Leghzaouni, Philippe Boyer, Jasrobin Grewal

Patent number: 11306593Abstract: A gas turbine engine comprising: a shaft about an axis; a first turbine assembly mounted to the shaft, a first flow path and a second flow path extending through first turbine assembly along the axis. The second flow path is located radially inward of the first flow path relative to the axis. A second turbine assembly is about the axis downstream of the first turbine assembly, with a gap defined between the first turbine assembly and the second turbine assembly, the gap in fluid communication with the first flow path and the second flow path. A washer is downstream of the first turbine assembly.

Patent number: 11193380Abstract: An integrated strut and turbine vane nozzle (ISV) has inner and outer annular duct walls defining an annular flow passage therebetween. Circumferentially spaced-apart struts extend radially across the flow passage. Circumferentially spaced-apart vanes also extend radially across the flow passage and define a plurality of inter-vane passages. Each of the struts is integrated to an associated one of the vanes to form therewith an integrated strut-vane airfoil. The inter-vane passages on either side of the integrated strut-vane airfoil may be adjusted for aerodynamic considerations. The vanes may be made separately from the struts and manufactured such as to cater for potential misalignments between the parts.Type: GrantFiled: January 21, 2019Date of Patent: December 7, 2021Assignee: PRATT & WHITNEY CANADA CORP.Inventors: Vincent Paradis, Edward Vlasic, Panagiota Tsifourdaris
