Patent number: 11873758Abstract: An apparatus is provided for a gas turbine engine. This apparatus includes a vane array and a heat exchanger integrated with the vane array. The vane array includes an inner platform, an outer platform and a plurality of vanes. The inner platform extends circumferentially about a centerline and forms an inner peripheral boundary of a flowpath through the vane array. The outer platform extends circumferentially about the centerline and forms an outer peripheral boundary of the flowpath through the vane array. The vanes extend across the flowpath between the inner platform and the outer platform. The heat exchanger includes a passage following a tortuous trajectory along a first wall of the vane array.Type: GrantFiled: October 28, 2022Date of Patent: January 16, 2024Assignee: PRATT & WHITNEY CANADA CORP.Inventors: Eric S. Durocher, Gabriel Naccache

Patent number: 11530645Abstract: A fluid cooler for a gas turbine engine comprises an outer tube having an outer tube inlet at a first end of the fluid cooler and an outer tube outlet at a second end of the fluid cooler. A primary axis of the fluid cooler is defined within the outer tube between the first and second ends of the fluid cooler. A plurality of inner tubes extend within the outer tube between the first second ends of the fluid cooler. The inner tubes have a common inner tube inlet and a common inner tube outlet. The inner tubes extend helically about the primary axis. A first group of the inner tubes are disposed at a first radius from the primary axis and a second group of the inner tubes are disposed at a second radius from the primary axis, the second radius different from the first radius.Type: GrantFiled: February 17, 2021Date of Patent: December 20, 2022Assignee: PRATT & WHITNEY CANADA CORP.Inventors: Constantin Nicolinco, Gabriel Naccache

Patent number: 11525371Abstract: Cooling a torque probe involves an elongated sleeve extending along a sleeve axis between a first sleeve end and a second sleeve end. The sleeve is mountable about the torque probe to define a flow passage between an inner surface of the sleeve and an outer surface of the torque probe. The flow passage is in fluid communication with a flow passage inlet of the sleeve and with a flow passage outlet of the sleeve spaced apart along the sleeve axis from the flow passage inlet. A cooling airflow is configured to flow into the flow passage via the flow passage inlet, through the flow passage along the outer surface of the torque probe to cool the torque probe, and out of the flow passage via the flow passage outlet.Type: GrantFiled: February 2, 2021Date of Patent: December 13, 2022Assignee: PRATT & WHITNEY CANADA CORP.Inventors: Hervé Turcotte, Gabriel Naccache, Adam Logan
