Patent number: 12168940Abstract: A turbomachine comprises a primary rotor part and a secondary rotor part mounted to the primary rotor part for joint rotation therewith. The primary part and secondary parts have a tight fit between a radially inner diameter surface of the secondary part and a radially outer diameter surface of the primary part. The primary part has a radial stop operable to limit centrifugal growth of the secondary part when a maximum operating speed of the primary rotor is exceeded. The radial stop includes a radially inner surface facing an associated radially outer surface of the secondary part. When an operating speed of the primary part is inferior to the maximum operating speed, the radial stop of the primary part and the associated radially outer surface of the secondary part are spaced by a radial gap sized to close when the maximum operating speed is exceeded.Type: GrantFiled: September 8, 2023Date of Patent: December 17, 2024Assignee: PRATT & WHITNEY CANADA CORP.Inventor: Thierry Stocco

Patent number: 12168943Abstract: An energy storage system converts variable renewable electricity (VRE) to continuous heat at over 1000° C. Intermittent electrical energy heats a solid medium. Heat from the solid medium is delivered continuously on demand. An array of bricks incorporating internal radiation cavities is directly heated by thermal radiation. The cavities facilitate rapid, uniform heating via reradiation. Heat delivery via flowing gas establishes a thermocline which maintains high outlet temperature throughout discharge. Gas flows through structured pathways within the array, delivering heat which may be used for processes including calcination, hydrogen electrolysis, steam generation, and thermal power generation and cogeneration. Groups of thermal storage arrays may be controlled and operated at high temperatures without thermal runaway via deep-discharge sequencing. Forecast-based control enables continuous, year-round heat supply using current and advance information of weather and VRE availability.Type: GrantFiled: January 4, 2024Date of Patent: December 17, 2024Assignee: Rondo Energy, Inc.Inventors: John Setel O'Donnell, Peter Emery von Behrens, Matthieu Jonemann, Yusef Desjardins Ferhani
