Publication number: 20240072621Abstract: A method of making an electromagnetic coil for use in a high-temperature electromagnetic machine includes pre-coating magnet wire with a high-temperature insulation precursor to produce pre-coated magnet wire, winding, while applying in-situ a glass-ceramic slurry, the pre-coated magnet wire into a predetermined coil shape to produce a wet-wound green coil, and thermally processing the wet-wound green coil to produce a processed coil. In some instances, a second layer of a high-temperature insulation may be applied to the processed coil to produce a further insulated processed coil, and then thermally processing the further insulated processed coil to produce a further processed electromagnetic coil.Type: ApplicationFiled: August 30, 2022Publication date: February 29, 2024Applicant: HONEYWELL INTERNATIONAL INC.Inventors: Mahdi Mohajeri, Eric Passman, Bahram Jadidian, James Piascik, Robert Dietrich, Andre Robinson, Jimmy Wiggins, Tom McHugh, Yongbae Jung

Publication number: 20240011401Abstract: A gas turbine blade for a gas turbine engine includes an attachment, a blade neck portion, a platform, an airfoil, and a shroud. The gas turbine engine has an operating speed range. The blade neck portion extends radially outward from the attachment. The platform is attached to the blade neck portion opposite the attachment. The airfoil extends radially outward from the platform. The airfoil includes a leading edge, a trailing edge, and an axial chord defined between the leading and trailing edges. The axial chord defines a mid-chord point. The shroud is attached to an end of the airfoil. The shroud includes an upper surface and a modal response tuning component attached to the upper surface of the shroud. The modal response tuning component is offset from the mid-chord point a predetermined distance to move modal response of the gas turbine blade outside of the operating speed range.Type: ApplicationFiled: July 11, 2022Publication date: January 11, 2024Inventors: Douglas James Dietrich, Alexander Vasili Rozendaal, Stephen Fiebiger, Alex Torkaman
