Patent number: 10208628Abstract: A turbine engine incorporating a fine particle separation means includes a radial compressor that rotates about a longitudinal axis, a radially-oriented diffuser located downstream and radially outward, with respect to the longitudinal axis, from the radial compressor, and a flow path positioned downstream and radially outward, with respect to the longitudinal axis, from the diffuser, wherein the flow path comprises an outer annular wall and an inner annular wall between which the compressed air flows, and wherein the flow path comprises an arc the redirects the compressed air from flowing in a substantially radial flow direction to a substantially axial flow direction. The turbine engine further includes an extraction slot in the outer annular wall that fluidly connects with a scavenge plenum, the scavenge plenum being positioned adjacent to and radially outward from the outer annular wall at a position downstream axially along the flow path from the arc.Type: GrantFiled: March 30, 2016Date of Patent: February 19, 2019Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Shakeel Nasir, John Schugardt, Nick Nolcheff, John Meier, Yogendra Yogi Sheoran, Shezan Kanjiyani, Daniel Aukland

Patent number: 9970307Abstract: Embodiments of a turbine nozzle having slip joints impregnated by an oxidation-resistant sealing material are provided, as are embodiments of methods for the manufacture of turbine nozzles. In one embodiment, the method includes providing a support ring, a slip joint ring substantially concentric with the support ring and radially spaced apart therefrom, and a plurality of vanes fixedly coupled to the support ring. The plurality of vanes extends radially from the support ring into a plurality of circumferentially-spaced slots provided in the slip joint ring to form a plurality of slip joints therewith. The plurality of slip joints are impregnated with a silicon-modified aluminide sealing material. The silicon-modified aluminide sealing material impedes gas flow into the radial slip joints during operation of the turbine nozzle, while also fracturing to permit relative radial movement between the plurality of vanes and the slip joint ring along the plurality of slip joints.Type: GrantFiled: March 19, 2014Date of Patent: May 15, 2018Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Shezan Kanjiyani, Bradley Reed Tucker, Natalie Wali, Daniel Hicks, Bill Macelroy

Patent number: 9885245Abstract: Turbine nozzles and cooling systems for cooling slip joints therein are provided. The turbine nozzle has an endwall, a vane coupled to the endwall, a slip joint, and a plurality of airfoil quenching holes that cooperate with a plurality of endwall cooling holes. The vane comprises a leading edge and a trailing edge interconnected by a pressure sidewall and a suction sidewall and an end portion. The slip joint is between the end portion and the endwall. The airfoil quenching holes are defined through the pressure sidewall in the end portion. The endwall cooling holes are defined through the endwall along the pressure sidewall and in proximity to the leading edge. The airfoil quenching holes and endwall cooling holes are disposed adjacent the slip joint.Type: GrantFiled: May 20, 2014Date of Patent: February 6, 2018Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Lorenzo Crosatti, Ardeshir Riahi, Bradley Reed Tucker, Shezan Kanjiyani

Patent number: 9611748Abstract: Stationary airfoils configured to form an improved slip joint in bi-cast turbine engine components and the turbine engine components including the same are provided. The stationary airfoil for a bi-cast turbine engine component comprises a leading edge and a trailing edge interconnected by a pressure sidewall and a suction sidewall. An end portion is shaped with a pair of opposing flanges to form a slip joint with a shroud ring in the bi-cast turbine engine component and to define an interlocking feature. The slip joint permits radial movement of the stationary airfoil relative to the shroud ring due to thermal differential expansion and contraction.Type: GrantFiled: December 6, 2013Date of Patent: April 4, 2017Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Harry Lester Kington, Shezan Kanjiyani, Natalie Wali, John Gintert, Bradley R.
