Patent number: 10539032Abstract: A turbomachine includes a plurality of nozzles, and each nozzle has an airfoil. The turbomachine has opposing walls defining a pathway into which a fluid flow is receivable to flow through the pathway. A throat distribution is measured at a narrowest region in the pathway between adjacent nozzles, at which adjacent nozzles extend across the pathway between the opposing walls to aerodynamically interact with the fluid flow. The airfoil defines the throat distribution, and the throat distribution is defined by values set forth in Table 1, where the throat distribution values are within a +/?10% tolerance of the values set forth in Table 1. The throat distribution reduces aerodynamic loss and improves aerodynamic loading on each airfoil.Type: GrantFiled: December 8, 2016Date of Patent: January 21, 2020Assignee: General Electric CompanyInventors: Sumeet Soni, Rohit Chouhan, Ross James Gustafson, Matthew Peter Scoffone

Patent number: 10132195Abstract: Cooling air extracted from a gas turbine engine compressor is sent to nozzle vane cooling passage inlets, through the cooling passages, and to purge tubes of a set of two or more vanes. A mixing chamber formed between the purge tubes in a diaphragm cavity receives fluid from the purge tubes and directs it through exit passage(s) formed through a wall of the mixing chamber to a surface of the diaphragm. The exit passage(s) can be inclined to induce a fluid velocity component substantially parallel to the surface and/or in a rotation direction of a turbine wheel.Type: GrantFiled: October 20, 2015Date of Patent: November 20, 2018Assignee: GENERAL ELECTRIC COMPANYInventors: Matthew Peter Scoffone, Jason Edward Albert, Michael Robert Berry, Mitchell Allan Merrill

Patent number: 10125632Abstract: Cooling air extracted from a gas turbine engine compressor is sent to a nozzle vane cooling passage inlet, through the cooling passage, and to a purge tube of the vane. A mixing chamber formed in a diaphragm cavity receives fluid from the purge tube and directs it through exit passage(s) formed through a side wall of the mixing chamber and/or diaphragm cavity to a diametral surface of the diaphragm. The exit passage(s) can be inclined to induce a fluid velocity component substantially parallel to the diametral surface and/or in a rotation direction of a turbine wheel adjacent the diaphragm.Type: GrantFiled: October 20, 2015Date of Patent: November 13, 2018Assignee: General Electric CompanyInventors: Matthew Peter Scoffone, Jason Edward Albert, Michael Robert Berry, Mitchell Allan Merrill

Patent number: 10031331Abstract: A valve body in a passage of a housing connected to a through hole in a sealed machine casing can allow an inspection apparatus into an interior of the casing when open, and prevents fluid flow through the passage when closed. Seals can engage the inspection apparatus to prevent fluid flow through the passage during inspection or inspection apparatus movement. A guide conduit in the casing can include branches and can guide the inspection apparatus to multiple inspection sites. Guide marks can identify the branches to assist with navigation within the casing.Type: GrantFiled: July 9, 2013Date of Patent: July 24, 2018Assignee: General Electric CompanyInventors: Daniel Lawrence Banowetz, Jordan Christopher Baker, Thomas James Batzinger, Anthony James George, Ronald Irving Longwell, Matthew Peter Scoffone, Daniel David Soloway

Patent number: 9970299Abstract: The present application provides a purge flow delivery system that may be used with a gas turbine engine. The purge flow delivery system may include a mixing chamber with a first sidewall, a second sidewall, and a cover plate, a first inlet tube positioned about the first sidewall, the first inlet tube configured to deliver a first fluid to the mixing chamber, a second inlet tube positioned about the second sidewall, the second inlet tube configured to deliver a second fluid to the mixing chamber, and a baffle plate attached to the cover plate and positioned to direct the first fluid at a first angle and the second fluid at a second angle.Type: GrantFiled: September 16, 2015Date of Patent: May 15, 2018Assignee: GENERAL ELECTRIC COMPANYInventors: Matthew Peter Scoffone, Jason Edward Albert, Mitchell Merrill
