Patent number: 10906100Abstract: A method for manufacturing and heat treating a component formed from an alloy or superalloy. The component may be part of a gas turbine engine, such as an airfoil of a gas turbine engine turbine, or a combustor fuel nozzle, that includes internal cooling passages. At least part of the component is formed from the alloy or superalloy using an additive manufacturing process. The method includes determining an incipient melting point range and a recrystallization temperature of the alloy or superalloy. The component is then heated to at least the recrystallization temperature and within the incipient melting point range for a predetermined time, and ultimately cooled.Type: GrantFiled: August 1, 2018Date of Patent: February 2, 2021Assignee: POWER SYSTEMS MFG., LLCInventors: Gregory Edwin Vogel, Jeremy Metternich, Edwin John Kawecki, Jacob Snyder

Patent number: 8752736Abstract: The present invention relates to a self actuating rotary dust valve particularly for discharging dust from an engine air cleaner. The rotary dust valve includes a valve body having an inlet port, an outlet port and a rotor chamber interposed therebetween. A rotary dust ejection member is enclosed in the rotor chamber and supported for rotation about a fixed axis. A plurality of fin members are provided angularly spaced about and secured to the hub member. Adjacent pairs of the fin members define at least one dust pocket therebetween to receive dust from the air cleaner to be ejected. The rotor chamber and the fin members are cooperatively shaped and configured to maintain a continuous air lock closure. The dust valve is operable by any of: gravity and vibration to rotate and thereby to discharge the dust buildup through the outlet port or alternately by other drive means.Type: GrantFiled: July 13, 2010Date of Patent: June 17, 2014Assignee: Mann+Hummel GmbHInventors: Kevin Brian Babb, Jeremy Metternich

Publication number: 20140090396Abstract: The present invention discloses a novel apparatus and method for a mixing fuel and air in a gas turbine combustion system. The mixer helps to mix fuel and air while being able to selectively increase the fuel flow to a shear to a shear layer of a pilot flame in order to reduce polluting emissions. The mixer directs a flow of air radially inward into the combustion system and includes two sets of fuel injectors within each radially-oriented vane. A first plurality of fuel injectors operate independent of a second plurality of fuel injectors and the second plurality of fuel injectors are positioned to selectively modulate the fuel flow to the shear layer of the resulting pilot flame.Type: ApplicationFiled: September 26, 2013Publication date: April 3, 2014Inventors: PETER JOHN STUTTAFORD, STEPHEN JORGENSEN, YAN CHEN, HANY RIZKALLA, KHALID OUMEJJOUD, JEREMY METTERNICH
