Patent number: 9551291Abstract: Steel pistons used in many internal combustion engines are generally composed of a skirt and a crown. The skirt's function is to reduce the lateral and rotational movement of the piston in the cylinder while the engine is in operation. Lateral and rotational frictional forces imparted to a piston during engine operation cause the piston to scrape off the lubricating oil film present on the cylinder wall. The reduced oil film thickness increases piston and cylinder wall wear due to metal to metal contact. The subsequent metal to metal contact produces a phenomenon called scuffing. This disclosure incorporates several design modifications to the piston and results in a significant reduction of the lateral and rotational motion of the piston during engine operation. The reduction of piston motion reduces the amount of oil film removed from the cylinder wall and increases lubrication efficiency. The Increased lubrication efficiency realized reduces frictional wear power loss and scuffing.Type: GrantFiled: January 28, 2014Date of Patent: January 24, 2017Assignee: Mahle International GmbHInventors: Valerian Ioja, Michael T.

Patent number: 9551292Abstract: Engine systems and associated methods, including systems with semi-isothermal compression devices are disclosed. An engine system in accordance with a particular embodiment includes a compressor having a compressor inlet and outlet, a combustor having a combustor inlet coupled to the compressor outlet and further having a combustor outlet, a positive displacement expander having an expander inlet coupled to the combustor outlet, and further having an expander outlet and a work output device. A valve is coupled between the combustor and the expander to regulate a flow of hot combustion products passing from the combustor to the expander, and an exhaust energy recovery device is coupled to the expander outlet to extract energy from the combustion products exiting the expander.Type: GrantFiled: December 19, 2013Date of Patent: January 24, 2017Assignee: Bright Energy Storage Technologies, LLPInventors: Scott R. Frazier, Alex Lau, Brian Von Herzen

Patent number: 9551294Abstract: Tracks (35), fastened to static structure of an aircraft engine nozzle, guide sliders (32) journaled in struts (27, 28) fastened to a flap (23) of the nozzle. Each slider and attached journal axle or bolt (33) is formed of cobalt, and each track slider surface (61) and journal bushings (43, 44) are formed of a nickel alloy to reduce wear from rubbing. Track slides (40, 41) are mounted to the static structure of the nozzle by blind bolts (68) having a tool recess (70) at its threaded tip to prevent the bolt (68) from turning as a nut is secured. Each slider has limited rotation due to a pin (102), thereon engaging a slot in a tab (100) of the bushing (43) to assist in inserting the slider (32) into the beveled ends of the tracks (35, 36), when mounting or replacing a flap.Type: GrantFiled: January 15, 2014Date of Patent: January 24, 2017Assignee: United Technologies CorporationInventors: Joseph J Czapski, Jr., David C Pimenta, Chung-Han Liou, Paul R Senofonte, Steven D.

Patent number: 9551295Abstract: Systems, devices, and methods are presented for detecting a misaligned or otherwise skewed variable area fan nozzle (VAFN) that is mounted on a thrust reverser sleeve of an aircraft engine. Rods project from different parts around the arcuate VAFN, the rods having patterns at their ends. In normal operation when the thrust reverser is stowed, the rods project over the thrust reverser into a fixed area of the engine. Sensors in the fixed area determine the position of the VAFN from the patterns on the rods. When the thrust reverser deploys, the rods are pulled aft with the VAFN, which is mounted on the thrust reverser sleeve, and separate from the sensors. When the thrust reverser stows, the rods move forward with the VAFN and re-engage with the sensors. Repeating patterns on the rods allow for simple, relatively low-cost sensors to read their relative positions.Type: GrantFiled: July 24, 2013Date of Patent: January 24, 2017Assignee: Rohr, Inc.Inventor: Timothy Gormley

Patent number: 9551296Abstract: A thrust vectoring system is created with a convergent-divergent nozzle having a total angle no greater than 150 degrees. A divergent portion of the nozzle has a wall at a predetermined angle of at least 12° from the freestream direction. A disturbance generator is located on the wall to induce flow separation from the wall with the predetermined wall angle sufficient for the induced flow separation to extend upstream from disturbance generator substantially to a throat of the nozzle pressurizing the wall and creating a net vector angle in jet flow through the nozzle.Type: GrantFiled: January 20, 2014Date of Patent: January 24, 2017Assignee: The Boeing CompanyInventors: Chad M. Winkler, Andrew J. Dorgan, Eric L. Werner

Patent number: 9551297Abstract: Reducing jet noise by weakening Mach cones in a jet exhaust gas streamtube. The Mach cones are weakened by modifying exhaust gas flow in a longitudinal axial core of the exhaust gas streamtube.Type: GrantFiled: December 4, 2015Date of Patent: January 24, 2017Assignee: Lockheed Martin CorporationInventors: Neal D. Domel, Daniel N. Miller

Patent number: 9551298Abstract: A nacelle assembly for a turbofan engine includes a forward nacelle portion having an aft edge and defining a bypass duct that transports bypass airflow of the turbofan engine, a translatable sleeve that is translatable aft of the forward nacelle portion, and a variable area fan nozzle (VAFN) airfoil that is movable between a stowed position, a VAFN flow position, and a thrust reverse position. Blocker doors for the thrust position are integrated into the VAFN airfoil.Type: GrantFiled: July 24, 2013Date of Patent: January 24, 2017Assignee: Rohr, Inc.Inventors: Alan Binks, Michael J. Layland, Norman J. James

Patent number: 9551299Abstract: A combustion chamber includes an inner wall, an outer wall surrounding the inner wall, and a flow passage between the inner wall and outer wall that permits forward flow and restricts reverse flow. The inner wall has a plurality of effusion holes in fluid communication with the inside of the combustion chamber. The outer wall has a plurality of cooling side holes in fluid communication with a cooling source. The inner wall and the outer wall define a flow passage therebetween that fluidly connects one or more of the cooling side holes with one or more of the effusion holes. The flow passage has a geometric configuration to permit forward flow of gases through the flow passage from the cooling source to the inside of the combustion chamber and to restrict reverse flow of gases through the flow passage from the inside of the combustion chamber to the cooling source. The permitted flow rate is greater than the restricted flow rate.Type: GrantFiled: March 10, 2014Date of Patent: January 24, 2017Assignees: Rolls-Royce Corporation, Rolls-Royce North American Technologies, Inc.Inventors: James C. Loebig, Christopher D. DeBruhl, John D. Holdcraft
