20100270242 | COMBINED OIL FILTER AND DEBRIS MONITOR - A cyclone separator includes a wall, a first passage, a second passage, and an oil debris monitor. The wall defines a cyclone cavity. The first passage has a first passage inlet positioned in the cyclone cavity and a first passage outlet at an exterior of the cyclone separator. The second passage has a second passage inlet positioned in the cyclone cavity and a second passage outlet at the first passage. The oil debris monitor detects debris flowing through the second passage. | 10-28-2010 |
20110012592 | MAGNETIC FLUX OIL LEVEL SENSOR FOR USE IN AIRCRAFT LUBRICATION SYSTEMS - A magnetic flux position sensor includes a primary coil, a secondary coil, and a magnetic flux conductor. The primary coil generates a magnetic flux and the secondary coil senses magnetic flux. The primary and secondary coils are substantially concentric and spaced apart by an annular passage. The annular passage has first and second ends, and the magnetic flux conductor is slidable from the first end to the second end of the annular passage. The magnetic flux transferred from the primary coil to the secondary coil varies as a function of position of the magnetic flux conductor. | 01-20-2011 |
20120073301 | CRITICAL FLOW NOZZLE FOR CONTROLLING FUEL DISTRIBUTION AND BURNER STABILITY - A fuel delivery system for delivering fuel to a gas turbine engine includes a fixed critical flow nozzle, a first fuel nozzle and a second fuel nozzle. The fixed critical flow nozzle and the variable critical flow nozzle are connected to a fuel source in parallel. The fixed critical flow nozzle has an orifice throat with a fixed effective cross-sectional area. The variable critical flow nozzle has an orifice throat with a variable effective cross-sectional area. The first fuel nozzle is connected to the fixed critical flow nozzle for delivering fuel to the gas turbine engine, and the second fuel nozzle is connected to the variable critical flow nozzle for delivering fuel to the gas turbine engine. | 03-29-2012 |
20120227409 | AIRCRAFT FUEL SYSTEM COOLING FLOW DEVICE - A cooling system includes a housing having an aperture intersecting a passage that includes first and second passage portions. A plug is arranged in the aperture in an interference fit in a first position at a first temperature condition to block the passage and fluidly separate the first and second passage portions. A biasing element is arranged in the housing and is configured to move the plug from the first position to a second position at a second temperature condition to fluidly connect the first and second passage portions. | 09-13-2012 |
20130055723 | Apparatus and Method for Separating Ice from Fuel in a Gas Turbine Engine - According to one aspect of the invention, an ice separating apparatus for a gas turbine engine includes a can having a first end and a tangential inlet proximate the first end of the can to receive a fluid flow within the can, wherein the fluid flow includes fuel and ice. The apparatus also includes a first conduit within the can to receive a separated fuel flow proximate a second end of the can, wherein the fluid flow separates ice from fuel to form the separated fuel flow. | 03-07-2013 |
20130186098 | FLUID FLOW CONTROL DEVICE AND METHOD - A fluid flow control system includes a fluid inlet, a central chamber, a first nozzle extending from a first side of the central chamber and comprising a first throat, a second nozzle extending from a second side of the central chamber opposite the first side and comprising a second throat, and a flow control shuttle. The flow control shuttle includes a first needle having a first tapered portion positioned within the first throat for controlling flow through the first nozzle and a second needle having a second tapered portion positioned within the second throat for controlling flow through the second nozzle. | 07-25-2013 |
20130197828 | FLUID MASS FLOW MEASUREMENT APPARATUS AND METHOD - A meter controller comprises a first input, a second input, and a processor. The processor is configured to receive first and second volumetric flow measurements and to calculate a quasi fluid density value required to cause the first volumetric flow measurement to equal the second volumetric flow measurement. The processor is further configured to subtract a first fluid density value from the quasi fluid density value for calculating a density correction factor. The density correction factor is subtracted from the first fluid density value to calculate a corrected second density value. The corrected second density value is applied to at least one of the first volumetric flow measurement and the second volumetric flow measurement for calculating a mass flow rate measurement. | 08-01-2013 |
20140332703 | ADJUSTMENT AND LOCKING MECHANISMS - A locking mechanism includes a connection portion, a first arm, a second arm, and a fastener. The first arm extends from the connection portion and defines a first aperture and a second aperture. The second arm extends from the connection portion and defines a third aperture. The first arm is spaced from the second arm by a notch. The fastener is adapted to extend through the first aperture and across the notch to abut the second arm. | 11-13-2014 |
