20090321334 | WASH FILTER WITH WASH VELOCITY CONTROL CONE - A variable wash flow filter assembly includes a wash velocity control cone movable between a minimal position and a maximum position. | 12-31-2009 |
20110289925 | FUEL PUMPING SYSTEM FOR A GAS TURBINE ENGINE - A fuel supply system for a gas turbine engine has a first pump for delivering fuel to a first use on a gas turbine engine, and a second pump for delivering fuel to a second use on the gas turbine engine. A valve allows flow from the first pump to be delivered to the first use, but also routes some flow from the first pump to supplement fuel flow from the second pump until a pressure downstream of the second pump increases. The valve then allows flow from the second pump to flow to the first use to supplement the flow from the first pump. | 12-01-2011 |
20120000844 | WASH FILTER WITH WASH VELOCITY CONTROL CONE - A variable wash flow filter assembly includes a wash velocity control cone movable between a minimal position and a maximum position. | 01-05-2012 |
20120137656 | ACTUATION SYSTEM - A system to provide differential movement between a first surface, a second surface and a fixed surface includes a first surface movable between a first position and a second position; a second surface movable with the first surface and further movable beyond the first surface; a shaft connected to the second surface to move the second surface; and a drive unit connected to the fixed surface to drive the shaft to move the second surface relative to the first surface and to allow the shaft to move through the drive unit when the second surface is being moved by the first surface. | 06-07-2012 |
20120139531 | POSITION DETECTING SYSTEM - A position detecting system for a differential movement system which moves a first surface and a second surface from a fixed surface includes an actuation system to move the second surface relative to the first surface and to allow the second surface to move with the first surface; a sensor connected to the actuation system to detect a parameter of the actuation system related to an expected amount of movement of the second surface to determine the expected amount of movement of the second surface; and a sensor system connected to the second surface and the fixed surface to detect the amount of actual movement of the second surface. | 06-07-2012 |
20120259483 | ACTUATION CONTROL SYSTEM - A dual redundant actuation control system for controlling a plurality of actuators for positioning a plurality of moveable aircraft components. The actuation control system includes a component controller. The component controller includes two component control channels. Each of the plurality of actuators is electrically connected to each of the two component control channels such that either of the two component control channels may control any or all of the plurality of actuators. | 10-11-2012 |
20130008145 | INTEGRATED ELECTRIC VARIABLE AREA FAN NOZZLE THRUST REVERSAL ACTUATION SYSTEM - An integrated variable area fan nozzle (VAFN) and thrust reversing actuation system (TRAS) system includes movable surfaces for adjusting an exit area for bypass flow and cowls moved for directing discharge flow in a reverser manner. The movable surfaces of the VAFN and TRAS systems are both coupled for movement by a common actuator arrangement. A power drive unit drives each of the actuators on each of the actuators through a gearbox or other linkage such that one common motor or motor combination is utilized for driving all of the actuators. A series of redundant and separately actuateable locks control deployment of the surfaces of the thrust reverse system such that thrust reversing system can move to an open or deployed position only in response to each of the locks being actuated to an unlocked condition. | 01-10-2013 |
20130255270 | PASSIVE EQUILIZATION FLOW DIVIDER VALVE - A method and system for providing fuel to primary and secondary fuel nozzles in a gas turbine engine fuel system comprises generating a fuel flow and routing primary fuel from the fuel flow to a primary fuel nozzle. Backpressure on the fuel flow is maintained using a valve. The valve is opened at increased fuel flow to route secondary fuel from the fuel flow to a secondary fuel nozzle. The valve is progressively opened under increasing fuel flows to reduce a pressure drop across the valve produced by the secondary fuel. | 10-03-2013 |
