Patent number: 8733107Abstract: A mechanism included in a convergent-divergent nozzle connected to an aft portion of a gas turbine engine, which mechanism includes a convergent flap configured to be kinematically connected to the aft portion of the gas turbine engine, a divergent flap pivotally connected to the convergent flap and configured to be kinematically connected to the aft portion of the gas turbine engine, at least one actuator configured to be connected to the aft portion of the gas turbine engine and to mechanically prescribe the position of the convergent flap and the divergent flap by moving through one or more positions, and at least one biasing apparatus. The biasing apparatus is configured to position at least one of the convergent flap and the divergent flap independent of the positions of the actuator by substantially balancing a force on the at least one of the convergent flap and the divergent flap produced by a gas pressure on the nozzle.Type: GrantFiled: December 16, 2010Date of Patent: May 27, 2014Assignee: United Technologies CorporationInventors: Timothy A.

Patent number: 7871242Abstract: A rotational flow balance system includes an actuator system which controls operation of both a fan duct blocker ring and a modulated exhaust cooling ring through a kinematic system. The kinematic system is controlled by the single actuator system such that the modulated exhaust cooling ring will remain in a fixed position while the fan duct blocker ring can be moved to satisfy operational requirements.Type: GrantFiled: May 31, 2007Date of Patent: January 18, 2011Assignee: United Technologies CorporationInventors: Timothy A. Swanson, Carl T. Elving, Robert T. Brooks

Publication number: 20080098742Abstract: A balance pressure control is provided for flaps which pivot in a rear of a gas turbine engine nozzle to change the cross-sectional area of the nozzle. An actuator drives a sync ring to move the flaps through a linkage. A supply of pressurized air is also provided to the sync ring to assist the actuator in resisting forces from high pressure gases within the nozzle. When those forces are lower than normal the flow of air to the rear of the sync ring is reduced or blocked. A ring rotates with another ring to control both this air flow, and a supply of cooling air to an interior of the nozzle.Type: ApplicationFiled: October 27, 2006Publication date: May 1, 2008Inventors: Andreas Sadil, Timothy A. Swanson, Roger O. Coffey, Debora F. Kehret

Publication number: 20070226326Abstract: A method of generating a standardized network-management representation of a multiple-layer network communications interface sub-stack having a non-standardized network-management representation includes determining, based on a signature indicating a layered structure of the network communications interface sub-stack, whether an expected type of sub-layer interface of the network communications interface sub-stack exists. If the expected type of sub-layer interface is determined not to exist, then a sub-layer interface of the expected type is created and a network management information base is populated with a sub-layer interface entry including (1) respective instance and type identifiers of the sub-layer interface and (2) one or more operational attributes of the sub-layer interface, the value of each operational attribute identically mirroring the value of a corresponding operational attribute of the interface sub-stack as reflected in the non-standardized network-management representation.Type: ApplicationFiled: March 24, 2006Publication date: September 27, 2007Applicant: Cisco Technology, Inc.Inventors: Patrick Gili, Jaime Colom, Enid Jimenez, Agrahara Koushik, Timothy Swanson, Leon Zachery
