The turbine engine assembly includes a stator assembly and a rotor assembly having a rotor disk coupled to a plurality of rotor blades, the plurality of rotor blades extending radially outward from the rotor disk. The assembly also includes a casing that at least partially circumscribes the plurality of rotor blades. The assembly also includes a dynamic sealing device coupled to the stator assembly. The at least one dynamic sealing device is configured to insert a seal between the casing and the plurality of rotor blades to facilitate reducing a clearance gap defined between the plurality of rotor blades and the casing while the rotor assembly is operating.Type: ApplicationFiled: October 9, 2013Publication date: April 9, 2015Applicant: General Electric CompanyInventor: Michael John Bowman

Patent number: 8973263Abstract: A method of manufacturing a carbon composite duct assembly includes providing a first carbon composite fabric layer having a first section. The first section is formed into a first portion and a second portion. The first portion is separately moveable relative to the second portion. The first portion overlaps the second portion to define a first corner of the first carbon composite fabric layer. The first carbon composite fabric layer is formed into at least a portion of a duct extending along an axis.Type: GrantFiled: April 26, 2011Date of Patent: March 10, 2015Assignee: United Technologies CorporationInventor: Anthony Rivera

Patent number: 8967078Abstract: A method of masking a component includes installing a flexible gasket over a portion of a component masking area leaving an unmasked area exposed. A backer is installed over the flexible gasket to compress the flexible gasket between the backer and the portion. The flexible gasket and the backer are secured to the component to provide an assembly. The assembly is deposited into a slurry with an abrasive media to polish the unmasked area, in one example. The flexible gasket and backer prevent abrasive media from reaching the masked area. The flexible gasket and backer can be removed from the component and reused on other similarly shaped components.Type: GrantFiled: August 27, 2009Date of Patent: March 3, 2015Assignee: United Technologies CorporationInventors: Ronald R. Soucy, Richard W. LaFranchise

Patent number: 8966753Abstract: A method for mounting a wind turbine blade to a wind turbine hub by use of a crane boom is provided. An orientation of the blade is kept substantially horizontal when the blade is lifted off the ground and mounted to the rotor hub. Control wires, which connect the blade via the crane boom to a winch arrangement, are used for keeping the blade orientation substantially horizontal in addition to at least one bearing wire for bearing the blade weight.Type: GrantFiled: April 6, 2012Date of Patent: March 3, 2015Assignee: Siemens AktiengesellschaftInventors: Henrik Lynderup Hansen, Jesper Moeller

Publication number: 20150040570Abstract: In one embodiment, a gas turbine engine component includes a foam based core and a composite skin member. Both the foam based core and the composite skin member can be used to structurally support the gas turbine engine component. The composite skin member can be a CMC material and is used to partially encapsulate the foam core. The gas turbine engine component can take the form of an airfoil member such as a blade or a vane, a combustor liner, etc. A first portion of the composite skin member includes a first surface extending past an edge of the component creating a step approximate an edge section. In another embodiment, composite skin members can be used to form a continuous shape for the edge section such that the foam core forms part of a gas path surface.Type: ApplicationFiled: December 23, 2013Publication date: February 12, 2015Inventors: Richard C. Uskert, Ted J. Freeman, David J. Thomas
