International Classification:

B23P 1500

US Classification:

298891, 298892, 2940213

Abstract:

A method of repairing an annular transpiration cooled liner for a combustion chamber of a gas turbine engine. An annular portion of the liner including a damaged region is removed from between an upstream section and a downstream section of the liner. Sheet metal is formed into an annular replacement section having at least one axial seam extending between an upstream end and a downstream end of the replacement section. The replacement section is sized and shaped similarly to the removed annular portion of the liner. The upstream end of the formed annular section is joined to the upstream section of the liner and the downstream end of the formed annular section is joined to the downstream section of the liner.

International Classification:

US Classification:

370259

Abstract:

Provisioning of dedicated service in a communications network is made more efficient by creating a service path, ( ) that includes a permanent service communications link ( ) between an automatically remotely provisionable cross-connect system ( ) and a network gateway element ( ), such as a cross-connect device or a telecommunications switch. The service communications link remains active to carry traffic notwithstanding whether the automatically remotely provisionable cross-connection system is provisioned to provide dedicated subscriber service, or to terminate such service. In this way, service may be re-provisioned by appropriately provisioning the cross-connect device without the need to dispatch a technician to re-establish a link between the cross-connect system and the network gateway device.

International Classification:

F02C 712

US Classification:

60 3902, 60754, 298892

Abstract:

A method of adjusting airflow through a plurality of cooling holes by depositing a thermal barrier coating on an exterior surface and/or an interior surface of the component by a physical vapor deposition process. The cooling holes are not masked. Thus, a portion of the thermal barrier coating partially obstructs airflow through the cooling holes and reduces airflow through the cooling holes. A predetermined pressure drop is developed across the cooling holes and airflow through the cooling holes is measured. The measured airflow is compared to a preselected range of desired cooling hole airflows and the steps of depositing the thermal barrier coating, developing the predetermined pressure drop, calculating airflow and comparing the measured airflow to the preselected range are repeated until the measured airflow is within the preselected range of desired cooling hole airflows.

US Classification:

415191, 4152094, 4152101, 298891, 294023, 294029

Abstract:

A method for repairing a turbine nozzle segment having at least one vane disposed between outer and inner bands includes separating the inner band from the nozzle segment, and joining the inner band to a newly manufactured replacement casting having an outer band and at least one vane. The replacement casting includes a mounting platform formed on one end of the vane and a boss formed on the mounting platform. A collar is joined to the inner band and has a slot formed therein. The boss is then inserted into the slot, and the mounting platform is received in a recess formed in the inner band. Joining is completed by joining the boss to the collar and the mounting platform to the inner band.

US Classification:

60772, 60798, 60796, 60752

Abstract:

A cowl for directing flow of air entering an annular combustor assembly of a gas turbine engine and which is removable from the combustor without disassembling the combustor. The cowl is annular in shape and has a plurality of circumferentially spaced fastener holes for receiving fasteners which commonly connect and align the cowl, an annular dome, and a liner. At least one notch is in the cowl, each notch being sized sufficiently larger than a corresponding fastener to permit the cowl to be moved to or removed from an operative position while the corresponding fastener remains in position for connecting the dome and liner to one another.

International Classification:

B22F 100

US Classification:

75254, 148 24

Abstract:

A braze material and method for repairing an article, such as a gas turbine engine combustor liner formed from a nickel-base or cobalt-base superalloy. The braze material is composed of a nickel-base braze alloy that is preferably in powder form and may be dispersed in a suitable vehicle to yield a slurry, putty or solid tape. The braze alloy is formulated to be capable of withstanding the high temperature operating environment of a combustor liner, and to have a melting temperature below the grain growth or incipient melting temperature of the superalloy to be repaired. A preferred braze alloy is formed by combining at least two nickel-base powders. A suitable composition for the braze alloy is, in weight percent, about 10 to about 19 chromium, about 3 to about 10. 5 cobalt, about 1. 75 to about 4.

US Classification:

2989001, 2940203, 2940208, 298891

Abstract:

A replacement method facilitates replacing of a portion of a combustor liner within a gas turbine engine combustor in a cost-effective and reliable manner. The combustor includes a combustion zone that is defined by an inner and an outer liner. The inner and outer liners each include a series of panels and a plurality of nuggets formed by adjacent panels. The method includes the steps of cutting between an outer surface and an inner surface of at least one liner panel, removing at least one panel that is adjacent the area of the liner that was cut, and installing a replacement panel into the combustor for each panel that was removed from the combustor.

Abstract:

A method enables a portion of combustor dome assembly to be replaced. The dome assembly includes at least one dome cup including at least one swirl cup including a joint that defines a slot therein, and a deflector plate assembly that is coupled to, and extends downstream from, the swirl cup, such that a portion of the deflector plate assembly is securely fixed within the joint slot. The method comprises cutting through an interface formed between the deflector plate assembly and the joint slot, extending the cut substantially between the deflector assembly and the joint slot through the at least one dome cup, removing the deflector plate assembly from the combustor dome assembly, and coupling a replacement deflector plate assembly within the combustor dome assembly that extends aft from the portion of the combustor dome assembly that is upstream from the cut.
