The GEnx is derived from the GE90 with a fan diameter of During the spring and summer ofGE learned of four F freighters that suffered icing in their engines at altitudes of 40, feet and above.

General Electric GEnx – Wikipedia

One failure was caused by an assembly problem, which led to inspections of all other engines then in service. Unlike the initial version, for thethis version has a traditional bleed air system to power internal pneumatic and ventilation systems. This page was last edited on 27 December gejx, at The GEnx uses some technology from the GE90 turbofan [4]including composite fan blades, and the smaller core featured in earlier variants of the engine.

Introduced in late on a freighter, Cargolux surpassed one million flight hours in early State-of-the-art industrial resources With this new-generation engine, disassembly and assembly operations require much stringency. To reduce fuel burn, the As mentioned above, the company aims to ramp up repair processes for combustir chamber components, in addition to assembly and disassembly operations.

General Electric aircraft engines. Worldwide the Dreamliner fleet is growing and therefore the GEnx engine share is increasing as well. Both engines enable the move towards the More Electric Aircraftthat is, the concept of replacing previously hydraulic and pneumatic systems genc electrical ones to reduce weight, increase efficiency, and reduce maintenance requirements.

Retrieved 6 October The most serious incident involved an AirBridgeCargo freighter; on July 31, while at an altitude combustoor 41, feet over Chinathe flight crew noted two engines surging while a third lost substantial power.

Retrieved from ” https: Consequently, CRMA has developed an innovative industrial resource, which is unique in the world, tailored to draconian inspection requirements.

The GEnx and the Rolls-Royce Trent were selected by Boeing following a run-off between the three big engine manufacturers.

Air France Industries KLM Engineering & Maintenance – Engine Parts Repair

General Electric began initial test runs of the bleedless GEnx variant on 19 March In fact, triggered by offering its customers a wide repair capability, CRMA decided to dedicate a development engineer for this project and started working on developing GEnx repairs early Among the possible factors cited was “‘unique convective weather systems’ such as unusually large thunderstorms reaching high altitudes.

The pilots were combustorr to land the plane safely but the engines were found to have sustained damage. combustro

In the near future CRMA will extend repairs capability to combustion chamber dome’s deflectors and replacement of genc thermal barrier coating. The engine carries composite technology [5] into the fan case. Retrieved 18 October Once again, the Group is putting its full weight and the complementary benefits of its global MRO network at the disposal of its clients.

Boeing Boeing Dreamliner. It will also have a smaller overall diameter than the initial model to accommodate installation on the To reduce maintenance cost and increase engine life, spools with lower parts count are achieved by using blisks in some stages, low blade counts in other stages and by using fewer stages; internal engine temperatures are reduced due to more efficient cooling techniques and debris extraction within the low-pressure compressor protects the high-pressure compressor.

Retrieved June 10, To reduce weight, it features 18 composite fan blades, a composite fan case and titanium aluminide stage 6 and 7 low-pressure turbine blades. In Marcha GEnx-powered Boeing had its first in-flight shut down in operation when a JAL flight had to divert to Honolulu after an oil pressure alert, bringing its in-flight shut down geenx to 1 perhours.

GEnx Development Emphasizes Composites, Combustor Technology

Boeing wanted to allow changing between alternative engines within 24 hours, but had not worked it out by Fan blades have steel alloy leading edges and the composite fan case reduces thermal expansion.

It has a 10 stage high-pressure compressor and is quieter, helped by larger, more efficient fan blades. High-bypass turbofan engines General Electric aircraft engines Turbofan engines — The laser inspection carried out using the Faro 3D arm software that gwnx have developed, which scans the targeted areas before modelling them in real time in 3D, is the perfect response geenx this requirement.
