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. 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 rate to 1 perhours.

General Electric began initial test runs of the bleedless GEnx variant on 19 March Views Read Edit View history. Retrieved June 10, During the spring and summer ofGE learned of four F freighters that suffered icing in their engines at altitudes of 40, feet and above.

Retrieved 6 October The GEnx and the Rolls-Royce Trent were selected by Boeing following a run-off between the three big engine manufacturers.

Among the possible factors cited was “‘unique convective weather systems’ such as unusually large thunderstorms reaching high altitudes. Both engines enable the move towards the More Electric Aircraftthat is, the concept of replacing previously hydraulic and pneumatic systems with electrical ones to reduce weight, increase ggenx, and reduce maintenance requirements.

It has a 10 stage high-pressure compressor and is quieter, helped by larger, more efficient fan blades. Ccombustor the initial version, for thethis version has a traditional bleed air system to power internal pneumatic and ventilation systems. The most serious incident involved an AirBridgeCargo freighter; on July 31, while at an altitude of 41, feet over Chinathe flight crew noted two engines surging fenx a third lost substantial power.

Located in northern France, the future site will implement high-tech metallurgical processes and innovative management principles that leave plenty of scope for staff empowerment and creativity. To reduce weight, it features combutsor composite fan blades, a composite fan case and titanium aluminide stage 6 and 7 low-pressure turbine blades.

Worldwide the Dreamliner fleet is growing gehx therefore the GEnx engine share is increasing as well. Commons category link from Wikidata. Introduced in late on a freighter, Cargolux surpassed one million flight hours in early Fan blades have steel alloy leading edges and the composite fan case reduces thermal expansion.

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 In the near future CRMA will extend repairs capability to combustion chamber dome’s deflectors and replacement of the thermal barrier coating. Developing innovative repairs for engine parts is key when it comes to control engine maintenance costs.

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.

The GEnx is derived from the GE90 with a fan diameter of Boeing wanted to allow changing between alternative engines within 24 hours, but had not worked it out by One failure was caused by an assembly problem, which led to inspections of all other engines then in service.


The engine carries composite technology [5] into the fan case. Retrieved from ” https: The pilots were able to land the plane safely but the engines were found to have sustained damage. To reduce fuel burn, the Boeing Boeing Dreamliner.

Consequently, CRMA has developed an innovative industrial resource, which is unique in the world, tailored to draconian inspection requirements. State-of-the-art industrial resources With this new-generation engine, disassembly and assembly operations require much stringency.

Once again, the Group is putting its full weight and the complementary benefits of its global MRO network at the disposal of its clients. It will also have a smaller overall diameter than the initial model to accommodate installation on the As mentioned above, the company aims to ramp up repair processes for combustion ccombustor components, in addition to assembly and disassembly genc.
