After waiting three decades for enabling technology to catch up with its design ideas, GE-Aviation is deeply embedding itself in composite. The GEnx-1B has won about a 65 percent share of the Boeing as well as its combustor lining and fuel nozzles— will offer operators of. TAPS II Combustor. Final Report.

General Electric GEnx – Wikipedia

This page was last edited on 27 Decemberat In earlyof orders for the Bselected the GEnx In other projects Wikimedia Commons. To reduce fuel burn, the To reduce maintenance cost and increase engine cimbustor, 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.

Once again, the Group is putting its full weight and the complementary benefits of its global MRO network at the disposal of its clients. The GEnx is derived from the GE90 with a fan diameter of Worldwide the Dreamliner fleet is growing and therefore the GEnx engine share is increasing as well.


Boeing Boeing Dreamliner. General Electric began initial test runs of the bleedless GEnx variant on 19 March During the spring and summer ofGE learned of four F freighters that suffered icing in their engines at altitudes of 40, feet and above. The laser inspection carried out using the Faro 3D arm software that we have developed, which scans the targeted areas before modelling them in real time in 3D, is the perfect response to this requirement.

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.

High-bypass turbofan engines General Electric aircraft engines Turbofan engines — It will also have a smaller overall diameter than the initial model to accommodate installation on the 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.

Fan blades have steel alloy leading edges and the composite fan case reduces thermal expansion. Consequently, CRMA has developed an innovative industrial resource, which is unique in the world, tailored to draconian inspection requirements. 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 while a third lost substantial power.


Developing innovative repairs for engine parts is key when it comes to control engine maintenance costs.

GEnx Development Emphasizes Composites, Combustor Technology

Retrieved 18 October The engine carries composite technology [5] into the fan case. Commons category link from Wikidata.

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, comustor its in-flight shut down rate to 1 perhours. State-of-the-art industrial resources With this new-generation engine, disassembly and assembly operations require much stringency.

Air France Industries KLM Engineering & Maintenance – Engine Parts Repair

As mentioned above, the company aims to ramp up repair processes for combustion chamber components, in addition to assembly and disassembly operations. Views Read Edit View history.

General Electric aircraft engines. 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 Retrieved from ” https: Unlike the initial version, for thethis version has a traditional bleed air system to power internal pneumatic and ventilation systems.
