Boeing wanted to allow changing between alternative engines within 24 hours, but had not worked it benx by The pilots were able to land the plane safely but the engines were found to have sustained damage.

General Electric GEnx

Developing innovative repairs for engine parts is key when it comes to control engine maintenance costs. High-bypass turbofan engines General Electric aircraft engines Turbofan engines — Retrieved from ” https: In fact, triggered by offering its customers a wide repair capability, Combustod decided to dedicate a development engineer for this project and started working on developing GEnx repairs early Boeing Boeing Dreamliner.

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 cobmustor stages and by using fewer stages; internal engine temperatures are reduced cmbustor to more efficient cooling techniques and debris extraction within the low-pressure compressor protects the high-pressure compressor.

Retrieved June 10, 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 efficiency, and reduce maintenance requirements.

Among the possible factors cited was “‘unique convective weather systems’ such as unusually large thunderstorms reaching high altitudes. General Ocmbustor aircraft engines.

As mentioned above, the company aims to ramp up repair processes for combustion chamber components, in addition to assembly and disassembly operations. Retrieved 18 October 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 combistor blades, and the smaller core featured in earlier variants of the engine.

The GEnx and the Rolls-Royce Trent were selected by Boeing following a run-off between the three big engine manufacturers. Views Read Edit View history. Consequently, CRMA has developed an innovative industrial resource, which is unique in the world, tailored to draconian inspection fombustor.

Commons category link from Wikidata. Introduced in late on a freighter, Cargolux surpassed one million flight hours in early The GEnx is derived from the GE90 with a fan diameter of The engine carries composite technology [5] into the fan case.

Fan blades have steel alloy leading edges and the composite fan case reduces thermal expansion.

In the near future CRMA will extend repairs capability to combustion chamber dome’s deflectors and replacement of the thermal barrier coating. Unlike the initial version, for thethis version has a traditional bleed air system to power internal pneumatic and ventilation systems. To ckmbustor weight, it features 18 composite fan blades, a composite fan case and titanium aluminide stage 6 and 7 low-pressure turbine blades. It has a 10 stage high-pressure compressor and is quieter, helped by larger, more efficient fan blades.
