What technology is used in the engine of Boeing 787?

General Electric Company and Rolls-Royce provided the 787 with a new generation of engine technology. The engine of 787 is based on the successful GE GE90 and Rolls-Royce Trent engine products. When these two engines are put into use "out of the box", they will be certified for extended range flight (ETOPS). In addition, Boeing's proprietary technology and computer fluid dynamics (CFD) optimize the integration of the engine and the 787 fuselage, minimize interference resistance, and optimize the benefits of these technological advances. The serrated edge on the engine room greatly reduces the noise of the shock absorber in the rear cabin.

The engines on the wings of 787 aircraft can be interchanged, which can reduce the variability of configuration and system as much as possible, and realize the easier and more economical reconfiguration, upgrade and modification when the aircraft transitions between different fleets. This standardized and simplified way increases income potential, reduces operating costs, and endows 787 with discount ability and higher residual value.

The bypass ratio of Boeing 787 engine is about 10, while the bypass ratio of previous engine is about 5. The multiplied bypass ratio makes the community noise of the 787 engine lower and the fuel consumption greatly reduced. Lower emissions and fuel consumption can reduce the cost of 787 operators and reduce the environmental impact of aircraft.
