GENX™ high bypass turbofan engines

The GEnx is the workhorse engine of the 21st century for medium and large-capacity, long-range aircraft, thanks to its tremendous improvements in efficiency and low cost of ownership. The GEnx is delivering up to 15 percent better specific fuel consumption than the engine it replaces, helping operators save whenever they fly. It’s designed to stay on wing 20 percent longer, while using 30 percent fewer parts, helping to keep maintenance costs in check. The GEnx’s emissions are up to 95 percent below current regulatory limits, ensuring clean compliance for years to come. It is the quietest, most passenger-friendly commercial engine GE has ever produced. All of these improvements are thanks to the incorporation of advanced and proven technologies from other engine families and on-going R&D programs. Like lightweight, durable composite materials and specialized coatings. An innovative, clean-burning combustor, a counterrotating architecture. And a fan module that’s virtually maintenance-free.

Designed around our customers’ needs, the GEnx represents a giant leap forward in propulsion technology. The GE GEnx™ is a high-bypass turbofan engine developed by GE Aerospace, primarily for the Boeing 787 and 747-8 aircraft. It's a dual-rotor, axial-flow engine with a high bypass ratio designed to improve fuel efficiency, reduce noise, and lower maintenance costs compared to its predecessor, the CF6.

High Bypass Ratio: The GEnx features a high bypass ratio, meaning a large portion of the air is drawn in by the fan and bypasses the core engine, generating a significant amount of thrust without requiring as much fuel.

Dual Rotor Design: The engine uses two separate rotors, one for the high-pressure compressor and turbine, and another for the low-pressure compressor and turbine, which contributes to efficiency.

Advanced Materials and Technologies: The GEnx incorporates advanced materials like carbon fiber composite fan blades and cases, which reduce weight and improve durability.

Lean-Burning Combustor: The engine uses an innovative lean-burning twin-annular pre-swirl (TAPS) combustor to reduce NOx emissions and improve durability. Maintenance-Friendly Design: The engine is designed for reduced maintenance needs, with features like a maintenance-free fan module.

Improved Fuel Efficiency: The GEnx offers significant improvements in fuel efficiency compared to its predecessors, leading to lower operating costs. Versions and Applications:GEnx-1B: Designed for the Boeing 787 Dreamliner.GEnx-2B: Designed for the Boeing 747-8.

Benefits:

Reduced Fuel Consumption: The high bypass ratio and advanced design contribute to lower fuel

consumption and reduced operating costs. Lower Noise Levels: The GEnx is designed to be quieter than previous GE engines, making it more passenger-friendly. Reduced Emissions: The lean-burning combustor and other design features help reduce emissions, including NOx.

Increased Reliability: The GEnx is designed for high reliability and reduced maintenance needs.
