GE90 Engine

GE Aerospace

A giant inthe industry

Launched in 1990, the GE90 engine is GE Aerospace’s first engine in the 100,000-pound thrust class and became the most technologically advanced commercial turbofan engine in 25 years.

    Maturation at its finest
    GE Aerospace has continued to invest and improve the engine. GE Aerospace engineers have enhanced the GE90-115B engine’s compressor, combustor, and high- and low-pressure turbine components to reduce weight, improve fuel efficiency, and enhance durability.
    • 3.6% reduction in fuel burn from initial launch specification
    • 60% improvement in time on wing
    • World-class 99.98% reliability rate
