ANNUAL DISPATCH #4 • TURBOFAN PROPULSION

The Boeing 777's GE90 Engine Is Wider Than a Boeing 737 Fuselage

Aircraft: Boeing 777-300ER / GE90-115B Category: Turbofan Propulsion Benchmark: 3.43 m (135 in) Diameter

Engineering & Operational Context

The General Electric GE90-115B turbofan that powers the Boeing 777-300ER has a fan diameter of 11.25 feet (3.43 meters). The engine cowl measures 12.5 feet (3.8 meters) across, which is wider than the entire 12.3-foot (3.76 meter) exterior fuselage cross-section of a Boeing 737 passenger cabin.

Fact #3

The Boeing 747 Fuselage Was Longer Than the Wright Brothers' Entire First Flight

KEY STAT 195 ft vs 120 ft

When the original Boeing 747 took to the skies in 1969, its 195-foot (59.6 meter) fuselage was substantially longer than the entire distance traveled by Orville Wright on his historic maiden flight at Kitty Hawk in 1903, which covered only 120 feet (36.5 meters).

Fact #7

The Boeing 787 Wings Can Flex Upward by Over 26 Feet Without Breaking

KEY STAT 26.2 ft (8.0 m) Flex

Built predominantly from carbon-fiber reinforced polymer (CFRP), the wings of the Boeing 787 Dreamliner are engineered to flex gracefully under turbulent loads. During extreme ultimate static load testing, Boeing bent the 787 wings upward by more than 26.2 feet (8 meters), reaching 150% of the maximum aerodynamic load the jet will ever encounter in commercial service.
