What will happen if Boeing introduces a dual-engine version of the 747-8i based on the current 747-8i in the future?
The first is the engine. GE9X originated from the 777-9X has strong thrust and better economy, which is better than the original four GEnx-2b in thrust and maintenance economy,Fuel consumption is reduced by about 15% and noise is reduced by 20%.
Secondly, the fuselage material, because of the excellent performance of carbon fiber composite materials on the 787 and A350, Boeing decided to increase the proportion of composite materials of this aircraft to 48%, which was about 25% lower than the previous empty weight, so that the fuel load and the maximum takeoff weight were obviously improved compared with the previous ones. At the same time, Boeing also abandoned the cable drive system and adopted the fly-by-wire flight control with lower weight and higher electrification, and the cockpit continued for 777-9X.
