Boeing 777 is a twin-engine wide-body airliner developed by Boeing Company of the United States. One of its most obvious identification marks is its three-axis six-wheel main landing gear system and two front wheels. This structure not only effectively disperses the road load, but also makes the landing gear strut of the aircraft not more than three.
Extended data:
Main models of B777
I. B777-200 type, basic type.
2.B777- 200ER(IGW) and 200 extended range models, by changing the internal structure, increase the total takeoff weight and fuel load, so that the maximum fuel range can reach 14000 km.
3.B777-300 is an extended version of Model 200, the longest twin-engine jetliner in the world, which is10m longer than Model 200 and 3.2m longer than Boeing 747-400. It has the same fuel load as the 200IGW model, and the range can reach 1 1000 km.
The passenger capacity of Boeing 777-300 is the same as that of Boeing 747- 100/-200. Fuel consumption is reduced by one third, and maintenance costs are reduced by 40%. This can meet the needs of customers who want to replace early Boeing 747 models.
