2019年9月27日 · The GE90's aren't like a miracolous cure for every plane. You know, you cannot simply attach two GE90s to a plane to make it very fuel efficient, profitable, affordable and dependable.

The 777 is powered by two General Electric (GE90) engines. They are the most powerful engines ever installed in the 777, each having a thrust rating of between 360 to 510 kN.

2018年11月19日 · I guess that with a robust weight saving programme and having two GE90's, this A340-600 configuration would have been a robust competitor to the Boeing 777-300.

The General Electric GE90 is a family of high-bypass turbofan aircraft engines built by GE Aerospace for the Boeing 777, with thrust ratings from 81,000 to 115,000 pounds-force (360 to 510 kilonewtons). It entered service with British Airways in November 1995.

A340-300别名为5APU，起因是因为它机翼下挂的CFM-56-5C [1] 发动机与波音777使用的GE-90系列，PW4000系列，Trent系列相比推力太小（139kn--151kn），推重比也小，这就像挂了4个APU（辅助动力单元，用于提供额外电力及空气），再加上其尾部真正的APU，因此得名

2025年2月24日 · The GE90, for instance, is the world’s most powerful jet engine, which allows the 777 to carry heavy loads over long distances. In contrast, the A340’s engines, while reliable, don’t quite match the thrust-to-weight ratio of the 777, impacting its fuel efficiency on long-haul routes.

The Airbus A340 is a long-range, wide-body passenger airliner that was developed and produced by Airbus. In the mid-1970s, Airbus conceived several derivatives of the A300, its first airliner, and developed the A340 quadjet in parallel with the A330 twinjet.

With the A340-600 and 777-300ER as main contenders to replace the 747-400, this analysis examines which of the two is the most efficient performer. Both the A340-600 and the 777-300ER can carry additional freight payload above a full passenger load, but …

2002年11月18日 · Looks like the GE90-110/115 could be the best selling engines ever for the 777 aircraft! The GE90/777LR has arguably influenced JAL's -200ER powerplant choice, as well as PIA's recent choice in favor of the GE90. Alitalia also selected the GE90-94B for its -200ERs after ordering -200ERs and taking options on -300ERs.

A340和A330共享飞控、机身、机翼，零件互换性达到85%。 一起研发的好处就是空客可以短时间内把这两款客机迅速投入市场，占得先机。
