GE Aviation proposed the GE9X with a 128 in (325 cm) diameter fan, a 10:1 bypass ratio, a 60:1 overall pressure ratio, and 27:1 HP compressor ratio for a 10% fuel burn reduction.[5] 参考译文:早期的777-200LR和-300ER型号采用了通用电气GE90-115B发动机,具有42:1的总压比和23:1的高压...
Morris also thinks that there could be issues around residual values: “777-300ERs will typically be on 12-year finance terms or operating leases, so how will Boeing incentivise operators to keep those last-off-the-line -300ERs for 12 years in the face of their fuel-burn penalty o...
Comparing the performance of the two aircraft, we can see that their sizes are essentially identical. However, that's where the similarities end. The A350-900ULR outperforms the 777-200LR where it matters most: Range and fuel burn, with the Airbus flying much further while burning less fuel...

Destined to carry on the great success of the Boeing 777-300ER, the 777X offers airlines with a fuel burn reduction of around 20 percent. Additionally, passengers can enjoy a roomier cabin with larger windows. Boeing 777X economy cabin ...
The article reports on the launch of the 777 aircraft upgrade plan series of aircraft manufacturer Boeing on March 9, 2015. It states that the upgrade effort will include a series of product improvements to increase its airplane capacity by up to 14 seats and reduce fuel-burn consumption by ...
[47] Eastern Air Lines, the first 727 operator to take delivery of 757s, confirmed that the aircraft had greater payload capability than its predecessor, along with lower operating costs through improved fuel burn and the use of a two-crew member flight deck.[47] Compared with the 707 and...
The 777-8X will trim the seat count to 350 passengers but with a maximum range over 17,220km (9,300 nautical miles). In both cases, improved design and new-generation engines will see the planes burn less fuel than today's 777s. ...
The 767-400ERX would offer the capacity of the Airbus A330-200 with 3% lower fuel burn and costs.[158] Boeing cancelled the variant development in 2001.[64] Kenya Airways then switched its order to the 777-200ER.[181] 参考译文:7月推出的远程-400ERX将拥有更强的机翼、机身和起落架,最大...
The “Big Twin” will have25% more cargo capacitythan the standard B777 freighter, which is based on the -200LR series. Furthermore, the aircraft will burn21% less fuel per tonnethan a B747-400 freighter. Despite having a larger airframe and larger capacity, the “Big Twin” is expected...
