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...
The article reports on plans of aircraft maker Boeing to upgrade the 777-300ER aircraft. It mentions the details of plan revealed at the International Society of Transport Air Trading meeting in Arizona on March 9, 2015. It adds that the upgrade is aimed at improving fuel-burn savings in ...
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 ov...
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 ...
"Delta will continue flying its fleet of long-haul next generation Airbus A350-900s, which burn 21% less fuel per seat than the 777s they will replace," the airline said in a statement. So, the A350s will be deployed on some of the airline's transpacific routes it was not already...
A step climb or multiple step climbs of 2,000 feet altitude may be used when beneficial to minimize fuel burn. Fixed Allowances: For the purpose of this guarantee and for the purpose of establishing compliance with this guarantee, the following shall be used as fixed quantities and allowance...
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 775,000 pound plane is fitted with General Electric GE9X engines, the most powerful engines ever mounted on a commercial airliner. These burn 10% less fuel than those used on current 777s. Inside the cockpit, the flight deck incorporates touchscreen displays that can support multiple touch...
“Now we see the advent of even more efficient engines and wing design that take this to the next level in terms of lower fuel burn, lower noise and longer range.” Today, Boeing has delivered more than 1,400 747s to airlines around the world – not bad for a plane now into its fi...
