PARIS AIR SHOW: Turkish Airlines signs for seven more A330s
By David Kaminski-Morrow
Turkish Airlines has tentatively agreed to acquire another seven Airbus A330 aircraft.
It has signed a memorandum of understanding for the twin-jets, five of which will be A330-300s.
The remaining two will be the higher-weight version of the A330-200.
Turkish Airlines has not given an engine selection for the aircraft - although its seven current A330s are General Electric CF6-powered.

Airbus, which disclosed the agreement during the Paris Air Show, says the aircraft are scheduled for delivery from August next year.
Turkish Airlines chairman Candan Karlitekin says the higher-weight A330-200s will allow the carrier to expand its network on routes such as Istanbul-New York.

The A330-300s, he adds, will be deployed on high-capacity medium-haul sectors.
Turkish Airlines is preparing to confirm details of a large order expected to comprise more than 100 aircraft.

Le point significatif ici ? RR, avec son RR Trent 700EP, a "renversé" le choix antérieur des moteurs GE (CF-6) !

Fresco a écrit:Merci Pascal !

Je ne comprend toujours pas pourquoi GE n'est pas sous l'aile du 330F

sevrien a écrit:C'est son choix, Fresco !

C'est tout ! Puis, GE a des problèmes graves avec ses CF-6 !

GE drops A330-200F plan and opens door to P&W

Je pourrais vous indiquer pas mal de mes propres écrits à ce sujet, .....mais, cela ne vaudrait peut-être pas la peine.

Rolls-Royce, the global power systems company, plans to make further performance improvements to its market-leading Trent 700 engine that powers the Airbus A330.

Technologies already proven on Rolls-Royce Trent 1000, Trent XWB and BR725 engines are available to be incorporated into the Trent 700 to deliver increased efficiency of at least one per cent. The improvement programme will also focus on engine service support.

The Trent 700 is the best-selling member of the Trent engine family, with more than 1,400 either sold or on order. It is the market leader on the Airbus A330, accounting for around three quarters of future engine orders on the aircraft.

The improvement programme will be finalised this year, with enhanced engines expected to enter service in 2015. Improvements will also be available for retrofit to the current engine fleet. The enhanced Trent 700 will complement the improvements to the A330 aircraft that Airbus has announced.

Tom Palmer, Rolls-Royce, Project Director - Trent 700, said: “The market’s favourite engine for the Airbus A330 is about to get even better. We are committed to continually improving every member of the Trent family as we develop new technology that improves efficiency. We now look forward to working with our customers and Airbus to bring this new standard of Trent 700 to the market, where I am sure it will prove popular for decades to come.”

The Trent 700 is the only engine specifically designed for the Airbus A330 and entered service in 1995. The improvement programme announced today is in addition to enhancements introduced in 2009, incorporating Trent 900 and Trent 1000 technology, that delivered a one per cent reduction in fuel consumption.

Trent 700 fuel burn is said to have benefitted by 1.1 percent from an EP retrofit package introduced in 2009, with an “EP2” expected to follow in two years’ time, although RR does not yet know if this will be available for retrofit. The initial Trent 700 EP retrofit kit includes ELE IPC/HPC blades and optimized turbine-case cooling. These changes are available on new-build engines, along with other developments such as optimized blade-tip clearance, “pocket-less” fan-spinner fairing, “super-polished” turbine hardware, and HPC improvements that together give new engines a 1.3 percent fuel-efficiency gain.
Planned Trent 700 EP2 characteristics that will lead to a new 2015 build standard and which could yield one-percent fuel-burn improvements (worth $200,000 per aircraft per year) include HPC and IPC stator-blade changes, better nozzle guide-vane (NGV) sealing and an improved “aero-standard flutter bridge” in the low-pressure turbine (LPT). As Airbus A330 popularity continues, the engine manufacturer is producing “more [Trent 700s] than ever before.”
R-R (Chalet B89) said last month that an EP2 package would run this year, following an initial EP upgrade that improved fuel burn and enhanced engine reliability. “Delays and cancellations and unscheduled engine-removal rates have improved by 50 percent in the past two years,” according to Hogarth
