Engine Alliance GP 7200

In an interesting briefing by EA’s President Mary Ellen Jones, we learned that the GP7200 is now 1.4% better in fuel burn and 200 pounds lighter. The engine is doing very well, and given A380s and engine news, this is a great story to be telling. Supporting EA’s upbeat presentation was A380 Product Marketing Director Richard Carcaillet. The EA team state theirs is now the better engine and offer supporting data.

ngine Alliance, in combination with Airbus, is adding a 72,000 lb. thrust rating to the GP7200 engine to the A380 catalogue to offer additional takeoff weight performance on short runways.

The software upgrade to the full authority digital engage control system is due to undergo flight testing in the coming months, with the goal to certify the thrust rating next year, says Mary-Ellen Jones, president of the General Electric, Pratt & Whitney joint venture. It either allows 7.5 metric tons more of payload on a 2,500 meter runway or 240 naut. mi. more range.

The option could aid long-range operations out of Los Angeles and also support Airbus’s move to offer a 575 metric ton high gross weight version of the A380 starting in 2013.

The GP7200 already has certified thrust ratings of 70,000 lb. and 76,500 lb. – the latter developed for the A380 freighter that has since been shelved.

Meanwhile, the Engine Alliance is working on additional weight savings to the engine, which now weighs about 200 lb. less than initial production turbofans. The latest change came with the introduction of a new turbine exhaust, developed by Volvo Aero, which cut weight by 54 lb. Other enhancements are in the works, but likely not with a single one offering quite such a large saving.

The company also is working on increasing its installed base. Currently, 27 A380s with GP7200s are in service – 17 with Emirates, six with Air France, and four with Korean Air; that should grow to 31 aircraft by year end, with Emirates taking three more aircraft and Korean Air getting a fifth.

Engine Alliance, along with rival Rolls-Royce, also are awaiting Qatar Airways’s A380 engine decision, which is due soon.

The Engine Alliance (EA) shipped the first GP7200 propulsor to Emirates on May 21.The delivery marks the first time the Engine Alliance and member company Pratt & Whitney have delivered a propulsor, rather than a full engine, to any airline.

“Shipping a propulsor is an innovative way to supply spare engines,” EA Chief Engineer Paul Smith explained. “The fan module has a very long life, so it can be reused with a new propulsor to provide a full spare engine. It's a huge cost savings for the customer.”

According to EA Industrial Director Marios Evripidou, delivering spare propulsors in lieu of spare engines also helps minimize an airline's inventory. “They don't have to keep as many unused fans in inventory because they can reuse the ones they already have,” he said. Shipping propulsors is easier than shipping a full engine, too, Evripidou said. Because they're smaller, they can be transported on most wide-body freighter aircraft. “It gives the customer great transportation flexibility,” he said.

Qatar Airways has selected Engine Alliance GP7200 turbofans to power its Airbus A380s.

The win for the General Electric/Pratt & Whitney joint venture continues its success in the Middle East, where Emirates and Etihad have also opted for the turbofan. It adds to the JVs lead in total number of A380s ordered over the rival Rolls-Royce Trent 900.

Qatar is due to receive its first A380 next year. It has ten A380s on order after doubling its commitment to the type in November during the Dubai air show.

The airline was late in making its engine decision, waiting to within two years of receipt of the first aircraft despite urging by Airbus to airlines make a selection at least 24 months out.

L’A380 de Qatar Airways motorisé par Engine Alliance


Publié le 6 février 2012 à 10h30 par François Duclos dans Actualité, Technologie - 0 commentaire



Engine Alliance, qui regroupe General Electric et Pratt&Whitney, a remporté un contrat préliminaire pour motoriser les Airbus A380 de la compagnie aérienne Qatar Airways.

D’une valeur estimée à 1,4 milliards de dollars, le contrat annoncé début février 2012 verra les réacteurs GP7200 équiper
les dix superjumbos commandés par la compagnie qatarie, dont cinq
ajoutés à sa commande initiale lors du salon de Dubaï en novembre 2011.
Le premier A380-800 doit être livré au premier semestre 2013, et
accueillera 517 passagers dont 42 en classe Affaires; la configuration
n’a pas encore été finalisée mais comprendra une Première, nouveauté dans la flotte de Qatar Airways. Le choix des routes sur lesquelles il sera déployé est toujours à l’étude.

Si l’accord est finalisé comme prévu dans les semaines qui viennent,
Engine Alliance aura donc été choisi pour équiper les A380 d’Air France, Emirates Airlines, Air Austral, Korean Air, Etihad Airways et donc Qatar Airways.

Son concurrent battu du jour, Rolls Royce et son Trent 900, a séduit la compagnie de lancement Singapore Airlines, Qantas Airways, China Southern Airlines, Lufthansa, et les futurs opérateurs British Airways, Virgin Atlantic, Thai Airways et Malaysia Airlines.

Qatar Airways a d’autre part annoncé espérer recevoir son premier Boeing 787 Dreamliner
en juin 2012, et quatre autres d’ici la fin de l’année. Configuré pour
environ 240 sièges dont 22 en Affaires, il sera d’abord déployé sur des
routes dans le Golfe Persique afin de parfaire l’expérience des
équipages, avant d’être envoyé vers l’Europe, Londres – Heathrow en
tête. La compagnie verra sa flotte de 104 avions augmenter de deux
appareils tous les quinze jours jusqu’à la fin de l’année, avant de
passer à deux appareils tous les 12 jours en 2013.
