Sul perche' GE non si sia mossa per il 350 non so, ma di sicuro Airbus ora ne trarrebbe giovamento.

Nota di GE datata 2005:


Airbus and GE Integration on New A350 Aircraft Progressing Successfully
July 28, 2005

EVENDALE, Ohio - With more than 125 commitments announced for the new Airbus A350 aircraft, integration teams between Airbus and engine supplier General Electric Company have reached a key milestone in designing the overall propulsion system.

The GEnx engine, GE's newest commercial jet engine, is designated to power these A350 orders. The GEnx-powered A350 is scheduled to enter revenue service in 2010.

In establishing the propulsion system, integration teams representing Airbus, GE, and Goodrich Aero have defined the key interfaces between the GEnx engine and the aircraft inlet, nacelle, and thrust reverser. The team has also been engaged in defining the engine mounts, gearbox concepts, and the engine pneumatic bleed and electrical system.

Airbus has established an integrated certification schedule, which includes GEnx engine certification in 2007, flight tests in 2009, and aircraft/engine certification in 2010. GE has a full-time team of engineers at the Airbus headquarters in Toulouse, France, collaborating on the A350 program.

"In freezing the initial product definition and launching the GEnx engine, we have essentially established the performance parameters for the GEnx engine on the A350," said Tom Brisken, general manager of the GEnx program. "We are thrilled to be in a position to use our engine to help optimize the performance of the aircraft system."

The GEnx engine has received more than $2 billion in orders and commitments on the strength of new technologies that make it the most fuel efficient, quiet, and low-emissions jet engine that GE has ever introduced for large jet aircraft.

The GEnx is part of GE's "ecomagination" products portfolio - GE's commitment to develop new, cost-effective technologies that will enhance customers' environmental and operating performance. Based on the architecture of the renowned GE90, the GEnx is the next-generation of engine technology to succeed GE's CF6, the best-selling engine for wide-body aircraft. Compared to the CF6 family, the GEnx will improve specific fuel consumption by 15 percent.

The GEnx is the world's only jet engine with a front fan case and fan blades made of composites for greater durability and weight reduction. It will operate with 18 fan blades (50 percent fewer than the CF6), which helps provide noise levels lower than any large commercial engine developed by GE.

Mi ricordavo di aver letto qui (@13900 ?) che il progetto UltraFan fosse stato messo in un cassetto in quanto nessun manufacturer se lo fila. Eppure:
Rolls-Royce announces successful run of UltraFan technology demonstrator to maximum power

SI, nel 2021 dicevano che non avrebbero continuato a meno che non ci fosse stato un nuovo aereo: Rolls-Royce to put engine development ‘on ice’ until new jet unveiled (ft.com)

Mr East has previously said the company would seek new forms of industrial collaboration to help bring UltraFan technology to the commercial market. Speculation has focused on reviving the partnership with Pratt & Whitney, or a new collaboration with France’s Safran, which makes single-aisle engines through a joint venture with General Electric of the US. However these players have little reason to help Rolls-Royce re-enter the highest-volume segment of the aero-engine market, several analysts suggest.
In soldoni, dicevano che gli servono (tanti) quattrini per industrializzare il prodotto, e che se non ci sono aerei nuovi in progetto allora non c'e' motivo di buttarsi.

A naso, direi che stanno spendendo quattrini Q.B. per arrivare al punto in cui il motore e' certificato, o comunque sufficientemente maturo, e basta giusto giusto che qualcuno je allunghi quella manata di miliardi per passare da prototipo a pre-serie a serie.

Il nuovo CEO ha detto quanto segue:

Tufan Erginbilgic, Rolls-Royce chief executive, says: “This fantastic milestone puts us in a strong position to support the plans of our customers as they develop the next generation of super-efficient aircraft.”

Non dico che stia sventolando le ciglia verso Airbus, ma quasi.

I test dovrebbero proseguire ancora per un po', anche se non è chiaro per quanto.
E dubito anche che in un clima di crescente sensibilità ambientale, le compagnie possano permettersi di schifare un motore che promette un risparmio di carburante del 10% rispetto ai già ottimi TrentXWB. Per non parlare dei vantaggi economici.
Serve un "ponte" finanziario che porti dagli attuali test, alla certificazione. Se RR faticasse a trovare la liquidità necessaria (o giudicasse eccessivo il rischio di procedere senza nessun programma di Airbus e Boeing formalmente abbinato ai nuovi motori), potrebbe essere uno dei due costruttori a dare una mano. Con Airbus in pole position.
