Pour en remettre une couche
PW intéressé par la motorisation des A350-800 / -900
Pratt & Whitney is considering building an engine for the Airbus SAS A350 long-haul plane to challenge Rolls-Royce Holdings Plc (RR/)’s monopoly on the new aircraft, people familiar with the plan said.
Pratt & Whitney would offer an engine based on its PW1000G geared turbofan technology, said the people, who asked not to be named because the plan isn’t public. A decision to formally pursue the program may come as soon as this year, one of the people said.
Airbus had originally sought a second engine offering to Rolls-Royce’s TrentXWB on its A350. It had failed to persuade either General Electric Co. (GE), which powers the competing Boeing Co. (BA) 777, or Pratt & Whitney, which was tied up developing the geared turbofan. Airlines including Air France-KLM (AF) have said they’d welcome a choice because it would give them leverage on maintenance, a major source of revenue for Rolls-Royce.
Airbus, based in Toulouse in France, would have to sign off on the Pratt plan before airlines could opt for the engine. The company is “happy that the one engine we have on offer has already achieved 617 sales,” spokeswoman Marcella Muratore said. “However we have always said that we would consider other offers if they are competitive in terms of performance.”
“As Pratt & Whitney looks ahead to powering future wide- body applications, we will scale the geared turbofan architecture to the required thrust levels,” the company said in an e-mailed request for comment. “We continue to keep all airframers informed of our progress on the PW1000G family, including studies with Airbus for potential wide-body applications.”
Pratt & Whitney’s A350 engine would have to be more than twice as powerful as its existing versions. The company, a subsidiary of Hartford, Connecticut-based United Technologies Corp. (UTX), has undertaken studies that show the leap can be made even if technical hurdles must be overcome, one person said.
The engine maker remains interested in using its technology to power big jets, Bob Saia, who oversees Pratt’s next- generation products, said in an interview this month. Pratt decided not to compete for a spot on the upgraded version of Boeing’s 777 due around the end of the decade, a program drawing interest from GE and Rolls-Royce, the industry leaders.
Ma conviction à ce stade : le TXWB-84 est un peu surdimensionné pour les -800 / -900 vu qu'il était prévu à l'origine pour les -800 / -900 / -1000
Le -800 n'est pas optimisé mais pourrait l'être un jour
De la place donc pour un vrai 70-85 klbs et non un 80-95 klbs qu'est plutôt je pense le XWB tout court
