Bonjour !

P&W s'apprête à fêter sa "Victoire" sur le GE/RR pour la motorisation du F35 !
Gagné, quoi ?? en supprimant la concurrence sur une alternative de motorisation, en obtenant que les fonds soient coupés par le congrès ??
Pour un moteur presque fini et qui paraissait prometteur ! Du gâchis à ce niveau de complétion !
Pas de quoi danser sur la table!

La diversité ... c'est intéressant pour P&W sur le A320 !! Bien sûr, et tant mieux pour l'avion et les clients Airbus!
Et ennuyeux quand un monopole pour le F35 (Bien cher) est à risque, selon P&W ??
Les clients export apprécieront les premiers !
En plus le Moteur GE/RR, risquait d'être meilleur et moins cher (Ce sont eux qui le disaient, menfin !)

1000 et plus Avions, quels qu'ils soient, reposant sur un seul moteur, c'est anormal et risqué, sous tous les cieux !

Un peu de modestie ne ferait pas de mal à P&W ... le chemin du F35 est semé d'embuches, et les crédits militaires, ça va ça vient !

P&W pushes PW1000G as C919 second engine
By Jon Ostrower

Pratt & Whitney CEO David Hess says his company is in "on-going discussions" with Chinese airframer Comac to offer the PW1000G as a second western engine option on the 156-seat C919, as well as other powerplants for the 70-seat ARJ21 and new clean-sheet designs.

"We've had discussions with them about all three," says Hess, whose comments came at the engine-maker's 30 March media day. Comac is "very excited about a geared turbofan, they know where we are in development, they've seen the engine. In fact, we've had Comac people down here at test stands".

Hess says the initial selection of the [CFM International] Leap-X1C engine for the C919 has not ruled out the PW1000G: "Certainly their initial selection was Leap-X, they'll start a flight test programme with Leap-X, but they seem to be very interested in flying the next generation product family. Either on derivatives of the C919, the ARJ21 - they are studying possible applications for ARJ21 - and for and certainly clean sheet paper airplanes. They're very excited about it, we've got a good relationship with the Chinese."

The opportunity to offer a second engine option on the C919, which competes directly with the A320 and 737-800, would allow the Chinese to match European offering of next generation engines on its A320neo, which are both due for entry into service in 2016.

Additionally, Hess is encouraged by the newly formed partnership between Bombardier and Comac, potentially opening the door to offering the PW1000G on the C919 as it seeks to develop further commonality with Bombardier's CSeries, also powered by a variant of the geared turbofan.

The PW1524G, set to fly on Bombardier's CS100 in 2012 is currently in ground testing at P&W's West Palm Beach, Florida and Manitoba, Canada test facilities.

"We're not privy to the conversations between Comac and Bombardier, but clearly there could be opportunity for collaboration on all the platforms," says Hess. "I think it's a great idea, I think it will certainly give Bombardier access to the Chinese marketplace, and maybe some Chinese capital, and vice versa it will give the Chinese access to Bombardier's great technical and development capabilities.

For smaller aircraft, P&W currently offers the PW1200G for the 70 to 90-seat Mitsubishi Regional Jet, but either that engine or the PW800, a non-geared architecture with the PW1000G's core, would likely be available for the ARJ21, which P&W says would offer a 10% specific fuel consumption improvement over the General Electric CF34-10A engines currently offered on the Chinese regional jet.

"We feel pretty good that we're going to have good opportunities for Pratt in China going forward," he adds.

J'imagine que P&W, demande légalement à RR, de vérifier si leur projet de Fan, pour le GTF, rentre ou pas dans leurs licences, je suppose que c'est à travers leurs agents de brevets et dans le cadre d'une démarche à travers des services juridiques spécialisés ! (Un pré-jugement, assez simplifié)
Ca ne doit pas vraiment se passer trop à l'amiable ...

Injunctive relief !

Ca explique bien que P&W, n'annonce rien, pour le Fan du GTF, ils ont plusieurs fers au feu je suppose !
Dont un fan à 4 Courbures, peut être ... Ouarf !

En attendant, P&W a toujour une action en cours, concernant les T1000, qui concerne la forme de aubes de turbines, laquelle va venir sur le tapis dans qq mois ...

Bonjour !

Ramené par le Cousin sur A.Web !
Un commentaire de AirInsight, de Ernest Arvaï !

C'est tout à fait dans la ligne de ce que l'on écrit !
Bon, settlement définitif où appel de RR ??

C'est à suivre quand même, attendre aussi le résultat de la "Voluntary injunction" qui devrait libérer totalement P&W ... pour les GTF, pas de doute que P&W présenteront une forme qui n'empiète pas sur le brevet, ils ne sont pas suicidaires, et, de plus ils doivent avoir le ou les plans B, juste in case !
Ils ne vont pas jouer des milliers de GTF à produire à la roulette, chez P&W !

Noter aussi, dans un improbable "Worst case" ..; que l'on parle de 0,5% d'améliorations, pour la part du "Fan" en S, sur des moteurs qui passent le "Benchmark" promis de 2% avant l'EIS ... donc, il n'y a même pas le feu au lac !

---------------- Airinsight , le lien et un extrait -----------------

http://airinsight.com/2011/05/23/rolls-loses-patent-infringement-case-against-pratt-whitney/

A patent infringement lawsuit by Rolls Royce against Pratt &
Whitney, a division of United Technologies regarding fan blade design
for the GP7200 engine used on the Airbus A380 and the forthcoming PW GTF
series of engines was decided in favor of Pratt & Whitney. This
decision clears the way for P&W to continue to move forward with its
GTF engine program.
Rolls-Royce, PLC and Pratt & Whitney are partners in
International Aero Engines, who make the V2500 engine for the Airbus
A320, have seen their relationship deteriorate recently. Pratt &
Whitney, after discussions with Rolls-Royce, determined that it would
market its GTF engine itself, rather than through IAE, and with the
Rolls-Royce RB285 design gaining no traction with aircraft
manufacturers, Rolls-Royce now appears to be left out of the narrow body
market, with the CFM Leap-X and PW1000G the engines of choice for the
next generation of aircraft.
As the relationship hardened, Rolls-Royce
took legal action against Pratt & Whitney for alleged patent
infringement regarding the design of engine fan blades. That case,
which would have had major financial implications for each firm, has
been decided on summary judgment in favor of Pratt & Whitney.
The infringement suit focused on the GP7200 and forthcoming GTF
designs. Rolls-Royce had patented a design that had three different
sweeps in different direction to minimize airflow turbulence caused by
the fan inside the engine. Pratt & Whitney, in developing the fan
for the GP7200 engine produced by a joint venture of Pratt & Whitney
and GE Aircraft Engines for the A380, also utilizes a sweep design, but
in four directions. The court has decided that the differences in the
blades are such that no infringement has occurred, and decided the case
on summary judgment in favor of Pratt & Whitney.
As a part of the settlement for this case, P&W also agreed to a
voluntary injunction not to utilize a three sweep blade on the
forthcoming GTF engine series. Since it does not utilize such a design
anyway, this injunction will ensures that the GTF program will not be
slowed by any potential appeal of that litigation.

The implications are significant:
1. Pratt & Whitney did not infringe, and this lawsuit will not
hold up the development of the GTF, which is scheduled to enter service
on the Bombardier CSeries in 2013, the Mitsubishi MRJ in 2014, Airbus
A320neo in 2015 and Irkut MS-21 in 2016.
2. The GP7200 engine for the A380 does not infringe upon proprietary
Rolls-Royce design, and will continue to take a significant portion of
the A380 market, including the single largest customer for that type,
Emirates.----------

Bonjour !

Il est en général admis, que les "Coeurs" des bons moteurs "Civils" doivent beaucoup à des développements militaires, un peu apprivoisés pour le civil, Cf le couple CFM56/F101 !
Pratt & Whitney, actuellement navigue un peu "A vue" dans les futurs programmes de développement militaires ... entre F135-136, et a perdu des contrats de développement Govt clé , comme HEETE et ADVENT au bénéfice de GE !

Flight Global, bien renseigné nous sort un article des plus intéressants !
P&W, à développé sur fonds propres un proto de moteur militaire intéressant ! le PW 9000, quasi en secret !
Lequel est fortement inspiré des développement des coeurs de GTF ! à commencer par des compressions totales de 50, un niveau pas encore vraiment vu dans le civil, ni dans le militaire !
Une intéressante retombée vers les militaires ... tout en notant quand même que HEETE, propose des compressions qui vont vers un assez extravagant taux de 70 !
QQ lignes aussi sur le micro-cooling, un petit secret de fab de P&W breveté il y a 2 ans seulement !

Intéressant de noter, que P&W, que parfois l'on tenait pour incapables de chauffer assez pour assurer le développement et surtout les perf"s de leurs moteurs récents, se remettent soudainement dans la course, pour faire chauffer et monter la pression dans la marmite !

Bien, P&W déclare que, même hors programmes de développement, les technologies financées deviennent d'un accés publique, mais on peut quand même penser que ceux qui les développent ont acquis une sérieuse expérience et un peu d'avance !

Bien, c'ést juste assez intéressant, pour expliquer, les qq annonces, qui filtrent de temps en temps de P&W et qui concernent les possibilités de développement, et les marges de progrés des GTF, quand P&W annonce jusqu'à 20% de progrés, d'ici 2020 ... ça devient plus crédible, le PW1100G à 50 de compression micro coolé Basketball !
J'ajoute, que dans l'échelle des craintes possibles, je vois plus les PB venir des roulements de paliers de l'arbre HP, avec un coeur trés chaud, miniaturisé, et à trés haute vitesse, pale plutôt que de la partie réducteur ! Wink
Avis gratuit à RR, la barre (Benchmark) sera haute en 2018 alien !

---------------------- Le lien Flight Global, et un extrait ---------------

http://www.flightglobal.com/articles/2011/05/31/357304/pw-gears-up-for-next-generation-military-engine.html

P&W apparently believes it has solved this challenge with a
technical breakthrough called microcircuit cooling and tip blowing. In a
two-year-old patent, P&W engineers Francisco Cunha and Jason Albert
claim that the microcircuit approach is "the most advanced cooling
technology in existence today". In AFRL documents dated 2008,
microcircuit cooling is credited as an outgrowth of the F135 programme.
The PW9000 is likely to benefit from both the higher OPR of the GTF
compressor and the microcircuit cooling approach pioneered by the F135,
among other critical improvements.
However, it is not clear how the PW9000 compares with the
technologies in development by GE and Rolls-Royce for Advent and HEETE.
Whereas the GTF is credited with a top OPR of 50:1, GE has claimed that
the objective of its HEETE design is to achieve ratios up to 70:1.
Moreover, one of the key objectives of the Advent programme is to
introduce a third duct for bypass air around the engine core. Increasing
the ratio of air bypassing the engine core also reduces specific fuel
consumption at high speeds. However, P&W officials have argued that
the benefits of a third bypass stream have been over-hyped.
As government-funded research, data gathered during Advent and HEETE
demonstrations by GE and Rolls-Royce would be made available to other
bidders anyway, says P&W.

P&W confident in GTF maintenance support plan

By Mary Kirby

Pratt & Whitney
(P&W) is confident that the maintenance support strategy it is
putting into place for its geared turbofan (GTF) engine will satisfy
airline customers of the Bombardier CSeries, Airbus A320neo, the Mitsubishi Regional Jet and the Irkut MS-21.
At the Farnborough air show last year Qatar Airways
boss Akbar Al Baker said a CSeries order hadn't come to fruition due to
the airline's concerns over P&W's maintenance cost guarantees
. Asked
where the engine manufacturer stands on the issue now, P&W
commercial engines and global services president, Todd Kallman told ATI
and flightglobal: "We continue to work with Bombardier and I think we
are in a good position. But think about the fact that we were able to
show both Lufthansa, which has its own maintenance organization
, and
IndiGo, a low-cost carrier, that we have a better value proposition on
the A320neo engine than the competition. I think that was huge. We have a
good strategy in place. We'll have a network that supports us.

Bonjour à tous

La drôle de position de PW

Bloqué par les exclus sur le 737, le 777 et l'A350-1000
Bon ne pas oublié pour les "vieux modèles" les ravitailleurs du pentagone.

Une porte de sortie avec un A330 remotorisé ?

http://airinsight.com/2011/09/12/pratt-whitney%E2%80%99s-dilemma/


With Boeing choosing to proceed with a re-engine for the 737, Pratt & Whitney is out of luck. The exclusive supplier contract between Boeing and CFM means CFM retains the re-engining rights to the airplane.
Last March, Mike Bair, VP for future programs for the 737, told us the contract with CFM did allow for the prospect of switching engines. A competing engine had to have better economics and the commercial terms had to be better than the technical details and commercial terms offered by CFM, which had the right to match or exceed those offered by a competitor. Boeing’s assessment of the CFM LEAP, PW P1000G Geared Turbo Fan and the Rolls-Royce RB282/285 were that economics were about equal. Naturally Bair would not comment on commercial terms.
That CFM is the engine choice for the 737 MAX is no surprise; it was theirs to lose. PW all along figured it had little chance of participating in a re-engine scenario and RR bowed out of this game a year April with Boeing or Airbus.
But for Pratt, the market realities don’t end there.
Boeing and GE have an exclusive supplier’s agreement for the 777-300ER (and the 777-200LR) which likely precludes the prospect of PW developing an engine for the 777X. Indeed, the discussion we hear both through our own sources and through others with their own sources is that Boeing is talking with GE about a variant of the GEnx that powers the 787 and 747-8. The engine would have to be upsized to the 100,000-110,000 lb thrust class. PW’s GTF can grow to 110,000 lbs but if Boeing and GE are married, then what about Airbus?
We thought the prospect of a GTF for the A350 family, particularly for the A350-1000, might be a good alternative engine to the RR Trent XWB under development. But with Airbus and RR announcing an exclusive supplier agreement for the A350-1000 at the Paris Air Show, kiss this opportunity good bye.
Can PW develop an engine for the A350-800/900 which doesn’t appear to be covered by an exclusive agreement? Certainly, in theory. But not for some time. PW said it’s not interested in a large-class engine for many years, concentrating instead on the A320neo family.
So what’s left?
A real long-shot might be a prospective re-engine of the A330, which is aging. Although the A330 got a second life as a result of the 787 delays and has proved to be a remarkably resilient and efficient aircraft—particularly with Airbus extending the range of the A330-200 to as much as 7,200nm—Boeing is planning a 787-10 derivative aimed squarely at the A330-300 and counting on once the 787 finally enters service, the life of the A330-200 will be limited.
The CEO of AirAsia is pressing Airbus to re-engine the A330. So far, at least in public, there is no interest from Airbus—but Airbus also downplayed the prospect of re-engining the A320 for two years.
A re-engined A330 with a GTF is an interesting prospect, as this column as written before. The A330 is larger than the 787 and can carry more passengers and cargo. If Airbus could shave 10%-12% off the fuel burn—and thereby extend the range of the -200 and the -300 by another 500nm (roughly the amount the neo adds to the baseline A320), this would be an interesting airplane indeed.
And it would be the only realistic new opportunity for PW to extend its GTF technology beyond the 70-200 seat markets any time in the foreseeable future.

Sur l'A330NEO, il y aurait la compétition immédiate de dérivés des T1000 et GenX qui sont dans la bonne gamme de puisssance

PW finalise les accords avec ses partenaires sur le programme Purepower

Avec pour le PW1100G 41% pour MTU et JAEC

http://www.aviationweek.com/aw/generic/story_generic.jsp?channel=aviationdaily&id=news/avd/2011/09/29/06.xml&headline=JAEC,%20MTU%20To%20Collaborate%20With%20Pratt%20On%20Engine%20For%20A320NEO


Long-time International Aero Engines partner Japan Aero Engines Corp. (JAEC) has signed on with Pratt & Whitney for a 23% risk-revenue share of the PW1100G engine that will power the Airbus A320NEO, and MTU Aero Engines is increasing its stake in the program to 18%. To mark the collaboration agreement with JAEC and MTU, which will have a combined 41% stake, Pratt is renaming the engine the PW1100G-JM.

MTU, which also is a partner in the IAE V2500 engine with Pratt, JAEC and Rolls-Royce, will retain its 15% share on two of the other geared turbofan (GTF) programs, the PW1200G, which will power the Mitsubishi Regional Jet, and the PW1400G for the Irkut MC-21. But according to MTU, its previously agreed 15% share on the PW1500G engine for the Bombardier CSeries will increase to 17%.

MTU will be responsible for the PW1100G-JM’s low-pressure turbine and the first four stages of the high-pressure compressor (HPC), brush seals and a part of the HPC nickel blisks, MTU says. The company also will be responsible for final assembly of up to one-third of the engines. An MTU official says it still is not clear where the engines will be assembled, but most likely in Munich or Hannover.

The program work share has been the subject of lengthy negotiations that were originally expected to have been completed by the Paris Air Show in June. MTU was ultimately successful in securing more work.

JAEC, which also has a 23% share in the IAE V2500 program, will be responsible for the PW1100G-JM’s fan, low-pressure compressor and combustor/diffusor, Pratt says. JAEC is a consortium of Japanese companies IHI Corp., Kawasaki Heavy Industries, Ltd., and Mitsubishi Heavy Industries, Ltd.

Accord entre RR et PW

- RR vend sa part d'IAE à PW, mais reste dans la boucle pour de la prod...
- RR et PW vont collaborer pour les moteurs du futur dans le segment 120-230 PAX... et pour commencer sur les GTF !
- RR va s'investir un peu dans le moteur du NEO

On revient donc à un duel sur ce segment

Sacré news !


PRATT & WHITNEY AND ROLLS-ROYCE ANNOUNCE RESTRUCTURING OF IAE COLLABORATION AND NEW PARTNERSHIP TO DEVELOP NEXT GENERATION ENGINES
FOR MID-SIZE AIRCRAFT

• Pratt & Whitney to purchase Rolls-Royce share of International Aero Engines

• New joint venture with Pratt & Whitney and Rolls-Royce to develop new engines for future generation mid-size aircraft

1. Rolls-Royce and Pratt & Whitney restructure IAE participation

EAST HARTFORD, Conn. – Oct. 12, 2011 - Pratt & Whitney, a United Technologies Corp. (NYSE:UTX) company, and Rolls-Royce, the global power systems company, are pleased to announce a restructure of their participation in IAE International Aero Engines AG (IAE), which produces the V2500 engine for the A320 family of aircraft.

Under the terms of the agreement, Rolls-Royce will sell its equity and program shares in IAE to Pratt & Whitney for $1.5 billion. Pratt & Whitney intends to discuss a possible offer of a portion of these shares with its IAE partners MTU Aero Engines AG (MTU) and Japanese Aero Engines Corporation (JAEC). In addition, Rolls-Royce shall receive an agreed payment for each hour flown by the current installed fleet of V2500-powered aircraft for fifteen years from completion of the transaction.
Under the continuing leadership of Pratt & Whitney, JAEC and MTU, IAE will continue to deliver the same high-quality product and customer support without interruption. Rolls-Royce remains committed to IAE and its customers and will continue to be responsible for the manufacture of high-pressure compressors, fan blades and discs as well as the provision of engineering support and final assembly of 50 percent of V2500 engines.

Since its creation almost thirty years ago IAE has become a major force in international aviation with approximately 4,500 V2500 engines in service and approximately 2,000 on order.

2. New Joint Venture

Pratt & Whitney and Rolls-Royce also announced an agreement to form a new partnership to power future mid-size aircraft (120 – 230 passenger aircraft). The two companies will establish a joint venture company, in which each will hold an equal share, to develop new engines for the next generation of aircraft that will replace the existing mid-size fleet. The new venture will draw on the most-advanced technology from two world-class companies to drive enhanced performance for this fast-growing segment in which worldwide demand for around 20,000 new aircraft (or nearly 45,000 engines) is predicted over the next 20 years.

This new joint venture will focus on high-bypass ratio geared turbofan™ technology. In addition, the venture will collaborate on future studies for next generation propulsion systems, including advanced geared engines, open rotor technology and other advanced configurations.

The new collaboration brings together complementary technological resources and is designed to offer the best, most competitive response to customer demand for the next generation powerplant in the mid-size segment. The collaboration could bring about significant value for customers, as both parties are able to benefit from each other’s strengths.

The new joint venture between Pratt & Whitney and Rolls-Royce also benefits from the success of the V2500 and the PurePower® engine in establishing a broad customer base. It builds on the long-standing and successful partnership between Pratt & Whitney and Rolls-Royce in the mid-size segment. JAEC and MTU, partners of IAE and the PurePower® PW1100G-JM (Geared Turbofan™) engine program for the Airbus A320 New Engine Option (neo), also intend to join the new collaboration.

“Today’s announcement charts a clear course for the future of Rolls-Royce in the important mid-size aircraft segment,” said Mark King, president, Civil Aerospace, Rolls-Royce. “We are building on many years of successful collaboration with Pratt & Whitney in this segment to develop advanced aero engines, which we are confident will set new standards in aviation technology, performance and fuel efficiency.”

“These agreements position Pratt & Whitney, JAEC, MTU and IAE to best serve the needs of their customers for all A320 aircraft family,” said Todd Kallman, president, Commercial Engines & Global Services, Pratt & Whitney. “We are delighted to collaborate with Rolls-Royce with its complementary capabilities as we look forward to the next generation of aircraft engines that will offer even greater operational and environmental benefits.”

In addition, Rolls-Royce will make a modest financial investment in the PurePower® PW1100G-JM (Geared Turbofan™) engine for the Airbus A320 New Engine Option (neo) program.

The transactions announced in this release are subject to various closing conditions, including regulatory approvals.

Bonsoir !

Ca ressemble à une capitulation (Raisonnable) en rase campagne pour RR, qui enfin tire les conclusions !
Il y a 18 mois, les conditions auraient été meilleures !
Il aura fallu l'arrêt (Pardon, la suspension) du projet 797 pour enfin dénouer la crise ...
Au passage P&W récupère la capacité de production dont ils ont besoin !
John Rose va faire oops , dos d'âne, qq part sur sa moto !
Le principe du GTF überalles (Pourvu que tout marche!) GE/Snecma vont souffrir !
Et l'apport de RR quand même apprécié, pour une futur développement, c'est bien, ça vaut qq points de mieux !


Collaboration dans le futur, jusqu'à 230 pax !
Comme un petit goût de positionnement sérieux de P&W-RR pour le re-nouveau 797, aprés 2020 !

Bon en y repensant en me rasant :

D'une certaines manière ça peut être IAE sous une nouvelle forme pour l'Open Rotor,
On peut aussi noter que 230 PAX c'est plus que l'A321 Wink qui plafonne à 220 PAX
On peut imaginer aussi que le fait que RR vende sa part dans IAE et ne réinvestisse pas immédiatement (comprendre dans la même annonce) dans le GTF lui permet de trouver du cash pour faire autre chose

Pour PW, avec cet accord c'est pas mal, et avec Goodrich maintenant dans le giron d'UTC, il va y avoir grosse force de frappe technique
Reste le volet financement.

Pas sûr d'adhérer à la "capitulation en rase campagne" mais je dirais plutôt une reprise des choses en main pour RR qui a loupé un train, mais ne souhaite pas rester à quai

J'aime bien cette analyse

http://www.flightglobal.com/news/articles/r-r-stands-by-development-strategy-after-signing-gtf-joint-venture-363354/


Rolls-Royce is joining forces with Pratt & Whitney to apply geared turbofan (GTF) technology on next-generation engines, but the core of the UK-based manufacturer's long-term development strategy remains intact, a senior executive told Flightglobal.

Work will continue on R-R's three next-generation engine concepts - the two-spool Advance2 for the mid-size aircraft sector, the three-spool Advance3 for large aircraft and the open rotor engine, said Mark King, president of R-R civil aerospace.

The GTF technology, which P&W has pioneered with the PW1000 engine series, now becomes a key piece in R-R's development strategy.

Next generation engines will demand ultra-high bypass ratios and large fan diameters, King said. As fans increase in size, it becomes more efficient to slow the rotation of the fan in relation to the low-pressure turbine spool. Indeed, R-R's strategy may come to depend on gear technology for the Advance2 and open rotor engines to achieve their efficiency goals.

"I don't see this [joint venture] as a major change of strategy," King said. "I think I see it as a natural extension of our strategy and an elegant solution."

But relations between the two engine rivals on P&W's GTF strategy have not always been so cozy.

In May, R-R lost a lawsuit accusing P&W of stealing fan blade technology for the PW1000 series. R-R executives also have not been shy about criticising the strategy embraced by P&W, Airbus and - more recently - Boeing to re-engine the narrowbody fleet rather than shift to a clean-sheet design.

King said that R-R's criticisms were focused on a particular application - not against the value of the GTF technology.

"You've not heard me discounting the geared turbofan strategy," King said. "I have always said I like our partnership with Pratt & Whitney, and I have always said I would like to find ways to work with Pratt & Whitney in the future."

The two members of the joint venture have not decided on the division of manufacturing roles for next generation engines, King said.

Separately, R-R and P&W have agreed to restructure the International Aero Engines consortium, which makes the V2500 turbofan for the Airbus A320. P&W will pay R-R $1.5 billion for its equity stake and make payments to R-R for 15 years based on the number of hours flown by the installed base.

That agreement means P&W is the majority owner of V2500 engines for A320 and PW1100G for the A320neo.

It is an arrangement that "provides a common interface across the new members of the A320 family", King said.

Le PW800 va bénéficier de l'Advance 2
L'advance 3 va bénéficier à qui ? au 230 places ?
Et le GTF est une solution élégante !
SIC

Je pense que les commandes de CSeries vont se mettre à pleuvoir avec une telle pub

Oui Poncho !

Les 230 pax ressemblent un peu au nouveau futur 797, le seul gros projet en vue et qui pourrait démarrer quand même dans 2-4ans en open rotor... hum!
J'aurai quand même les regrets que RR n'ait pas signé il y à 18 mois pour le GTF, dans le cadre IAE, on aurait gagné du temps sur les A320, et peut être 2-3 points de SFC, car P&W à part avec le réducteur et le VAN, n'est pas vraiment en avance sur les autres technos, c'est d'ailleurs pour celà que tout le monde pense que le GTF a encore une forte marge de progrés !
Et RR serait resté à bord chez IAE, dommage !

Je reprends aprés te lire Poncho !
C'est sur qu'un Advance 2, en version GTF, ce serait bien intéressant ! Joignant le meilleur des 2 constructeurs !
Et que l'Advance 3 dans ce cas resterait dans les vraies htes puissances 60 000 lbs etc !

Noter aussi que le V2500 ne prenait plus guère de cdes depuis la sortie du NEO, l'accord devenait donc plus facile, surtout que l'ego de John Rose n'était plus au centre du PB (C'est moi qui le pense ...)

Un petit résumé en français


* Pratt versera $1,5 md à Rolls-Royce pour sa part dans IAE
* Désaccords stratégiques entre les deux groupes
* L'action Rolls-Royce à ses plus hauts

Pratt & Whitney a dit mercredi qu'il consacrerait 1,5 milliard de dollars à racheter la part de Rolls-Royce RR.L dans le consortium International Aero Engines, qui construit les moteurs équipant les Airbus A320

Cette décision est le résultat d'un désaccord stratégique entre Pratt &
Whitney et Rolls-Royce. Le motoriste américain a jeté son dévolu sur un
nouveau moteur appelé Geard Turbofan.

Les deux motoristes ont également déclaré qu'il formerait un partenariat pour concevoir des
moteurs destinés aux avions qui remplaceront les nouvelles versions des
Airbus A320 (A320neo) et Boeing B737. Pratt, filiale d'United
Technologies UTX.N , et Rolls-Royce auront part égale dans cette nouvelle entité.

Les marchés ont salué cette annonce, faisant bondir le titre Rolls-Royce à
ses plus hauts historiques. Vers 09h00 GMT, l'action prenait 6,79% à
668,5 pence à la Bourse de Londres après avoir touché 684,5 pence en
début de séance.

International Aero Engines (IAE), créé en 1983,
regroupait les deux motoristes ainsi que des associés allemands et
japonais afin de faire concurrence à CFM International, une coentreprise
franco-américaine entre General Electric GE.N et la Snecma, qui fait à présent partie de Safran SAF.PA .

Les deux alliances sont en concurrence sur l'A320, tandis que CFM a un
monopole sur le B737. Ces appareils de moyenne capacité constituent
l'ossature de la plupart des compagnies aériennes et sont la source de
commandes de moteurs et de pièces détachées à foison.

La décision d'Airbus de proposer le Geared Turbofan et un moteur concurrent
de CFM pour son A320neo a provoqué une poussée des ventes et incité
Boeing BA.N
à annoncer cette année son intention de proposer un 737 remotorisé
appelé MAX. Mais Rolls-Royce a opposé son veto au nouveau moteur, vendu
par l'intermédiaire d'IAE.

Les deux sociétés ont toutefois démenti qu'IAE, qui a plus de 4.500 moteurs en service et 2.000 environ
en carnet de commandes, prenne fin sur une rupture.

"IAE ne s'est pas terminé sur un divorce. Rolls-Royce restera un associé à part
entière d'IAE pendant encore 15 ans au moins", a dit à la presse Mark
King, responsable de l'aéronautique civile du motoriste britannique.
"Les deux sociétés disent qu'elles veulent travailler ensemble à
l'avenir en dépit du fait que nous ne participons pas à l'(A320) neo
".

Dans le cadre de la restructuration d'IAE, Rolls-Royce continuera de
fabriquer des pièces détachées et assurera la moitié du montage du V2500
qui équipe les A320.

Merci Art Way !
C'est quand même un peu curieux cer Allez Retour un peu dugâchis qq part !
Bien, il faut entendre que le V2500 se terminera dans qq années , et que le moteur suivant, il faudra le gagner , dans qq années aussi et le fabriquer, et on parle pour dans10 ans à ce niveau !
Les % de participation, certainement aussi vont évoluer !
C'est donc une solution d'attente pour le projets, et un run off programmé pour IAE !

La demande d'Airbus pour une présentation commune du GTF par IAE aurait dû être suivie par RR, une grosse erreur !
C'est du passé maintenant !
Les marchés saluent la remise en ordre, c'est bien !
Et les trent XWB vont bénéficier de plus de disponibilité de RR, tant mieux !

QQ réactions complémentaire, dont airbus qui ne semble pas mécontent d'avoir un second protagoniste qui peut assurer la continuité entre IAE et le Purepower

“I think it is excellent news,” says Airbus executive vice president for programs, Tom Williams. “It will help in marketing campaigns for the NEO,” the A320 new engine option offering.

For customers that want the standard A320 and the NEO, CFM International – the General Electric/Snecma joint venture – was able to offer package deals, now IAE can do the same. “Up to now Pratt & Whitney were at a disadvantage,” Williams says, noting that has now been fixed.

Oui, Airinsight, vu par Ferpe sur A.net (Je ne l'ai pas encore reçu!)

Une bonne compil comme d'hab !

http://airinsight.com/2011/10/13/pw-rr-partnership-what-it-means/

Un extrait !

The collaboration means that PW and RR will gain the best of both worlds
from their respective R&D efforts, and the ability to capitalize on
each other’s strengths. Clearly, PW has a winner in the GTF, which is
the first of the new generation engines for narrow-bodies. But as we
all know, engines don’t stand still, and PW has set an aggressive target
for improving the engine by 1% per year over the next decade
.
Leveraging Rolls Royce strengths and R&D, along with PW’s own
gearbox and research, should better enable them to achieve that goal.

Bonjour !

Ces lignes de Leeham, Scott Hamilton !
Bien intéressantes !


Plus de synergie ... les morceaux sont donc enfin recollés pour les A320 !

A lire :


  • Buying RR out of the International Aero Engines partnership gives PW
    far more latitude in making deals for the V2500 engines and the ability
    to connect V2500 transactions to transitions to Geared TurboFan orders.
    RR had no incentives to make connected deals, since there was nothing
    in it for them if a customer ordered the GTF instead of the V2500. CFM
    had the competitive advantage in offering the CFM56 for legacy airplanes
    and the LEAP for the A320neo. With PW now controlling the V2500
    partnership, PW has come closer to leveling the playing field.
  • PW has greater flexibility to wheel and deal on competition
    involving only the V2500. It was widely reported in aviation circles but
    never confirmed that RR’s recalcitrance to go along in one A320 legacy
    engine competition caused one customer to switch from V2500 to CFM56 in a
    follow-on order situation.

  • Sam Pearlstein of Wells Fargo observes, “We believe this should be a
    high return investment because UTX is making use of foreign cash that
    would be subject to repatriation, it is gaining a larger share of a
    long-term spare parts stream and it clears up customer confusion for the
    selection of engines for A320 & A320NEO airplanes.”
  • Pearlstein also observes, “By consolidating the IAE venture, we
    believe it makes for more simplified discussions with airline customers
    for both existing A320 and A320NEO orders essentially prior to this
    agreement, Rolls-Royce’s interests would have been to sell more V2500
    while Pratt & Whitney preferred selling more PW1000G’s. This now
    makes for a more unified approach to selling engines to existing
    customers, new ones and conversions, in our view.” This is reflected in
    other quick analyst takes.

Salut beochien

Moi je retiens ça


Airlines like engine choices, and Boeing’s exclusive arrangement with GE on the 737NG and Max may come back to haunt it in the future. Maintenance costs for the LEAP are likely to be significantly higher than those for the GTF (each manufacturer’s comparisons against today’s benchmarks indicate a 20% difference in favor of GTF) and with a stronger potential for future savings using the GTF technology through performance improvement programs, the GTF should have a significant economic advantage over leap in the 2020-2025 time frame.

Les coûts de maintenant du GTF plus faibles de 20% par rapport au Leap
A voir la confirmation
