    Ca faisait qq temps que l'on n'avait pas rigolé avec RR, bien ....
    A part A et B qui ont encore qq avions sans moteurs sur les Parking , et qui rigolent un peu moins à mon avis !

    C'est bien, on se revoit après Le Bourget !
    L'avis de P&W pourrait aussi être intéressant d'ailleurs !

    Lu stricto sensu, du point de vue de RR (il est question du business case d'entrer sur le NEO pour RR et non du NEO lui même), cela me semble en fait plutôt raisonnable :
    - que peut il dire d'autre à ce stade ? le train est parti !
    - pas de moteurs prêts pour 2015, date actuellement envisagée pour l'EIS du NEO (les nouveaux triple spool RR, c'était plutôt pour 2017 ou 2018, si je me souviens bien) ;
    - pas de possibilité de venir s'ajouter à une gamme moteurs en cours de route, 3 ans après EIS de deux autres moteurs (trois moteurs pour un avion, c'est beaucoup, surtout si celui-ci risque d'être remplacé autour de 2025) ;
    - RR vise probablement le futur remplaçant du 737, et là, le business case sera clairement meilleur, avec plus d'années de ventes devant, et probablement seulement deux moteurs retenus (qui pourraient être RR et LeapX).
    Bref, déclaration plutôt logique pour moi...

    Merci McIntosh !

    C'est vrai que la formulation RR est exacte pour today le Business case, il n'y en a plus pour le moteur RR d'un A320NEO!
    J'ai bien relu, j'avais pensé que c'était le business case du 320 NEO ! (C'est ce qu'ils annonçaient avant)

    Il y a 2 ans pourtant Airbus aurait souhaité une offre IAE, un successeur au V2500, il y avait cette possibilité !
    Effectivement le train est passé, et ils devront compter RR, sur leur Advance 3, pas présenté encore, donc 2016 improbable, plutôt vers 2018 ... !

    Trop tard pour les A320 NEO , sauf une cata côté CFM ou P&W !
    Et sur quel avion le 797 ?? Un peu plus gros, donc effectivement plus dans les cordes du 3 arbres !
    Mais ... Rien n'est gagné d'avance , à ce sujet !

    Toujours possible un Advance 2 pour re-motoriser le 737 ..;
    Pourquoi pas, car je n'ai pas l'impression que CFM se soit beaucoup agité sur le PB ... et s'ils le lancent, un éventuel LeapX à plus faible diamètre, pour le 737, et après le LeapX du 320, ce sera assez loin (2017 ??) pour permettre à RR de raccrocher un wagon !

    Reste que P&W n'a pas d'usine pour fabriquer le P&W1100G ! et que Mirabel n'est pas dimensionné en ce moment, pour fabriquer et tester 80-100 GTF par mois !
    Et que IAE va avoir 2 FAL (Dont une dans le Connecticut) en chute libre dans 3-4 ans !

    Bonsoir Beochien,
    Effectivement, la production du GTF est une question à laquelle je n'avais pas pensé, et qu'il faudra examiner de près (dans le fil adapté).
    Pour le 797, j'espère que nous en apprendrons plus au Bourget, et que cela éclaircira ce que l'on peut attendre côté moteurs (en particulier, quelle gamme de poussées).

    Bonjour !

    Bien, pour les poussées du 797 ... cela va dépendre de l'oiseau !
    Mais entre 10 - 15 % de pax en plus, et autant d'allonge probable ... 3500 nm ++ à faible conso !
    Et 5-10 % d'écos sur les poids de structures... c'est un avion dans les 100 tonnes de MTOW que devrait sortir Boeing !
    Dans les 40 000 lbs max pour les moteurs !

    Une bonne opportunité pour RR d'essayer de placer leur "Mini 3 arbres" on attend ???
    Un petit "Sur dimensionnement" dans le domaine du "Scalable" assez facile pour P&W et pour le GTF !
    Peut être moins facile pour CFMI (Et peut être aussi hors du champ d'accords GE/SNECMA)

    Rolls-Royce Trent 1000 awarded FAA ETOPS approval
    By Andrew Doyle

    Rolls-Royce's Trent 1000 turbofan has been awarded 330min extended twin engine operations approval by the US Federal Aviation Administration.

    The engine is the lead powerplant for the Boeing 787 twinjet, due to enter service with All Nippon Airways (ANA) in the third quarter.

    R-R has meanwhile delivered Trent 1000s to Boeing to support 787 ETOPS test flights for approval of the engine/aircraft combination. It has also handed over a pair of Trent 1000s for the first 787 to be operated by ANA.

    Simon Carlisle, R-R Trent 1000 programme director, said: "ETOPS approval marks a major milestone for the Trent 1000 programme, setting new industry standards. We have produced the quietest and lightest engine for the aircraft, with the lowest fuel burn over the lifetime of an engine, contributing to the 787's target of delivering 20% less CO2 than previous generation aircraft."

    The Trent 1000, which ran for the first time in 2006, was granted FAA certification in August 2007, and has amassed more than 10,000h of ground and flight tests, said R-R. The engine powered the 787's first flight in December 2009 and has since powered 80% of all test flights. The engine equips five of the seven aircraft in the 787 flight test programme, and recently passed 2,800h of flight tests, R-R added.

    A Trent 1000 suffered an uncontained failure during ground testing in the UK on 10 August 2010, but R-R said a modification had been developed for later engines. However, Boeing last year blamed a lack of modified engines for causing delays to parts of the 787 flight test programme.

    General Electric offers its GEnx as an alternative powerplant for the 787.

    Rien à rajouter !
    Sinon, que P&W envisage d'utiliser un désign différent, à mon avis seulement si ils perdent, et les fan's en Plastoc, régleront probablement le PB "Foreign Object", tout en faisant gagner du poids au A380 !
    Etonnant que GE , Co-responsable du GP7200, se tienne en dehors ... apparemment, chacun son domaine dans le GP7200 !

    Bien, les remises clients, sont impressionnantes, autour des moteurs du A380 ! 70-80 % !
    Les vrais revenus sont à travers les programmes d'entretien ! Une forme de vente à crédit, ou de leasing indirect, enrobé dans les "Total Care " et autres, des définitions et des conditions de propriété, de moins en moins claires !

    Concernant la poursuite de 3,7 B$ de RR contre P&W. RR doit diminuer

    réclamer 493 M$ au maximum.

    On y apprend que RR vend les Trent 900 à un prix inférieur de 87% du
    prix de liste et que sans la compétition, ce rabais serait de 77%.

    Étrangement, il n'y a aucune mentions à propos du GTF.

    --------------------- J'édite le SFGate , pour info ------------------

    May 9 (Bloomberg) -- Rolls-Royce
    Group Plc must lower the $3.7 billion in damages sought in a patent
    lawsuit against United Technologies Corp.'s Pratt & Whitney because
    the jet- engine maker overstated the effect of competition, a judge
    ruled.

    Estimates for engine prices, units sold and the value of service
    contracts are "based on misstatements of the law, a lack of sound
    evidence, and unsupported economic assumptions," U.S. District Judge
    Leonie Brinkema in Alexandria, Virginia, said in a May 4 ruling.
    Brinkema didn't say what the damages can be should Rolls-Royce prove
    during trial that Pratt used a patented design for engine fan blades
    without permission.

    Rolls-Royce claims Pratt's GP7200 Fan Stage violates patent rights
    issued in 2000 for a Rolls-Royce Trent engine used on Airbus SAS A380s.
    London-based Rolls-Royce argued that it should be entitled to $1.35
    billion for the lower prices it said it was forced to charge on engines,
    plus $2.3 billion in profit lost because of engines sold by a venture
    of Pratt and General Electric Co.

    The list price for the Trent engine is $20 million, which was
    discounted an average of 87.3 percent to $2.54 million, the judge said,
    citing company data. She rejected Rolls-Royce arguments that without
    competition from East Hartford, Connecticut-based Pratt's GP7200 engine,
    the discount would have been 77 percent, for a price of $4.6 million,
    the filing shows.

    A damages consultant hired by Rolls-Royce "cannot just simply
    assume that airlines would happily pay millions of dollars more per
    engine," Brinkema wrote in throwing out the consultant's report. "It is
    not even clear whether Airbus would have undertaken the project of
    producing the Airbus 380 in the first place if it had only one engine
    supplier to rely upon."

    A spokeswoman for Rolls-Royce in the U.S., Mia Walton, couldn't be
    reached to comment. The company is the world's second-largest maker of
    jet engines, trailing GE.
    June 6 Trial

    The swept-fan blade design at issue in the case allows for a twist,
    giving the largest part of a jet engine greater resistance to damage by
    foreign objects, more stability and lower noise levels. The trial is
    scheduled to begin June 6, and Pratt is challenging the infringement
    claim.
    Pratt told the judge it plans to install different blades on further engines that design around the Rolls-Royce invention.

    "We are encouraged that the court has significantly limited
    Rolls-Royce's damages claim," said Jay DeFrank, a Pratt spokesman. "We
    believe this lawsuit is meritless and we intend to pursue the case
    vigorously."

    As an alternative to the $3.7 billion in damages, Rolls- Royce said
    it could instead be entitled to $1.3 billion as a lump sum of royalties
    owed. The company based that claim on interest from the consultant's
    estimate that a royalty agreement with Pratt would have been signed for
    $493 million in 2000.
    'Highly Speculative'

    Brinkema said Rolls-Royce could ask for $493 million at most, and
    Pratt can challenge that figure because it equals almost the entire
    amount Pratt invested in the joint venture with GE and is "highly
    speculative."

    Pratt in November filed its own patent-infringement case against
    Rolls-Royce with the U.S. International Trade Commission in Washington. A
    trial is scheduled for October before the agency, which has the power
    to block imports of products found to violate U.S. patents.

    The case is Rolls-Royce Plc v. United Technologies Corp., 10cv457,
    U.S. District Court for the Eastern District of Virginia (Alexandria).

    http://www.eglobaltravelmedia.com.au/airline/qantas-faces-further-roll-royce-engine-trouble.html

    Two of the world’s most reputable blue-chip brands, Qantas and
    Rolls-Royce, have been linked again after a Qantas flight to London was
    forced to return to Bangkok.
    The plane, a B747-400, was carrying 308 passengers when it
    encountered heat and vibration problems with one of its Rolls-Royce
    engines.
    Pilots shut the engine down, returned to Bangkok and landed shortly
    afterwards without incident, though passengers found their travel plans
    disrupted.
    In a statement carried by Britain’s Guardian and other media, Qantas
    said it believed “the cause is similar to events that other airlines are
    experiencing and is subject to an increased monitoring program from the
    manufacturer Rolls-Royce”.
    It was a Rolls-Royce Trent 900 engine that blew apart on a Qantas
    A380 after takeoff from Singapore in November, forcing the temporary
    grounding of the airline’s fleet. The Australian Transport Safety
    Bureau’s interim report on that A380 incident blames an overly-thin oil
    pipe for leaking and starting the fire that caused the turbine to
    disintegrate and send fragments ripping through the aircraft’s wing.
    A Rolls-Royce engine caught fire on a Cathay Pacific flight bound for
    Jakarta last week, forcing it to make an emergency landing in
    Singapore. Cathay and Rolls-Royce are investigating.
    Qantas’ Boeing 747 aircraft use Rolls-Royce RB211 engines. Respected
    aviation writer Ben Sandilands points out that the engines are now
    serviced at the Rolls-Royce facility in Hong Kong, since Qantas closed
    its specialist RB211 maintenance and overhaul shop in Sydney.
    Sandilands cites inside sources at Qantas as saying the former
    Sydney-based specialist RB11 unit used a more case-by-case approach to
    engines, taking into account the unusual long-range needs of Qantas
    operations, whereas the Hong Kong facility is more concerned with
    carrying out all the actions that Rolls-Royce specifies. The Qantas
    sources said there was no criticism of the quality of work at the Hong
    Kong facility.

    THE Trent XWB engine, designed and developed by Rolls-Royce in Derby, will take to the air for the first time later this year.
    At the Paris Air Show, Rolls-Royce's chief operating officer for civil aerospace, Eric Schulz, will tell the industry that the Trent XWB is the most efficient aero gas turbine engine ever produced.
    ------------

    Senior figures from airlines and the aerospace industry will also be briefed on the next generation of engines, including Advance3, a three-shaft turbofan engine under development in Derby. This engine is expected to enter service from 2018.

    For this year's inaugural Trent XWB test flight, the powerplant will be coupled to an Airbus A380 to evaluate its airborne performance.

    After a year on the test bed in Sinfin, the company says that it has beaten its targets for fuel consumption.
    A key part of the future of the aerospace operation in Derby, it has become the fastest-selling engine in the history of Rolls-Royce.

    The company is the sole engine supplier for the Airbus A350 XWB aircraft, which stands for extra-wide body, carrying up to 350 passengers. From the latest test results, Rolls-Royce estimates that, through improved aerodynamics, fuel consumption and lower weight per lb of thrust, airlines can save about £1.6 million per aircraft per year.

    R-R prepares to ramp up
    Trent XWB production

    Thanks to its status as
    sole engine supplier for the Airbus A350 XWB, Rolls-Royce is gearing up to
    build Trent XWB turbofans at the rate of almost one per working day by 2018.

    The engine - the largest
    yet produced by the UK manufacturer, with a 3m (118in) fan diameter - is being
    prepared for its first flight aboard Airbus's A380 testbed (MSN001) in the
    third quarter of 2011. A pair of Trent XWBs will subsequently power the A350 on
    its maiden flight scheduled for late next year.

    Although the Trent XWB's
    fan is only 51mm larger in diameter than that of the A380's Trent 900, Trent
    XWB chief engineer Chris Young points out that the smaller fan hub of the new
    engine means that each blade is 76mm longer and has 50% more surface area.
    "This is the biggest blade we've done by quite some amount," says
    Trent XWB programme director Chris Cholerton.



    Four development
    powerplants have already been run on the ground and double that number are due
    to be on test by July. Early results from the instrumented engines are
    encouraging, says Young.

    "We are beating
    expectations. Most of that benefit is in the compressors, which are performing
    very, very well. The compressors are demonstrating very high levels of surge
    margin - more than we need.

    "We're looking at
    whether we can trade some of the surge margin back into higher pressure ratios
    and better specific fuel consumption," he adds.

    The performance
    improvements could be introduced into flight-compliant engines ready for
    testing by the end of this year and yield an SFC reduction of around 0.25%,
    says Young.

    In addition to the eight
    bench development engines, one engine will be installed on the A380 testbed and
    another held as a spare for the flight-test phase. A total of 13 flight
    compliant engines will be supplied for the five A350 flight-test aircraft
    (including three spares). One more engine will be used solely for maturing the
    assembly process.

    Certification of the Trent
    XWB will be achieved "when we need to" ahead of the first flight of
    the A350, says Cholerton.

    "We've got three
    engines dedicated to maturity, in an attempt to have a higher level of testing
    prior to entry into service than we've had on previous Trents," he says.
    "The focus here is maturity at entry into service. Certification is just a
    step on the way."

    As part of the Trent XWB
    development effort, R-R has invested in what is thought to be the most
    powerful, real-time digital X-ray system in western Europe, which has enabled
    it to measure turbine blade tip movement relative to seal positions and
    identify oppportunities to boost efficiency.

    Previously, using
    film-based X-ray systems "we used to get four images in a day and take a
    long time to analyse them", says Young. "Now, we get 4,000 images in
    the same time, which we can run into a film and instantly be able to look at
    the data.

    "We originally started
    with four stages of variable vanes on the IP compressor. We're actually
    deleting one of those stages because we've had such good surge margin results.
    We were able to reduce the weight, cost and complexity of the IP
    compressor," says Young.

    He adds: "That puts us
    well on track to meet - if not exceed - our performance guarantees to Airbus
    from entry into service."

    Bird-ingestion tests are
    pending, with trials involving "medium" birds taking place in June
    and "large flocking" birds the following month. Another Trent XWB
    started endurance testing this month, and a further example will be used for
    cyclic tests from July.

    Cholerton says the
    uncontained failure of a Trent 900 powering a Qantas A380 last November did not
    lead to design changes on the Trent XWB.

    "We have a very
    different design style in the area of the failure and we're planning no direct
    changes in that area as a result of QF32," he says.

    A major focus for the Trent
    XWB programme is achieving production readiness, given the required fast
    ramp-up of the build rate.

    "Where we have novel
    manufacturing capabilities we have structured risk reduction," says
    Cholerton. "About 43 workstreams are manufacturing details which are
    different to those that we have previously executed reliably at rate [for
    previous Trents], so we take each of those through a structured risk-reduction
    process."

    For example, one component
    entering series production for the first time is the Trent XWB's three-stage HP
    compressor blisk.

    A dedicated pre-production
    facility is being set up to assemble flight-compliant engines and hone the
    manufacturing process.

    "The objective of that
    facility is to take the lessons from development build - which has some
    out-of-sequence work and a lot of instrumentation and suchlike - and
    standardise the assembly method with the objective of minimising the build
    time," says Cholerton. "That will be in place later this year and the
    first parts arrive for flight-compliant engines by the end of this year,"
    he adds.

    Full series production is
    due to get under way in late 2012 ahead of the A350 production ramp up in 2013.
    Some of the early production engines may also be assembled on the
    pre-production line.

    "It depends on the
    stability of the process," says Cholerton. "We'll exit pre-production
    when we feel we have a totally stable process, but nominally this will be the
    back end of 2012," says Cholerton.

    Although the Trent XWB's
    initial thrust rating for the A350-900 will be 84,000lb (374kN), the engine
    basic engine has already been run at 100,000lb-thrust in testing, well above
    the level required for the stretched -1000 variant of the airframe.

    "We do insert
    high-temperature technology into the engine [for the -1000]," says Cholerton.
    "A couple of the demonstrators which are helping to mature that technology
    are the Trent 1000-based Environmentally Friendly Engine demonstrator and the
    E3E two-shaft demonstrator, which gives us important information on the tip
    clearance control and the shroudless blade system that we will use on the
    variant of the engine for the -1000."

    The configuration of the
    growth version of the engine is due to be finalised in the first half of 2012.

    Bench testing of the
    baseline Trent XWB has underpinned work on the growth variant, says Young.

    PARIS: R-R details Trent 1000 roadmap as service entry looms

    By Andrew Doyle

    Rolls-Royce is preparing to power the Boeing 787's service entry with
    All Nippon Airways, scheduled for the third quarter, as it
    simultaneously starts work on a third package of improvements for the
    Trent 1000 aimed at the stretched -9 variant of the aircraft.Although
    certificated at a thrust rating of 74,000lb (330kN) in 2007, the
    "Package A" version of the Trent 1000 is rated at 64,000lb and will
    equip only the first four ANA 787-8s.

    The Japanese carrier's fifth 787 -the first to be operated on international routes and due to be
    delivered at the end of the year - will introduce the Package B version
    of the engine rated at 70,000lb."Going into service we're
    confident we've got a mature product that's had a lot of engineering
    work and issues fixed, and a lot of flight-test experience," says Trent
    1000 programme director Simon Carlisle.
    "Clearly the [787] programme has gone much slower than we would have liked, and the engine would have
    been ready back in 2007. I guess we'll never know what that would have
    meant."He adds: "No doubt, where we are today we've got a more
    reliable product, because we've had time to do a ton more testing on
    it."The Trent 1000 has accumulated more than 1,000 flights and
    over 2,800 flight hours, and flight testing of the first Package B
    engine began in May. Package B re-optimises the fan system around a
    different nozzle geometry, due to an earlier change in the thrust
    requirement for the 787. Also revised is the air system and low-pressure
    turbine (LPT).Trent 1000 chief engineer Andy Geer says: "I don't
    think it's any secret that both engine companies on the 787 programme
    adopted a very similar style of LPT - high lift, short, low weight, and
    both of us have had some challenges in getting full aerodynamic
    efficiency out of that.

    So we've both done an iteration of the design. Package B gets us back within 1% of [fuel burn] specification."The UK manufacturer is working with Boeing and ANA to ensure a smooth service entry for the 787. "I guess that will really start to feel real around the beginning of
    July when Boeing starts to do route proving," says Carlisle. "They'll
    take the aircraft to Japan and do a ton of testing. We're absolutely
    treating that as if it was active service."He acknowledges that lessons were learned from the introduction of the Trent 900, powering the Airbus A380, in 2007. "We've got higher levels of support stationed around the world.
    Initially it's quite straightforward for us because it's all Japan and
    domestic for the first few months.

    Once ANA take their first international aircraft then we'll start putting support into Europe and
    the west coast of North America
    . That's people, assets and spare parts
    backed up by the operations centre in Derby and Boeing's operational
    centre in Seattle."Carlisle also stresses the importance of getting the company's public relations strategy right."The thing we're very cognisant of from the A380 is being on top of communicating with the media.
    We're expect intense media interest in the aircraft. You can be sure that any squawk or cough will get a lot of
    attention, so we've been spending time on making sure that we will be in
    a position to handle that in the correct way," he says.

    R-R and rival General Electric - offering its GEnx turbofan for the 787 - have
    split the market roughly equally in terms of numbers of customers,
    although GE leads in terms of aircraft numbers.Geer says the
    Trent 1000 is within a "cigarette paper" of matching the GEnx on fuel
    burn, but the Trent's three shaft architecture will pay dividends in
    terms of better performance retention."Most of the focus on fuel
    consumption is on new engines," he says. "An engine is new once in its
    life and it spends the rest of its 24 years and 364 days not new and you
    should be more worried about its deterioration characteristics.
    He adds: "Over the full life, our experience is that the three-shaft
    engine is significantly better. But it's not always easy to sell that in
    advance."Another feature of the Trent 1000 is its intermediate
    pressure shaft electrical power offtake, which helps to reduce fuel
    consumption with the engine running at idle, particularly beneficial for
    short flight cycles.

    Next up are Package C improvements for the 787-9."We've
    just been going through our concept close-out review, so we're moving
    into the detailed design phase for the parts that will go into Package
    C," says Geer. "The Package C programme has moved around a bit so we'll
    continue to tune when we deliver those solutions to best match the
    aircraft we are delivering."

    Further away is Boeing's proposed -10X double-stretch, which would see the introduction of an extensively
    improved Trent 1000 which would then be offered across all three models
    of the 787 family. "We're just starting that conversation with
    Boeing so they're in the process of defining the aircraft and we're
    working closely with them to decide what the engine requirements are,"
    says Carlisle. "At the moment all of that fits well within the
    capabilities of the Trent 1000. One of our desires is to take some of
    the learning we're getting from the XWB and feed that back into the
    1000. We see these engines very much as sisters.
    Technology-wise they're very equal, despite their different architectures."Our goal here
    is to make sure that when we do that, we design an engine that covers the whole family.

    Once Boeing nail down their requirements for the -10X then we'll respond with our offering for the whole family."

    C'est une comm finalement tout pleine de modestie.
    Et très intéressante.

    Par contre on voit bien sur le trent1000 la différence entre les poussées certifiée en 2007 et celles finalement obtenues avec les différents packages

    A = 64000 lbs donc à priori MTOW réduite ?
    B = 70000 lbs
    C =
    Certif 74000 lbs


    On peut comprendre qu'une partie du boulot du package B peut être mis au débit de boeing (augmentation des poussées demandées et donc dégradations des performances en conso... cf Trent XWB et A350-1000)

    Rolls-Royce to address cost impact of Trent XWB decision through Total Care programme

    Rolls-Royce will address the maintenance cost impact of its decision
    to incorporate a new, scaled-up core in the Airbus A350-1000's Trent XWB
    - which eliminates commonality with -800/900's engine - through its
    Total Care support programme.

    The UK engine-maker had previously planned to base the A350-1000's
    engine on the 84,000lb thrust (375kN) version that powers the -900, with
    some material and fan module changes.

    But the larger core and other technical modifications eliminate much
    of the commonality.

    The new engine will not be interchangeable with
    those on the A350-800/900, even though that was the original intent.


    "The systems, interfaces and nacelle external lines are going to be
    common, as well as a lot of the accessories. So for the airline, the
    interface with the aircraft is going to look like the same Trent XWB,"
    said R-R civil aerospace president Mark King.
    "There is a lot of commonality in the supply chain and the systems
    and the bits that the airlines deal with on a day-to-day basis, for
    example the training.

    "It's only the off-wing stuff that is going to have the impact, where
    there is limited part-number commonality in the core, and we can take
    care of that under [the] Total Care [support package] as part of the
    solution."
    King said that the decision to go with a derivative rather than
    all-new design means the programme is lower risk. "Even the new core is
    not a redesign, it is a scale."

    Rolls-Royce aims to apply the technology to other members of the
    Trent family, and introduce a major revision to the Trent 1000 for the
    Boeing 787 within five years that will "open clear daylight relative to
    the competition", said King.

    "This engine will be more than an 'EP' [enhanced performance]
    upgrade, it will be a significant improvement for the Trent 1000," King
    said. "We hope to do it for a 2015-16 service-entry timeframe. To
    achieve that, we'll need to make some decisions in the next six months
    or so."
    King said that the intention is to read across technologies from the
    Trent XWB and Environmentally Friendly Engine demonstrator for the Trent
    1000 upgrade. "The technologies we're running on the testbed between
    the XWB engine and the demonstrator gives us a real opportunity to
    upgrade the Trent 1000."
    Potential changes could include modifications to the turbine, such as
    an additional stage or upgrades to the compressor. However, exact plans
    for the Trent 1000 are still being discussed both internally and with
    Boeing. "Within this process we're looking at a whole bunch of things,"
    said King. "We have a number of options, and we'll decide [on the
    changes] in discussion with Boeing.

    "The intent with this engine is that we are capable of addressing the
    787 derivatives that Boeing might decide to develop in the future.
    "

    Rolls-Royce and LM sign engine fuel efficiency agreement

    Rolls-Royce,
    the global power systems company, has signed a memorandum of agreement
    with Lockheed Martin Corp. to provide performance improvements,
    including better fuel efficiency, to the T56 family of engines. The
    agreement builds on a partnership of over 50 years and demonstrates
    long-term commitments from both companies to enhance safety, economy,
    reliability and performance of Lockheed Martin aircraft.

    Rolls-Royce has introduced technologies proven in its other business
    units for the Series 3.5 engine enhancement kit to give improved fuel
    efficiency, increased turbine life, and better engine performance for
    hot day and high-altitude operations. The redesign has demonstrated up
    to 9 per cent savings in specific fuel consumption during recent engine
    testing.

    The Series 3.5 engine enhancement kit is designed for retrofit into T56
    turboprop engines powering military applications, such as the C-130H
    military transporter and the P-3 military maritime patrol aircraft, and
    the commercial L-100 variant.

    It utilises technologies already in operation with Rolls-Royce powered
    commercial and military aircraft, such as new turbine blade materials in
    the AE engine family, as well as the blade coating process used in the
    501-K gas generator in our energy business. The Series 3.5 engine
    enhancement upgrade can be accomplished as part of a traditional engine
    overhaul, and does not require any aircraft or engine control system
    interface modifications.

    Patricia O'Connell, Rolls-Royce, President - Defence Customer Business,
    stated: "As operators continue to look for ways to extend the service
    life of their C-130, P-3 and L-100 aircraft, the Series 3.5 engine
    enhancement kit will offer them significant performance enhancements to
    enable more efficient operations for decades to come."

    Jim Grant, Lockheed Martin Vice President of Business Development for
    Air Mobility and Special Operations Forces, stated: "We are dedicated to
    supporting our legacy C-130 and P-3 aircraft that continue to provide
    outstanding service to the armed forces of the United States and its
    allies. This level of service is accomplished through long standing
    collaborations, such as we have with Rolls-Royce."

    C'est une redescente des technos de l'AE2100 vers le T56
    A priori y a une filiation directe entre les deux ce qui est plus facile


    Au passage


    Due to the identical physical fits and common thrust centrelines and mounts, in-service aircraft currently powered by the Rolls-Royce T56 turboprop engine can be upgraded to the AE 2100, giving operators increased thrusts and reduced life cycle costs.

    http://www.bloomberg.com/news/2011-07-18/rolls-royce-utx-s-pratt-settle-jet-engine-patent-dispute-1-.html

    Rolls-Royce Holdings Plc, the world’s second-largest maker of jet
    engines, settled a patent dispute with United Technologies Corp.’s Pratt
    & Whitney unit.

    Terms weren’t disclosed. The companies requested in July 15 court
    filings dismissal of two civil lawsuits against each other. The
    settlement also covers a related case before the U.S. International
    Trade Commission that threatened to delay delivery of Boeing Co.’s 787
    Dreamliner passenger airplanes.

    The companies “reached an amicable, confidential settlement agreement
    resulting in dismissal of all patent litigation,” East Hartford,
    Connecticut-based Pratt and London- based Rolls-Royce, said in e-mailed
    statements.

    Rolls-Royce had lost in May the case it brought against Pratt over
    engine-fan technology, while Pratt’s lawsuit had been on hold pending
    the outcome of the ITC complaint. Rolls-Royce makes the Trent 1000,
    which has been designated for Boeing’s newest passenger jet, and the
    Trent 900 for the Airbus SAS A380, which competes with the GP7200 engine
    sold by a venture of Pratt and General Electric Co. (GE)

    A federal judge ruled in May that Pratt’s GP7200 Fan Stage doesn’t
    violate a patent issued to cover technology in the Trent engine for the
    A380. Pratt’s lawsuit accused Rolls-Royce of unfairly using patent
    litigation to keep it from re-entering the biggest segment of the
    commercial-airline market. Pratt filed an ITC complaint in which the
    agency is investigating whether the Trent 900 and Trent 1000 infringed a Pratt patent.

    The ITC case is In the Matter of Certain Turbomachinery Blades and
    Engines, 337-751, U.S. International Trade Commission (Washington).

    The September case is United Technologies Corp. v. Rolls- Royce Plc,
    10cv1523, U.S. District Court for the District of Connecticut (New
    Haven). The earlier case is Rolls-Royce Plc v. United Technologies Corp.
    (UTX), 10cv457, U.S. District Court for the Eastern District of
    Virginia (Alexandria).
