    And if market blurb us correct they have not designed and made and engine on their own for 30 odd years. Last new engine was prob the v2500.

    Ooofft.

    That is probably stretching things just a bit too far…

    Lemme see.

    Trent XWB – A350

    Trent 1000 – 787

    Trent 900 – A380

    Trent 800 – 777

    Trent 700 – A330

    All post the V2500. While you could argue that the above are “just” derivatives of the RB211, that would be tenuous in the extreme!

    Indeed – you’ll struggle to find a recent new build LCA that doesn’t have Rolls-Royce options.

    it`s just that making assumptions without specific numbers is silly, and whatever the actual purchase price difference is you will want to compare to operating costs, per seat, etc.

    Those numbers will never be in the public domain. Ever.

    Even the list prices are just that… numbers on a list – they don’t have too much relevance to the actual prices.

    Airlines will have to balance the savings on the upfront purchase against greater risk in MRO, potential fuel savings/costs* and re-training in comparison to various other options.

    *which requires a fuel price forecast over the aircraft’s life. Anyone fancy speculating the price of kerosene in 15 years time?

    Yeah, I was trying to convey that RR is out of the market, but was speculating they may like a way back in, though who knows…

    I know RR have absolutely no plans to exit the single-aisle market, they have at least a couple of irons in the fire that I am aware of.

    They may not fight in this battle, but they are definitely not abandoning the war.

    With now 5 OEMs offering to the market (Airbus, Boeing, Bombardier, Comac and Irkut), engine manufacturers may start to go alone more than in conglomerates.

    Well sure, and I can see COMAC offering VEEERY nice deals just to build market share (and cerain discount airlines are extra glad to oblige). But it`s more that I don`t even see that argument being made… Perhaps it`s just the assumption, but it seems reasonable to expound on that assumption, right? …Backing it up with numbers comparison over life-time, etc…

    There are numbers out and about.

    At list price, an A320NEO is ~$95 million IIRC.

    An MS-21 has a target price of $35 million.

    The C-919 will have an even cheaper price.

    Could Boeing replace the tail assembly with new materials to make the aircraft lighter?

    They could.

    They could do an awful lot of things.

    However, the more you do, the more engineering time it costs, therefore the more expensive your 737NEO is going to be.

    Would it be worth the engineering time? As usual, it shrinks back to a cost-benefit analysis.

    Airbus were very strict on what NEO would comprise, to minimise engineering time needed for the mods. Boeing have to make more mods, and are having a harder time building their financial case.

    I believe that the open rotor is going to come a lot earlier than 2030… A lot earlier.

    I would really like to comment on this… but. 🙂

    Airbus is a step ahead in the development game and can position it self to counter Boeings counter moves easily I believe. Although admittidly it will have to get rid of the A400M some how as that seems to be a massive drain on its resources according to the FT.Com articles.

    I was of the opinion the A400M was a disaster, indeed, as a technical program, it still is a bloody disaster. However, I’m now firmly of the belief that A400M will eventually turn into a massive cash cow for Airbus.

    Look at the age of the current C-130 fleet… and the C-5 fleet… even the C-17 fleet.

    The only options in town are (1)another C-130 – which is hardly a significant advance over the current capability, (2) the AN-70, with its associated MRO problems and (3) the A400M.

    I wouldn’t pay too much heed to the market analysts – most of them are useless. While they may be right every so often, even a broken clock is right twice a day.

    But that wing box mod will need certification…

    Same boat as NEO (well, a wingbox mod is actually needed for the sharklets so the whole lot is getting wrapped into 1 as I understand it).

    It also still would not get over some of the skin crack issues that the 737 have identified would it? I guess boeing could completely redo the aircraft and ensure those crack issues are gone also.

    A change in Al alloys used, or a small change in rivet pitch would probably accomplish the same thing.

    2. Develop an all new 737 replacement aircraft for EIS around 2018-2020.

    So what do you do when propfan equipped competitors enter the market in ~2030 and have a 25% reduction in fuel consumption?

    Design another all new frame less than 10 years after delivering the first 2020 one?

    With some of the structural issues on the 737 coming up recently, and the apparently limiting wing height of the 737 meaning that it cannot fit a bigger diameter engine how will they be able to offer a new engine upgrade, with similar benifits?

    Leap-X supposedly fits, maybe with a nose gear mod.

    GTF will fit with a full landing gear mod.

    Both will need wing/wingbox/pylon mods anyway.

    Could you re-engine the 737 with an open rotor engine?

    Absolutely completely not.

    The biggest issue on the acquisition it not something John Leahy can control, and that’s the Unions.

    Can they dictate what aircraft an airline purchases? :confused:

    1. Depending on market segment, maybe.[*]No, that is a pipe dream for another 30 years anyway.[*]They may find themselves become marginalised if they don’t re-engine the 737. They may find themselves having to do two narrowbody designs within 10 years if they decide to go all-new.

    If Airbus does open a new line..why could it not be in the UK?

    New assembly lines cannot be opened if they cannot get enough components to assemble! 🙂

    Why is it I see the C-919 mentioned 10x as often as MS-21 in `Western` press, yet never any mention of what it brings to the table, besides the Leap-X engines and unremarkably modern avionics?

    Simples.

    90% of the aircraft for 50% of the cost.

    😉

    🙂

    So what hides the exhaust plume ejecting at > 1000K?

    The IR signature detected by IRSTs etc is not just, indeed, its not mainly the engine itself, or the combustor. It is the radiation from the hot CO2, CO and H2O that the sensors track.

    😎

    Erm.

    Those nozzles do nothing for IR signatures.

    Exact same on F-22.

    Shaped for radar purposes only.
