    Whilst it might be correct that this proposal would avoid the destruction of an entire village and bring 200,000 new residents into the airport’s noise footprint, can you imagine how unbearable it would be for those who already live within the airport’s noise footprint if they had to endure the noise that a doubling of the number of aircraft taking-off and landing would create?

    Aircraft noise is by and by large a solved problem now.

    The main issue is that the in-fleet aircraft largely lags behind the new (and thus very quiet aircraft).

    When the A320NEO, A350, A380, B737Me2, B787, B777X and CSeries comprise the majority of flights into and out of airports; noise complaints will reduce to a fraction of what they are.

    The F-35 IS a 5th generation fighter. It possesses stealth capabilities, AESA radar and thrust vectoring and can utilize a wide range of modern weapon systems. It is not the best multi-role 5th gen fighter out there, but it is indeed a 5th generation fighter and certainly could out perform a MiG-19. Your comments are very bold.

    Oooh… being very efficient with the truth there are we not?

    Lastly a MIG-25 was mentioned, as the USSR response to the B-70. When one was handed over to us in Japan, it was found out that it was so poor quality there was a placard on the panel that said “dont exceed mach 2.8”. Also its maneuverablity was in question. So how was a plane that was much slower and less maneuverable going to shoot down the B-70?

    The Foxbat’s AA-6 has a range of ~60km.

    The Foxhounds AA-9 has a range of ~120km for R-33E or 220km for the R-33S.

    The R-37 supposedly has a range up to 400 km. At Mach 6.

    16 typhoons, pooled across 2 squadrons makes sense, it could be argued perhaps for up to 20.

    In what world does it make sense to have 20x£100+ million tied up in completely unnecessary fighters?!?!

    You planning on changing your name to William Wallace and then invade England?

    Frankly, this SNP and their cohort are mad… They want to senselessly split the British Isles even more than they already are?! To what frigging purpose?!

    To have laws, taxes and systems more in-line with the needs of the local people rather than everything London-centric.

    Anyway, as regards their “defence force”. Forget about fast-jets. No need. If you don’t go around pissing people off, then you don’t need to drop bombs on anyone or intercept bombers/missiles heading your way.

    A few naval patrol boats. Some maritime patrol/SAR aircraft and boats, a reserve army and they are done.

    A must be fairly newish article on the Aviationist about the USAF RFI on lasers for its jets:

    At this point, they should ditch their new bomber in concept… unless it explicitly contains a sufficiently open design and architecture as to make incorporation of defensive DEWs relatively straightforward.

    Otherwise, by the time its in service (~2025-2030), it’ll effectively become a pre-dreadnought of the skies.

    SR-71 and MiG-25R proved that flying a zig-zag at M3 and 80k ft and will cause SAMs to run out of energy before they get to you.

    I would expect if bombers depending almost purely on high speed for evasion had gone into widespread service we’d have seen more SAM systems based off the RIM-8 propulsion philosophy.

    His logic was if a SAM could shoot down a U-2, they could shoot down a B-70 at 80,000 feet flying at 2000 mph. Of course that was totally wrong. A SAM with small guidence fins could not then and probably still cant stay in a turn with a plane like the B-70.

    For once, McNamara’s logic was totally right. The B-70 (and others like it) are not necessarily control surface or lift limited at these speeds and altitudes, but airframe limited.

    Also, a missile does not perform coordinated turns, so it is a fallacy to assume that similar geometric properties or proportions indicate similar performance. For example, any fighter has much less wing loading than an AIM-9X, but which will make the tighter turns?

    Given the introduction of RAMjet powered AAMs, fielding rocket boosted RAMjet powered SAMs is straightforward, so relying on speed to increase pursuit curve length and hence the endurance necessary to make an intercept is a losing game.

    I disagree strongly with Bill Sweetman on this one. The SR-72 is in my belief, the next battleground for the minds of the misinformed in congress (etc), so Lockheed can get yet more money from the US taxpayer. It is not a cost-effective weapons system.

    [Note, the F-111 was an abomination and a major misstep on McNamara’s watch.]

    easy.

    PAK-FA = No DSI
    F-22 = No DSI
    EuroFighter = No DSI
    Rafale = No DSI
    Gripen = No DSI

    F-35 = DSI
    J-20 = DSI
    J-31 = DSI

    The Gripen-NG may rule the skies with the other apex-predators if it incorporates DSI. Otherwise, its just another baby seal like the first 5.

    So you genuinely believe that flat nozzles reduce overall AB thrust by almost 20%.
    That’s okay. This thread has seen worse.

    It’d be around 9-10%. [If I remember right… but thats a long time ago and I had a lot of beer last night… :stupid:]

    in reply to: 777X? #503944
    Amiga500
    Participant

    Given that several variants of the A350 look to be bigger than the 787, is this an attempt to cover that particular size class?

    Yep.

    Does the 777X push the 747-8 out? I mean it would appear that the 777X is already gaining a lot of orders, so does that spell the end of the line for the 747-8?

    Yep.

    does anyone think Boeing will have killed their own product with the new 777X variants? Just curious.

    Why do you think they were so reluctant to launch the 777X?

    Airlines crying out for it for years and Boeing kept replying saying all their designers are tied up on 787… yeah… dead on. They’d committed to the -8 at that point and didn’t want to render it a dead-duck. They now recognise its a dead-duck anyway, so are going ahead with 777X.

    [although, in fairness, proving the technology on the 787 does allow the 777X to be de-risked]

    Current color scheme is just to test how well they can make it look like another aircraft.

    and it worked. very well.

    That is only a coincidence, i find it impossible to believe the Sukhois folks would lower themselves and gave attention to that horrible “fan-art”.

    Is it?

    There is a crank in the paint job along the “leading edge” of the tone switch, corresponding to the fan art.

    They also have aligned the trailing edge (including inconsistencies over the elevator) approximately the same as the fan art.

    Having a laugh? I think so. 😎

    Those engaged in testing them have a different view.

    They have ALWAYS had a different view though!

    The promises haven’t changed.

    The ability to actually deliver on the promises may have changed, but until there is an actual shooting war between two advanced adversaries of roughly equal capability, that will remain unclear.
