    What is the coefficient of drag on the F-35 vs. other aircraft, or are you just eyeballing it?

    Sorry, got to pull you up on this.
    The coefficient of drag does not say how much drag is actually produced. It is merely a comparison with the same frontal area expressed as a flat plate.
    A Formula one car has a high coefficient of drag but produces relatively little drag.

    The modern equivalents would be L163 for light work. This is generally easy to Cold bend or roll. For higher strength then L165 is normally used, which does not cold bend or roll.
    Alclad does indeed have a layer of pure aluminium to protect the alloy.
    Do you need some for a static a/c? It might be better (cheaper) to use a commercial quality, but use a reasonable quality alloy, not pure ally as it tends to bind.

    The US Defense Dept. doesn’t really want to purchase more Super Hornets as a stop gap until the F-35C arrives. So, I am sorry but I don’t see the logic in buying Typhoons especially considering the price! In that case the US would be better just buying more F-22’s. Even if it could afford say 25% less………..As for Tankers in the current economic climate I don’t seeing the KC-45 being viable……to bad.

    I think an awfull lot of projects are going to be put on the back burner for quite a while to come.

    Or the UK sells some Typhoon to the USAF as interim capability for the delayed F-35, in turn promises to buy more F-35 & uses F-18E as stop-gap in case the carrier is ready before the F-35 is.

    Only if they’ll buy our tankers as well:D

    Thanks for posting those. My father was there in the late ’40’s.

    Looking at it I would say it’s a shrouded turbine blade.
    The fir-tree root is a very common way if fixing them to a turbine disc.

    Hi Flyer

    Your cockpit lamp (Mk1A Dome) has been used in a whole host of aircraft throughout the postwar years also, in fact they were still “airworthy” in the Canberra PR9’s retired in 2006. They tended to be used in equipment bays and hatches (ie battery bay and rear fuselage on Canberras of most marks), and were used on the ceiling of the rear crew quarters of B and TT mark Canberra’s to provide general illumination in that area.

    I can provide the necessary bulb if you ever fancy powering the old thing up 😉

    Also known as servicing lamps by chance? If so, then the Victor was liberally outfitted with them.

    A good start would be the book “In Cobhams’ company” by Colin Cruddas.
    A fascinating read about Flight Refuelling Ltd.

    Then they have a claim, after all, wasn’t there a contract?

    At any rate, JSF is an entirely different situation than the tanker deal….the bottom line is that “the same argument” cannot be applied to ALL military purchases, least of all the JSF.

    I’m sure you know what you are talking about.

    Not really. The JSF program was completely different in that it had multi-national risk sharing partners that invested billions up front and have been extensively involved throughout the life of the project.

    But you knew that didn’t you? What is the term for people who knowingly post content with the express intent of provocation?

    I know of at least one European land that isn’t getting the share they were first lead to believe.

    For the second, two terms spring to mind. They are both user names.

    Exactly….

    Why is this so hard to figure out?
    It’s tax money.
    Not private money (like when I bought my Mercedes. I’m free to buy what I want without ruinous import duties).
    Not airline money (they can buy whatever will make them a profit or be at the peril of their shareholders).

    But when the government is buying something with tax money, it’s fair to spend as much of it in the country as possible…if for no other reason than to give employment to the aforementioned tax payers.

    The USAF should be free to buy the Airbus…but in return NG and EADS (hardly two charity organizations) should meet the Boeing level of U.S. content.
    I’m sure they can do so…especially with a 179 aircraft deal…we’re not talking about 4 Globemasters.

    The same argument could be applied to all military sales, the JSF for example…….

    Hi Rob;

    No mate, it’s my 1979 Suzuki GS.1000-E that I’ve owned since 1988 when it had a mere 8,000 miles on the clock, from new !!!!!!!!!!!!

    Ironically, I’ve got some pix somewhere of it parked-up not far from the Main-Runway inside Wattisham whilst it was still an RAF-Phantom base (1988)

    Wish they (F.4’s) were still flying around now; those were the days:cool:

    I’m running a 1986 GPz 750 and a Turbo at the moment

    Glad you said that = I did same when it was 1st posted & found same thing

    (i.e, nothing)

    Dialling in ‘search’ merely referred to some of the personnel’s prior involvement with Phantom’s during their service-careers

    I’d be interested to see the real ‘progress/link’, as a Phantom-Phan

    Hi, just interested in your avatar, is that a CBX?

    While I think the Canberra (and neither the Lightning) wouldn’t win a ceiling contest versus a Sparrow missile, would it?

    Depends on the height at which you fire the missile.
