    "Stealt materials."



    Costly corrosion problems on the F-22 caused by stealth materials and
    coatings have been addressed on the F-35, but risks remain, concludes
    a report by the U.S. Government Accountability Office.

    The GAO's presentation to Congress on its review of the DoD's
    corrosion evaluation report on the F-22 and F-35, completed at the end
    of September, says:

    "Corrosion of the aluminum skin panels on the F-22 was first observed
    in spring 2005, less than 6 months after the Air Force first
    introduced the aircraft to a severe environment. By October 2007, a
    total of 534 instances of corrosion were documented, and corrosion in
    the substructure was becoming prevalent. For corrosion damage
    identified to date, the government is paying $228 million to make F-22
    corrosion-related repairs and retrofits through 2016."

    That's the trouble with metal. It corrodes.

    It would have been far better to make the aircraft out of composite
    materials, otherwise known as "plastic".

    Really? B-52's flew for 50 years. Metal. F-4s, metal decades of
    use, F-16s, F-14s, F-15s, F-18s, C5s, etc, etc. Plastic did it to
    metal and if plastic was indeed a suitable material to use for 100% of
    the plane's construction, they might use it. But it isn't.

    Did you ever have a sense of humour?

    Have you ever smiled - even just once - in your sad little life?

    Has anything ever made you laugh? Would you know how to?

    I picture you with a permanent deep scowl. ;-)

    There are also two separate infrared camera systems onboard the F-35.
    The AN/AAQ-37 Distributed Aperture System consists of six infrared
    cameras placed around the fuselage of the F-35. Working together, the
    cameras create a 360-degree spherical image that can be viewed in the
    pilot¹s helmet-mounted display. The cameras provide the pilot with an
    infrared image equivalent to roughly 20/20 human vision, said Dave
    Jeffreys, Lockheed Martin¹s senior manager for F-35 Improvements and
    Derivatives. Additionally, these cameras also provide the pilot with
    missile warning, cueing of air and surface targets, and air-to-air
    situational awareness.

    The second infrared camera type is the Lockheed Martin AN/AAQ-40
    Electro-optical Targeting System, which is similar to the Sniper
    targeting pod mounted on the F-16 but is carried in an internal mounting
    in the F-35¹s nose. The camera provides very high-resolution video with
    a continuous zoom feature, which would be useful during nontraditional
    ISR missions in support of ground troops, he said. The camera will also
    provide the F-35 with long-range passive air-to-air search and track

    And the missles have cameras in their noses, some of them.

    Maybe the manufacturer should speak to the european automotive
    manufacturers who by and large have managed to make cars that resist
    corrosion provided they are maintained properly.
    Cameras made out of metal, planes made out of plastic and dresses made
    out of meat, my god it's madness, madness I tell you!!!

    I think my cat may be part methane.

    At this time, as some other manufacturers, they were reluctant to invest
    in electrocoating process. The result was a commercial disaster.

    The Alfasud and Lancias represented a low point in manufacturing
    quality of steel bodies. It was the unique combination of modern
    thin, high strength steels and the historic inability of Italian car
    manufacturers to prevent or delay rusting that led to those problems.

    It was a wake-up call for European manufacturers. Even Volkswagen's
    standards had slipped, and they led the way in inproving corrosion
    resistance by a combination of better design (avoiding rust traps),
    improved priming and painting and, especially, wax injection of
    cavities. Most of the severe rust problems were caused by internal
    rusting within cavities bursting through the paintwork, and the wax
    put a stop to this.

    Despite the fact that British roads have more de-icing salts applied
    to them in winter than ever before, rust problems are a thing of the
    past. There was some backsliding caused by the change from
    solvent-based to water-based paints, which brought added problems
    (especially to Mercedes-Benz), but almost every manufacturer selling
    cars in the UK now offers a warranty against rusting. It just isn't a
    problem any more.

    Ironically, among the brands whose bodywork is most resistant to
    corrosion is ... Alfa Romeo.

    I don't know about Lancia because the range was withdrawn from the UK
    market after the rust problems of the 70s/80s and never came back.

    Alfa Suds where the worst by far and IIRC had to recall them here in the
    UK as most where failing their first MOT (roadworthiness test done on
    cars from the third anniversary of registration). Since then they have
    improved enormously.

    I have just scrapped my 10 year old Alfa 156. Rust, among other things
    was on the MOT failure report.
    My financial loss does not upset me as much as the car being taken off
    the road.

    That metal corroded, too.

    Actually the whole program is corroded.

    The F-22 was originally supposed to cost between 90 and 180
    million depending on specs.
    The Pentagon and Lockheed (now Lockheed-Martin) agreed on a
    package for 120 million per plane, and then Lockheed went behind their
    backs and got the government to lower the specifications but leave the
    price as was.
    The Pentagon got wise and decided to cancel further orders,
    saying they'd just buy the F-35 (the "low cost" strike fighter that
    was supposed to be an adjunct to the F-22) and be done with the F-22
    Lockheed responded by saying that so much of what went into
    the F-35 was just scaled down from the F-22, and they needed to
    recover their research and development dollars, so they couldn't sell
    the F-35 at the originally agreed price of 60-some million per plane,
    and instead would have to charge the Pentagon 113 million per plane.
    The latest sale to Canada, with maintenance costs factored
    into the per plane equation will have Canadians paying more than 200
    million per plane for a plane that is about half as capable as the
    F-22, which was over priced at 120 million.

    Yes, but despite them having metal bodies, the IQ is just crap.

    Your subject title is just as incoherent, as its author is.

    Furthermore, "the nation's premiere fighter aircraft" isn't a product
    of >your< crummy country. The issues with Canada's military aircraft
    don't involve plastic...instead, the Canucks' "warbirds" are often
    grounded, because of engine faults (i.e., their rubber bands break).

    Few of the balsa/tissue model airplanes that I ever built,
    were capable of successful flight. Damned disappointing,
    considering all the time and effort I'd put into them.

    "Bruce" is an automobile authority, too! If only those aforementioned
    companies had known of his expertise, they could've employed him as a
    consultant...and hence, avoided such debacles.
    That's truly fascinating, old man. Obviously, Volkswagen hired you and
    heeded your sage advice.
    Yes, it's not "a problem anymore," for British-built cars. They simply
    fall apart >mechanically<, before having a chance to rust away.
    It was their own fault, "Bruce" -- they should've listened to
    you, back in the dark ages.

    Luckily, Olympus hasn't repeated that mistake, in these more
    enlightened times ("Bruce" speaks fluent Japanese and most
    camera makers seek his wise counsel).
