    XB-52

    in Research Corner

    Posted

    I usually don't post museum pics, but this one of an F-89A at the old outdoor Air Force Museum near Fairborn held a little suprise for me when I got it scanned. Possible one of the last photos of the Boeing XB-52, hiding in the background. The slide date is early 60s and both the XB and the YB were unceremoniously scrapped as part of a "base beautification" program initiated by Ladybird Johnson in the mid 60s. How the **** do you "beautify" a museum by scrapping two unique historic aircraft in the collection? And don't start me on the YB-36 either....

    Enjoy

    I think the F-89 is an "A" model.

    Eurofighter term

    Exactly.

    Tranche 1 means the first production specification, Tranche 2 means second production specification etc...

    For our friends over the pond, when you hear 'Eurofighter Tranche' think 'F-16 Block'

    Great,Thanks for all the replies.I got a hold on it now.

    Eurofighter term

    It's a Collateralized Mortgage Obligation or a companion bond.

    In other words - all the countries that want to produce and/or buy EF2000s have shared investment intrests in the building of a predetermined number of aircraft. This is different from the "Block" or configuration type of the aircraft. A Tranche may actually purchase aircraft from several Blocks or configurations.

    BTW - There are Block 1 and Block 5 differences that I learned about when the RAF was here back in May. The Block 1 Typhoons have no IR ball to the left of the windscreen while the Block 5s do.

    AND - what ever you do - DO NOT call the "Fore-Planes" Canards! I heavily insulted one of the RAF Fairies by calling the Fore-Planes "Canards" . . . "It's not a bloody French aircraft afterall . . . "

    I'm still laughing over that one!

    ATB -

    - Rip -

    Here is an excerpt from the new Air international Typhoon insert:

    "Some 148 aircraft were built in tranche 1,the last of the core nations was delivered on March 20,2008, a German twin-seater.Austria is to receive nine aircraft from tranche 1 production, with five having been delivered by the end of 2007."

    It looked like they used the term to combine block numbers. And then they talk about up-grading Tranche 1 aircraft to tranche 2 standards.

    F-18 Oval Fuel tank

    Hey guys need a hand. does anyone know who makes the older oval shaped center fuel tank for the F-18B? I want to do a USNTPS bird and need the tank

    thanks

    Andy

    I asked that question before and never got a response. The oval tanks were never a production tank anyway.I've only seen FSD aircraft with the tank.Do you have a picture with a USNTPS that has the oval tank on it?

    USN F-4G

    Externally there is no difference between the F4G and the F4B. The G was used as a testing platform for the ILS system, any changes were internal. I think that there was only 12 G's made, and were all later converted back to B's after the system was adopted. As far as I know there are no decals available. Shoudln't be hard to make them, they were all camouflage at the time, two tone green and white underneath. All markings were very subdued, as far as I know there was no squadron markings. I hope this was helpful.

    There was one other difference.There was a retractable radar reflector in front of the nose gear under the nose.It was for the automatic carrier landing capability.

    B-2 Crash on Guam

    Heck, it looks pretty alien on the ground too. Glat the crew got out ok, that could have been much worse.

    It's to bad the ground photograper did'nt follow it to the end.

    F-15 pics needed

    AFAIK, it's one of two colors, either metallic blue-green, or white. The swap from the metallic color to white supposedly came around the FY80 airframes.

    I agree with Dave.I just found a photo in the book;Modern Fighting Aircraft F-15.These were those large yellow books published in 1983.Photo shows the production line sometime in 1980 and shows F-15C's with white TEWS area.I think some time in the early production run for the "C" they changed from green to white.

    YF-23 Question

    in Jet Modeling

    Posted · Edited by Steve jahn

    When I built my YF-23 I asked Paul Metz a member of my model club and the test pilot for YF-23 about that. He said that they decided to paint that door red for safety reasons as you mentioned. I guess that when the aircraft was shutdown this door would hang open, thus the concern about saefty when checking the under side of the jet. He said that the door was triangular in shape so they got the idea to add the second triangle thus creating the hourglass shape. He said that it lasted one flight which just happened to be the one in which the photo you mentioned was taken. After that the "higher ups" told them to remove it from the aircraft. The name "Black Widow" had already been given to the aircraft long before this, I was told that it was a tribute to the P-61. Next time I see him I will see if he has a copy of that photo.

    Look at 3:30 on this video. You can see the markings.
