This is the place where the majority of the warbird (aircraft that have survived military service) discussions will take place. Specialized forums may be added in the new future

I observe no degradation in quality - in short, great stuff!

For some reason, since about two weeks I am not seeing any of the photos posted on this forum. Am I the only one with this problem?
I guess I will have to log on from home and actually work with this computer.

WELL DONE armyjunk (as usual).
Some Notes on Gooses, Mallards and others ....:
No Mallards here, almost all Gooses with 2 views of the Widgeon production line (photos 9 & 10) and also some early F4F-3s for VF-4.
Number 11 shows 2TP 2H, the second of 4 Gooses for Peru.
Numbers 13, 16 & 21 show three views of one of the 12 G-21Bs for Portugal, identifiable by the top hatch aft.
These were the only Gooses to have this hatch.
The 12 G-21Bs were the only pure flying boats that Grumman ever built.
Number 24 has a regular G-21 and the first of 2 G-21C conversions done by McKinnon in 1958.
The 450hp P&W R-985s were removed and replaced by 4 340hp Lycoming GSO-480-B2D6s.
Not considered a sucessful conversion this airplane was converted again to the prototype G-21D Turbine Goose with 2 650hp PT-6s.
It was finally scrapped in the 1990s.
The second G-21C was sold to Pakistan as AP-AUY then went to Bangladesh as S2-AAD.
Last seen a few years ago, disassembled and in poor condition.
It was waiting to be returned to the US for restoration, no idea if it ever got here, it's not shown on the US register.

.Its time to repost this....These photographs came from the Archives at Grumman Memorial Park Calverton, Long Island, New York and The Cradle of Aviation Museum, Garden City, Long Island. My friend Leo Polaski spent many long hours scanning these........a right click and save will give you photo info. I hope everyone enjoys these These photographs do not belong to me
, they belong to the respective Museums ALL
permission to use these photographs in publications MUST
be obtained from the Museums, I ONLY
have permission to post here as long as no profit is obtained by me.
Its time for some Avenger photographs, first the XTBM, then the TBM-1 and then misc. Avengers which you guys can ID…..remember a right click and save will give you some Information XTBF's

I wonder why the skin is already all oil-canned with it being in the jig and not flown yet. You would think the factory would've figured out how to shoot aluminum skins on by then...or do you reckon they just didn't care on the "X" model?
Tue Jun 17, 2008 2:33 am
The skin is wrinkled because the fuselage section is being twisted in an 'iron monster' torsional load tool, and appears to be under a pretty significant amount of twisting moment.
This system was the next evolution in load testing airframes just after the earlier practice where structural load limits were determined by piling sand bags on the wings and tail until something went 'POW!'
The modern day equivalant is the gigantic jig set up to test the 787 wings and fuselage which uses very sophistocated computer programs to inflict the maximum amount of loading. Boeing is still undecided on whether to break the wings (the bet is there is so much flex the tip lights will touch) and perhaps run the risk of covering the three surrounding assembly bays in carbon fibre dust to a layer several inches thick, or just go to the required 154% of design, plus some fudge margin and call it good.

Cool info, thanks. For whatever reason, I just didn't think about manufacturers doing that kind of testing back then.
Tue Jun 17, 2008 3:32 pm
Nice, glad you all find these interesting. Sometimes I know what they are doing most times I don't......
