Model Forum / General / Models / April 2009Ju-52 - Only aircraft to use corrugated skin?
Nothing else comes to mind - any advantage to using this type of metal skin? Craig > Nothing else comes to mind - any advantage to using this type of metal > skin? > > Craig Well, let's see. The WWI Junkers D.1 and it's derivatives, plus the Junkers F.13 series of early passenger planes. The Ford Tri Motor and probably others that are lesser known.

It was used for increased structural strength.  SignatureAM http://sctuser.home.comcast.net http://www.novac.com vp@novac.com Stout Bushmaster, which was an update of the Tri Motor design. Quite a few small a/c use currugated skin on the control surfaces. Lots of Cessnas & Luscombes use this. > ctpmda...@comcast.net wrote: > >> Nothing else comes to mind - any advantage to using this type of metal [quoted text clipped - 21 lines] > > v...@novac.com >>> Nothing else comes to mind - any advantage to using this type of metal >>> skin?

I think on the Blackbird family it was used more to accommodate thermal expansion at M3 cruising speeds than for outright structural strength. >>>> Nothing else comes to mind - any advantage to using this type of metal >>>> skin?

There was expansion but wasn't same idea as Tri motor and Junkers. You look at the Tri Motor and the Junkers, its an airplane that would me fun to fly. or fly in. I know there were one or two Tri motors flying one on a regular schedule. Any Junkers? anybody know where they are? Tri motor was up in Minnesota somewhere I think. or Michigan. I think the F-105 was actually built by the Republic Locomotive Works. Ed knows better on this one. Rugged, will say that. Irregardless of the swill on C Span last weekend. > I know there were one or two Tri motors flying one on a regular > schedule. Any Junkers? anybody know where they are? Tri motor was up > in Minnesota somewhere I think. or Michigan. Almost exactly 5 years ago I was just on some new meds that were doing my head a bit. I heard a noise and stepped out the back door ( I live near a hospital, there's frequent helicopter activity and if its something unusual I sometimes wander up to take photos), looked up, and breifly through the one hole in the cloud cover this silver JU52 with a black nose and cowlings crawled across the sky. "O.K.," I thought, "That's Uncle Adolfs plane. This sh.t is making me delusional..." A couple of days later I found Lufthansa's Tante Ju was doing the rounds of the U.K., joyrides available. That was then. EEC regulations now prevent a lot of older aircraft carrying passengers since last year - I know a Dakota was giving it's final rides at Newcastle last year.

I recall that there was a Ford Tri-motor providing regular passenger service to some islands in Lake Erie. The plane was based in Ohio, perhaps around Toledo?

[quoted text clipped - 7 lines] > are lesser known. > Ol' 45 Stout, the designer of the Tri-motor, also did a few other planes using the stuff. Also, I believe there was a plane from a company called Hamilton that used the stuff. This was an attempt at stressed skin construction before folks learned to do stress analysis well enough. The discipline of stress analysis of complex structures was just evolving. Even with the equations, it took a computer to really do the job well, or many thousands of man hours. So folks just overdesigned. >Nothing else comes to mind - any advantage to using this type of metal >skin? More strength and structural integrity while using less material and bracing. The same reasons corrugated card board is corrugated. : Nothing else comes to mind - any advantage to using this type of metal : skin? There is also that Budd aircraft sitting at Pima. Anybody remember what it was? Never saw an aircraft designed by a rail road company before. After seeing that thing, I know why, too. And, no, Bombardier does NOT count!

I think one of Curtiss' biplane fighters had corrugated skin on the vertical tail. Bill Banaszak, MFE Sr. |
