Missed the Mustang (solved) ;-)

Seemed to be a Junkers (commercial) trademark, starting just after WWI...

But the JU 52 was constructed in 1934!

I don't know why though?

Corrugating the skin gives it rigidity & strength for less weight. A similar principle is still used on the aerofoils of more modern aircraft like the Cessna 172.

But what about aerodynamic properties. Obviously the JU 52 flies, but air when naturally flowing over a wing not only flows from front to rear, but it also wants to flow sideways along the wing to the tip.

I'm no aerodynamicist but it possibly helps to smooth out the airflow & stop that happening. This should make the wing more efficient, They use all sorts of devices like wing fences on other aircraft for the same purpose. Also don't forget that this was pioneering stuff. Junkers was the first manufacturer to use an all-metal fuselage & wings usng this concept back in 1916 when all other manufacturers used braced wood & fabric for many years to come. Ironically his first successful aircraft was a biplane. http://www.geocities.com/hjunkers/ju_j4_a1.htm

Here's a shot of the beautiful Lufthansa Ju 52 I took at Duxford Legends last month.


PS. Glad that you two met up & saw the Mustang. That's a result.

She made a fly past at Soest last Sunday too. Right now (edit, sorry shift work, it screws the head, it should be "this time yesterday) she was on the apron here at Paderborn
Today she is in Hannover.

Jap,it felt very good to look at this A/C.
The commentator was a little bit "sad" because the german JU had to be "modified" with "modern" stuff to get the flying license from the Luftfahrtbundesamt.
