Corrugated skin adds stiffness in the direction of the corrugation. This means internal lengthwise stiffening is unnecessary (or can be minimized) and reduces the airframe weight, this is important if you are limited in available horsepower. The drag penalties are high and as aircraft performance (high cruise speed and reduced drag/fuel consumption) became more desirable to airlines smooth skin supplanted corrugated skin. The Ford Tri-motor was a much earlier and more primitive design when compared to the Ju52. The Ford "Tin-Goose was produced from 1925 to 1933, the Ju-52 entered production in 1932. As to being Hitler's preferred means of air travel, it was the only airline quality transport available during the war, aside from some outdated models from the twenties, and these generally had poor passenger accommodations.

The wings and fuselage are made of corrugated panels to add stiffness. But, wouldn't they also add weight and aerodynamic drag? Can we get an expert opinion about why airplanes abandoned corrugated skin?

Quite beautiful.

Was this taken in Sinsheim Technical Museum?

The JU 52 3M was Hitler's preferred form af air travel. Three radial engines and clad with corrigated steel panels it was an unusual looking aircraft. The American version was the Ford Tri-Motor
