Re: Junkers Ju 52/3m engine mounting angle
Okay, the examples I will cite are from a Spanish version of the Ju 52, but I think they can safely be applied to most German-built aircraft as well.
Picture #1 will show that the nacelle and cowling ar indeed an odd (and misleading) shape. The nacelle is almost perpendicular to the line of flight, but the cowling does angle outward. The mating of the two is very strange, I had to stare at it a while to get it.
Picture #2 will show that while the center engine is perpendicular to the line of flight, the left engine does cant outward. This was shot from a distance with a zoom, which helps to eliminate the distortion found in close-up shots.
These pictures were taken of the Spanish-built Ju 52 at the US Air Force Museum in Dayton, Ohio.
