Hi,

Would the airplane design of seating passengers inside airplane wings work?

Answer (1 of 16): Sure, if the aircraft was a flying wing. But few flying wing designs have proven to be practical, and those that have made it out of the experimental stage are all military aircraft. The B-2 stealth bomber is one example, designed as a flying wing to help minimize its radar sig...

Wow...

With eg the Boeing and Short designs ocean-hopping, how did the Germans end up with only the land-based Kondor and a couple of small-ish sea-planes ??

Germans had little reason to build such things. For what, direct travel to USA? To colonies? It was not economically feasible and there was little chance to sell their products to the French or British who had their own big flying boats.

Edit: I forgot to mention Dornier Do X, largest flying boat of the era. It was ultimately a financial failure, and not just because of the Great Depresion.

Found this in a newspaper archive (December 1926). It mentions a very large German seaplane liner for transoceanic travel. The wingspan would have been around 140 meters, plus a capacity of 150 passengers + 34 crew in luxurious accommodations. Luftfahrt History heft 8 also mentions this design, describing it as a 4-hull seaplane airliner. It was to be powered by 5 engines (2 in pusher, 3 in puller configuration). Neither source has any blueprints or drawings.

I the book Flying Wings by Rudolf Storck on p.20 it swtates that Kar; Grulich built large aircraft for Gothaer Waggonfabrik in (from ?) 1914. In 1919 he designed a 9 engine Nurflugel-Fluboot with boomerang shaped main wing.

In this thread, all the Grulich designs have ten engined. The term nurflugel / all-wing - ie, tailless might have been misused.
Main wing implies a tailplane. Boomerang shapoed wing appears to describe the Rumpler design.
Can anyone untangle this one ?

These are two separate, unrelated airliner designs by Karl Grulich. Of these the 10 engine one is a twin float, twin fuselage flying boat with unswept wings and a standard twin boom tail structure. The 9 engine design is the nurflugel which you mention. There is very little information on the latter project, but here is an excerpt from a 1945 article.

"K. Grulich, during the war of 1914 designer of the Gotha aeroplanes, a few years ago projected a huge Flying Wing flying boat with nine engines and a boomerang-shaped wing. One of its features was the arrangement of rudders and fins immediately in front of the nine pusher airscrews; the latter were placed above the trailing edge of the wing. (Weyl A, 1945)

Weyl A (1945), "Tailless Aircraft and Flying Wings: A Study of Their Evolution and Their Problems". Aircraft Engineering, Vol. 17 No. 2 pp. 41–46, doi: https://doi.org/10.1108/eb031217

Adler - thankyou for finding a definite reference to a Grulich flying wing.
His description suggests that he had seen a drawing but of course Weyl's writings were not 100% accurate.
Interesting and frustrating.
