As with the “A-11,” this concept was painted by an artist named de Beek while at White Sands in 1946, under the direction of Werner von Braun. It is clearly the ancestor of WvB’s later “wheel” space station concepts used for the Collier’s and Disney series of pro-space propaganda throughout the 1950’s. Unlike the “A-11,” this one seems fairly practical. It was to be at least partially inflatable, launched collapsed and expanded once in orbit. The specifics, however, are currently vague.
It rotated to generate “artificial gravity,” a feature that, at the time, everybody just knew would be pretty much mandatory for a manned space station. The effects of extended freefall on human physiology and human phychology were entirely unknown, and left to pure guesswork. As it turns out, “everybody” was pretty much right: zero gravity is fun for a little bit, and good for some science experiments, but it’s a terrible way to actually try to live.
The solar power generator is kinda unique. Keeping it tracking the sun while the station rotates around it might have proven to be a challenge.
Once again, more on this and related designs can be found in issue V5N6 of Aerospace Projects Review.
