As promised, now available are the first three of a series of articles from the original print run of Aerospace Projects Review… The Werner von Braun “Ferry Rocket” article from issue V3N1, the Lockheed Star Clipper from V3N2 and the Martin Astrorocket from V3N3. These are the original articles, converted from the Word files into PDF with no compression, additions or editing. More articles like these are coming, in order of original publication. See the comments HERE to see the list of forthcoming articles.
V3N1’s “Ferry Rocket” article is ten pages, and can be downloaded for $1.80.

Sorry, the comment form is closed at this time.
Scott, a couple of issues with the next blog post:
Both the pic and the comments extends beyond the edge of the screen AND any comments are autodirected to the paypal order form…
Hmmm, or that COULD just be really, really clever marketing on your part?
:o)

Yeah, I noticed. Something really screwy happened with the coding for the blog post. It’s always had a bit of trouble acceptign the Paypal button, but this time it made a real hash of things. I had to split the single post into three, and even then it kept throwing bizarre errors into the code. It shuffled HTML around, deleted lines, added lines of text…. grrr.
Hopefully this has got it.
(Should’a went with the marketing gimmick ;o)

You know, I’ve got some photocopies of all the performance details, weights and thrusts for that thing from the appendices of “Across The Space Frontier” if you would like me to send you one.

I have three copies of the book itself, and one of the reprints of “Das Marsprojekt.”
It’s interesting to see how the rocket’s design changed between “Das Marsprojekt” and the Collier’s articles; to the point where the rocket shown in the Collier’s series couldn’t actually physically contain the volume of propellants described in the math from “Das Marsprojekt”:

Hmmm…. I just clicked on the ADD TO CART button and it wasn’t added. One or the other of the others I bought was incremented each time I tapped the button, so that’s action. I’ll get back to this.
Add the charts and stuff Pat mentioned, and I’ll buy that, too. I’d do physical harm to someone to get wind tunnel test results. (Okay, really I’d just scowl at someone for them.)
One thing that shows up in those figures is just how severe the acceleration is during ascent (there’s a more detailed set of them in “The Exploration of Mars) At first stage burn-out you are pulling 8.9 g’s, and 8.0 g’s at second stage burn-out.
Acceleration was a big worry at that time. More than a few NACA papers from the postwar period concerned the effects. For whatever reason, it seems to have been expected that such a rate would be a Good Idea.
What were the rates for the capsules? I don’t recall anyone ever talking about that.
Isn’t “The Mars Project” and “The Exploration of Mars” in print — or at least available — now? I thought I found “Project” on Barnes & Noble’s website, a year or so ago.
Michael:
You did, they were reprinted and offered as a “set” about then. I picked them both up…
