Currently on eBay is a nice wind tunnel model set of parts for the Douglas D852. The design is not immediately known to me, but I suspect it’s an early 60’s concept, perhaps a very early TFX (eventually the F-111) or some other variable-sweep fighter. Anyone know?
Recently on ebay were a set of 8X10 glossies, vintage Convair artwork depicting early spacecraft and launch vehicle concepts. I had my bid in… and was sniped in the last few seconds. Oh well. Anyway, one of the more interesting images was this one of the Convair “Helios” developed by or for Krafft Ehricke… a chemical rocket first stage equipped with wings for glide recovering and a nuclear powered second stage with a “tractor” arrangement to separate the nuclear engine from the payload – essentially a small manned laboratory to land on the moon. The second stage would unreel something like half a miles worth of cabling and drag the payload along behind it, relying on distance rather than physical radiation shielding. The second stage would take the payload all the way to the lunar surface, gently lowering it down at the end of the cables, then land Way Over There Somewhere. A modern design would, I would hope, include electrical cables and would serve as a power generator.
A middling-resolution scan of the same image was posted back in January. One day I shall get a clean high-rez version. If that day is a particularly glorious day, it will come not only with the other images created for the Helios project… but they’ll also be in color.
No actual details.
An aircraft capable of Mach 4+? Sure, I suppose. Seems an odd thing to develop these days. Those sort of speed were an aviation fetish in the 50’s and 60’s, but there really isn’t a whole lot of need to go that fast and the penalties for doing so are *harsh.*
Operating in space? Meh. Might be a translation error or a simple misunderstanding. An aircraft capable of going that fast could potentially pop above the sensible atmosphere, perhaps like the X-15. So it would be in space, but nowhere near orbit (which would require Mach 25, not merely Mach 4). if it did so, it would need to have some ability to control its attitude, presumably with attitude control thrusters.
Or it could be BS. That would be entirely unsurprising.
Thanks to some APR Patreon crowdfunders, I was able to procure a *giant* blueprint of the Grumman F7F Tigercat from ebay. Today I got it back from the print shop where it was scanned at 300 dpi, resulting in an image more than 29,000 pixels wide. The image was processed a little bit to reduce the file size from 900+ megabytes down to 100, and a half-size version and a B&W version. These files have been provided to the funders. The blueprint itself will now be sent on to a relevant and worthy museum or archive.

In the 1960’s, sending space probes to Mars was a crapshoot; both the US and USSR lost very expensive spacecraft. This was due to one simple fact: spaceflight is hard. But in 1965, JPL engineer (John Casani) jokingly told a reporter that the problem was the Great Galactic Ghoul, a Mars-based monster that kept eating spacecraft. A few years later when Mariner 7 seemingly disappeared, a JPL artist (G. W. Burton) painted the Ghoul chomping down on the probe.
I’ve posted the full-rez scan (from an 8X10 B&W glossy) to the 2017-08 APR Extras Dropbox folder for APR Patrons ($4 and up level).
New to YouTube:
As a followup to the photos of the H-33 display model, here’s a Grumman report from July, 1971, giving a pretty good and well illustrated description of the H-33 orbiter.
The abstract on NTRS can be seen HERE.

The H-33 orbiter was designed in early 1971 to be launched atop a reusable manned flyback booster, a truly giant supersonic vehicle. The orbiter itself was similar in configuration to the Shuttle Orbiter as actually built, but it differed in that it had internal liquid oxygen tanks and expendable external hydrogen tanks, rather than a single large ET. The NASM has some good photos of a display model of the full system.
The H-33 was a popular design, at least at Grumman. A number of display models were made of it, including this detailed “cutaway” model made – seemingly – of plexiglas.
I have uploaded the full-rez images to the 2017-08 APR Extras Dropbox folder, available to all $4 and up APR Patrons. If interested, wander on by the APR Patreon and sign up. Lots of aerospace goodies available.
Currently being sold on eBay is a 4″x5″ transparency showing a Lockheed Skunk Works VTOL concept. I seem to recall this concept showing up in Av Week long ago… the 1990’s?
A few weeks back I posted an old Chrysler ad I found online. The image quality was ok, but kinda small. Subsequently I found a copy on ebay, bought it, scanned it and cleaned it. I’ve posted the full-rez, fully cleaned version of the ad to the 2017-07 APR Extras folder on Dropbox, available for free for all APR patrons at the $4 level and above. The full rez image is 4043×6270 pixels, or 13.5×20.9 inches at 300 dpi. It could probably be safely printed off at 200 dpi, giving 20.2X32.35 inches.
Here’s a dinkyscale version of the new scan:
And here, because I want y’all to know that these things take time and effort, are some full-size crops from both the final version and the raw scan, showing the improvement in image quality. Some of it is done via a few keystrokes, such as tweaking the rightness and contrast, but erasing thousands of little specks and fixing flaws? That’s all genuine artisanal hand-made old-school photoshoppery craftsmanship.
