Mobile energy depot feasibility study: summary report

Description:

Declassified 28 Aug 1973. Various methods of producing and using nuclear power for military land vehicles and other military equipment were investigated and evaluated. A nuclear-powered mobile energy depot (MED) would move with advancing armies and produce vehicle fuels from materials readily available in the field. This would make mechanized units independent of external fuel supplies for extended periods, and permit them to move quickly and easily to areas impossible for units that depend on the customary fuel supply lines. Many possible MED systems were evaluated on the basis of energy sources, fuel manufacturing (by both conventional and chemonuclear processes), fuel storage and transportation, and fuel utilization in both present-day internal-combustion engines and power units of the future (i.e., fuel cells). The applications of more than a dozen MED systems to vehicular propulsion were studied.

The report can be downloaded directly from HERE.

Boats of the USAF

Recently uploaded into the APR Extras Dropbox folder for 2017-12 were a number of diagrams of United States Air Force rescue boats. Some of them were surprisingly large, given that the USAF is, you know, not about boats.

X-24 on a Titan III

A few days ago I uploaded in the 2017-12 APR Patron Extras Dropbox folder a scan of an old magazine article on the X-24 lifting body which including this interesting piece of art depicting an X-24 atop a Titan IIIc launch vehicle. There were indeed proposals to launch X-24 derivatives into orbit with Titan IIIs, but they wouldn’t be *exactly* X-24’s. The X-24 was not built as a spacecraft or a re-entry vehicle; it would be uncontrollable outside the atmosphere and would be a molten collection of rubbish on re-entry. Still, the proposed vehicles did look a *lot* like the X-24.

A bit of Martin Marietta artwork depicting the Titan IVA, rescued from ebay. I’ve put the full-rez scan (600 dpi, so it’s pretty big) in the 2017-11 APR Extras Dropbox folder, available to all APR Patreon patrons at the $4 level and above.

Bell Lunar Flying Vehicle

Back when NASA thought that the Apollo program would lead to more than just flags & footprints, they expressed an interest in ways for astronauts to get around on the surface. Along with rovers there were many designs for “flying vehicles,” basically “rocket packs” built into one or two-man platforms. Due to the lack of aerodynamic resistance and the lower gravity, performance of these systems was substantially less laughable than comparable Earthly systems.

Recently acquired from ebay is this bit of Bell Aerosystems artwork depicting a one-man flying platform designed to be carried by a Lunar Module. I’ve put the full-rez scan in the 2017-11 APR Extras Dropbox folder, available to all PR Patreon patrons at the $4 level and above.

Titan IIIC Artwork

A recent acquisition from ebay was a pretty good B&W glossy showing a Martin Company illustration of the Titan IIIC launch vehicle, circa August, 1964. One of the better Titan IIIC illustrations I’ve seen, showing the innards to good effect.

I have uploaded the full 600-dpi scan to the 2017-11 APR Extras Dropbox available to all $4 and up APR Patreon patrons. It’s in two formats… the raw scan, and a cleaned-up version that looks better. Also included is the press release printed on the back of the glossy. If you are interested, take a look at the APR Patreon and consider signing up.

Patrons will receive:

A proposal brochure on the C-135A cargo transport

A brochure about the Shuttle-C

A well illustrated NASA-produced booklet from the mid 1980’s describing the space station as them conceived

A large format diagram showing a wind tunnel model of the Titan III/Dyna Soar

A CAD diagram of the ca. 2001 Russian TsAGI Integrated Wing Body large passenger transport jetliner

F7F Diagram

Aug 232017

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.

The Great Galactic Ghoul

Aug 192017

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).

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.
