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.

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.

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.

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

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.

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.

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.

Every month, patrons of the Aerospace Projects Review Patreon campaign are rewarded with a bundle of documents and diagrams, items of interest and importance to aerospace history. If you sign up, you get the monthly rewards going forwards; the “back issues” catalog lets patrons aid the APR cause by picking up items from before they signed on. The catalog, available to all patrons at the APR Patreon, has been updated to include everything from the beginning of the project back in 2014 on up to February, 2017.

Below are the items from 2016 (and the first two months of 2017):

 

If you are interested in any of these and in helping to fund the mission of Aerospace Projects Review, drop by the APR Patreon page and sign up. For only a few bucks a month you can help fund the procurement, scanning and dissemination of interesting aerospace documentation that might otherwise vanish from the public.
