These auctions for some of my cyanotype blueprints end tomorrow. Most have no bids, so if you want ’em they should go for cheap. These are some of the BIG blueprints.

I’ve put five of my large format cyanotypes on ebay, with starting bids far lower than the usual selling price.

I tried to scan some documents tonight, and the results were rather disturbing. I’ve seen this sort of thing before, but now it’s *really* bad. What could cause this, and can it be fixed… or is it time to take this scanner out into the woods and use it for target practice?

Note the lines. They *should* be straight. The paper original has straight lines, and the paper itself is good and flat, so it’s clearly something in the scanner itself.

Got them done a little early this time, so here’s a review of what the APR Patrons will be receiving:

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

I have a number of new aerospace cyanotype blueprints available. Until I can repave the catalog page, I have slapped together a PDF catalog of the new items. Until Wednesday, I’m making these new 12X18 prints, as well as the earlier 12X18 prints, available. The earlier 12X18s are viewable HERE. The new items are in the following PDF file:

Cyan catalog addition 2017-10

If any are of interest, Paypal to the email address in the PDF file, and add a note in the order which items you want…. AND what your mailing address is (PayPal doesn’t automatically add the address to payments like this).

After Wednesday the prints will be again unavailable for a little bit while I retool and work on some things.

UPDATE: over for now. After some retooling I hope to have all the cyanotypes, small and large old and new, available for regular sale.

Now available: two new US Aerospace Projects issues. Cover art was provided by Rob Parthoens,

US Bomber Projects #20:XB-59 Special

US Bomber Projects #20 is now available (see HERE for the entire series). Issue #20 collects all the previously published articles and diagrams of the XB-59 antecedent designs and updates them. Additionally, more antecedent designs have been included as well as several designs that followed along after the XB-59. The biggest USXP publication yet!

USBP 20 includes twenty nine unique aircraft concepts (the usual issue of USXP has eight designs) from Boeing Models 484 and 701 showing how Boeing evolved the XB-59, their competitor to the Convair B-58 “Hustler.” Beginning with subsonic flying wings, the concept saw concepts both conventional and unconventional before eventually settling on Model 701-299-1, the final XB-59 design. This issue includes a half dozen Model 701 designs that followed along after the cancellation of the XB-59 program.


USBP #20 can be downloaded as a PDF file for only $8:



US Launch Vehicle Projects #04

US Launch Vehicle Projects #04 is now available (see HERE for the entire series). Issue #04 includes:

  • Space Carrier Vehicle: A US Army lunar rocket with 8 F-1 engines
  • Convair Reusable Helios: A stage-and-a-half monster with a gas core nuclear engine
  • Boeing Model 896-111: A 1980’s two stage transatmospheric vehicle
  • Project RAND Satellite Rocket 3-Stage: A 1947 satellite launcher
  • Convair Saturn V-R: An idea on how to make a fully reusable Saturn V first stage
  • Lockheed STAR Clipper: A 1968 stage-and-a-half lifting body Space Shuttle
  • Shuttle-C: The Shuttle derived vehicle design that came closest to being built
  • Titan III Growth/156-inch boosters: A more powerful version of the Titan III for Dyna Soar launch


USLP #04 can be downloaded as a PDF file for only $4:


Also recommended, these previous Specials:

US Bomber Projects #14: System 464L Special

USBP#14 brings together the competitors to Weapon System 464L, the first major effort in the Dyna Soar program. These designs were previously shown individually in prior issues of USBP; here they are brought together, with some updates, as well as a few extra diagrams and a section of diagrams formatted for 11X17 printing. This issue includes info and diagrams of the Lockheed, Republic, General Dynamics, McDonnell, Boeing, Douglas, Northrop, North American and Martin-Bell entries as well as their various booster systems. Also included are detailed diagrams of the ultimate Dyna Soar design, the 2050E.

USBP#14 can be purchased for downloading for the low, low price of $6.

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.

The PDF file can be directly downloaded here:
