Some years ago I produced a range of cyanotype blueprints of a number of aerospace subjects. The hardware needed for this was disposed of when I left Utah at the end of 2019, so starting again seemed unlikely. However, someone has expressed interest in a special commission. Rebuilding the hardware needed will be an expensive chore, and sadly getting the large format transparencies printed looks like it will be much more difficult here than it was in Utah. Nevertheless, at this point it looks probable that I will restore that capability sometime in the next few months, assuming one further detail can be ironed out.

You can see my now-defunct catalog here:

When I get back to it I will probably focus on the larger format stuff rather than the smaller prints. I have plans on how to improve upon the prior hardware to make things work better and more efficiently. If there are any of the former large format prints you’d like to see returned to production, or you have any prints you’d like to see, let me know. And once this is up and running I plan on trying to take commissions, working with a local print shop to find customers interested in this somewhat unusual and certainly obsolete form of art.

 

If you have a diagram you’d like me to turn into a cyanotype, contact me. Commissions aren’t going to be restricted to aerospace subjects; naval, architectural, movie props, whatever you’ve got, so long as it *can* be blueprinted, once things are in place I should be able to do it.

A mere sixteen years ago I posted artwork of the Martin “EGRESS” ejection capsule meant to fling crew from a stricken spacecraft anywhere up to and including orbit. Those scans came from photocopies of a conference paper. I have at last now scanned the same work, producing slightly better results. The artwork is remarkable for one detail in particular: of the two crewmen, one is clearly Lance Squarejaw, wholly unfazed at his situation. The other is… not unfazed. I’d pay real money to get at the original color painting.

 

The whole thing – diagrams and art scanned at 600 DPI – will be offered up to APR Patrons & Subscribers soon.

Atlas launch to test inflatable heat shield

 

A United Launch Alliance Atlas 5 is scheduled to lift off from Vandenberg Space Force Base in California at 4:25 a.m. Eastern Nov. 10. The primary payload of the rocket is the Joint Polar Satellite System (JPSS) 2 weather satellite …

A secondary payload on the launch of JPSS-2 is Low-Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID), a NASA technology demonstration. While JPSS-2 will be deployed nearly a half-hour after liftoff, LOFTID will remain attached to the Centaur until 75 minutes after liftoff, following a deorbit burn of the Centaur.

Shortly before deployment, LOFTID will inflate a reentry shield six meters in diameter. That heat shield will slow down the vehicle from orbital velocity to Mach 0.7 as instruments on board collect data on the performance of the shield. LOFTID will then deploy parachutes to slow it down for the rest of its descent, splashing down in the Pacific east of Hawaii to be recovered by a ship.

Inflatable heat shields have been studied since before humans flew into space. Normal heat shields need to withstand insanely high temperatures, requiring materials that are either insanely expensive and complex, or that involve complex, fragile and heavy active cooling systems (such as water cooling through transpiration), or which are ablative. The latter variety is technologically fairly simple, but ablatives tend to be heavy and they are labor intensive to apply and make reusability difficult.

With temperatures reaching several thousand degrees, inflatable materials would seem inappropriate for heat shields. But those high temperatures are not a mandatory feature of re-entry. To a first hand-wave approximation, the maximum temperature is proportional to the mass-per-surface-area of the re-entry vehicle. A one-ton vehicle is going to have to shed all of its orbital velocity, converting all that kinetic energy into thermal, regardless of the size or shape or cross-sectional area. The way that is done is by compressing the air the vehicle slams into; the heating isn’t due to friction, but to the compression of the gas. If you can spread that heating energy out wider… the gas doesn’t heat up as much per unit surface area. Heating can be reduced from the sort of thing that will melt tungsten to the sort of thing that can be survived by advanced polymer fibers. As a bonus, the inflatable shield, being far larger than the solid shield on the vehicle, provides drag all the way down. In principle it would be possible to dispense with parachutes, wings, retro-rockets, and simply drift down using the shield as an inverted parachute. This was the case for the Douglas “PARACONE” concept from the mid-1960s, designed for, among other uses, as an emergency “life boat” for astronauts in space. It would provide for a safe entry, deceleration and touchdown on either land or water.

Art from 1966 showing the S-IVB stage as launched on the SA-203 flight of the Saturn Ib, launched July 5, 1966. This flight put an S-IVb stage into orbit and demonstrated engine restart in microgravity, needed on the upcoming Apollo moon missions.

I’m at work on a new series of CAD diagrams (see HERE for the first run) to be released as PDFs formatted for printing at 18X24. For example, here are first drafts of a few:

  • Boeing Space Sortie (3 sheets)
  • Saturn C-8/Nova
  • Jules Verne’s “Columbiad”
  • A-12 Avenger II (2 sheets)
  • Lockheed CL-400 “Suntan”

All of these require a bit more dressing-up, as well as explanatory text. But I think they’re starting to look pretty good.

 

 

I’ve selected a fair number more to work on. If any of these are of particular interest, or if any of the many, many diagrams I’ve made over the years would be of interest, let me know.

My third book, “US Supersonic Bomber Projects Vol 1” is, as I understand it, somewhere between “being printed” and “being shipped.” I am thus hard at work on Volume 2. I had hoped to also do a Volume 3, but that is unlikely: Volume 3 would be “Space Bombers.” However, apparently the market for “space” is nothing like what it is for “aviation,” so the idea has been nixed. There is official interest in several other works I’ve planned, so properly published books seem likely to continue for some time.

That said: while the market for “space” is less than the market for “aviation,” my own interest in the two is about equal. And I would be happy to sell works at a number substantially lower than a professional, proper publisher would. A publisher would have books on bookstore or grocery store shelves, while I would only sell from my little website.  And if I’m not incredibly stupid about it (no guarantee of that, of course), a self-published book would, theoretically, bring in more on a per-book basis than one done through a publisher. So I’m contemplating something like a Kickstarter for “Space Bombers.”

As currently laid out, this book would be almost overwhelmingly “The Book Of Dyna Soar,” as the bulk of (available) American space-based bombardment studies revolved around that program. However, it would extend well beyond Dyna Soar, including Orion and other strategic orbital weapons systems studied back in the sixties, on up through much more recent studies including aerospaceplanes and bombers based on the X-33/Venturestar/RLV studies. Being self published I would not be locked into a set page count and, perhaps, could include foldouts and perhaps more color art (depending on funding). This could be released as both an Ebook and a softcover… and, depending on length, a hardback. Other “extras” could include 18X24 or 24X36 prints of diagrams, perhaps on something like mylar.

I am *far* from setting up a Kickstarter for this. I’ve seen a lot of people get *really* mad about funding this or that project and then watching it slip far behind schedule, so I wouldn’t even start a crowdfunding campaign until it was substantially complete. There are a number of topic areas that I really want to delve into more deeply via FOIA and whatnot, a process that has become far more troublesome in recent years. At this point it’s in the “this is an idea to think about” stage. But I am interested in any input on the subject… thoughts on crowdfunding, ideas about subjects to add and, as always, input of documentation on the topic that you might have that you think I may not.
