A photo of a wind tunnel model of a Republic Aviation design for a Manned Hypersonic Test Vehicle configuration. The photo was published in 1969, but the program was circa 1965. It used a configuration previously studied as both an Aerospaceplane (airbreathing SSTO) and Mach 10 recon. That latter design was written about and illustrated in US Research & Recon Projects #2. You can tell that this is the subscale demonstrator, rather than one of the full-scale operational vehicles, because of the additional fuel tanks, projection from the lower fuselage. The fuselage was conical and ringed with a scramjet engine; a rocket engine in the tail would, after separation from a B-52 carrier aircraft, accelerate the vehicle past Mach 7 or so to scramjet operational speed.

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.

  • Rockwell MRCC
  • Northrop Tacit Blue
  • Space Shuttle Main Engine
  • Boeing Bird of Prey
  • General Atomic 86-foot Orion
  • General Atomic Orion battleship

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.

I looked through a small fraction of my surprisingly vast pile of CAD diagrams for some I thought might look good in really large format. Some I’ve gone some distance towards formatting them that way already; some are still formatted for small sheets. There are more, of course. In no particular order.

Back in 2016 I released seven PDFs of CAD diagrams formatted for printing at 24X36 inches (those are shown after the break). This was another product line that didn’t exactly blow up the market, and no further diagrams were released. But now that I have two books of CAD diagrams released, and two more coming (and potentially more after that), I’m considering trying again. The Lockheed CL-400 Suntan, A-11, A-12, SR-71, YF-12, along with several B-47 and B-52 related designs are possible, as well as designs that aren’t from those books (X-20 Dyna Soar, several Orion vehicles, etc.). If this sounds interesting, let me know; if there is something specific you might be interested in, let me know.

The same seller trying to sell the Martin X-23 lithograph is also selling a lithograph of an orbital HL-10.

Turns out that these two lithographs are, at least based on stains on the X-23 matting, the same two lithographs sold just a few months ago. I’m dubious of turning around two lithographs that sold for $384 together for a grand or more each. The seller has a *lot* of high-value items… celebrity autographs and such, so he’s presumably doing well, but normally a lithograph like this would sell for well under $100.

Shrug.

Anyway, the art depicts an HL-10 coming in for a landing. The configuration includes a raised cockpit and reaction control thrusters at the tail; the white paint seems burned off along the underside. This would indicate an orbital craft after re-entry. Given the lack of an apparent hatch in the rear, this would not seem to be an operational orbital HL-10 (depicted hereabouts many times in the past) but instead a slightly smaller test vehicle, probably with a single pilot, possible lobbed on a once-around flight.

Recently APR Patrons/Subscribers and I were able to successfully crowdfund the purchase of a lot off ebay that included a few folders of vintage lifting body work. The chief prize from the lot was a *giant* blueprint of a “GTV Structure,” a manned Model 176/ FDL-7 lifting body test vehicle (“GTV” was not explained, but I suspect it means something like “Glide Test Vehicle,” designed to be dropped from an NB-52). Scanning of the lot is underway; the crowdfunders now have access to the blueprint in several forms (full size, halfsize; full color, grayscale).

HOTOL (HOrizontal Take Off and Landing) was a British Aerospace concept for a single stage to orbit airbreathing launch vehicle, originating in the mid 1980’s. It was a stellar example of aerospace optimism; like its contemporary the X-30 National Aerospace Plane, it relied on a propulsion system of spectacular complexity and stunning lack-of-actual-existence to function. As originally conceived it was supposed to have an RB545 engine; unlike the X-30’s scramjet engine, the RB545 was an air breathing rocket engine. Liquid hydrogen would be used to liquify incoming air, a portion of which would be turbine-fed into rocket engines to burn with the hydrogen. Due to some amazing bureaucracy, the engine was slapped with the “Official Secrets Act” which meant that it was so amazing that it had to be classified… so classified that it basically couldn’t be worked on. Genius! Whether it would have actually worked any better than NASP’s scramjet is anyone’s guess. In the going on forty years since the RB545 was dreamed up, it obviously hasn’t driven an aircraft to orbit. Or, it seems, off a runway. Like the scramjet, it *might* work, if only the development effort was properly funded and allowed to work through issues, rather than starved and throttled.

The early HOTOL configuration shown here would have taken off using a ground trolley in order to save on landing gear mass. The vehicle was nominally unmanned, though crew and passengers could be installed in a module in the cargo bay, located well aft. One problem the configuration had was substantial center of gravity and center of pressure issues, driven by the long, slim fuselage filled with sloshing and emptying hydrogen tanks. As memory serves, this remained a problem throughout the design lifetime of HOTOL.
