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.

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.

And the HL-10 lithograph

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.

Currently on ebay is a lithograph of the Martin X-23 PRIME (Precision Reentry Including Maneuvering reEntry) subscale lifting body, a mid-1960’s program to build small test vehicles for the full-scale X-24A lifting body. This depiction shows it without the “bump” on the forward fuselage simulating the contours of the cockpit canopy. The seller is rather optimistic with a $1875 Buy-It-Now price, although he will consider offers.

Another copy of the same lithograph, along with a lithograph of an orbital HL-10, sold a few months ago for less than $400. That was too rich for my blood for two lithographs, never mind nearly two grand for one. Shrug. But at least the listing provides a fairly decent photo of the art. I *believe* I’ve only seen it reproduced in B&W.

McDonnell Model 176 Lifting Body Crowdfund Success

Jul 012022

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).

Boeing Model 733-606 art

The Boeing 733 is *reasonably* well known as the designation for the Supersonic Transport before it got re-designated the 2707. However, Model 733 was sort of a catch-all designation for a long (numerically and temporally) series of designs covering the gamut from giant Mach 2+ SST’s down to bombers, strike aircraft and fighters. The link seems to be that the 733 started off specifically as an SST designation; but other aircraft types were designed using the same aerodynamics. A fighter that was basically a scaled-down SST might be a model 733 (such as the Model 733-605). Shown below is a reasonably commonly reproduced piece of art from the 80’s depicting what is sometimes called the Model 606; it’s actually the Model 733-606. I’ve seen diagrams for a number of aircraft based on this basic geometry; the 733-606-11 and 733-606-12 were strike aircraft. The aircraft below is generally described as an interceptor, sometimes as a supercruise research platform.

Have you ever wondered to yourself “what were the Air Force Weapon System Designations as of September, 1959?” Wonder no more:

The following page does not continue the Weapon System list, but goes on to list Air Force ace fighter pilots.

“SIPS”

Jun 182022

Recently sold on eBay was a display model for a vehicle labeled “SIPS.” No other data was available. However, this appears to be an upper stage modification for the LIM-49 Spartan surface-to-air anti-missile missile. Which suggests that the first “S” in “SIPS” standard for “Spartan.” Perhaps something like “Spartan Integral Propulsion System” or some such. However, this seems to appear to be a complete vehicle…. the very large first and second stage motors, as well as the warhead section, *appear* to have been replaced with a new, small booster with fins. Perhaps this was meant to test the third stage of the Spartan… or perhaps it was meant to be a way to find some use for the Spartan third stage after program cancellation, as some sort of scientific test vehicle.

The other photos from the ebay auction have been uploaded to the 2022-06 APR Extras folder on Dropbox for Patrons and Subscribers.

The diagram below shows the complete Spartan missile.
