1: A diagram of a proposed DC-9 aft propfan research configuration
2: A Kaman K-Max brochure
3: A preliminary draft/outline for a report on F-108 employment
4: A CAD diagram of the M61A1 Vulcan

Hey! Anybody hereabouts interested in unbuilt variants of the North American B-70 bomber? I know a guy who can hook you up:

A black and white bit of concept art that was sold on ebay a while back showing the Lockheed STAR (Space Transport And Recovery) Clipper space shuttle concept from the late 1960’s. This was a promising concept that used a lifting body orbiter with a wide, flattened rear fuselage that was liberally covered with rocket engines (a large range of engines and layouts were considered, including liner aerospikes). The shuttle was filled with liquid oxygen tanks and some hydrogen tanks; the bulk of the hydrogen was stored in a large V-shaped drop tank. This component would have been larger but reasonably inexpensive, jettisoned after deletion to be destroyed during re-entry or splashdown in the Indian Ocean. The vehicle would have continued on to orbit using the propellant remaining in the internal tanks.
A vast amount of information on the STAR Clipper is available HERE.
The STAR Clipper lasted a lot longer than many contemporary designs and went through a multitude of design revisions. it always seemed like it should have worked reasonably well… and it had the benefit of being aesthetically beautiful.
Rewards have just been posted for APR Patrons/Monthly Historical Documents Program subscribers. Included:
1: “Manned Aerodynamic Reusable Spaceship (MARS) Vehicle Design” a 1962 Douglas report covering a single stage “orbital airplane” of impressive size and design.
2: “Pretest Information 3.3 Percent 624A Aerodynamic Heating Investigation, NASA Langley Unitary Plan Wind Tunnel.” A 1963 Martin report describing a test of the Titan IIIC/Dyna Soar configuration.
3: Official XB-70 General Arrangement Diagram
4: CAD diagram: a 1974 Lockheed concept for a subscale Space Shuttle Orbiter Mach 9 flight test model, to be dragged behind a YF-12C and booster by an “Avanti” rocket (modification of the D-21B’s booster) with an internal SRAM motor in the orbiter.

An artists impression of the “DC-3” Space Shuttle concept. This was a two-stage system using two manned flyback vehicles with straight wings and turbofan engines. It was intended to be a low-cost approach, disdaining high performance for simple design and – theoretically – easy maintenance. The orbiter here had two jet engines in the nose for landing and flyback range extension; aerodynamic fairing would cover the inlets until after re-entry, jettisoned once the vehicles had decelerated to below Mach 1. The straight wings would be easy to build and low in weight compared to large delta wings, but of course they wouldn’t provide the same amount of lift. Consequently, the orbiter would less “glide” during the initial re-entry than “belly flop.”
I’ve uploaded the full-rez version of that to the APR Dropbox, into the 2020-10 APR Extras folder. This is available to any APR Patron or Subscriber at the $4 level and above.
Recently sold on eBay (but not to me, I got beat out) was a piece of concept art of the “Colossal Guppy,” a proposal by Aero Spacelines to convert a B-52 into a Saturn S-II carrier. All of the artwork I’ve seen before has shown a 12-engine design; this eBay art shows only the original 8 engines that were fitted to the B-52. I would assume that this is an earlier iteration of the concept, but can’t say for certain.
Now here’s an odd thing…
Part of the collection of images from the Cradle of Aviation Museum, Garden City, NY, this depicts a Republic Aviation concept circa early 1960’s for putting a scramjet vehicle atop a Titan II first stage. Presumably this is meant to be… I dunno, a space launcher? No wings are in evidence, so cruise flight and a landing seem unlikely. But it would seem a hell of a thing to throw away, so *presumably* it was meant to be recovered somehow. Perhaps it shed the entire payload-containing nosecone and came back using the blunt forward dome of the propellant tank as a heat shield, followed by a splashdown. Dunno.
Also in the collection is the “AX-92 detailed drawing.” Clearly this is an entirely serious proposal, and not at all an example of an artist screwing around for giggles.
One of the main purposes of the Monthly Historical Documents Program/APR Patreon is to get rare aerospace items from eBay. These items are then made available to subscribers/patrons via monthly votes and catalogs.
Below are some of the items I’ve recently paid for (though not as yet received). If you are interested in getting high-rez scans and/or helping me save these sort of things for future generations (as well as keeping my cats in food and litter), please consider signing up for the Monthly Historical Documents Program or the APR Patreon.
