Currently for sale on EBay is a presumably-vintage model of a Lockheed C-141 in civilian livery. While the C-141 wound up solely a military transport, it would not be surprising that Lockheed would try to sell it on the civilian market. The model doesn’t depict passenger windows, so this was, presumably, still a cargo carrier.

The Aerospace Projects Review Patreon rewards for January will include a reasonably massive Douglas report on the Saturn V-launched pre-Skylab “Early Orbital Space Station” and a scan of a reasonably gigantic diagram of the Boeing 2707-300 SST. These will be released before the end of January and will be available to all then-current Patrons. So if these items interest you, and/or if you are interested in helping the effort to find and preserve this sort of aerospace history, be sure to check out the APR Patreon.

Currently on EBay is a vintage piece of artwork that depicts – apparently – a robotic Mars lander probe. it looks a lot like a cross between Surveyor and Viking; it *might* be an advanced Voyager design (from when Voyager was a Saturn V-launched Mars mission, before it was a Titan III-launched outer solar system mission) from the late 1960’s.

A meeting of giants at Edwards Air Force Base in the late 1960’s. It’s interesting to compare the size of the “fighter” with the “bomber…” the bomber, as anyone who has ever stood underneath the sole example in Dayton, is Really Big, but the YF-12 is just not that much smaller. Sustained Mach 3 flight is not for the faint hearted… or the small-engined or those with dainty fuel tanks.

Currently nearing its end is an auction for a vintage NASA 8X10 glossy, an artists impression of the Lunar Module separating from the Apollo Command and Service Module. It’s a bit interesting in that it shows an early version of the LEM “bug,” with a number of important differences from the as-built LEM. Note the extended “snout” on the Apollo Command Module for docking with the LEM.

What makes this auction “inexplicable?” At this point, with ten hours to go, there are 14 bids so far with a top price of $115. I’ve seen larger format lithographs go that high, but I’ve never seen a  single 8X10 glossy get anywhere near that expensive before, with that many bids.

The same seller has a number of other NASA glossies, most pretty standard. But there’s another early LEM artist concept, currently going for $15. The LEM shown is even earlier than the one above, so I’m a little stumped why it’s currently selling for a small fraction of the price.

This display model was sold on EBay some months back:

twin-747-sca-9 twin-747-sca-8 twin-747-sca-7 twin-747-sca-6 twin-747-sca-5 twin-747-sca-4 twin-747-sca-3 twin-747-sca-2 twin-747-sca-1

Without a display stand it’s difficult to determine exactly who made this, but all indications are that it was an “official” model, made by Boeing, Lockheed or NASA. The design was given some small amount of study around 1973, though the available documentation on it is lean.

Lockheed studied the same idea with the C-5 Galaxy. Of course the C-5 would have been easier to modify since it already had shoulder-mounted wings.

I’d posted this YouTube video a few years ago, but I’ve found that not only was the video yanked, the whole account associated with it was nuked. Hmmmph.

A film about NERVA (Nuclear Energy for Rocket Vehicle Applications), 1968.

Provides a basic description of nuclear rockets, plus some art, animation and diagrams of nuclear propelled space vehicles along with footage of test firings.

Recently sold on EBay was a sizable  (something like 4′ long) wind tunnel model of the Curtiss Wright Model 90 AAFSS submission. This was a derivative of their X-19… more or less a quad-tilt-rotor. The Model 90 would have been fairly highly armed, designed to fulfill the same role that the winning AAFSS design – the Lockheed AH-56 Cheyenne – was designed for: transporting troops and tearing up ground targets. The US has not had an operational vehicle like this; the Soviet “Hind” helicopter is the closest, though substantially slower, analog.

The Model 90 wind tunnel model was formerly on display at an aviation museum in Teterboro, New Jersey. No idea where it ended up, but hopefully it found a good home. I made a half-assed effort to crowdfund this one, but I think the lack of a good way to split the spoils among the funders doomed the concept. How *do* you reward funders for a purchase like this? Best idea was to have the thing 3D scanned, and distribute the scan among the funders, but unlike a scan of a drawing or a document, that’s not going to be readily useful for most people.

What I’d hoped to do was to disassemble the model, male fiberglass molds of the components, reassemble and restore it to like-new-ish condition then send it on to an appropriate and willing museum, possibly Ft. Rucker (since they’re all about Army aviation and have themselves an AH-56). Then make a few fiberglass copies from the molds, converting the “wind tunnel models” into detailed display models. Alas.

A recently sold item on EBay was this piece of artwork depicting a Boeing concept for an airliner powered by two propfans. These engines, popular items of study in the late 70s and into the 80s, were somewhere between turbofans and turboprops, with contra-rotating unducted fans using blades of complex design and contours. The advantage was, of course, fuel efficiency; the shape of the blades meant that they could spin with tip speeds closer to the speed of sound compared to turboprop blades, and could push the plane faster than normally practical for a turboprop.

Given the NASA logo on the tail, this piece of art undoubtedly depicts a proposal for an unducted fan test vehicle. The gray areas on the wing upper surfaces may indicate laminar flow control via suction, as with the Northrop X-21; this would all conspire to make this a very fuel efficient, if also very complex, jetliner.

From the NASA-Marshall Space Flight Center, December, 1961: An illustration of the forthcoming Saturn C-5 S-IC stage. This appears to be *mostly* as the S-IC would be built, but there are some detectable differences. Missing are the four small (and apparently superfluous) stabilizing fins that appeared on the outboard engine fairings. And located at the front are the eight retro rockets that would end up inside the aforementioned  engine fairings.
