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.

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.

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.

I’ve been running the Aerospace Projects Review Patreon project for a bit over two years now. Every month, Patrons get rewarded with sets of aerospace history stuff… currently, one large-format diagram or piece of artwork, three documents and, depending on level of patronage, an all-new CAD diagram of an aerospace subject of interest. More than two dozen such packages have been put together so far and distributed. Given that you can get in on this for as little as $1.50 a month (for 125-dpi scans… $4/month for full-rez 300 dpi scans) and you get at least four items, that’s a pretty good bargain compared to the individual aerospace drawings and documents.

Patrons who signed up after the process got underway can now get “back issues” of the previously released rewards packages. A catalog of more than the first years worth has just been posted; each month will see an updated catalog posted for Patrons to order from. So if you are interested, check out the APR Patreon page to see how to sign up; if you are already a patron, check out the catalog here.

Produced by Bell Aerospace around 1960 as a promotional item was this “ticket” for a flight from New York City to Melbourne, Australia. The aircraft shown was a two-stage hypersonic passenger transport; the first stage was essentially a supersonic transport equipped with turboramjet engines; it carried on its back a rocket powered passenger spaceplane. At the time it was pushed by the likes of Walter Dornberger, who had previously publicized a two-stage all-rocket powered hypersonic transport. There was some link between this design and the Dyna Soar program, but it is unclear just how involved the engineering was on the HST. Artwork was produced and a good display model, but it’s hard to tell if it went any further than that.

I have uploaded high-rez scans (600 dpi) to the 2016-09 APR Extras folder on Dropbox. This is accessible to all APR Patreon patrons at the $4 level and above.

Every now and then ebay provides some interesting items that are just plain too expensive. One such is a Boeing presentation on using the 747 to carry and air-launch MX ICBMs. The original Buy It Now price was over two grand; consequently, the document remained on ebay for something like a year. However, I negotiated down to $250. Still too expensive, but crowdfunding makes it reasonably affordable.

I currently have about 9 people interested in splitting the cost. Nine plus me means the cost is $25 per person… suddenly not quite so horrible. If more people come on board, the price will fall even more. Twenty people total drops it to $12.50 each. Thirty drops it to $8.33, and so on. Each contributor gets a complete high-rez scan of the document.

If you are interested in getting in on this, it’s open to APR Patreon patrons at all levels. Check out the APR Patreon for this and other rewards. The most recent posting at the APR Patreon has a place to comment and express your interest in getting a copy of this document.

The opportunity will be open until the document arrives in the mail, which should be a few days.

A heavily illustrated USAF brochure on turbine engine technology included, among a vast number of little photos of engines and aircraft, a few illustrations that might be of interest.

Several futuristic concepts here, several old ones. Of particular interest is the “Supersonic Multirole Fighter,” which looks like a cross between the old Lockheed Hopeless Diamond concept and the Northrop XST design… tailless with an inlet on top, with features reminiscent of the F-117, but blended rather than faceted.

Of these “Emerging Concept Needs,” several are distinctly old. The middle row of three designs are all 20+ year-old concepts.

An early Boeing concept for the 767. This was designed for cruise at high subsonic speeds; the unusual “wasp-waisted” fuselage was to give the configuration the area ruling needed for low-drag transonic flight. This concept, studied by Boeing, General Dynamics, Lockheed, NASA, Bell and others, arose after the spike in oil prices in the early 1970’s and the demise of the SST program. The goal was to create a jetliner that could fly just as fast as possible while still being economical with fuel. But production costs of the curvy fuselage and wings doomed the effort.

This scan is from a print currently on ebay.
