Someone has been trying to sell a lithograph on ebay for a *long* time without apparent success… probably because they want $650 for it. Move that decimal place to the left, and I would stand a decent chance of buying it… but for $650, it has to be the *original* art. No way for a *small* lithograph.

The listing is:

1960s GENERAL DYNAMICS “Small ICBM” Concept Art Lithograph Print 8.5×11 RARE

It’s not from the 1960’s, but the 1980’s. It depicts a General Dynamics “Midgetman” Small ICBM concept launching from a mobile launcher; a concept the Soviets (and Chinese, and Norks) ran with, but the US never really got behind. The launcher seems very likely to be the artists fantasy; these vehicles were designed to withstand a reasonably nearby nuclear strike, and one of the ways they did that was by not having a huge single piece canopy.

North American Model 704

Shortly after WWII the US Air Force funded studies on long range missiles, wit the intent of incorporating what had been learned from the Germans. One design, the 1947-vintage North American Aviation model 704, was derived (through numerous steps) from the German A-4 (V-2), but made longer range by way of adding wings and two ramjet engines. This would eventually evolve into the “Navaho” intercontinental cruise missile; an impressive but ultimately doomed system that used a large liquid rocket booster to shove a large Mach 3+ ramjet aircraft into the sky. In the end, ICBM were easier and cheaper.

The full rez scan of the diagram has been made available to APR Patrons/Subscribers at above the $10 level.

A piece of artwork attributed to the DoD (1984 or before) depicting a large structure being built in space. Since it’s DoD, it is most likely a surveillance or mapping radar system of some kind, or an electronic listening system. Since it doesn’t seem to have either large PV arrays or a nuclear reactor – at least not yet at this stage in construction – I’d lean towards it being a listening system. Of course, a great deal more stuff may have been added to it after this… assuming it’s an actual design and not pure art.

Before the RAH-66 Comanche, there was the LHX (Light Helicopter Experimental) program of the 1980’s. Initially the need was broadly defined, and companies such as Bell interpreted it to include the possibility of single-seat combat tiltrotors. The Bell Advanced Tiltrotor (BAT) was one such design. It was design for battlefield surveillance, ground attack/anti-tank… and for blowing Soviet Hinds out of the sky. Whether a tiltrotor could be made that could be safely handled by a single pilot while doing all that craziness is far from certain, especially with 80’s-tech, but the design was certainly appealing. Unlike attack helicopters and F-18’s, the BAT could escort the V-22 on its missions.

Clearly the overall configuration has a great deal of similarity to the XV-15 and the V-22.

Variable geometry SST

A 1970’s Boeing concept for a variable geometry supersonic transport. Once the Boeing 2707 was cancelled in the wake of the oil crisis, any further work on supersonic transports focused heavily on “how do we make this more fuel efficient.” One approach was to go back to variable geometry, which had been dropped from the SST program when the 2707-200 was replaced with the 2707-300. The swing-wing of the -200 worked wonders for the low speed performance of the aircraft, but played hell with cost and weight, enough so that the -300 had a fixed modified delta wing.

The solution shown below linked a few technologies. One concept that showed promise was the “oblique wing,” as tested on the AD-1. A single-piece stricture connected to the fuselage at a single pivot point; much lighter and simpler than a traditional two-pivot swing-wing. With sufficiently rigid structures – think “carbon fiber” – the forward-swept portion could remain reasonably flat even at high speed. But this concept went one step further and linked *two* fuselages to not only a single oblique wing, but also an oblique tail. This would put the “aft” fuselage behind the shock wave shed off the nose of the “forward” fuselage, greatly reducing drag. You’d have the capacity of two SSTs for the operating cost of little more than one. Neat idea… very complex. I’m not sure if it made it much further than preliminary wind tunnel testing.

McDonnell Model 176 Lifting Body Crowdfund Success

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).

If you would like to help fund the acquisition and preservation of such things, please consider signing on either for the APR Patreon or the APR Monthly Historical Documents Program.
