Three magazine advertisements from 1960, depicting the East German Type 152 jetliner (which would have been a *fantastic* jetliner in the late 1940’s), the Convair F-106 and the Fiat G91 T jet trainer.

B-1B Ad

The ad below was published in magazines in 1982, showing a cutaway illustration of the then-fancy new B-1B bomber, recently rescued by the Reagan Administration. The background is here depicted as a rather dull gray, but the physical ad has a shiny metallic coating, which must have cost a small fortune at the time.

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.

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).

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.

“SIPS”

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.
