Artwork of the Boeing Integrated Manned Interplanetary Spacecraft, circa 1968. This is the best known of the numerous manned Mars spacecraft designed over the last half century, and is often directly associated with Werner von Braun as he would go on to try to get congress and NASA to forge ahead with the program. Obviously he was not successful. Aspects of this spacecraft design were illustrated in great detail in US Spacecraft Projects #03 and USSP #04

I’ve seen this piece of art many times over the years, always in pretty poor resolution; I finally found a good-rez version on eBay a while back. I’ve made the full-rez scan available to above-$10-subscribers to the APR Monthly Historical Documents Program/Patreon. Clearly the original painting must have been done in color, but I do not think I’ve ever seen this image reproduced in color. I suspect that about ten seconds after I keel over someone will put on eBay a 24X26 full-color pristine lithograph with a buy-it-now price of five bucks. So keep an eye out for that: you see it, I’m like as not deadern’ disco.

If this sort of thing is of interest, consider subscribing. Even a buck a month will help out; but the more you subscribe for, the more you get… and the more you help me get from eBay and save for the ages.

Plexiglas Space Shuttle

A video where some guys get into the archives of the US Space & Rocket Center in Huntsville, Alabama. On display is a sizable (looks like about 1/50 scale) Space Shuttle, ET and Boosters made from plexiglas. It is a thing of beauty, surely a chore and a half for the model shop back in the day. This is *not* the final Shuttle design; some differences are obvious such as the split cargo bay doors and, while unmentioned in the video, the existence of extended OMS pod fairings, reaching out onto the aft of the cargo bay doors.

Last time I visited the USS&RC in something like 2005 they had a much bigger plexiglas STS model on public display, something like 1/10 scale, along with a gigantic plexiglas Saturn V. Such things are fantastic artifacts, and if you are working on a complex engineering project like this a see-through plexiglass large scale model is terribly helpful. I suspect that such things are only rarely made these days, as computer graphics are a lot easier, cheaper and more readily updatable. But nothing beats a Real Thing. And at least so far, 3D printing is not up to the job of stamping out large-scale transparent models like this. But someday…

Sea Dragon vs Saturn V

A scale comparison between the Saturn V and Sea Dragon CD models I’m working on for a 1/7o0 scale kit for Fantastic Plastic. The Sea Dragon would have had about four times the payload of the Saturn V, despite being *gigantic* compared to the Saturn V. This was due to the fact that the Sea Dragon was, by design, a *low* performance vehicle, using simple pressure feed. the result was that everything was necessarily gigantic… giant engines, tanks, wall thicknesses, plumbing lines, etc. While the main propellant feed lines for most rockets are measured in inches, up to a foot or two, in diameter, the LOX and RP-1 lines at the base of the Sea Dragon were about ten *feet* in diameter.

X-60A

The Air Force Research Lab has released a half-heartedly CGI animated video showing the X-60A hypersonic research vehicle designed by Generation Orbit. This is a small unmanned missile to be carried to release altitude underneath a modified Gulfstream III corporate jet, where it would fire its own throttleable liquid rocket engine and climb to cruise altitude (~130,000 ft). The vehicle is fitted with an unconventional set of wings and control surfaces; it’s not immediately clear just what it’s supposed to do other than go fast. One would imagine that high-Mach airbreathing propulsion systems would be of interest to the USAF these days, and scramjet technology is mentioned as part of the proposed payload, but how such equipment would be integrated into the vehicle is unclear.

Orbital railgun

An illustration from 1984 showing the main features of an orbital railgun for the Strategic Defense Initiative program. While the design looks reasonable enough, almost certainly this is either missing a whole lot of important details or has changed them into unrecognizability. Scale is impossible to determine, but a practical space-based railgun capable of generating the projectile velocities needed (typically 10 km/sec) would have been an impressive structure indeed.

Hughes Hot Cycle Heavylifter

A magazine ad from 1967 showing a concept for a “Hot Cycle” helicopter. The “hot cycle” was a way to spin the rotors without imparting a massive torque to the fuselage as usually happens with helicopters, requiring a tail rotor to counter. here, instead of mechanically linking the engine to the rotor via drive shafts and gears, the engine exhaust was ducted up through the central rotor shaft, then out to the tips of the rotors, and then ejected through thrust-generating nozzles. This would impart only a trivial amount of torque to the fuselage, largely from friction with the shaft bearings. it was a great idea, but there were some issues with leakage around the bearings as well as being impressively loud and fuel-hungry.

Note that while the “hot cycle” eliminated the great majority of the need for an anti-torque tail rotor, this and similar designs still had one. This tail rotor would be used to swing the tail back and forth, yawing the aircraft at low speed.. This woudl require that the rotor be able to provide thrust in either direction on demand.

Another early look at US Spacecraft Projects #6, this time showing one of the more unusual space vehicles ever seriously contemplated… a single stage to orbit space station. This one would seem to be especially vulnerable to thrust imbalance, but at least it had enough engines (11,520) so that if one went out, the lack of thrust wouldn’t be *too* hard to counter.

“Big Stick” art

The San Diego Air and Space Museums Flickr account recently added this illustration, showing a Convair “Big Stick” being launched off the back of mobile transporter. “Big Stick” was a Convair concept for a nuclear ramjet powered cruise missile of nearly unlimited range, a less-known competing design against Voughts Pluto vehicle.

A higher rez (though, sadly, not a whole lot higher) version is available HERE.

If you are interested in Big Stick and Project Pluto, I recommend Aerospace Projects Review issue V2N1, which covers both in detail.
