Stratolaunch LLC announces it has successfully completed a separation release test of the Talon-A separation test vehicle, TA-0. The flight was the eleventh for the company’s launch platform Roc and the second time the team has conducted flight operations in Vandenberg Space Force Base’s Western Range off California’s central coast.
In 1983 “Science Digest” ran an article that 13-year-old me lost his tiny little mind over. Illustrated by Rick Sternbach, designer of, among other Star Trek vehicles and artifacts, the USS Voyager, it described a series of possible means of interstellar travel. While the physics and engineering of some of them have proven dodgy in the years since (the Bussard ramjet has serious problems with the proposed magnetic fiend, the Enzmann starship has turned out to not be as well thought out as many had assumed, etc.), it remains a tantalizing glimpse of what might be. The article has been scanned in full color and made available to APR Patrons/subscribers at the above-$10 level.

My preference with the cyanotype diagrams is to not tinker with the actual image other than the needs of cleaning them up. However, in a few cases the diagrams are such that they make inconvenient fits, or could be made into convenient sizes… or need additional stuff added to them to flesh them out. One such case is the Aerojet Sea Dragon launch vehicle. The diagrams I have come from reports, rather than blueprints; this stripped them of the usual data blocks, and left them with just the diagrams. Putting the external profile next to the internal profile gives an aspect ratio that is *almost* perfect to fit within an off-the-shelf 11/75X36 inch frame. I need to do a bit more to add a bit of something to the blank spaces.
The question here is whether the cyanotype-buying public would rather have this formatted to display horizontally as shown here, or vertically?
As an aside, I just noticed that the original GIF that I’d put together (for APR issue V4N6) was dated as March 9, 2003, just over twenty years ago. I posted the full-rez diagram on my website many, many years ago; since then it has filtered out into the wider world, such as HERE, HERE and HERE.
I will be posting some more cyanotype blueprints to ebay in the coming days. These were made from old transparencies I’d had made prior to the move from Utah. But I also hope to have some “brand new” cyanotypes in the near-ish future. The transparent film remains astonishingly elusive; two separate companies are trying to obtain it… and have been for a few months now. Every other print shop in the area has flat refused to try. A print shop a few hundred miles away made a few transparencies for me a few months back; I just sent them files to have a few more made. With luck they’ll come through. I have a *bunch* more I’d like to have done. Here are what I recently sent off:
Martin XB-51. The original print was 1/40 scale; this blueprint will be 1/72 scale.
The Avro “Arrow” structural layout.
Two sheets from NASA illustrating the Saturn V. One sheet is very likely more interesting than the other, so what I might end up doing is ebaying the two sheets and cataloging just the one.
The US-1205 and UA-1207 solid rocket motors for the Titan IIIC and IIIM, respectively. I have the originals of these framed and hanging on my wall; conveniently, they fit in off-the-shelf 11.75X36 panorama frames that you can get at Hobby Lobby and the like. I will probably tinker with some of the other blueprints that are *close* to this size to massage them to fit into that frame. Because as awesome as the prints are on their own, they’re spectacular framed.
I have also sent a revised version of my SR-71 CAD diagrams to be re-printed. The first print’s lines came in too light/fine. Live and learn…
A program progress film from 1959 describing the US Army’s “Saturn” rocket. This would soon be transferred to NASA, eventually becoming the Saturn I (then Ib). The basic layout of the first stage would remain, but the upper stages would change utterly; as shown here, they are derivatives of the Titan ICBM. Note that the first stage is shown being recovered. This feature lasted a surprising length of time, with components being built into the early NASA Saturns. The idea was that the stages would be parachute recovered with solid rocket motors firing at the last second to cushion splashdown. The motor firing would be set off by a trigger that would be released from the booster to dangle some distance below. As soon as the trigger hit the water, it would signal the motors to fire. The stage would splash down soft enough to be recovered, but it was assumed it’d be damaged beyond refurbishment. The idea was to examine the stage to see how it did, and introduce incremental improvements until *eventually* it was able to be recovered intact enough for cost effective refurbishment and reuse.
I’m selling the blueprints I’ve recently made. I can sign ’em if the buyer wants, front or back…
A 1950’s film describing the “Lobber” rocket from Convair. This was a small battlefield cargo delivery system… rations, medical supplies, ammo, that sort of thing. Kind of a neat idea, but obviously it didn’t go into service. The ability to launch 50 pounds of stuff eight miles just wasn’t that spectacular when cargo planes could para-drop tons of stuff hundreds of miles away, when choppers could zip in and out in the time it would take to pack stuff into the rocket. Today i imagine drones would take on the task… not as fast, but less harsh on the cargo and much more precise.
Note that it is also described as a system capable of delivering *nukes.* Well, any rocket that you can swap out the payload could be a nuclear delivery system if it’s got the capability. Fifty pounds just barely covers it. It would be safer for the launch crew than a Davy Crockett with a range of only a couple miles, but 8 miles is still pretty close. The W54 warhead weighed right about 50 pounds and could yield up to about one kiloton. Eight miles would be a safe distance… so long as the fallout didn’t rain down on your head.
The “Enzmann Starship” is named after Robert Enzmann, who “designed” it decades ago. Just exactly *when* has been an issue of some confusion in recent years.
It first came to light in the late 60’s or early 70’s, with claims that he thought it up around 1964 or so. The design is unique: a giant spherical ball of frozen deuterium fuel at the front, followed by a cylindrical ship, ending with a series of Orion-style nuclear pulse engines. It was an *ok* concept for a practical starship, though relatively recent analysis presented in the Journal of the British Interplanetary Society argued that it was not nearly as good as imagined. It became something of a sensation in the 70’s after appearing on the cover of “Analog” in 1973.
Nothing has ever been produced, so far as I’m aware, backing up the concept with any sort of detailed design of analysis until that JBIS paper. No reports, proposals, pages of math, from Enzmann seem to be available… just text descriptions of a few sentences and some art. And that’s fine. But in recent years the claims have become more and more expansive. Enzmann, near the end of his life, claimed that the design for a nuclear-pulse vehicle dated not from the time of the Orion program, but back to the *40’s*.
I spoke to Enzmann on the phone a few times over the years. He was enthusiastic, verbose… and baffling. He made lots and lots of claims about having worked on this or that amazing program, but when asked for verifiable details… it was classified. Those who have picked up his mantle and are trying to carry his torch seem to be following in his footsteps there, continuing his claims without much apparent criticism. I’ve recently engaged their twitter contact to get some sort of verification of his claims… but we have now reached the point where not only am I convinced that no such evidence will be produced, I feel no reason to assume anything remarkable is true at all. Behold:
He published nothing on his Starship before NYAS conference #1 other than his own words. ANP aircraft were built in the 50's, and buried deep under a NM mountain, according to Enzmann, who was there. He is the reference.

Claiming that nuclear powered aircraft were actually built in the fifties and then buried in a mountain? Yeah… no. I’m out.
