Possibilities of New Business Growth: Space Command Post

Mar 182020

In 1985, Rockwell International considered the possibility that there might be profit in a space station with a singular purpose… to serve as a command post in the event of a nuclear war. Its position would let it confirm Soviet ICBM launches and direct space based weapons in their response. Presumably this means that there would need to be several such orbital command posts. The brief description suggests that the command post would be in “high orbit,” perhaps geosynchronous; to have global coverage, at least two and preferably three or more such posts would be needed. The lower the orbit, the more would be needed to see the whole planet.

A 1960 Lockheed concept for a jet-powered “Super Hercules.” This would transform into the C-141 Starlifter.

Given the craziness going on, I decided that what the world clearly needs is something consistent. Like, say, me posting one piece of aerospace diagram or art every day for a month or so. So I’m going to do that. But in order to keep people from getting too complacent, I’m posting some of them on this blog, some on the other blog. Why? Because why not, that’s why. I’m slapping the posts together now and scheduling them to show up one at a time, one a day. Given the pandemic… who knows, this little project might well outlive *me.*

So, check back in (on this blog or the other) on a daily basis. Might be something interesting.

D-558-I Skystreak

Cutaway artwork of the Douglas D-558-I Skystreak, a transonic research plane designed and built in the mid 1940’s for the US Navy. Like the contemporary Bell X-1 rocket plane, it had straight wings; but unlike the X-1, it had a turbojet engine and could take off under its own power. It could only get supersonic in a dive. Douglas followed the D-558-I with the D-558-II Skyrocket, a very different and much more advanced aircraft that could fly much faster.

The full-rez scan of this cutaway has been made available to all $4 and up APR Patreons and Monthly Historical Document Program subscribers. It has been uploaded to the 2020-03 APR Extras folder on Dropbox for Patreons and subscribers.

Sea Dragon Operations

Sea Dragon was, as is doubtless news to few around here, an early 1960’s idea at Aerojet for an extremely large, very simply two-stage pressure-fed space booster. It was meant to be as cheap to build and operate as possible with 1960’s tech, relying on scale to make it all work. Would it have worked? Maybe. Physics supports it. Would it have been cheap to operate? Hard to tell. “Simple as possible” does not equate to “simple,” and anything the size of Sea Dragon, especially screaming out of the sky to smack into the ocean while blisteringly hot… well, there are always risks.

In 1963 the idea of a pinpoint vertical landing a la the Falcon 9 would have been ridiculous, so splashdown was really the only way to go for a booster designed for simplicity. But as NASA and Thiokol found with dropping Shuttle boosters into the drink, recovery and refurbishment after salt water immersion can be a bit of a headache. The way to make a Sea Dragon truly economically competitive would be, as with Falcon 9, flight after flight after flight, often enough that it ceases to be an Amazing News Story and becomes, like the Falcon 9, seemingly dull and monotonous. But given the million-pound payload of the Sea Dragon it’s difficult to envision a space program following on the footsteps of Apollo that would have required a Sea Dragon every few weeks. It would certainly have been *nice* to have had such a program (and if the current pandemic takes down western civ it will turn out that the lack of such a program was criminally negligent) but the existence of a timeline with such a program seems a little difficult to envision.

The article, written by sea Dragon advocate Robert Truax, that the above illustration came from has been scanned and made available to above-$10 APR subscribers and Patrons.

Possibilities of New Business Growth: Space Nuclear Power Systems

Mar 082020

In 1985 Rockwell International thought that there might be a business case for space based nuclear power systems. The customer base for nuclear reactors in space seemed to be restricted to military satellites (warning and recon mostly) and deep-space exploration systems. Advantages over solar power include resistance to the degradation of PV arrays due to passing through the ionizing Van Allen radiation belts and no need to track the sun. Costs, however, were high… high enough that in the end nothing came of it.

Possibilities of New Business Growth: Solar Power Satellites

Mar 062020

By 1985, the “Solar Power Satellite” program of the late 1970s was effectively dead. SPS rose to prominence atop the rising oil prices due to OPEC oil embargoes and the like, but in the early 80’s the global price of oil collapsed and potentially competitive systems such as SPS suddenly were no longer remotely competitive. Still, Rockwell International hoped that they could leverage their considerable experience with SPS to generate a [profitable business. But it was not to be.

Coulda Shoulda EMPIRE

This video was posted on YouTube some six-ish years ago, but remains worthy of viewing and discussion. It’s a General Dynamics film to NASA from late 1962/early 1963 discussing the study of Early Manned Interplanetary Missions (EMPIRE), NAS8-5026. It describes the future as it should have been… and as how Krafft Ehricke, the presenter of the film and one of the driving forces behind the program, saw it:

1: Manned landing on the moon by the end of the 60’s.

2: Initial manned flights to (flybys and orbits) Venus and Mars in the early 70s

3: Entire solar system explored robotically by the end of the 1980’s

4: Manned mission to Pluto by 1995

Ehricke’s view of the future of space flight from the standpoint of the mid-1960’s was previously shown HERE.

The original film included a number of bits of concept art of both manned and unmanned spacecraft. Sadly no Orion vehicles are on display (it is name-dropped), but the Mars lander/excursion module was of the kind originally proposed for Orion. This was pre-Mariner when the Martian atmosphere was *massively* over-estimated; these landers and their dinky parachutes would, with the real Martian atmosphere, have made impressive craters in the surface.

PDF Review: A Whole Bunch of Enola Gay Photos

If you like the aircraft that applied atomic boot to Imperial Japanese ass – and who doesn’t – then the Smithsonian institution can hook you up. Not only do they have the famed Enola Gay on display, they also have a bunch of photos from 1945 up to more recent restorations available on their website in the form of a couple PDF collections. If you are building a B-29 model or are jsut interested in the B-29 in general or the Enola Gay in particular, this is a heck of a trove.

The first one is 419 pages (313 megabytes), with a lot of photos from what looks like the fifties to the nineties as the Enola Gay was trucked around and variously restored:

https://airandspace.si.edu/webimages/collections/full/A19500100000DOC20.pdf

The second is 318 pages (77 meg) and seems to be detail photos (mostly of pretty much individual components) from a restoration:

https://airandspace.si.edu/webimages/collections/full/A19500100000DOC06.pdf

A number of the photos can be viewed – thought not readily downloaded – here:

Early North American Rockwell Shuttle

The North American Rockwell proposal for the Space Shuttle Orbiter. It is clearly *close* to what actually got built, but there are important differences. The airlock is in the nose and the OMS pods are lower on the sides of the rear fuselage and the rear portion of the cargo bay could be fitted with a pod that includes flip-out turbofan engines for range extension and landing assistance.
