Convair Model 54

Oct 152015

A Convair illustration of the Model 54, a proposed operational version of the NX-2 nuclear powered aircraft. The Model 54 was a missile carrier, but with an internal bomb bay. It was also strictly subsonic, so its survivability over Soviet territory would undoubtedly have been seen as minimal in the supersonic-obsessed 1950’s. By carrying long-range cruise missiles (type unclear), the Model 54 could spend days orbiting outside Soviet controlled airspace and, when war breaks out, dash in at low altitude, unleash its missiles hundreds of missiles from the target (and from the air defenses), and then run home. Of course, the Model 54 was never built.

A full-rez version of this has been made available to $4+ Patrons of the APR Patreon, in the 2015-10 Extras Dropbox folder. If you’re interested in obtaining this, and/or helping the cause of preserving aerospace history, please check out the APR Patreon.

S-N Art

launch vehicles, nukes, rockets, spacecraft No Responses »

Sep 082015

The image quality is admittedly terrible (being a scan of a print of a microfilm), but this might be of interest… a piece of NASA art circa 1963 depicting the Saturn V with an S-N third stage rather than an S-IVb third stage. The S-N was not a fixed design, but varied over the years; here, it was a fairly stubby stage ten meters in diameter, same as the S-IC and S-II stage. The S-N would vary in diameter and length from design to design, but one common element was the use of a single NERVA solid-core nuclear thermal rocket engine. As shown here, the distance from the nuclear rocket to the Apollo capsule up front just isn’t terribly far; consequently, this depicted a design with extraordinary levels of shielding, or depicted an unmanned Apollo (but then, why the abort tower), or it was just artistic license.

10-Meter USAF Orion

Sep 032015

I continue to tinker with the CAD diagrams for “Nuclear Pulse Propulsion,” as well as creating new ones. I decided to see what the diagrams for the 10-Meter design for the USAF would look like in a larger format… in this case, two sheets 40 inches by 10, at 1/96 scale. A fair bit of formatting needed as yet, but on the whole I think they look pretty good.

Anyone interested? I’m thinking a combination of prints (folded into a book or rolled) and cyanotype blueprints on vellum. If this idea is popular (I’m going to take at least this design to print, just for myself), I’d do something similar for the 10-meter NASA vehicle, the 20-meter NASA vehicle and the 86-foot 4,000 “battleship.”

Some large-format scans

Aug 272015

Today I picked up four large format scans from a local print shop. All were scanned in full color at 300 DPI; the B-52 diagram was so large that I had to reduce it in size a bit – from 300 to 250 DPI – to make it work in most of my image processing programs. Still… with an original 110 inches long, scaling down a bit really isn’t much of a loss.

First: a Boeing model shop diagram of a B-52B display model at 1/40 scale. Model shop diagrams are often the best bets for clear, accurate aircraft diagrams.

Second, an old Boeing diagram of the Model 80 trimotor:

Then the USAF “supersonic escape capsule” which sure looks a lot like Fat Man:

And then a Rocketdyne diagram of the Atlas booster rocket engine:

These will likely be offered up to APR Patreon Patrons. If you want in on that, and to help out on the effort to procure these things (trust me, they’re *not* cheap!), please consider signing up for the APR Patreon.

Mini-Art: Lockheed nuclear bomber

Aug 262015

This piece of art has popped up from time to time over the decades (it dates from 1959 or before), showing a schematic view of the basic layout of a nuclear-powered bomber. And while the version below is not particularly clear or high-rez, it has the advantage of being in color.

The truly gigantic-looking bomb is likely not pure artistic license. At the time Lockheed was designing bombs that looked just like this at extraordinary size; they had substantial rocket propulsion capability to let the bomber release the weapon at a considerable standoff distance.

It’s not much, but here’s a color schematic of a nuclear light bulb, taken from a NASA report.

Mini-Art: NASA Orion

nukes, rockets, spacecraft 2 Responses »

Aug 042015

In the 1990’s, into the early 2000’s, NASA gave a few brief looks at Orion-style nuclear pulse propulsion. A few papers on the concept were published, but it does not appear that a great deal of real engineering effort was expended. Given the political impossibility of an Orion in the Clinton years and the diplomatic nightmare than an Orion would have been post 9/11, it’s hardly surprising that the NASA efforts were low level and apparently led to little.

Some artwork was produced. Generally computer generated, and generally reproduced at relatively low resolution, only a little can be gleaned from these pieces. The design shown below uses Transhab technology for the crew compartment and, unlike every known vintage Orion design, it has substantial radiator area. This presumably was for an internal nuclear reactor. If the Transhab used here is the same 8.2 meter diameter as the standard Transhab design, this indicates that the pusher plate is probably smaller than the 10 meter design.
