Putting together the 3D CAD model of a General Electric has been complex but straightforward… but hammering the 2D diagrams made from it into shape has proven a bit challenging. Most of the 2D work is done in an ancient version of AutoCAD, but there was something about the diagram (created in Rhino 3D) that caused ACAD to either lock up or crash. So finalizing the diagram has been done in Rhino, which means the diagrams will look a little different.
A follow-up to the earlier photo set of Burans at Baikonur left to rot: a full -scale mockup of the Energia-M launcher. The Energia-M was a planned smaller two-booster version of the four-booster Energia used to launch the Buran orbiter… and, like the Buran orbiters, it has been left in place and is slowly rusting away.
I have added three hi-rez scans to the APR Patreon “Extras” Dropbox folder for the month of 2015-07. If you are interested in these, they are available to all $4 and up patrons at the APR Patreon.
Bell artwork from the late 70’s or ’80’s depicting the D316 tiltrotor, a proposed operational derivative of their XV-15 research tiltrotor.
Convair 58-9 SST, derived from the B-58 bomber (see HERE for a well illustrated article on this and other B-58 SSTs):
Early artwork for a VTOL fighter concept from Ryan; this would eventually become the X-13:
Avast amount of work was put into space-based weaponry during the SDI days, but the bulk of that work has remained tucked behind security classification. Artwork was released publicly from time to time, but with rare exceptions that artwork was pretty clearly either not based on actual engineering design work, or was stripped of important features.
In all my digging I’ve found a grand total of *one* illustration of a space based railgun that I’m fairly confident represents a serious design effort. Sadly dimensions were lacking… but the design included a nuclear reactor and radiator system was was very likely an SP-100. While the SP-100 system itself appears to have been in constant flux, scaling the whole assembly from the size of the radiators leads to something I’d estimate accurate in scale within +/- 15%.
For a future USSP release, I decided to include this railgun as I included the Zenith Star laser in issue #1. The easiest way to make good 2D diagrams for something this complex is to make a 3D CAD model based on the sketch, including the SP-100. I didn’t know how big the railgun was supposed to be; I didn’t try to scale it until I had it largely put together with the SP-100 in place. And boy, is it *not* small:
The shuttle is of course to scale.
Several details lead me to think that this General Electric concept is on the up-and-up:
1) It includes the SP-100. This was often (not always) left off of images for public consumption.
2) It includes *very* large planar array radar for targeting warheads thousands of kilometers away, something I’ve *never* seen elsewhere, but which is pretty obviously important.
3) It has a fairly substantial, though unclear, storage for LOX and LH2 hidden behind a thermal shield/radiator. Note: the nuclear reactor was to keep the system running for years while awaiting The Day, and for running systems like computers and radar and such. But the power needed for the railgun was vastly more than the SP-100 could provide; the LOX/LH2 would run a turbogenerator to crank out the megawatts needed to make the gun go bang.
4) It doesn’t look “sci-fi cool” so much as it looks like a “great big thing built in space.”
Launching this monster would have been a hell of a chore. Presumably it would go up in pieces atop an ALS booster, and there assembled by a human crew launched via shuttle.

While this is broadly much like the STS as actually built, there are a lot of important differences. The spine down the top of the cargo bay… that was to give room for the cargo manipulator arm without putting it actually in the cylindrical bay, taking up valuable cargo space. The booster rockets have teardrop ports on the cylindrical sections just aft of the nosecones… these are the thrust termination ports that, in the event of an abort, would blow out through the forward dome of the rocket motors. This would not only slash the chamber pressure in the motors, it would provide an escape route for the hot gas to go forward, cancelling the thrust from the aft nozzle. The ET is of a slightly simpler geometry; the small cylinder on the nosecone contained the de-orbit solid rocket motor (because the ET would either go into orbit with the Shuttle, or so close to orbit that the splashdown location would be somewhat randomized).
I haven’t had an opportunity to really dig into this, but Boeing just patented a jet engine powered not by hydrocarbon fuel combustion but by small nuclear explosions. Basically an Orion (via laser-driven inertial confinement compression of tiny fusion fuel pellets) in a jet, stuck on a passenger plane.

Sigh. Every single time I think I’ve got a handle on “this is everything in the world of NPP, I can finally finish the book,” they suck me back in

Anybody know where I could get a copy of the CAD diagram (or similar) of the Space Launch System shown in the background of this image?
For APR Patrons, here’s what you now have available:
Documents: 2 General Electric reports on nuclear turbojets, *packed* with diagrams
Document: Mercury/Redstone booster recovery
Large diagram: 2 this time… “Long Tank Delta” space launch rocket and “Honest John” battlefield nuclear missile
CAD diagram: Convair “FISH,” 1958 configuration

A blog reader provided this scan. It comes from the archive of the Imperial War Museum, and was all alone in its folder… what you see is all there is. It appears to show a rocket powered “rammer,” with a massive armored nose for slamming into enemy bombers. The pilot is provided with an easy-bailout ramp, presumably to be used after aiming his plane at a target but before impact (I would *not* want to be in at thing when the actual ramming occurs). Presumably dates to WWII. The style of drawing looks like a patent drawing. My guess is that it was a patent submitted by Just Some Schmoe during the war, and is not a serious concept by a reputable design firm, but I don’t know for sure. If anyone has firm data, please advise.
