One of the last, if not the last, chapters in my Nuclear Pulse Propulsion book will be on NPP in popular culture. Mostly, of course, this means nuclear pulse spacecraft in science fiction… short stories, novels, TV, movies. These vehicles will get layout diagrams just like the non-fiction concepts.

With designs that are complex or difficult to really work out – which covers just about all fictional designs – I’ve found that it is a whole lot easier to build the vehicle as a 3D CAD model and then convert that into a 2D diagram. A bonus of doing it this way is that perspective views are also possible. So because why not, here are some of the fictional NPP’s that will appear in the book, along with the current status list for NPP diagrams (green means the diagram is done, yellow means it’s in progress, red means I haven’t started or haven’t gone beyond preliminary scribble). Some of the fictional designs, such as the “Orion Shall Rise” and the Tycho were drawn in 2D right from the get-go. Currently being pieced together is the Archangel Michael. It is a bit different from the usual depiction in a number of ways, most obvious being the straight shock absorbers. I understand the reasoning behind those designs that use angled and pivoting shocks to allow the pusher “dome” to swing with respect to the rest of the ship… but I still don’t agree that that’s a good engineering solution. Once you get the dome swinging, getting it to *stop* is going to be a friggen nightmare, especially if the ship remains under thrust. The dynamics of a spring system like this with that many degrees of freedom would be massively complex, never mind the actual mechanics. Oh well. Anyway, my “Michael” is still far from finished. The interior is only roughly sketched out, armament is currently rough and incomplete and secondary payloads need a lot of work.

In the final book, these fictional designs will get not only orthogonal views, but also to greater or lesser degrees “rationalization.” Some designs I can’t honestly make any real sense of, and thus they’ll get the bare bones. Some I can dream up a fair bit of (essentially fan fiction) explanation for, so they’ll get further detail work.

First up:

Destroyer USS The Sullivans Damaged After Missile Explodes After Launch

An SM-2 Block III missile went BLAMMO just after launch, setting a fire on the ship.

Well, that’s embarrassing. But then the Russian Navy (Navy Day in Sevastopol) is not to be outdone:

Looks like the solid rocket boosters for an SS-N-14 “Silex” torpedo-carrying missile broke away just a little early.

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.

SpaceX Rocket Explosion Likely Caused by Faulty Strut, Elon Musk Says

It seems that a steel strut holding a high pressure helium tank within the liquid oxygen tank broke due to a manufacturing flaw. The helium tank broke loose and overpressurized the LOX tank,causing it to burst.

The Dragon capsule survived to splashdown. however, it wasn’t programmed to pop its chute, so it hit the ocean at high velocity. The next Dragon capsule will have a software update that will allow it to self-recover in the event of another launch vehicle failure.

In the actual history of surface-to-air missile development in the US, we had a number of Nike missiles… Nike-Ajax, Nike-Hercules and in the end, the Nike-Zeus (which was redeveloped into the Spartan). After that, the Nike naming convention came to an end. Cities were no longer ringed with anti-aircraft missiles.

But in the Pax Orionis world, the US remains substantially paranoid about *every* form of threat, so we’d have several new types of land-based city-defending anti-aircraft missiles. But after Nike-Zeus, what might they be called? “Zeus” would seem to be the end of the Greek Deity line. So… what? Nike-Hades? Nike-Kronos? Nike-Achilles? Nike-Typhon? Nike-Hermes, perhaps?

 

Suggestions/discussion appreciated.

Some might question why this mission to Pluto is so interesting to so many. I think I have it figured out: not only is this the first time humanity will have a good look at this entire planetary system… this is also the *last* new world of any magnitude most of us will probably live to see explored up close. Sure, there’s lesser known Eris, which is smaller than Pluto by a few kilometers, but substantially more massive… but last I’ve heard there are no real plans to send a craft there. And it’s something like twice as far from the sun as Pluto, so barring new propulsion systems, it will take twice as long to get there… call it 18 years. Couple that with the time required to actually design, build and launch the probe… New Horizons started design work in 1990, not launching until 2006. So if that process was duplicated starting today, “New Horizons Eris” would launch in 2031 and would flyby Eris in 2049. Assuming it didn’t get cancelled, the booster didn’t fail or the transmitter went wonky.

It’s safe to assume that most reading this here blog will be good and dead the next time a human craft explores anywhere *really* new that’s bigger than an asteroid.

So… this is it, this is the end.

Rockwell art of an early Shuttle configuration. The full-rez version has been made available for $10-level patrons at the APR Patreon.

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.

Neato.

The US Patent Office page on this.

THIS should link directly to the PDF of the patent.

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
