Country A weaponizes this, spreads it in mass throughout large cities in Country B over 2~3 years. (especially if they can get the onset time down to 5~10 years) Wait for Country B to undergo massive social stress/disorder when a significant % of the population starts quickly developing neurological issues. If done right that would be stupidly hard to track down.

I figured the Dangerous Chemisty Thread might have some info on this; I am looking for some info on historical Soviet engines that Glushko worked on using weird propellants. Specifically, I'm interested in the RD-301, RD-302, RD-303, RD-350, RD-501, RD-502, RD-510, RD-511, RD-550, and RD-560. The first four are fluorine engines, the rest use hydrogen peroxide in combination with some other stuff (such as pentaborane). I haven't been able to find much beyond what is in this; http://faculty.fordham.edu/siddiqi/writings/p17_siddiqi_glushko_rocket_engines_2001.pdf document (Table 3). Thanks

Does anyone know what would happen if weaponized prions in a carrier medium were dispersed by explosive munitions? Sorry if this ofends anyone I just thought that would be a funny thing haha. Is there any data on the environmental persistence or median lethal concentration of airborne replicating neural proteins in particles per square meter? I just want to see it for a few laughs ha ha. Another thing I am wondering is whether they have a detectable odor haha I am just curious for laughs haha

Mad cow was aerosolized the hell out of in British meat processing plants where they blended the poo poo put of brains for animal food. I think it was pretty well contained to the liquid droplets which aren't very motive in the grand scheme. Sucks if you worked there without a respirator though.

I'm reading Ignition, and tell me, why did people give up on the idea of a ram-rocket? You know, concocting some sort of monopropellant who's combustion products could then be used as fuel in a ramjet, once it got up to speed? I mean, that's like two rockets in one! I think I know how uber can make its aerial ped transport system a reality

The British Meteor air-to-air missile actually more or less uses this idea. It uses a conventional booster stage inside the motor; while getting the missile up to speed, it ignites the main fuel grain, which is oxidizer-poor and basically a gas generator. quote:The gas generator contains an oxygen deficient composite solid propellant which produces a hot, fuel-rich gas which auto-ignites in the air which has been decelerated and compressed by the intakes. The high energy boron-loaded propellant provides a roughly threefold increase in specific impulse compared to conventional solid rocket motors. When it enters service it will yield a no-escape zone more than three times greater than that of the current AIM-120 AMRAAM used by Eurofighter Typhoon-equipped airforces. True to form, it uses boron compounds.

Oof, I had an Uber driver once whose friend had that. It sounded horrible. My "favorite" "weaponized for fiction" disease is the transmissible version of Lesch-Nyhan Syndrome from The Cobra Event. It's not that good a book, but it does have a scene where a pathologist gets infected during an autopsy, cuts his own face half off, peels it down, and gnaws on it. (Spoilered for body horror.) I remember borrowing it from my mom to read on a road trip, and blurting out, "HOLY CRAP THAT JUST HAPPENED," to which she laughed out of knowing exactly what I was reading at that moment. Which caused my non-reader dad to ask what we were talking about, leading us to explain why we read poo poo with self-cannibalism caused by terrorist microbiologists.

Data Graham posted:Or, y'know, just look at those collapsing pressure vessels upthread. That is some violent poo poo. Yeah, 15psi is not an insignificant amount of force. Apparently somebody did actually attempt a vacuum zeppelin, it went about as well as you'd expect. Ravenfood posted:Thanks to the zeppelin effort-posts I did some looking and the USS Akron was designed to be a flying aircraft carrier. Looking at pictures of it, I can't see any launch/landing areas, so how the gently caress did this glorious scifi monstrosity loving work? The airplanes hooked onto trapezes hanging out the bottom. It was sketchy as hell and they never got it working right. It was like trapping on a carrier ... but the other way around. (i.e. crashing into it from underneath rather than above)

And they liked the idea so well they tried it with bombers and fighters in the 50's. The idea was for the bombers to carry their own fighter escorts on long missions before better fuel efficiency and in flight refueling were developed. The XF-85 Goblin was hooked to a trapeze under a B-29. The Goblin lives up to the adage about if a plane looks right it will fly right. As in it did neither. Oddly, they got it working out well enough that for a couple of years they used GRB-36 bombers (look up a pic of this monster) and RF-84K recon fighters for strategic reconnaissance. This was developed to extend the range of the RFs so the bomber would haul it to Soviet airspace, the RF would detach, zip off to take pictures and then re-attach for the trip home. It was dropped when in flight refueling and the U-2 proved more useful.

So I just finished bathroom-reading Ignition! last night, and I'm curious - how much has liquid propellants advanced since his slightly upbeat-yet-morose conclusion of all of his ilk effectively putting themselves out of a job? I'm guessing nanoparticles is the new boron? Also, I remember one of the only positive things ever said about the Goblin was "it'd give the Russians something else to shoot at."

The Russians were doing it a couple of decades earlier:  The Nazis also had the 'Mistel', but in this case the pilot sat in the fighter and flew the combination and the 'bomber' was packed with explosives to make, well, a giant bomb.

I'm guessing nanoparticles is the new boron? Several Russian and Chinese rockets use UDMH and nitrogen tetraoxide which has the advantage of being hypergolic and not cryogenic, but the disadvantage of being highly toxic. Some western rockets such as the Delta II and Ariane 5 use some variantion of UDMH/Hydrazine and N2O4 for upper stages though. Liquid methane and liquid oxygen (metalox) is gaining popularity especially for reusable rocket engines as it burns cleaner than kerosene and can in theory be produced on other planets. Afaik there are no launch systems currently in service using it for their first stage, but both the Blue Origin New Glenn rocket and SpaceX BFR are planned to use metalox first stages.

Isn't metallic hydrogen a potnetially massive breakthrough if "stable" enough to store in a tank? More energy compared to other propellants and decaying into hydrogen on being broken up. Sounds fun!
