I feel like there's plenty of tech that we have real world functional devices for case studies before we start adding nuclear shape charges. For one multi stage fission implosion devices would be great,Tsar Bomba and Castle Bravo being the obvious two tests to point at. Nuclear pulse propulsion and casaba howitzers would be cool though if the math supports it.
If I wanted to do a laser with a nuclear lamp I think I'd just park a pair of kiloton mirrors in low orbit over the sun. What are you going to do? Build a bigger laser? Try to destroy the mirrors with micro missiles? Wait until the laser runs out of fusible material?
Weren't Castle Bravo and Tsar Bomba Teller-Ulam devices? |

Weren't Castle Bravo and Tsar Bomba Teller-Ulam devices? That's what I meant by 'multi stage'. I guess I should have been more specific if there's a wide verity of kinds of multi stage nuke that I don't know about? Or if 'multi stage' just wasn't an accurate description of the Teller Ulam firing sequence? I think I referred to them as 'multi stage' in a broad, general sense because I remember Tsar Bomba also having a tertiary fusion cylinder after the secondary. I'd have to relocate my source to cite that, it might have been another test.

airc777Teller-Ulam devices and even some aspects (explosive lenses, the equations we have have been more or less guesstimated) of single stage fission nukes are NOT modelled by CDE due to math and physical models still being kept secret. We won't get Teller-Ulam devices.

We won't get Teller-Ulam devices. We don't have enough information from enough tests to approximate yield? Then how are we speculating on casaba howitzers and Orion drives? |

I'm confused because while there are trade secrets involved in most of the things modeled in this we can approximate conservative models relatively easily. You won't find many pictures on the internet of a chemical rocket with the camera pointed up the rocket nozzle showing what the injectors look like, but we have no issue making a game model that approximates engines because the energy density of the reaction mass and the engines flow rate are known values.
The energy density of fissile and fusible materials is a known value. Functionally, for our purposes, the controlled knowledge is just the achievable efficiencies, for our purposes the exact dimensions of the internals is already arbitrary. (As we don't have all necessary information relevant to the construction of boosted fission devices modeled, we just used an estimate.) So what's to stop us from looking at all of the publicly available information on declassified tests, coming to a consensus on a conservative estimate of an achievable efficiency, and then creating a model with some arbitrary slider bars?

Whereas guest posting was useful for some people.
Sadly, I'm not sure what, if anything, can be done to save guest posting now that spammers have discovered it.

Given that it's nuclear EFP thread, I would sure vape someone, alright.
