Quote from: Weaver on March 09, 2025, 02:39:39 PMThe wierd thing about HTP is that it actually gets safer the purer it is, at least in terms of explosion risk. It's the impurities that cause it to spontaneously decompose: if you're walking past a tank of HTP and it goes "BLOOP", time for a running shoe test. Less impurities, less risk. The 95-98% stuff you can get now is significantly safer. 80-85% is in whatever the opposite of a sweet spot is: concentrated enough to have a ton of stored energy, impure enough to release it all at once if it feels like it. Or you look at it in the wrong tone of voice. Or it's the wrong sort of Thursday... :o


I am guessing that you read Douglas Adams

Gondor


I do, but that wasn't what I was thinking of to be honest. The "bloop" thing and "running shoes" is cribbed from Ignition! by John D. Clark, a scientist who spent his career working on rocket fuels. It's a highly amusing and entertaining book, for such a technical subject.


I didn't know about that so I have just bought a copy  :thumbsup:

I had been thinking more of the "Or you look at it in the wrong tone of voice. Or it's the wrong sort of Thursday... :o " section, sounds very much Hitch-Hiker Guide.

Quote from: sandiego89 on March 09, 2025, 04:30:39 PMThe Hydrogen peroxide and kerosene fueled Blue Steel (conveniently wrapped around a 1+ Megaton warhead!) might count as a bad idea in itself!

To show that I am an equal opportunist on bad taste/ideas, I had been thinking of a fuming nitric acid fueled school bus in the 1950's US application, but I had the Omnibus in the stash.....   


My Division Director at BR was the Control Systems engineer on the Blue Steel, and when I told him I'd worked in 'that hangar' he looked horrified and said 'They're not STILL using HTP are they?' but I was able to assure him that they weren't.  ;D

I always wondered about the 'Red Fuming Nitric Acid' fuel used in the US SAMs, it was the Nike Ajax that used that as an oxidiser, wasn't it?

The Russian still use HTP for the maneuvering thrusters on the Soyuz spacecraft. It's also used in some high-performance torpedoes, which is terrifying.

RFNA and related mixtures was used in Nike Ajax and a bunch of other ballistic missiles and space launchers. A spill results in a cloud of nitric acid vapour which eats your lungs in the worst way possible. If you see a rusty red cloud anywhere near a rocket or missile site: running shoes.

Make sure you are running into the wind or you'll just die tired.

Inspiration is where you find it.
And there's nothing wrong with emulation.  ;)

I also agree; the comments in this thread are worth the reading, let alone the model being built!  :thumbsup:  :thumbsup:

Yes, all this talk is MUCH more interesting than what I remember of my High School Chemistry Class. 

Second coat of primer on, no the final bus will not be pink.  I have read that pink primer can make some final colors pop.  My first try.

I sprayed  a front guard for one of my cars exactly the same way yrs ago 😆
No idea what the bush was but it might have been a slightly different green ..ie canary yellow 💛  ;D

Pale pink primer certainly works well with yellow
Do not condemn the judgement of another because it differs from your own. You may both be wrong.

Keeping it that colour would work as a warning to other motorists...
