Making Ammonia Perchlorate (APCP) Rocket Engines
Рет қаралды 11,381
Күн бұрынIt's one of the best composites for a solid rocket engine, so much so that it made up the 2 booster engines for the Space Shuttle. I use off the shelf silicone in this composite. As there were no clear instructions that I could find, I went through several mix iterations before I found one that worked successfully. It turned out to be the fastest, most powerful, DIY rocket engine I've made so far. And, it turned out to be waterproof. So, that was weird.

I used to live in Cape Canaveral Florida. As kids we would find big chunks of rubber on the beach. If you lit it on fire it would just go off. Bright white light up the road. It was fule from rockets that had exploded. From who knows when.

Ok, I got my Ap off of Amazon back in 2012, as far as I remember that was the date. I'm out at this point and wanted to order more, no luck! Amazon used to have 90 micron ap available. Where are you getting yours? Pyroachemsource? And has it raises any concerns, as far as getting it? I have no clue why Amazon no longer offers it, but I can only imagine. Anyway always enjoy your videos Brother !
@cranialconstruction2218 Жыл бұрын
Yes, Amazon has stopped carrying some of these chemicals. Especially those that can be used in pyrotechnics, rocket engines, etc. I first got mine there several years ago and that's what I'm using in the video. When I need to reorder I'm not entirely sure where it will come from, but a chemical warehouse is high on the list.

3 KClO4 + 8 Al → 3 KCl + 4 Al2O. The stoichiometric ratio is 34.2% aluminum and 65.8% perchlorate by mass. A ratio of seven parts potassium perchlorate to three parts dark pyro aluminium is the composition used by most pyrotechnicians

Yes, that is correct. You do need to mix in the right ratios for it to work properly. Also, it is silicone used, not silicon. They are two different things.

For anyone that wants to make the real stuff, HTPB resin is available for purchase at the RCS Store online, I got a gallon of it last year and still have 90% of it left even after making dozens of rockets. It's not the cheapest stuff (about $250/gallon including the catalyst) but the difference it makes over silicone is huge, it has a much more stable burn and is far easier to mold into grains, and provides more thrust as well. If you dont live in the US you're shit out of luck unfortunately, the RCS Store doesn't ship outside of the lower 48.

That's a difficult question. By nature, AP is expensive stuff. AP is sold in large quantities most often so finding sellers of smaller amounts is key. Amazon has fair prices and allows purchases of smaller amounts, less than 0.5 kg.

Casing too weak - a thin plastic tube cannot withstand the pressure being created. Also (and related to first point), your nozzle is too small! Even a PN/sugar motor generates 60 to 72 atmospheres of pressure (about 1000psi)!
@cranialconstruction2218 8 ай бұрын
Yep. This was a video on firsts. Just to see if an APCP fuel could be made from over the counter silicone. To find the best ratios. And then to try and launch an engine. I had no idea that the thrust would be that significantly stronger than anything I had worked with to this point. I will make an updated video now that I have worked with this fuel (quite a bit since this video just testing) and have some experience.
