FINALLY SOMEONE ELSE

2020-12-01 05:21:21 UTC  

Bi prop or solids? Are you making any APCP? I'm actaully working on a propulsion test stand and some carbon composite nozzles and casings utilizing 3D printing

2020-12-01 05:26:04 UTC  

I would say that counts. This isn't just an airplane channel 🤣🤣

2020-12-01 05:28:44 UTC  

I make solid fuel engines

2020-12-01 05:29:36 UTC  

Working on a mixture, but it keeps blowing out the nozzle or exploding the body, so I need to have a bigger hole for the nozzle

2020-12-01 05:29:59 UTC  

Less thrust, but at least it won't be a flying IED

2020-12-01 05:32:59 UTC  

But no, I make basically rocket candy, but with other additives. I make my own black powder. The addition of the black powder is what's making them explode. My white powder engines, they're fine. My standard rocket candy, fine. But the addition of about 10% black powder.... Boom

2020-12-01 05:34:48 UTC  

My best engine so far went up about 300 feet, turned left, and soared completely out of sight

2020-12-01 05:35:11 UTC  

Actually, thinking of it, it had to be more than 300 feet

2020-12-01 05:35:11 UTC  

How many newtons are you getting on average?

2020-12-01 05:35:27 UTC  

I don't have a way of measuring

2020-12-01 05:35:35 UTC  

Ah gotcha

2020-12-01 05:35:46 UTC  

It's all trial and error

2020-12-01 05:35:53 UTC  

Are you running sims on Richard Nakkas xlm?

2020-12-01 05:36:01 UTC  

No

2020-12-01 05:36:06 UTC  

He has the best data base for r candy

2020-12-01 05:36:53 UTC  

Once I started making more powerful rocket candy I was plagued with nozzle blowouts

2020-12-01 05:37:28 UTC  

Ah gotcha, probably had tight throughts

2020-12-01 05:37:46 UTC  

I usually make throats 1mm bigger than deisgned for testing

2020-12-01 05:37:51 UTC  

Prevents CATOs

2020-12-01 05:37:57 UTC  

So I capped the ends and then packed clay. That resulted in it going up about 50 feet, then exploding

2020-12-01 05:38:18 UTC  

Wait are you making clay nozzles?

2020-12-01 05:38:20 UTC  

I was making my nozzels the exact size of the fuse

2020-12-01 05:38:42 UTC  

I just started to experiment with other stuff

2020-12-01 05:39:05 UTC  

But basically, yes. Still on clay

2020-12-01 05:39:23 UTC  

I don't have the capability of making metal ones

2020-12-01 05:39:32 UTC  

Haha don't worry my man

2020-12-01 05:39:36 UTC  

I got you covered

Been developing carbon/metal composed adhesive composites for non machinable SRMs

2020-12-01 05:40:59 UTC  

And 3D printed mandrels

2020-12-01 05:41:37 UTC  

But the last test I did was a PVC engine (3/4) but I capped the end, then packed with clay, then fuel, then clay, then cap again. Drilled the nozzel through the cap and clay

2020-12-01 05:41:42 UTC  

It was a flying IED

2020-12-01 05:42:27 UTC  

No recovery charge

2020-12-01 05:43:07 UTC  

I make rockets out of pool noodles and anything laying around, so I don't care if I lose it, although that's not preferable

2020-12-01 05:44:36 UTC  

I don't recommend PVC

2020-12-01 05:44:55 UTC  

Have you seen what it did to a lot of rocketers

2020-12-01 05:45:07 UTC  

It's X-ray transparent

2020-12-01 05:45:21 UTC  

So shrapnel wounds meant they can't get em all out at the ER

2020-12-01 05:49:56 UTC  

I normally wrap them so if they should explode they won't send shrapnel everywhere
