Twotails Posted September 23, 2009 Posted September 23, 2009 http://i789.photobucket.com/albums/yy171/T...00045rocket.jpg It was a rocket filled with Blue falling leave fuse, and some gold stars. the rocket fuel was about 80g in weight, the header was close to 50g. It was a simple BP rocket, it was launched out of a 2ft morter, and it made a interesting sound as it took flight. Its sad that it dident set off the header untill it hit the ground.

Arthur Posted September 23, 2009 Posted September 23, 2009 That was a rocket with no stick or fins, it's hardly surprising that ti flew poorly and sat on the ground. Roclets need stability, usually from a stick, fins or some spin put on by tangential jets. If it uses a mortar then it is a shell and needs lift charge.
dagabu Posted September 23, 2009 Posted September 23, 2009 Still, it was funny! I'm kind of the black sheep in my club since I like rockets and I use a two stick method for stabilization. My rockets don't wind vane as badly and I don't balance them to the end of the motor but to the end of the fuel grain. These are 3# rockets with a 4" spindle and a 5/16" nozzle opening using 1/4" x 1/2" x 24", 2x4 soft wood ripped on my table saw. I use the same wood in my dolas since they glue really well and take to water softening well for bending. I get 120 sticks from 1- 8' 2"x4". Dave
Arthur Posted September 23, 2009 Posted September 23, 2009 I've seen rockets with one stick, two sticks, 3 or 4 fins, and a short stick with a fin on the bottom, that is design and preference. A ball shell should be launched from a mortar, by a lift charge. However as you have shown a ball shell with a motor attached is unstable and doesn't travel safely.
Twotails Posted September 23, 2009 Author Posted September 23, 2009 I was kinda rushing this one, in all truth i just wanted to test it out and see where to go from there. i liked the sound this one made^^ I think i have a old model rocket kit somewere, i'll try and copy it, and adjust it to my liking. Im tempted to fill the next one with crackling microstars, or my briliant White flash mix( of corse i wont fill it full of flash). or maby filled with tiny rockets? I think the first step is to get it in the air >.<
Seymour Posted September 23, 2009 Posted September 23, 2009 Why don't you copy firework rockets and give it a stick. That's what it is...
firetech Posted September 24, 2009 Posted September 24, 2009 Yeah, Seymour is right. A little common sense here and there helps a lot in pyro. It can especially help to save your life. You have a brain, use it.
Twotails Posted September 24, 2009 Author Posted September 24, 2009 I have never used any roket type firework besides bottle rockets, also it was launced in the middle of nowhere and i was a distance of a few hundred feet. also i had no sticks the would have balanced it. I just wanted to see if it would fly.
