Anyone at the WPA winter blast do anything like this ?

This is what I would like to make but as a can shell not as a rocket .

I would like to contact members of WPA here in Az , any on this website ?

Myself and my SO plan to join WPA in Jan

So you've discovered the master's rockets!

 

I believe he likes to use rockets to ensure that his shells are oriented properly in the sky. With normal shells, you run the risk of the shell exploding at an unfavorable angle, thus marginalizing the effect you worked so hard to create.

 

According to the master, practice, precision, and consistency are critical to the success of the hobbyist.

 

Look up vh718's channel on Youtube. He has a nice video about timed ring shells.

I have question ,has anyone tried to put a spin on a mortar tube to keep the shell oriented when lighting it off.

I dont think that would work do to aerodynamics , and it might mess up the tube by putting rifling in a mortar, it could create uneven pressure around the tube a split it , but i'm no physicist, give it a try with a smaller mortar and tell us , thats how you learn , plan it out and experiment

The reason I ask I watch the NASA channel and they launch satalights with a spin to keep them from going end over end ?

Yes, I do things like that at WPA events, though I'm not that good.

 

You can orient a shell in the air by fixing a rope tail to it, length depends on the size.

I just got some Saturn missile plastic tubes sealed at one end about 1/4" id and about 2.5" long. I am going to try and do some timed report inserts at this wwb. See you there.
