Hi Again Further to the T nozle question. Does anyone know how much spin stabilsation (created by fins) would effect drag ? Its just as it looks like the T...
Congratulations on your marriage! I have only seen and tried the former (T-nozzle seats in launch tube end)--I believe if you let it float, by the time it...
To make the rocket spin you need air to push against the fins--drag. I'd bet any gain from the T-nozzle would be lost to the drag from the fins--you couldn't...
Is there a simple water rocket launcher design out there? I'm interested in biulding some rockets with my boy's group at church. Thanks for your help. David...
... Spin has been investigated scientifically, and the brief summary is that up to about a 4 degree fin angle-of-attack, you can get advantages because you can...
David Theres loads its all down to the usual questions of time effort money etc. The simplist launcher is probably a cork with a piece of pipe through it which...

We are currently building Water Rockets in my Physics class and I'm starting to get really interested as I do more and more research into the intricacies of...
You are well on your way with ideas, now you just need to build one. 30 psi is not much pressure, but you can figure out how much water (reaction mass) to use...
Hi Harrison, and welcome to our group A 'chute draped over the nose sometimes will work. Maybe the balence of the fuselage would help or hinder deploy. I...
