Many years ago at one of our club launches, someone brought a "tube" rocket made out of a single wrap of that thin insulating sheet. From what I recall, it was about 12 in in diameter and 3 feet long. It had something to support a motor mount and a launch rod up the middle. It flew about 20-30 feet up on a "D" impluse motor. I did not take any photos of this.
I am trying it out using a 3d printed motor mount. I envision three of them: two at the bottom to hold the motor tube in place, and one at the top for support.
I tried to model this in OpenRocket, but it could not compute the CP. What is the CP of just a tube?
Has anyone built/launched anything like this?
Thoughts? Design tips?
