So I have been wanting to build a two-stage rocket for some time now. I have been building mostly 1/10th scale rockets and I did start a Semroc Nike Tomahawk but have run into some technical/design issues of the gap-staged booster so it's hanging out while my brain sifts thru the best way to do it.
In the meanwhile I have been thinking about building a simplier two-stage rocket. My first design is a direct staged designed based on D12 engines. I was a little concerned about the altitude so I was thinking about a chute release so I had a thread about that. Here's a screen snap of the rocket:
I like it but I saw the Estes Red Nova and thought that would be a nice looking upscale (1.64 like the one above) so I drew it up, sans the nose cone. It was also based on the Estes 24mm motors. It has a gap of about three inches between engine, nothing too big or complicated. I did not draw up just the booster to see if it will tumble or not.
Then I started thinking about how I like the looks of the Nike X and how I'd probably build one if it was slightly larger. I decided to draw one up and I remembered about the altitude issue with rocket one so I thought if I build it slightly larger that would help with decreasing the altitude and the larger diameter would also help with a chute release if it turns out I need one, like if I use E engines instead of Ds so I drew it up with a two inch tube. This has a larger gap stage though with about 6 inches between motors. I did draw just the booster and the CP and CG are very close. I think it would tumble based on what I've read but I would like to get the expert's opinions on that. The caliber is good on just the sustainer as well.
I tried googling Nike X two stage and to my surprise, turned up nothing. So I'd like to here any thoughts on this Nike X two stage design if anyone would care to share their thoughts.
Thanks,
