TurboJet Model Rocket (Pringles Remix)

thingiverse

WARNING: This rocket is likely too heavy for a C engine. As such, I actually do not recommend building this one. See my other Turbojet rocket based on a BT-80 instead. It may be a little self-indulgent to post a remix of your own thing, but there are extenuating circumstances that I arbitrarily decided make it necessary to do a remix so that I can excuse my self-indulgence. My original, made with a BT-80 body tube for the outer tube, flew perfectly. It also perfectly landed at the top of a 60-foot tree from which I have been unable to recover it (and I have tried). I like that rocket; I wanted to build another. I did not, however, have any more BT-80 body tube pieces laying around. Having designed several other rockets based on Pringles cans, converting this one to use a Pringles Can seemed natural. To build this rocket you will need: * 1 Pringles can with the ends cut off. You can cut it to the length you want, but I used almost the entire can. Longer rockets tend to be more stable without having to add as much weight to the nose. * 1 Tube from a roll of Aluminum Foil. Mine came from a Reynold's Wrap Heavy Duty 50sq/ft roll. Other rolls may use the same tube. You'll have to cut this tube to length once you test fit the fins and intake to the Pringles can. The Aluminum Foil tube should be flush at both ends of those plastic parts. * 1 Each of the two parts on this thing. * The nose cone, nosecone base, motor tube, and retainer ring from the original Turbojet rocket this thing is a remix of. * Something to weight the nose with and knowledge on how to swing test a rocket to check for stability (YouTube has videos on this). I use BB's in the nose and epoxy them in once I have the right weight. I don't glue the nosecone to the base until this balancing is done. For this rocket, I had to fill the nosecone with BBs. So it required a lot of weight. But then I also covered the fins with Epoxy to smooth them, which added weight to the rear. I don't recommend smoothing the fins this way. LAUNCH REPORT 7/5/2019: Launched on a C6-5. Because I weighted the nose so much, the motor didn't really have the power necessary for a stable flight. I actually do NOT recommend building this rocket as currently designed unless you plan on putting an 18mm Aerotech D motor in it. Even then, do a stability swing test. My previous Turbojet, based on the BT-80 body tube, flew so much better.
