Model Rocket - Functional

thingiverse

I designed this rocket as well as the launch pad with the free software Onshape. I didn't want to design any launch lugs on this model, so therefore I designed my own custom launchpad. I used superglue too glue the feet to the pad, it works, but I still wish to redesign the feet. IMPORTANT: Make sure to launch the rocket in a safe area and make sure you're at a safe distance during launch. Also: I found the rocket to diverge very quickly from a vertical trajectory if the launch pad wasn't set straight. This rocket can be used with engines with a diameter of 18mm and a length of well over 70mm. For me the engine hole was a bit too big, so I clamped the engine with a piece of paper. It was succesfully launched using C- and D-motors with a delay charge of 3s. I used an 18 inch parachute and Klima recovery wadding. The 'hook' inside the rocket is where you can attach the shockcord. It's stronger than it looks. You can tie the parachute to the nose cone. The nose clamps right on to the rocket. I found it to be a bit tight at first, but after a few times on and off, the fit was better. Maybe sand it down. Just make sure the nose is gonna come off after the ejection charge. If you have any questions I will try my best to awnser them quickly. Also feel free to imrove this design, there is a lot to be improved!
