Model Rocket - Eggloft Altitude Competition - PELA18-V1.0

thingiverse

I recently attended the 60th annual National Association of Rocketry competition, where I set out to prove that printed models can be competitive. The typical models in this event are made from paper, balsa, plywood, fiberglass, and/or vacuformed plastic, with printing being rarely used except for a few printed nosecones and details on scale models. This model is 100% printed in ABS and achieved a second-place altitude of 274 meters using an Estes 'C' motor, just six meters shy of first place. As this was my first model rocket flight in over 30 years, I was moderately pleased with the result. For an old guy like me, "moderately pleased" translates to being wildly ecstatic. The goal of the Eggloft event is to fly a large egg to the highest possible altitude and bring it back unbroken. This model is designed for 18 mm model rocket motors, making it suitable for 'B', 'C', and 'D' motor class events. With more experience under my belt and some fine-tuning of the model, I expect it can achieve better results, and printed models will likely find a place in competitions. http://nar.org http://nar.org/site/naram-60/ My other projects: https://www.thingiverse.com/garyacrowellsr/designs My model rocket projects: https://www.thingiverse.com/garyacrowellsr/collections/model-rockets-vcp My model rocket collection: https://www.thingiverse.com/garyacrowellsr/collections/model-rockets My collections: https://www.thingiverse.com/garyacrowellsr/collections
