L1 Certification Rocket
In ProgressWhy
I wanted to design and build a high-powered rocket that meets the requirements for NAR L1 certification, while creating a fully documented design that future SEDS Redlands Chapter members can build on. I also wanted most of the components to be manufactured in-house at the Redlands Makerspace at a low cost.
How
Rocketry leaves no margin for error, so I validated the engineering before ordering any parts. I finalized the design in OpenRocket to reach a stability of 1.5 cal, then took the 2D design into Onshape to build a full CAD assembly and ran AirShaper CFD simulations to confirm an aerodynamic ogive nosecone. The nosecone and tube coupler were 3D printed in ABS, while the centering rings and fins were laser-cut from 3 mm plywood at the University of Redlands Makerspace. SEDS members helped with assembly, including epoxying the fins to the centering ring to withstand flight loads.
Results
The rocket is fully assembled and awaiting its November launch date, where I hope to earn my NAR L1 certification. The complete design documentation will be passed down to future SEDS Redlands Chapter members.
