This is the repo for the LV3 airframe. This holds everything you need to know about making a rocket out of carbon fiber. This includes CAD files, design and prototyping logs, simulation and testing data, most of all the manufacturing procedures for the carbon fiber airframe modules.
If you aren't allowed to push, send Joe or Andrew your Github username and ask for access. (This is different from getting added to the PSAS "organization".)
If you're looking to copy or build on this work check out the doc directory, especially the layup procedure and please message the people who have committed frequently/recently with any questions (or better yet, make an issue with your question).
If you want some quick physical specifications on the airframe, checkout the quick facts. For more detailed info, we have a model for OpenRocket and a model for SolidWorks.
If you want to work on the CAD model, you'll need to have the dependencies cloned to the same directory as this repo. So, something like
PSAS
├── lv3.0-airframe
├── lv3.0-recovery
├── lv3.0-camera-ring
├── lv3.0-umbilical-ring
├── sw-cad-airframe-nsr
└── reaction-control
You should also read the Intro to Git workshop slides if you're new to Git Also, read the OreSat contributions guide if you're new to using SolidWorks with Git.
- psas/lv3.0-recovery -- CAD and analysis for the eNSR-based recovery system
- psas/lv3.0-camera-ring -- 360 degree camera module based on the RunCam Split 2
- psas/lv3.0-umbilical-ring -- passthrough module for the umbilical and arming switches (uses same format as camera ring)
- psas/sw-cad-airframe-nsr -- Mechanical separation system for the nosecone/parachute
- psas/reaction-control -- Cold gas reaction control system
- psas/LV3-design -- Early conceptual design of LV3
psas/mme-capstone(DEPRECATED) -- One of the repositories created durring the 2014 capstone. This contains code for some of the tools they used.psas/sw-cad-carbon-fiber-process(DEPRECATED) -- Yet another repo from the 2014 team. This contains CAD for some of the tools they made.
Check out the issues list if you're looking for something to do. Keeping a TODO in the README never works out.
