An open source tool to generate Jet Engine compressors▲35
Hi everyone started this project a year ago to generate the CAD for a Jet Engine Axial Compressor. I am now open sourcing this tool that can take in a JSON file with specs and generate the CAD assembly. Still has a lot of work to improve designs but there isn't anything the Open Source community can't accomplish!
