Hybrid Rocket Engine
2025 – presentA paraffin-wax hybrid engine with a 304 stainless steel combustion chamber, built with the Kinnick aerospace club. It runs on paraffin and pressurized air and burns with a blue flame.
- Sized the chamber wall using Lamé thick-wall equations and safety factors against the calculated chamber pressure.
- Ran structural FEA and k-ω SST CFD in SimScale, and spent a lot of time fixing boundary conditions and meshes.
- Wrote a Python script that takes chamber conditions and finds the best throat size for a bell nozzle.
- Modeled the assembly in Fusion 360 and sized the compressed-air oxidizer system.
- Bench-tested air, propane, and paraffin-kerosene fuel setups.
