Combustion Chamber

2025 | Liquid Engine 3

Joining the liquid engine subteam within STAR, I specialized in manufacturing, primarily using the machine shop's lathe and mill for parts with critical dimensions and interconnected fits.

This role strongly improved my DFM and skills in creating practical drawings, building upon the concepts in classes of fits and tolerancing.

The specific subassembly these parts belong to is the injector and combustion chamber, which work together to mix and ignite liquid oxygen and kerosene, generating high-temperature, high-pressure combustion gases that produce thrust.
