Helium Cryogenic Expansion Unit

Using TurboTides software, the impeller and nozzle of the expander were fully optimized with an isentropic efficiency optimization goal, while meeting aerodynamic, structural, and other constraints. The rotor dynamics were verified through shaft system modeling, and thermal insulation structures were also designed.
