Abstract
The paper focuses on a multi-parameter optimization of an impeller for an ultra-small-scale gas turbine with an electric power output of 300W. The main innovative feature of the presented gas turbine is its single-piece rotor, produced by additive manufacturing. In the scope of the current optimization study, different manufacturing materials and technologies are evaluated. Additive manufacturing approach is further utilized towards printing a hollow impeller geometry, thus creating an internal cavity that has positive impact on the micro gas turbine performance. The goal of the optimization is to change the cavity shape towards improved thermal, rotordynamic and structural performance via genetic algorithm.
