Previous research at Naval Postgraduate School produced a design procedure for generating gas compressor rotor models using commercial software. This design procedure was improved upon by parameterizing the blade profiles as quadratic functions of axial distance and chord location. An objective function for compressor performance using pressure ratio, efficiency, and massflow was formulated, which applied a holistic view of quantifying the value of a compressor design. An optimization algorithm was implemented within the procedure to seek an optimal design by generating a CAD model, performing computational fluid dynamics (CFD) analysis, and iterating the design function constants toward an optimal solution. The routine found an optimal compressor design; however, inconsistencies in the CFD solution data prevented the routine from finding the expected global maximum.
