Multicriteria Optimization Of Conceptual Compressor Aerodynamic Design

Övrigt konferensbidrag, 2011

A design method is introduced that incorporates a mean-line design code and a throughflow code with an optimization environment. The scheme makes it possible to use design of experiments for rapid exploration of the design space and also multiobjective optimization. The method is then demonstrated by defining a conceptual compressor optimization problem, typical for an open rotor engine compressor. The optimizer environment is used to establish a pareto front interrelating the compressor part load surge margin and the polytropic design point efficiency.
