Multi-objective optimization for Aero-Engine Fan Blade by using Genetic Algorithm

Abstract

In design of aero-engine fan blade, it is required to improve the performance such as efficiency and pressure ratio with considering several constraints such as structural strength, resonance avoidance, surge avoidance, and so on. However, it is difficult to find solutions that satisfy all constrains. In this research, feasible and improved solutions than existed solutions are found by multi-objective optimization using genetic algorithm with multiple constraints ranking.
