| Abstract: | In this paper,the key techniques of automatic compressor blade optimization are investigated.A parallel genetic algorithm is adopted as the numerical optimization method for its global and parallel optimization ability.The blade profile parameterization is based on geometry modification to generate controllable and reasonable blade profiles in the process of optimization.To realize the optimization in the whole work range,an objective function is set which also taken into consideration the performance at no... |
