  • HARIKA algorithm was applied to simulate the characteristic of a ten-stage high pressure compressor. With introduction of genetic algorithm (GA), one-dimensional design parameters were selected as optimum variables, and functions containing peak efficiency and margin were used as optimization objectives. Compared with initial characteristic, peak efficiency of characteristic after optimization at designed speed increased by 12.3%, and its margin increased from 11.7% to 25.13%. Then HARIKA algorithm was used to simulate variable geometry compressor characteristics. Setting angles of inlet guide vane and first three stage stators after optimization at different engine corrected speeds were presented. The performance characteristics of compressor including peak efficiency, peak pressure and flow margin were improved to great extent. Calculation results of compressor characteristics in one-dimensional and three-dimensional were compared at engine corrected speed of 1.0, 0.9. The maximum deviation of their margin was not more than 6.25%.
