Abstract: The aerodynamic design method of aspirated compressor rotor blade was investigated. An iterated design method was adopted by using the results of three-dimensional (3-D) flow field calculations to provide loss calculation model of S₂ flow surface, thus improving S₂ flow surface calculation precision. The optimization design software in which the suction parameters and profile parameters were related to the design of two-dimensional random rotating surface profiles and 3-D blades was developed, by combining the optimization method and numerical simulation method. An aspirated compressor rotor was designed by this software, and the numerical simulation results show that its total pressure ratio is 1.631 and isentropic efficiency is 0.965 at design point under the condition of 0.86 tip blades loading, and high aerodynamic performance is achieved.
