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.
