Compressor blade profile reverse-engineering: building of middle curve and symmetrical profile

Abstract


Is discussed one of the problems for fine-tuning and redesigning blade machines - reverse designing task (reverse-engineering task). Two methods of compressor blades profiling are described. It’s traditional coursed method and theoretical, both based on using symmetrical profile and middle curve. Author suggested reverse-engineering algorithms for both methods. For method which use more accurate theoretical method as base method suggested algorithm is described in details. Successful tests of program using this algorithm are showed. It was performed with compressor profiles and also turbine profiles which is known as more curved.
