Two methods of compressor blades profiling are described. Its traditional coursed method andtheoretical, both based on using symmetrical profile and middle curve. Author suggested reverse-engineering algorithmsfor both methods. For method which use more accurate theoretical method as base method suggested algorithmis described in details. Successful tests of program using this algorithm are showed. It was performed with compressorprofiles and also turbine profiles which is known as more curved.</p>Bladeprofilingfine-tuningsymmetrical profilemiddle curvereverse-engineeringalgorithmprogramЛопаткапрофилированиедоводкапрофиль симметричныйлиния средняяреверс-инжинирингалгоритмпрограмма
