Parameterization design method for turbine cooling blade turbulent flow rib cooling structure

According to the parameterization design method for the turbine cooling blade turbulent flow rib cooling structure, data points of an original blade profile outer section molded line are extracted, expansion and offset are conducted, data of an inner molded line and a rib height inner molded line can be obtained, and by giving turbulent flow rib positioning parameters, the cooling structure of the turbine cooling blade turbulent flow rib can be obtained. Each rib molded line positioning point of the turbulent flow rib in the radial direction of the blade can be automatically obtained by compiling a UG OPEN API C language, a. Dll file can be executed by compiling the UG OPEN API C language, and automatic modeling can be carried out by calling the file every time through UG by utilizing commands of curve connection, projection, stretching, curve group passing and the like of the UG OPEN API C language. According to the method, the bending and twisting characteristics of the blade can be self-adapted, feature pa
