| Summary: | In order to meet the need of evaluating the effectiveness of airfoil drag reduction design, the calculation and uncertainty analysis method for airfoil drag coefficient considering compressibility is studied. Based on the momentum conservation equation, the method of solving the drag coefficient of a two-dimensional airfoil is theoretically derived in detail. The drag coefficient integral equation is established and optimized by converting the integrated variable. On this basis, the accurate measurement test method and uncertainty analysis method for airfoil drag coefficient are established, which provides a theoretical basis and technical means for accurate measurement and uncertainty analysis of airfoil drag coefficient in high-speed wind tunnels. |
