Abstract:
Accurate and reliable aerodynamic performance prediction of airfoil is of great significance for the development of aircrafts. With the application of computational fluid dynamics in the field of airfoil design, there are more requirements for obtaining the aerodynamic performance of airfoils in wind tunnel experiments. Aiming at the next development goal and technical plan of airfoil wind tunnel experiments, the latest progress and existing problems in the airfoil static/dynamic performance measurement technology, flow transition detection, wall interference control and correction technology in airfoil wind tunnel experiments were summarized and analyzed based on the research progress and outcomes in the National Key Laboratory of Science and Technology on Aerodynamic Design and Research. It is shown that: 1) Airfoil experiment possess its inherent particularity, and enough attention should be paid to the construction of airfoil wind tunnels and relevant equipments; 2) Modern data processing technology is an important development direction of the airfoil static/dynamic wind tunnel experimental technology; 3) The control and correction technologies of wall interference still need to be improved according to specific experimental scenes.
