![]() ![]() Furthermore, it enables the cruise performance and drag divergence Mach number to be predicted with only one simulation of the cruise point, which will greatly save the computational cost of optimizations. It indicates that the drag divergence Mach number can be increased by obtaining a shock wave that is further upstream in the detailed design. Compared with Korn's equation, the discovered correlation reduces the maximum prediction error by approximately 40%. A new linear correlation is discovered and validated by existed airfoil databases. Airfoil Tools is a web site that offers various tools to search, compare and plot airfoils from different sources, such as the web, online databases or user-generated data. Correlation screening and multivariate regression are carried out to discover knowledge about the airfoil drag divergence Mach number and pressure distribution features. This paper designs a supercritical airfoil database that covers the typical free stream Mach number, angle of attack, lift coefficient, and geometry of modern transonic commercial aircraft. However, it neither reveals the key factors of fluid features on the drag divergence nor contributes to the detailed design. It is very helpful in the aircraft initial design. For example, Korn's equation predicts the airfoil drag divergence Mach number using the airfoil maximum thickness and the lift coefficient.

The group also conducts low-speed airfoil tests and research on various topics, such as propeller design, wind turbine aerodynamics, and model aircraft. Welcome to, a database of shapes, data, and other information pertinent to 2D airfoil sections.Aerodynamic rules and knowledge are often obtained through theoretical research and experiments, which have contributed greatly to aircraft design. The UIUC Applied Aerodynamics Group provides a comprehensive airfoil database of over 1,600 airfoils, including experimental data, design methods, and usage examples.
