A State-Of-The-Art Survey Of Two-Dimensional Airfoil Data

A survey of existing two-dimensional airfoil data has been made in order to provide the basis for developing new airfoils with particular characteristics or for comparing an existing airfoil with the current state-of-the-art. It is shown that the most significant aerodynamic characteristics are related to a few key physical parameters. It is also shown that test differences in, Reynolds numbers can seriously distort comparisons of one airfoil with another.
