Boundary Layer Theory: A Study of the Application of the Theory to Aeronautical Problems

A STUDY of the flow in the immediate neighbourhood of the surface of a wing or body has often provided an explanation of apparent inconsistencies in the evidence obtained from tests in different wind tunnels or from model and full scale experiments. It is of the highest importance in investigations of critical changes in aerodynamic forces such as occur when a wing stalls, of interference effects and of oscillatory motions caused wholly or partially by aerodynamic forces.
