9 supp sheets. Velocity potential, lift force, moment, and propulsive force on two-dimensional airfoil in stream of periodically varying angle of attack are derived on basis of non-stationery incompressible potential flow theory which includes effect of continuous sheet of vortices shed from trailing edge; application of results.
