Nonsteady aerodynamics of lifting and non-lifting surfaces

Abstract

The classical theory for unsteady potential flow models in the supersonic, subsonic and transonic mach number ranges is presented including representative computational methods and results. The discussion with the simplest case of supersonic flow in two dimensions and then proceeds to consider the generalization to three dimensional flow, then subsonic flow and finally transonic flow. The discussion proceeds from the simplest to the most complex case and does not follow the historical order in which these subjects were treated. Also fourier and laplace transforms are used to obtain the key results even though other methods were used historically to first derive the governing integral equations.
