The objective of this chapter is to review the boundary-integral-equation methods in potential aerodynamics of airplanes and helicopter rotors, with emphasis on the `direct velocity-potential formulation', which was introduced by Morino (1973, 1974) and further developed with his collaborators, in particular by Gennaretti (1989).

The formulation is given in terms of the velocity potential, for which an explicit treatment of the wake is required; special emphasis is given to the formulation for the wake transport.

Abstract

The objective of this chapter is to review the boundary-integral-equation methods in potential aerodynamics of airplanes and helicopter rotors, with emphasis on the `direct velocity-potential formulation', which was introduced by Morino (1973, 1974) and further developed with his collaborators, in particular by Gennaretti (1989). For the sake of clarity, the formulation is presented at levels of increasing complexity, starting with incompressible non-lifting problems and ending with the most recent developments, i.e. a boundary-integral-equation formulation for the velocity potential equation for compressible flows, in a frame of eference moving in arbitrary motion, with applications to aerodynamics of airplanes and helicopter rotors. The formulation is given in terms of the velocity potential, for which an explicit treatment of the wake is required; special emphasis is given to the formulation for the wake transport. Recently obtained numerical results are included. Other methods, in particular those by Hess and by Maskew, are also presented.
