Abstract

The application of gas dynamics concepts can clarify and explain many aspects of aerodynamic phenomena. In the case of friction drag, this approach suggests some new possibilities for its reduction, such as the use of "ultra-smooth" surfaces having specific physical and chemical characteristics used in conjunction with a noble gas lubricating layer. Such possibilities are discussed in the text which, owing to the multidisciplinary knowledge involved, is kept at a conceptual and heuristic level.
