Abstract:

This paper reviews the current techniques of aircraft viscous drag reduction and some of the more recent developments that have taken place in this technology. The various sources and relative contributions of aircraft drag are described including skin friction drag, pressure drag, interference drag and lift induced drag. In the discussion, emphasis is given to the physical processes that lead to these drag contributions, followed by a discussion of methods of reducing the impact of these drag sources. Finally some brief discussion is presented to show how innovative and optimized aircraft configurations can lead to drag benefits.
