Controlled and Uncontrolled Flow Separation in Three Dimensions (Decollement de l'Ecoulement en Trois Dimensions, Controle et Non-controle)

Abstract

The advantages of swept, sharp edges that generate controlled (or fixed) three-dimensional flow separations on a vehicle, because of the qualitatively unchanging flowfield developed throughout the range of flight conditions are promoted in perference to allowing uncontrolled (or unfixed) separations. The three-dimensional viscous flowfields and vortical interactions about typical components such as delta wings and bodies at incidence are discussed, in apposition to their use on selected examples of current flight vehicles.
