Abstract:

This paper reviews the aerodynamic bebaviours of leading edge vortices on the slender-wings.The leading edge vortices are important factor to control the flow field around the slender-wing and to influence the aerodynamic characteristics of the wing.Therefore, the following problems concerning the dynamics of cortices are discussed ia details: the formation of leading edge vortex and its main flow structure; the phenomenon of the leading edge vortex breakdown and its effects on the aerodynamic characteristics of the wings; the theoretical models to depict the vortex breakdown and methods for predicting the leading edge vortex breakdown. Finally a brief review on the interactions of vortices in the flow field of the slender-wings is presented.

Key words: slender-wings, vortex-flow, aerodynamic characteristics
