    A variety of aerodynamic control devices have been used for regulating wind turbines, some of which are briefly reviewed. Leading edge slats are proposed with the twofold functions of either stabilising leading edge flow on the main aerofoil or spoiling flow when required for airbrake or torque reduction purposes. The aim of the paper is to present the theoretical basis of vortex element analyses for simulating such flows. First of all a potential flow method is presented for predicting the unstalled behaviour of a slotted aerofoil. This is extended to the vortex dynamics modelling of the fully viscous flow and applied to simulate the natural stall of the slatted aerofoil and also the deliberate use of the slat as an airbrake or spoiler.
