For a theory of the flow about an aerofoil equipped with a split flap to be satisfactory, account must be taken of the wake which is formed downstream of the combination. In this paper the wing and the flap are each represented by a flat plate and it is assumed that the pressure in the wake is constant and equal to the free stream value, i.e. (it is assumed that the wake may be represented by the region between two free stream-line which extend downstream from the trailing edges of the wi ng and the flap1) (see Fig. 1).
