Abstract : A brief review is made of the available information concerning the flow fluctuations and instabilities arising from shock-induced separation in the flow over aerofoils and wings. The influence this phenomenon has on the oscillatory behaviour of aerofoils and control surfaces is also briefly discussed. A more detailed consideration is devoted to a recent investigation into the part played by shock-induced separation in the instability of a control surface. (Author)
