Abstract: Oscillations of catastrophic changes of shape (clicking oscillations) of compound supporting and control surfaces interconnected in a statically indefinable manner are treated. The effect of the angle of attack on the nature of oscillations is investigated. The phase patterns of the control surface twist angle at different angles of attack are shown.

Keywords: support and control surfaces, self-oscillations, bifurcations, catastrophes, Poincaré–Andronov–Hopf bifurcation.
