PIEZOELECTRIC AND VISCOELASTIC CONTROL OF LIFTING SURFACE AERODYNAMIC DERIVATIVES AND AILERON REVERSAL

The effects of viscoelastic piezoelectric damping on the control of aerodynamic derivatives and of aileron reversal time retardation is formulated and evaluated. It is shown that significant control can be achieved with devices which add insignificant weight to flight vehicles, i. e. creep divergence and aileron reversal can be delayed in time.
