Abstract
Conditions of dynamic instability at parametric resonance in an oscillatory system with three degrees of freedom, which models the motion of an elastically fixed high-drag airfoil under unsteady aerohydrodynamic loads due to the vortex trail separation, are obtained in the linear approximation.
