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.
Keywords parametric resonance, dynamic stability domain, aerohydroelasticity, vortex trail, aerodynamic loads, system with three degrees of freedom, Glauert condition
