Kobelev] In this paper, the influence of small structural perturbation on a linear, nonconservative dynamical system exhibiting fractional bifurcation was investigated. In considering design problems for nonconservative systems, the integral structural characteristics as fundamental frequencies, critical loads for instability, and the sensitivity analysis play an important part. In this paper, the influence of small perturbation on a linear, nonconservative dynamical system exhibiting a flutter type bifurcation was investigated. The hereditary damping is described by means of fractional derivatives. To study the dynamical instability for nonconservative governing equations with fractional damping, the method of auxiliary eigenvalue problem is applied. The stability conditions of generalized Lyapunov type for the system with hereditary damping were derived. A new analytical framework for the coupled optimization of aero-structural, fractionally damped systems is presented. The approach to obtain aerodynamic sensitivities is based on adjoint systems.
