The aerodynamic stability of similar systems had been analyzed. There are two cases compared when pulsation wind component is Gauss random stationary process with a spectral density of Davenport, and spectral density of Kaimal.aerodynamic stabilitylinear systemstochastic parametric loadstationary processаэродинамическая устойчивостьлинейная системастохастическая параметрическая нагрузкастационарный процесс
