Design And Testing

Flutter of the airplane is serious problem which is carefully investigated during design and testing both computationally and experimentally. The lightweight plane dynamics is however influenced by pilot, by his muscular transfer function. This study shortly describes results of experimental investigation of pilot's modal characteristics from 1 Hz up to 70 Hz. Next discusses the pilot influence on modal parameters of longitudinal flight control system of lightweight airplane. The change is aimed on the natural frequency and damping. This study also discusses the change of flutter velocity with dependence of new modal parameters influenced by pilot. Including a comparison with the current methodology - free and blocked longitudinal flight control system.
