Abstract
In the present paper, the optimum design method of composite plate wings for aeroelastic characteristics is examined. First, the minimum weight design using real-coded genetic algorithm is treated. Lamination parameters are used as design variables in this optimization procedure. Next, the active flutter suppression using piezoelectric actuators/sensors is treated. PVDF films are used as a modal transducer for identifying specific modes in vibration measurement, and PZT actuators are used as actuators of flutter suppression. The validity of these design approaches is examined through the numerical examples.
