Abstract

Recent development of a smart structures module and its successful integration with a multidisciplinary design optimization software ASTROS * and an Aeroservoelasticity (ASE) module is presented. Two application examples have been worked out to demonstrate the integrated software capability. These include the active flutter suppression of a modeled F-16 wing using piezoelectric(PZT) actuators, and the gust-load alleviation of a modeled F-18 aircraft using control surfaces. For a closed-loop system as opposed to an open-loop system, the former case shows PZT actuator enabling to stable all otherwise unstable modes, whereas in the latter case the RMS modal responses were found substantially reduced.
