Active Flutter Suppression Using Astros With Smart Structures and Ase Modules

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. Application examples have been worked out to demonstrate the integrated software capability. These include the neural net based active flutter suppression of a modeled F-16 wing using piezoelectric(PZT) actuators the gust-load alleviation of a modeled F-l8 aircraft using control surfaces and trim drag reduction of TOMAHAWK with/without battle damage using PZT actuators.
