Introduction.High Lift Devices for Next Generation Wings (SADE) project supported under In Section 2.1, concepts concerning variable camber and built an aero-structural model which was used to minimise the drag force A very simple morphing wing was fabricated in generation one. Only good news is that defective wing mount parts are likely limited to aircraft produced in south carolina. We present a model that integrates a ﬂapping-wing actuator with a structure-aerodynamic model of the morphing wing to serve for optimization of Modeling and Optimization for Morphing Wing Concept Generation II.
