Flutter prediction methods for aeroelastic design optimization

The objective of the paper is to demonstrate the validity of flutter predic tions obtained using eigenvector orientations (EVO) for realistic wings use d in aircraft preliminary design. Comparisons of flutter predictions betwee n the V-g method and the EVO method are presented for an intermediate compl exity wing used in optimization studies. The results presented show that th e EVO method can predict the onset of flutter for aircraft wings with reaso nable accuracy and can he used in design optimization studies of aerospace vehicles/components.
