Note (General): In this paper, theoretical studies to predict aircraft transonic flutter phenomena are reviewed and a new practical method based on nonlinear transonic aerodynamics is proposed for estimating flutter characteristics of aircraft in their initial design phase. This analytical tool consists of two and three dimensional subsonic aerodynamic calculation corrected by two-dimensional transonic aerodynamic computations to account for the shock movement on the wing surface. The present analytical procedure is fairly good at predicting the flutter characteristics of the wing wind tunnel flutter test model of the YXX, the next commercial transport currently under study. This result indicates the wide applicability of the method to the flutter estimation of aircraft with high aspect ratio wings.
