The study for the dynamics of aeroelastic system can be best illustrated by analyzing a generic aeroelastic system: the typical section. Such approach will be instructive as a device for exploring the mathematical tools and the physical content associated with the system. The present chapter elaborates dynamic aeroelasticity and flutter of typical section. Basic approach for the treatment of the dynamic aeroelasticity of a typical section will be discussed. Then a review will be made on the theoretical foundation of flutter stability for binary-bending-torsion flutter of typical section. The final section provides an example of the basic approach by elaboration to some detail of a case study on a parametric study on aeroelastic stability and flutter characteristics of aircraft wings as a case study. For the elaboration of dynamic aeroelasticity and flutter and review of the theoretical foundation for flutter stability for binary-bending-torsion flutter of typical section, the review presented here follows closely the elaboration in Zwaan (Zwaan [1]) and Mark R. Pletzer (Ed) (Max R Platzer, Ed., AGARD MANUAL on Aeroelasncity in Axial-Flow Turbomachines Volume 2, Structural Dynamics and Aeroelasticity, AGARD-AG-298-Vol-2.) for instructiveness. As instructive illustration, the case study is drawn from the author’s work (Djojodihardjo, H and Yee, H H, Parametric Study of The Flutter Characteristics of Transport Aircraft Wings, Proceedings of AEROTECH-II 2007 Conference on Aerospace Technology of XXI Century, 20–21 June 2007, Kuala Lumpur; Djojodihardjo, H and Yee, H H, Parametric Study of The Flutter Characteristics of Transport Aircraft Wings, Proceedings of AEROTECH-II 2007 Conference on Aerospace Technology of XXI Century, 20–21 June 2007, Kuala Lumpur). For conceptual study purposes, it would be of advantage to look into a simple method that may give instructive results. In this connection, various modern transport aircrafts are classified and investigated in view of their structural dynamic and aeroelastic characteristics of their wing structure. The basic philosophy and formulation of flutter phenomena as reflected in the generic binary flutter problem is revisited and reflected to real aircraft for general understanding and conceptual design purposes.
