Introduction to Aeroelasticity introduces the classical topics of aeroelasticity, beginning with elastic structural modeling and the way that wing and tail structures can diverge and deform due to aerodynamic, inertial, and control-surface deflections. After describing flutter, first with an airfoil example with increasing complexity, and then for flutter predictions of finite wings with and without control surfaces, the book expands into single-degree-of-freedom flutter. It introduces cable "galloping," Aeolian flutter, plunging and pitching stall flutter. The book presents equation derivations in a step-by-step fashion, complemented by several numerical and historical examples. The book is intended for senior undergraduate and graduate aerospace engineering students taking introductory courses in Aeroelasticity. Instructors will be able to utilize a Solutions Manual and Figure Slides for their course.
