520 _aAeroelasticity is an essential discipline for the design of airplanes, unmanned systems, and innovative configurations. This book introduces the subject of unsteady aerodynamics and dynamic aeroelasticity by presenting industry-standard techniques, such as the Doublet Lattice Method for nonplanar wing systems. “Introduction to Unsteady Aerodynamics and Dynamic Aeroelasticity'' is a useful reference for aerospace engineers and users of NASTRAN and ZAERO but is also an excellent complementary textbook for senior undergraduate and graduate students. Fully develops the theory of acceleration potential, fundamental to the unsteady aerodynamics behind the Doublet Lattice Method; Explains fully the industry-standard unsteady aerodynamics capability: the Doublet Lattice Method; Theoretically develops various state-of-the-art methods to determine the flutter point; Clarifies the differences between ``cantilever flutter’’ and ``body freedom flutter’’; Introduces the nonlinear aeroelasticity of Joined Wings and innovative wing systems. Luciano Demasi has written a comprehensive and insightful book on aeroelasticity as practiced today. The careful and deep attention to the fundamentals and a unique and valuable discussion of the implementation of Doublet Lattice aerodynamics are special features of the book. The author also ranges over a number of additional topics including current and promising aircraft and wing concepts that bring new challenges to the aeroelastician. The student new to the topic as well as the experienced practitioner will find much to ponder and benefit from a careful reading of this text. — Prof. Earl Dowell, Duke University.
