Aeroelasticity 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.

The theoretical material includes:

•        Fundamental equations of aerodynamics.

•        Concepts of Velocity and Acceleration Potentials.

•        Theory of small perturbations.

•        Virtual displacements and work, Hamilton's Principle, and Lagrange's Equations.

        Aeroelastic equations expressed in the time, Laplace, and Fourier domains.

        Concept of Generalized Aerodynamic Force Matrix.

•        Complete derivation of the nonplanar kernel for unsteady aerodynamic analyses.

        Detailed derivation of the Doublet Lattice Method.

•        Linear Time-Invariant systems and stability analysis.

•        Rational function approximation for the generalized aerodynamic force matrix.

•        Fluid-structure boundary conditions and splining.

•        Root locus technique.

        Techniques to find the flutter point: k, k-E, p-k, non-iterative p-k, g, second-order g, GAAM, p, p-L, p-p, and CV methods.
