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. 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.
