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.
