商品簡介
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.
