CATALOG DATA:
Fluid-structure interaction, steady and unsteady aerodynamic loadings, static and dynamic aeroelasticity, flutter and forced vibration analysis, application to airplane structures, civil engineering structures, rotorcrafts, and turbomachines.

TEXTBOOK:
Dowell, E.H., et al., A Modern Course in Aeroelasticity, Sijthoff and Noordhoff, 1980.

GOALS:
The course provides an introduction to fluid-structure interaction and a background for unsteady aerodynamic loadings and structural dynamics for students without experience in that area. Both static and dynamic aeroelastic phenomena are considered. Analytical methods in aeroelasticity are demonstrated by selected problems in flutter and forced vibration of airfoils and wings, civil engineering structures, and turbomachines blades.

PREREQUISITES:
Consent of instructor; steady airfoil aerodynamics, torsion and bending of beams, dynamics of rigid bodies, elementary matrix methods, ordinary and partial differential equations.

Topics:

• Fluid-structure interaction phenomena.
• Steady and unsteady aerodynamic response of an airfoil.
• Static aeroelastic behavior of a typical airfoil section, divergence and reversal.
• Simplified aircraft, wing-body-tail model for static behavior.
• Static aeroelastic behavior of finite wings.
• Effects of sweep.
• Introduction to structural dynamics, discrete and continuous structures.
• Moda methods.
• Flutter: airfoils and wings, bridges, turbomachine blades.
• Forced vibration: airfoils and wings, bridges, turbomachine blades.
• Stall and bluff-body flutter.
