Aeroelasticity

Aeroelasticity. Instructor: Prof. C. Venkatesan, Department of Aerospace Engineering, IIT Kanpur. Aeroelasticity studies the interactions between the inertial, elastic, and aerodynamic forces that occur when an elastic body is exposed to a fluid flow. Topics covered in this course include: Aeroelastic problems; Deformation of structures and influence coefficients; Energy method; Classification and solution of aeroelastic problems; Static aeroelasticity; Dynamic aeroelasticity; Unsteady aeroelasticity; Flutter analysis of a wing.
