Aeroservoelasticity Laboratory

AE 255: Aeroelasticity

Aeroelasticity is the study of the interactions between the elastodynamics of aflexible lifting surface with the dynamics of the fluid flow over it. The issues that are of concern in this study include stability of the aeroelastic system, its static and dynamic response, and controlling these aeroelastic instabilities and response.

Prerequisites: Senior undergraduate level or graduate level course in vibration (preferably AE 264) and aerody-namics/fluid dynamics is necessary to credit this course.

Semesters Taught: Odd semesters

AE 264: Vibrations

Vibrations are ubiquitous in nature. They range from two-and-fro motion of the branches of a tree under the influence of winds to motion of the suspension of a motor vehicle.

Prerequisite: Calculus, basic mechanics, basics of linear algebra.

Semesters Taught: Even semesters.

AE 291: Special topics in aerospace engineering

The topics covered in this course would be drawn from the research activities conducted in the Aeroservoelasticity. Various numerical tools and frameworks pertaining to fluid-structure interactions would be discussed with special focus on the individual research interests of the course participants.

Prerequisite: Calculus, basic mechanics, basics of linear algebra.

Semesters Taught: Odd semesters
