Aeroelasticity
Aero-45910
Instructor:

Description:
This course will address issues related to the
mutual interaction of elastic, inertial, and aerodynamic forces with emphasis
on aeronautical applications.
Course Objectives:
This course is a collection of special topics in
the application of solid and fluid interaction in aerospace area, which is
called aeroelasticity. It quantifies the effects of the inertial, structural
and aerodynamic parameters that affect divergence, control surface reversal and
flutter and calculation of critical speeds for these phenomena for
simple wings using steady, and in the case of flutter, unsteady aerodynamic
assumptions.
Prerequisites by Topic:
- An understanding of
aerodynamics (or Fluid Mechanics).
- An understanding of
structural dynamics (or Vibrations).
