Aeroelasticity State-of-the-Art Practices

In This Section

Synopsis:

In recent years there has been a renewed interest in aeroelasticity arising from high performance aerospace systems, multiple control surface configurations, and pathologies associated with nonlinear behavior. This course provides a brief overview of aeroelasticity and examines many new "fronts" currently being pursued in aeroelasticity that include reduced-order models, integrated fluid-structural dynamic models, ground vibration testing, wind tunnel tests, robust flutter identification approaches for wind tunnel and flight test programs, aeroservoelasticity, and aeroelasticity of very flexible aircraft. The course will emphasize current practices in both analytical and experimental approaches within industry and government labs, as well as advances as pursued by these organizations with the support of university research.

Key Topics:

  • Background
  • Ground Testing
  • Analysis
  • Aeroservoelasticity
  • Flight Tests
  • Special Topics

Who Should Attend:

People who attend this course are those who wish to learn the principles of aeroelasticity, acquire an understanding of new approaches in aeroelastic theory and analysis, gain an understanding of state-of-the-art practices in ground-based and flight tests, gain insight into non-classical aeroelastic phenomena, and methods in computational aeroelasticity.
