Aeroelastic Wind Tunnel Testing and Aeroelasticity Considerations for Non-Aeroelastic Tests

In This Section

Synopsis:

This course is specific to aeroelasticity concerns and wind tunnel testing. The greater emphasis will be on the testing of aeroelastic models; however, some attention will be given to aeroelasticity considerations for non-aeroelastic tests. Some historical perspective on aeroelasticity will be provided including coverage of the discipline field and specifically wind tunnel testing. Major aspects of wind tunnel testing particularly pertinent to aeroelasticity will be covered. Testing techniques specific to various types of aeroelastic phenomena will be introduced. In the hopes of conveying realistic applications, a number of case-study-type reviews encompassing several aeroelastic behaviors, various configuration types, and diverse project objectives will be presented. The planned course material will be predominately basic material appropriate to practical application without great depth from a theoretical or academic perspective, though higher-level methodologies will be identified and references provided.

Key Topics:

  • To provide a historical overview on wind tunnel testing for aeroelasticity
  • To provide a basic understanding of aeroelastic phenomena
  • To convey key considerations for aeroelastic model design, fabrication and testing
  • To inform students regarding critical aspects of aeroelastic wind tunnel testing
  • To build an awareness of aeroelasticity concerns of potential impact for non-aeroelastic tests

Who Should Attend:

This course is formulated for individuals with limited knowledge of aeroelasticity having an interest or need to understand the discipline, particularly with respect to the potential of formulating or supporting aeroelastic wind tunnel tests, and also those wishing to understand aeroelastic influences or concerns for non-aeroelastic tests.

General Course Information:

  • Type of Course: Instructor-Led Short Course
  • Course Level: Intermediate
  • Course Length: 1 day
  • AIAA CEU's available: yes
