Lectures

Goal

1. Introducing students to the problems and modern methods of calculation and analysis of complex aeroelastic events, and their application in solving practical problems. 2.Introduce students to the methods of experimental investigation of dynamics of aircraft structures. 3.Introducing students to the phenomenon of fluid structure interaction.

Outcome

In the end of successfully completed course Students should be able to: 1. Define aeroelastic phenomena that might occur on the flying structures depending on the flight envelope for which the structure is designed. 2. Set the equations for torsion divergence lifting surfaces, reverse commands and flutter. 3. Solve aeroelastic equations in order to obtain the critical divergence Speed, control reversal speed and the critical speed of flutter.

Theoretical teaching

1. Overview of Aeroelastic phenomena in mechanical, civil and aerospace engineering 2. Static aeroelastic phenomena 3. Dynamic aeroelastic phenomena 4. Section method, torsional divergence of lifting surfaces 5. Flutter, flutter types 6. Numerical methods for static aeroelasticity problems 7. Numerical methods for dynamic aeoelasticity problems 8. Application of La Place transformations in solving aeroelasticity problems

Practical teaching
