Connaissances
At the end of the course, the student will be able to explain:
- The phenomenological origin of the different aeroelastic phenomena studied (divergence, flutter, aileron reversal, etc.)
- The influence of the design parameters on the occurence and severity of these phenomena
- The fundamental principles of steady, quasi-steady and unsteady aerodynamics
- The physical interpretation of the aeroelastic system equations, and the different parameters present in these equations (typically, the aeroelastic stiffness)
- The concept of Vortex Induced Vibrations (VIV) and Limit Cycle Oscillations (LCO)
- The basic principles of practical aeroelastic testing
Aptitudes
At the end of the course, the student will be able to:
- Derive the equations of motion of a full aeroelastic system
- Compute the divergence, flutter and reversal speeds
- Write a code solving a dynamic aeroelasticity problem
Compétences
At the end of the course, the student will be able to:
- Use the tools and theory of static and dynamic aeroelasticity in the context of airplane design
1) Introduction: introduction to aeroelastic phenomena, which may seem counter-intuitive, and sensitization to the importance of aeroelasticity for good airplane design
2) Static aeroelasticity: equations of motion of the aeroelastic system, and starting from these, inferring the different static phenomena such as wing divergence
3) Dynamic aeroelasticity: introduction to quasi-steady and unsteady aerodynamics, and study of dynamic aeroelastic systems, with as main objective the study of flutter
4) Practical aeroelasticity: fundamentals of aeroelastic testing
5) Vortex Induced Vibrations and Limit Cycle Oscillations: if time allows
One course session is also devoted to a computer laboratory, devoted to dynamic aeroelasticity. A personal report on this laboratory session should be handed in
