To develop an understanding of aeroelastic behaviour of aerospace structures, covering static and dynamic aspects of attached and separated flows.


• Instabilities of non-aerodynamic self-excited systems
• Static aeroelasticity - 3D wings divergence/control reversal.
• Unsteady aerodynamics - Wagner & Theodorsen functions.
• Flutter 3D Wings - binary flutter, solution of flutter equations, frequency matching, control surface flutter, flight flutter testing.
• Prediction of flutter speed from flight test results.
• Non-linear aeroelasticity - stall flutter, buffet, buzz, Limit Cycle Oscillations, affect of structural nonlinearities, aeroservoelasticity, transonic effects, vortex shedding.
• Gusts - simple analysis for discrete gusts and random turbulence
• Kussner and Sears functions.
• Aeroservoelasticity - loads alleviation and flutter suppression.
• Certification and airworthiness issues.

Intended learning outcomes

On successful completion the student should be able to:
1 Perform divergence and control reversal calculations
2 Determine flutter stability boundaries for binary aeroelastic systems
3 Evaluate the response of an aeroelastic system to atmospheric gusts
4 Explain the effect of unsteady aerodynamics and nonlinearities on aeroelastic behaviour

Teaching details

Teaching will be delivered through a combination of synchronous and asynchronous sessions, which may include lectures, practical activities supported by drop-in sessions, problem sheets and self-directed exercises.
