To develop an understanding of aeroelastic behaviour of aerospace structures, covering static and dynamic aspects of attached and separated flows.
Content:
• 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.
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 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.
100% portfolio
If this unit has a Resource List, you will normally find a link to it in the Blackboard area for the unit. Sometimes there will be a separate link for each weekly topic.
If you are unable to access a list through Blackboard, you can also find it via the Resource Lists homepage. Search for the list by the unit name or code (e.g. AENGM0069).
How much time the unit requires
Each credit equates to 10 hours of total student input. For example a 20 credit unit will take you 200 hours
of study to complete. Your total learning time is made up of contact time, directed learning tasks,
independent learning and assessment activity.
See the Faculty workload statement relating to this unit for more information.
Assessment
The Board of Examiners will consider all cases where students have failed or not completed the assessments required for credit.
The Board considers each student's outcomes across all the units which contribute to each year's programme of study. If you have self-certificated your absence from an
assessment, you will normally be required to complete it the next time it runs (this is usually in the next assessment period).
The Board of Examiners will take into account any extenuating circumstances and operates
within the Regulations and Code of Practice for Taught Programmes.
