Syllabus
Prerequisites: Kinematics and statics of rigid bodies, statics of rigid bodies, virtual work principle, kinematics and statics of deformable bodies, linear elasticity, solution of both statically determinate and un-determinate structures, force and displacement methods, virtual work theorem. De Saint Venant's problem, failure criteria, equilibrium stability. Advanced topics in structural mechanics, in particular beams with thin walled cross sections and plates. The finite element method. Fundamental knowledge and methods for the analysis of aerodynamics flows in the inviscid compressible and viscous incompressible regimes.
Target skills and knowledge: Fundamental knowledge of theories and methods for the analysis of aeroelasticity problems both static and dynamic.
Design criteria, experimental and computational techniques for the evaluation of aeroelastic loads for aeronautical applications.
Examination methods: The written exam tests both the capability to solve two structural problems and to answer two theoretical questions. The two exercises assess the student's capabilities to solve aeroelasticity problems. The theory questions assess her/his understanding of the theoretical foundations. An oral exam may follow the written exam if the student wants to improve her/his mark.
Exercises and theory questions are assessed separately. Students have to obtain at least 18/30 in both parts of the written exam to pass the exam. The theory question mark, weight 1/2, is added to the exercise mark, weight 1/2, to form the written exam mark.
• If the written exam mark is between 18 and 27 it will usually be the final exam mark
• If the written exam mark is above 27 the student is invited to sustain an oral exam to confirm (increase or decrease) the mark. If the student sustains the oral exam that will determine the final exam mark, otherwise the final exam mark will be 27.
• In the case of written exam mark below 18, or of failure at the oral exam, the student will have to take again the written exam.
Assessment criteria: The pass mark is awarded to students who have a correct approach to problem solving and theory. Full marks are given to students who solve perfectly all paper exercises and answer correctly all theory questions.
Course unit contents: Definition and classification of aeroelasticity phenomena. Background concepts on vibration of single and multiple degree of freedom systems and continuous systems. Structural response of a mechanical system with a random input load. Fundamental strategies for the aerodynamic analysis (panels method, vortex method, piston theory). Control techniques and stability of systems. Static aeroelasticity, effect of wing flexibility on lift distribution, 2 DoF model, study of the divergence. Aeroelasticity with unsteady aerodynamics. Dynamic aeroelasticity, flutter phenomena and stability limits evaluation. Gust and turbulence effects. Fundamentals of aircraft design and certification with reference to the aeroelasticity phenomena.
Planned learning activities and teaching methods: Learning is based on attending the lectures and on the subsequent study of the relevant books. Teaching is traditional. Many examples are completely worked out in class.
Practice sessions with computational software (Patran-Nastran) to study aeroelasticity problems are planned.
Additional notes about suggested reading: Besides the textbook, lecture notes will be provided by the lecturer using the moodle platform.
