Session 2017-18 Level 7 FHEQ First Semester 15

Aims

To build upon the structural analysis methods and aerodynamics covered in the previous three years of the course to enable dynamic analysis of multi-degree-of-freedom systems, beam and plate structures by analytical methods and the finite element method and aeroelastic analysis of multi-degree-of-freedom systems by analytical methods (for advanced aircraft structural component design)


Learning Outcomes

Students will gain new knowledge of aeroelasticity and advanced vibration theory

Students will achieve enhanced understanding of aerodynamics and structural analysis

Students will learn how to solve partial differential equations by analytical and numerical methods


Syllabus

Review of basic vibration concepts: natural frequency, damping, free and forced vibrations, equations of motion, resonance, two-degree-freedom systems, frequencies and modes

Matrix equation of multi-DoF systems. Orthogonality of modes. General solution.
 
Steady aerofoil aerodynamics
Static aeroelasticity: torsional divergence of lifting surfaces and reversal of control surfaces, load distribution
Unsteady aerofoil aerodynamics of Theodorsen
Flutter and its prevention
The Finite Element Method for vibration analysis.
 
Free and Forced Vibration of beams – the Method of Separation of Variables, Eigen-functions. Boundary conditions.
Vibration of plates.

Teaching and Learning Strategies

Lecture - conventional lectures

Tutorial - going through exercises and solutions, and dealing with questions

Practical - guiding students in data centres for computer programming to solve coursework problems

Formative Feedback (e.g. peer, revision sessions) - revision classes
