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 |
