Course contents :
|
| Turbomachinery Rotordynamics : Types of Modelling, Computation of Forward and Backward Critical Speeds, Campbell Diagram, Stability Analysis, Harmonic and Transient Responses, Multi-rotor Mehavior, Design of bearings, Instability Phenomena. Dynamics of Blades and Disks : Campbell Diagram, External Excitation Sources, Aeroelastic Problems, Bird Impact. Static Analysis of Compressor Blades : Compensation, Effect of Pre-Twist, Flexure/Torsion Coupling. Static Analysis of Disks : Design Criteria. Lifetime Calculations of Turbine Blades. |
|
Learning outcomes of the course :
|
| The objective is to present the methods used in the aeronautical industry to analyze the dynamical behavior of turbomachines and to design mechanical components of turbojet engines such as compressor and turbine blades and disks. |
|
Prerequisites and co-requisites/ Recommended optional programme components :
|
| This course requires basic knowledge in structural dynamics and of the finite element method. |
|
Planned learning activities and teaching methods :
|
| Projects will be assigned to the students. It will give hands-on practice with methods used for the mechanical design of turbomachines. |
|
Mode of delivery (face-to-face ; distance-learning) :
|
| The course is organised face-to-face during the 1st quadrimester. |
|
Assessment methods and criteria :
|
| The final grade will be based on the project reports and the oral exam:
1. Group of students will be assigned a project. The grade will be based on the results and the quality of the report (scientific and technical content, conciseness, structuring of the written report and clarity of the text).
2. The oral exam will be based on the individual presentation of the project reports. During the oral exam, the students will have to show a solid knowledge of the course materials. A special attention will be devoted to the understanding of the different concepts.
Student assessment criteria:
- Project reports: 50%.
- Oral exam: 50%.
September exams: same terms, but, if the grade of the project reports is below 12/20, the student will be assigned a new project. |
|
Organizational remarks :
|
| The course will start on Tuesday 20 September 2011 at 14:00 in rom 0/523 (B52). |
