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. |
|
Recommended or required readings :
|
| |
|
Assessment methods and criteria :
|
| The final grade will be based on the project report and the oral exam:
1. 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). An oral presentation will be organised at the end of the project.
2. The oral exam will consist in answering to questions on the course materials. A special attention will be devoted to the knowledge and to the understanding of the theoretical concepts.
The final assessment is based on the weighted geometric average of the project reports and the oral exam. The final note is calculated as follows:
Final note = (Project)^(0.75) * (Oral exam)^(0.25) |
