Organisation and examination
Teaching in the first semester, review in January
Schedule
Units courses prerequisite and corequisite
Prerequisite or corequisite units are presented within each program
Learning unit contents
Turbomachinery Rotordynamics : Types of Modelling, Computation of Forward and Backward Critical Speeds, Campbell Diagram, Stability Analysis, Harmonic and Transient Responses, Multi-rotor behavior, Design of bearings, Instability Phenomena. Dynamics of Blades and Disks : Campbell Diagram, External Excitation Sources, Aeroelastic Problems, Bird Impact. Static Analysis of Compressor Blades : Leaning, Effect of Pre-Twist, Bending/Torsion Coupling. Static Analysis of Disks : Design Criteria. Lifetime Calculations of Turbine Blades.
Learning outcomes of the learning unit
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.
Prerequisite knowledge and skills
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 written exam and the homeworks. The written 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. No document is allowed for the examination.
