| Course contents : |
- Action, reaction, propulsion. Historical perspectives and classification of propulsive systems.
- Compressible flows : thermodynamic losses, Fanno and Rayleigh problems, thrust developed by an engine.
- Caracterization of the main components : intakes, compressors, turbines, fans, combustors, nozzles, propellers.
- Jet engines : nominal performances, off-design performances, transients, turbine cooling.
- Rocket engines : performances, nozzle sizing, thermochemistry of the combustion chamber, chemical reactions in the nozzle, selection of the propergols.

|
| Course objective : | The objectives of this course are
- to understand how a propulsion system is conceived according to its mission, to the technological limits and to the operating conditions,
- to understand what influences its peformances and how they can be determined.
|
|
| Prerequisites : | Thermodynamics, Heat Transfers and Fluid Mechanics |
|
| Workshops : |
- Projects are organized by groups of two students. They consist in carrying out a preliminary draft of turbojet that must achieve required performances.
- A laboratory session is organized in order to test a small turbojet, to acquire and to analyse measurements of pressure, temperature, rotational speed, thrust and flow rates.
|
|
| Organization : | This course is organized throughout the second half of the academic year, by 4 hour sessions, at a rate of about 30 hours of theory and 15 hours of exercises. |
|
| Written notes : | Course notes are available, as well as a collection of solved exercises. These notes are regularly updated and are distributed during the course. Reference books are proposed. The slides are in English. |
|
| Assessment : | An oral examination on the theory is organized in June (1st session) and September (2nd session). The project is subject to a report which is also evaluated. |
