Organisation and examination

Teaching in the second semester

Units courses prerequisite and corequisite

Prerequisite or corequisite units are presented within each program

Learning unit 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.

Learning outcomes of the learning unit

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.

Prerequisite knowledge and skills

Thermodynamics, Heat Transfers and Fluid Mechanics

Planned learning activities and teaching methods

• 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.

Mode of delivery (face-to-face ; distance-learning)

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.

Recommended or required readings

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 methods and criteria

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.
