Objectives
This lecture has several objectives:
- to get deeper into the details concerning the notions of aero-energetics in the frame of open systems with compressible flows, which are essential for the understanding and the study of the performance of turbojet engines.
- to list and sort the different propulsion systems for aeronautics (turbojet, turbofan, turboprop...) with the associated aircraft.
- to learn how to calculate the performance of turbojet engines, for a prescribed operating point, and to know how to simply design a propulsion system.

Programme
- Aero-thermodynamics of the steady quasi-monodimensional flows (quantification and effects of the exchanges of work, heat and viscous shear layers)
- Complements of aero-thermodynamics for open systems with compressible flows
- Characterisation of compressors and turbines (exchanged energy, efficiency, performance map, mechanical behaviour, vibrations and material)
- Aero-mechanical characterisation of the other components (combustor, nozzle, ...)
- Performance analysis of the turbojet engines
- First approach and tools for the design of turbojet engines
Learning Outcomes
- To understand the operating of the parts of turbojet engines (fan, compressor, combustor, turbine, nozzle,...)
- To understand and analyse the thermodynamic cycle of turbojet engines
- To be able to calculate the performance of turbojet engines (thrust, efficiency, consumption, ...)
- To be aware of the new concepts that will drive the design of the new turbojet engines.
