AERONAUTICAL PROPULSION SYSTEMS
Course objectives
Knowledge and understanding; At the end of the course the student will be informed about the following topics. - How to get the thrust out of a propeller - How does a turbo-prop work - How does a piston engine work - How to find an optimal design for a general aviation engine Applying knowledge and understanding; Ability to perform a preliminary sizing of the components of an aeronautical propulsion system, and estimate its performance through numerical tools produced by the students themselves during the group work. The training objectives are pursued by using classroom exercises and work in progress reviews. The verification of acquired skills takes place during revisions and course lessons. Making judgements; The skills are acquired through frontal lessons, classroom exercises, and group work. The verification of knowledge is carried out through individual tests and through written group reports, which at the same time ascertain and promote the acquisition of the ability to communicate effectively in written and/or oral form. Communication skills; Ability to work in a team, to present the results of group work with presentations and short technical reports. Learning skills. Expertise to carry out a preliminary design of a general aviation engine powered by either a turboprop or a internal combustion engine. Ability to define a multi-objective design problem. Ability to use ModeFrontier, a robust, multi-objective optimization software.

The course deals with the design and environmental impact of gas turbines combustion chambers for aeronautical applications. Particular attention is devoted to the combustion chamber numerical modelling techniques. The topics covered by the course are listed below.
Chapter 1 Introduction
Chapter 2 Combustion chambers design
Chapter 3 Review of thermodynamics of reacting mixtures
Chapter 4 Aviation fuels
Chapter 5 Fundamentals of turbulent flows and turbulent combustion modelling
Chapter 6 Fundamentals of spray dynamics and spray modelling
Chapter 7 Pollutants and contaminants formation and control
Prerequisites
The knowledge that the student must have at the beginning of the teaching activities, in order to understand their contents and to achieve the learning objectives of the teaching, are the following:
The knowledge of thermodynamic cycles of interest in aeronautical propulsion (Carnot cycle, Brayton-Joule cycle, ideal and real cycles) is indispensable.
Knowledge of the performance parameters of an aeronautical propulsion system (thrust, specific consumption, ...) is indispensable.
It is important to know the basic concepts of thermodynamics and chemistry of organic compounds.
It is useful to have knowledge of the basic concepts of aerodynamics of wing profiles and bluff bodies.
It is useful to know the basic concepts of gasdynamics of compressible flows including the jump relationships for normal and oblique shocks.
