lecture notes

1) The aim is to give the elements for the performance prediction of aero-engines and rocket engines.
2)
cc1: In-depth knowledge and understanding of the theoretical-scientific aspects of engineering, with a specific reference to mechanical engineering, in which students are able to identify, formulate and solve, even in an innovative way, complex and/or interdisciplinary problems. The ability to understand a multidisciplinary context in the engineering field and to work with a problem solving approach.
cc3: Knowledge, understanding and use of scientific (computer and other) tools specific to the field of mechanical engineering design.
cc11: Knowledge and understanding of the machinery sector deepening the aspects properly connected with systems for energy production and transformation, with reference also to renewable energies and/or aspects related to propulsion systems. Understanding the role of different energy technologies in ensuring the environmental and economic sustainability of production.
3)
ca3: Applying knowledge and understanding related to the choice and application of appropriate analytical and modelling methods, based on mathematical and numerical analysis, in order to better simulate the behavior of components and plants in order to predict and improve their performance.
ca6: Applying knowledge and understanding related to the identification, location and retrieval of data and information necessary for the assessment.
ca8: Applying knowledge and understanding related to the appropriate interpretation of the results of experimental tests, verification calculations and complex theoretical simulation processes, through the use of the computer, applying the acquired experimental, modeling, mathematical and informatics bases.
ca9: Applying knowledge and understanding related to the critically assessment of data and results, drawing appropriate conclusions, aware of the degree of uncertainty that may affect them.
ca12: Applying adequate knowledge and understanding to understand English texts.
ca15: Applying knowledge and understanding to achieve adequate preparation for tertiary level university studies (frequency to post-master's degree courses and doctoral schools) in order to further deepen knowledge and skills in research.
