Learning outcomes

At the end of the module, by applying acquired in the courses of basic physics and fluid mechanics, the student will be able to describe the main physical mechanisms underlying the generation of lift and drag on the aircraft or on its individual components. Mathematical models will be introduced to carry out numerically, where this is possible, an initial estimate of these force components.

Assessment methods

The exam consists of a single oral session. To pass the exam, the student must demonstrate sufficient knowledge of all the fundamental aspects underlieng the mechanism of generation of lift and drag, of the mathematical models to make quantitative predictions and of the main engineering results presented in the course.

To a positive evaluation will contribute the clarity of explanation as well as the ability of making connections between the mathematical models and the underlying physical and engineering aspects of the subjects covered.
