20810303 - Aerodinamica dei velivoli

The aim of the class is to gain knowledge on the overall aerodynamic behaviour of airfoils and wings starting from the fundamental equations governing incompressible and compressible flows and their specialization in the framework of aeronautic applications. To gain knowledge on the main aerodynamic theories used for the design of airfoils and wings and applied to both potential flows and viscous flows with laminar boundary layers. To gain a basic knowledge of the phenomenology of turbulence.

Type of delivery of the course

The course is carried out through traditional lessons given in the room and completed by suited laboratory sessions. Educational material will be rendered available through the web site (including the Moodle platform). During the course, seminars from aerospace industry experts will be given. Visits to aerospace research centers and companies close to the city area, are also planned. The number and location of the visits will be decided during the course along with possible organization constrain.


It is strongly recommended to attend the course in view of the complexity of the treated arguments.

Type of evaluation

Oral examination. The examination dates will be communicated appropriately and published on the web site. Several possibilities will be given to the students to fix the exam starting from the first available date at the beginning of the exam session.
