93753 - FUNDAMENTALS OF AERODYNAMICS

Conoscenze e abilità da conseguire

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.

Modalità di verifica e valutazione dell'apprendimento

The exam consists of a single session in which the student should first answer a written test. The test is later discussed with each student and oral questions are proposed about theoretical aspects. The student must show a sufficient skill in writing down and commenting the mathematical models as well as the physical aspects.
