Basic course in aerodynamics
The course will provide the basis of the aerodynamics of bodies immersed in fluids moving at subsonic speeds, with particular reference to the concepts of boundary layer and velocity potential, with emphasis on the forces and moments acting on the body and provoking its movement.
The course will consist mainly of lectures and applications of the concepts learned in class to the solution of practical aerodynamics problems
- Vorticity Dynamics
Vorticity and circulation; The vorticity equation; Generation of vorticity in incompressible flows
Plane potential flows, Conformal mapping and Joukowsky transformation, Potential flow around a cylinder; Lifting airfoils, Joukowsky airfoils; Potential flow around a two-dimensional body of arbitrary shape;Three-dimensional potential flows; Induced resistance and added mass force
Low speed flow over airfoils: the vortex sheet; The Kutta condition; Kelvin’s circulation theorem and the starting vortex; Symmetric airfoils; Cambered airfoils
The vortex filament, Biot-Savart law and Helmholtz theorems; Prandtl’s classical lifting line theory
Falkner-Skan similarity solution; Hiemenz flow; Boundary layer over an infinite swept wing (FS-Cooke); Preliminary concepts on transition-to-turbulence of the boundary layer.

The course will consist mainly of lectures and applications of the concepts learned in class to the solution of practical aerodynamics problems
The exam will consist of a written test plus an oral examination.
In the course of the semester, the students must take two partial exams, for the instructor to monitor their level of comprehension of the topics covered. Furthermore, to ascertain their maturity, critical thinking and capacity of synthesis, the writing of a term paper is required, on a topic chosen by the student and inherent to aerodynamics. The paper is then presented by each student to the whole class.
