Modern sailboats are quite sophisticated machines, which use the wind renewable energy to generate propulsion. Such a machines will be studied through the analysis of the involved fluid dynamics principles, starting from lift and drag generation, evaluating the boat equilibrium and the boat performances.
This unit supplies students with the basic fundamentals of the sail aerodynamics and interaction with the hull, as well as technological and application concepts concerning the design methods and materials
The units aims to provide the students with the basic principles of the aerodynamic  hydrodynamic related to the behaviour of sails and hulls. Lift and drag generation are deeply analysed and applied in the sailing boat environment, thus allowing the analysis of the sailing boat balance and performances. Sails (topology and shapes) are then studied in order to characterize their aerodynamic behaviour, highlighting the differences and the common aspects with the 3D airfoils. Keels and rudders are introduced and their effectiveness is analysed as a function of their basic geometrical parameters. Finally, the wave resistance is introduced and consequently the hull shape performances are studied and schemes of velocity prediction program are evaluated.
At the end of course the student shall be able to:
The educational activities are organized into 52 hours of theoretical classes. Practical training activities concerning CFD simulations for sails and hulls and VPP programming may be performed.
Office hours: Student reception is on Tuesday in the professor’s office (Sede di Genova – Villa Cambiaso). Anyway the students are always welcome even if an appointment is suggested.
All class schedules are posted on the EasyAcademy portal.
The exam is basically made through oral discussion of the course topics. Three official examination dates are present during the summer session (June, July and September) and two during winter session (January and February).
Examination is done on a graded scale (130) based on oral discussion of the course topics. Two questions are typically done.
