Abstract

This final work proposes to analyze different hydrodynamic solutions for an America’s Cup Class sailing boat keel.

After a brief history of America’s Cup, through the main technological innovations that have been followed along the different editions, Chapter 1 introduces the aim of this final work: the fluid dynamic analysis of two alternative keels for IACC boats.

The physical principles that drive the motion of a sailing boat are reported in Chapter 2.

Chapter 3 analyzes America’s Cup Class Rule, governing the XXXII edition, paying attention to all that limitations that regulate the dimensions of the under water part of the yacht.

The geometrical features of the configurations taken in exam, together with criterions used for their dimensioning, are shown in Chapter 4.

Chapter 5 presents the preliminary 3-D fluid dynamic analysis, aiming to determine the lifting properties of different keels, and the 2-D parameters’ sensitivity analysis.

Chapter 6 reports the 3-D fluid dynamic analysis of full appended configurations.

Chapter 7 analyzes the behaviours of the two proposed solutions and possible future developments.

Appendix I shows the detailed realization of 3-D parametrical models used in this work.

Appendix II reports the different phases of CFD analysis, performed with Fluent

software, together with its settings.

Appendix III presents the capabilities of Xfoil software, employed for 2-D parameters’

sensitivity analysis.
