Hi everyone!

Welcome to the course Introduction to Aerodynamics!

I’m Bartomeu Pericas, and I will be the instructor for this course.

I’m an aerospace engineer. I studied aerospace engineering at the Polytechnic University of Catalonia and worked for a short time in the aviation industry. Then, I decided to follow my passion, and I went to study yacht design.

Since then, I have worked in the yachting industry for both motor yachts and sailboats, first in the Netherlands and now in Spain, where I’m currently working for a refit company for sailboats.

So, what is this course going to be about?

We will study the fundamentals of aerodynamics to understand sail and wing performance.

Why do I say wing? Because almost all the theory in aerodynamics has been developed for wing performance.

Firstly, we will see the aerodynamic variables, airfoil, and wing geometry to understand all the theorems that, further on, we will use for the analysis of 2D and 3D bodies, that’s to say, airfoils and wings.

And then, we will finish the course with a sum-up to apply everything to sail performance.

Thank you!

I hope to see you on the course!
