Program Sail2D
A further module in
the workflow would be the simulation of the rig. This
work is in progress. Classical
wing theory can be used to calculate the forces acting on the sails.
The theory relies on the input of the aerodynamic characteristics of
the 2D sail sections. The program XFOIL was used to create a database
of discrete values of the required coefficients. The theoretical
background is described in this report. Sail2D is a program that
interpolates in the database and provides the coefficients at arbitrary
independent variables.
Details of the program are explained in the user's manual that can be downloaded here:
