CCR

The CCR: from concept to realisation

This is useless to find an aerodynamic optimized configuration if it's unrealisable on a structural mechanical point of vue.

Let's take the example of a foil: If you only look at some aerodynamic considerations, the foil should thicker as possible. But during a run, forces generate some huge momentum. The structure must be able to accept it, so the foil must have a minimum thickness.

Result: We have two antagonistic criterions !!!

To solve this problem, we are making a "numerical chain" which is composed by the following:

Using a finite-element code (CASTEM 2000) with an automatic mesh generation and a usefull post-processing in order to make parametric studies.
Quickly test new boat's configurations by calculating the boat's structural response to the aerodynamic and hydrodynamic forces.
