dc.description.abstract The dynamic Fluid Structure Interaction (FSI) of yacht sails submitted to a harmonic pitching motion is numerically investigated to address both issues of aerodynamic unsteadiness and structural deformation. The model consists in an implicit
dynamic coupling algorithm between a Vortex Lattice Method model for the aerodynamics and a Finite Element Method model for the structure dynamics. It is shown that the dynamic behaviour of a sail plan subject to yacht motion clearly deviates from the quasi-steady theory. The aerodynamic forces oscillation shows hysteresis phenomena and equivalent damping and stiffening effects of the unsteady beahvior.
The area of the hysteresis loop increases with the motion reduced frequency and amplitude.
In the case of a rigid structure, the aerodynamic forces oscillations and the exchanged energy are lower than for a flexible structure.
