Aeroelastic analysis of a yacht rig
Aeroelastic analysis of a yacht rig
An aeroelastic solution for a mast sail system has been achieved and has been shown to predict realistic behaviour of the system. A nonlinear finite element analysis computer program has been developed, incorporating membrane and solid elements. This has been coupled with a potential flow panel code, PALISUPAN, developed in the University of Southampton, to achieve the aeroelastic solution using a velocity stepping procedure.
A mast sail rig has been analysed in an upwind configuration. The results of the analysis demonstrate the influence of the coupled nature of the mast and sail on the calculated sail forces and deformed shape. Mast compression predicted by the aeroelastic solution of the mast sail system was compared to compression calculated by distributing the sail forces on a nonlinear model of the mast. Results indicate that previous loading assumptions for finite element analysis of a mast significantly underestimate mast compression due to sail loading.

Abstract
An aeroelastic solution for a mast sail system has been achieved and has been shown to predict realistic behaviour of the system. A nonlinear finite element analysis computer program has been developed, incorporating membrane and solid elements. This has been coupled with a potential flow panel code, PALISUPAN, developed in the University of Southampton, to achieve the aeroelastic solution using a velocity stepping procedure.
A mast sail rig has been analysed in an upwind configuration. The results of the analysis demonstrate the influence of the coupled nature of the mast and sail on the calculated sail forces and deformed shape. Mast compression predicted by the aeroelastic solution of the mast sail system was compared to compression calculated by distributing the sail forces on a nonlinear model of the mast. Results indicate that previous loading assumptions for finite element analysis of a mast significantly underestimate mast compression due to sail loading.
