    • Sail trimming FSI simulation - Comparison of viscous and inviscid flow models to optimise upwind sails trim 
      Communication avec acte
      SACHER, Matthieu; ccHAUVILLE, Frederic; ccBOT, Patrick; DURAND, Mathieu (2015)
      A numerical comparison between two FSI models, based on inviscid and viscous flow solvers, is presented in this paper. The differences between aerodynamic coefficients, sail flying shape and pressures computed by both FSI ...
    • Efficient optimization procedure in non-linear fluid-structure interaction problem: Application to mainsail trimming in upwind conditions 
      Article dans une revue avec comité de lecture
      SACHER, Matthieu; ccHAUVILLE, Frederic; DUVIGNEAU, Régis; LE MAÎTRE, Olivier; AUBIN, Nicolas; DURAND, Mathieu (Elsevier, 2017)
      This paper investigates the use of Gaussian processes to solve sail trimming optimization problems. The Gaussian process, used to model the dependence of the performance with the trimming parameters, is constructed from a ...
    • Numerical study of a flexible sail plan : effect of pitching decomposition and adjustments 
      Communication avec acte
      AUGIER, Benoit; DEPARDAY, Julien; DURAND, Mathieu; ccBOT, Patrick; ccHAUVILLE, Frederic (Ecole Navale, 2013)
      A numerical investigation of the dynamic Fluid Structure Interaction (FSI) of a yacht sail plan submitted to harmonic pitching is presented to analyse the effects of motion simplifications and rigging adjustments on ...
    • Wind-tunnel pressure measurements on model-scale rigid downwind sails 
      Communication avec acte
      ccBOT, Patrick; VIOLA, Ignazio Maria; FLAY, Richard G.J.; BRETT, Jean-Sébastien (Ecole Navale, 2013)
      This paper describes an experiment that was carried out in the Twisted Flow Wind Tunnel at The University of Auckland to measure a detailed set of pressure distributions on a rigid 1/15th scale model of a modern asymmetric ...
    • FSI Investigation on Stability of Downwind Sails with an Automatic Dynamic Trimming 
      Communication avec acte
      DURAND, Mathieu; LOTHODE, Corentin; ccHAUVILLE, Frederic; LEROYER, Alban; VISONNEAU, Michel; FLOCH, Ronan; GUILLAUME, Laurent (Ecole Navale, 2013)
      Gennakers are lightweight and flexible sails, used for downwind sailing configurations. Qualities sought for this kind of sail are propulsive force and dynamic stability. To simulate accurately the flow around such a sail, ...
    • Sensor Fault Detection and Signal Improvement using Predictive Filters 
      Article dans une revue avec comité de lecture
      KERHASCOET, Hugo; MERIEN, P; LAURENT, Johann; SENN, Eric; ccHAUVILLE, Frederic (RINA, 2017)
      Navigation systems used in racing boats require sensors to be more and more sophisticated in order to obtain accurate information in real time. To meet the need for accuracy of the surface speed measurement, the mechanical ...
    • Speedometer Fault Detection and GNSS Fusion using Kalman Filters 
      Communication avec acte
      KERHASCOET, Hugo; LAURENT, Johann; SENN, Eric; ccHAUVILLE, Frederic (2016)
      Navigation systems used in racing boats require sensors to be more and more sophisticated in order to obtain accurate information in real time. To meet the need for accuracy of the surface speed measurement, the mechanical ...
