      De par sa discrétion, la détection passive est un atout majeur pour la surveillance de zones maritimes, notamment dans le cas de détection de plongeurs intrus dans les zones portuaires. Des outils de traitement du signal ...
    • SACHER, Matthieu; HAUVILLE, Frédéric; DUVIGNEAU, Régis; LE MAITRE, Olivier; AUBIN, Nicolas; DURAND, Mathieu (2016)
      This paper investigates the use of meta-models for optimizing sails trimming. A Gaussian process is used to robustly approximate the dependence of the performance with the trimming parameters to be optimized. The Gaussian ...
    • HAUVILLE, Frédéric; LECUYER-LE BRIS, Romain; DENISET, François; FASSE, Guillaume (2018)
      Les propulseurs cycloïdaux sont caractérisés par la rotation de plusieurs pales autour d’un axe vertical, associée à un mouvement de chaque pale autour de son axe propre. L’objet de cet article concerne l’étude des lois ...
    • DEPARDAY, Julien; BOT, Patrick; HAUVILLE, Frédéric; AUGIER, Benoit; RABAUD, Marc; MOTTA, Dario; LE PELLEY, David (2016)
      While sailing offwind, the trimmer typically adjusts the downwind sail "on the verge of luffing", letting occasionally the luff of the sail flapping. Due to the unsteadiness of the spinnaker itself, maintaining the luff ...

      An experiment was performed in the Yacht Research Unit’s Twisted Flow Wind Tunnel (University of Auckland) to test the effect of dynamic trimming on three IMOCA 60 inspired mainsail models in an upwind (AWA = 60 ) unheeled ...
    • SACHER, Matthieu; HAUVILLE, Frédéric; BOT, 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 ...
    • BOUFFAUT, Léa; DREO, Richard; LABAT, Valérie; BOUDRAA, Abdel; BARRUOL, Guilhem (2017)
      More than 30 years after the institution of the moratorium on commercial whaling by the International Whaling Commission, one of the biggest challenges in whale monitoring, e.g. Antarctic Blue Whales (ABW), is assessing ...
