Abstract

Le ski parabolique d'une motoneige est un corps allongé avec deux bords tranchants, opposés et symétriques, situés le long de la face inférieure et d'une quille. La quille est fixée à la face inférieure du ski et comporte une arête médiane centrale, c'est-à-dire une tranche. Une partie importante de la tranche fait saillie sous la face inférieure du ski pour former un point de contact central et longitudinal avec la neige. La quille définit des rainures symétriques qui canalisent la neige et qui sont situées le long des côtés opposés de l'arête médiane centrale. Les rayons de courbure variables des rainures forment les parois latérales extérieures paraboliques des canaux. Les bords tranchants de la quille, opposés, symétriques et de forme parabolique, sont formés par le profilage de la largeur du corps de quille. Ce profilage suit le contour des parois latérales extérieures paraboliques de façon à donner une largeur constante aux bords tranchants.
