Abstract
L'invention concerne un système de propulsion contrarotatif (CRP), dans lequel l'hélice arrière (22) et l'hélice avant (6) ont des sens de rotation opposés. L'hélice arrière et l'hélice avant sont disposées de manière opposée l'une à l'autre. L'hélice avant est munie d'un cache-moyeu (30) dans lequel au moins deux plaques d'écoulement (28) réparties de manière égale sont montées sur le cache (30) et lesdites plaques d'écoulement (28) font saillie dudit cache (30), dans le sens radial.
