A duo propeller disclosed having a forward propeller having increased loading distribution and high swirl near the tip. The duo propeller has an aft propeller with a more optimal loading distribution that can cancel the high tip swirl from the forward propeller. The duo-propeller an enhanced ability for the aft propeller to capture the energy lost to the swirling flow of the forward propeller's outflow.

    L'invention concerne une hélice double comprenant une hélice avant ayant une distribution de charge accrue et un tourbillon intense à proximité de la pointe. L'hélice double comprend une hélice arrière avec une distribution de charge plus optimale qui peut annuler le tourbillon de pointe intense de l'hélice avant. L'hélice double permet d'améliorer la capacité de l'hélice arrière à capturer l'énergie perdue vers le flux tourbillonnant de l'écoulement sortant de l'hélice avant.
