Abstract

Un système harmonique conçu pour réduire au minimum la traînée de la coque semi-planante d'un navire. Le générateur de vibrations est réglé selon la fréquence fondamentale du navire à la valeur initiale de planage du spectre de la nappe tourbillonnaire. € mesure que la vitesse du navire augmente pour atteindre les vitesses de planage, une vibration sympathique est émise pour faciliter le passage de la région transplanante du navire.
