supercavitant

OBS: cavitation: Phénomène qui se produit lorsqu'une hélice tourne trop vite: l'air contenu dans l'eau forme une cavité gazeuse autour des pales de l'hélice qui tourne alors dans le vide.

CONT: supercavitating propeller: (...) A marine propeller which has special blade sections so that at sufficiently high speed the whole back of each blade becomes enveloped by a smooth sheet of cavitation.
OBS: supercavitation: (...) cavitation leaving the trailing face of a propeller blade free of water.
OBS: cavitation: Disturbance around revolving propeller blades struts, etc., caused by collapse of transient pressure disturbances resulting from flow of water over their surfaces.
