Abstract

Se describe un aparato de excavación (5), tal como un aparato de excavación subacuática, que tiene medios para producir, durante el uso, al menos un vórtice, espiral o flujo turbulento en un flujo de fluido laminar, por ejemplo, agua. El aparato de excavación (5) comprende un rotor (10) que tiene un eje de rotación del rotor (A), en el que, durante el uso, el flujo de fluido que pasa o atraviesa el rotor (10) forma un primer ángulo (a) desde el eje de rotación (A). El aparato de excavación (5) comprende el rotor (5) y un medio o una disposición para atenuar el par motor reactivo en el aparato (5) causado por la rotación del rotor (10), durante el uso. El flujo turbulento se provee dentro, tal como dentro de una sección transversal del flujo laminar.
