Abstract

Dispositivo para hacer visible la dirección de un flujo de fluido sobre una superficie de un objeto, que comprende un elemento similar a una aleta que está unido de una manera articulada a dicha superficie y que está localizado más próximo o más alejado de dicha superficie dependiendo de dicho flujo, donde la superficie de al menos un lado de dicha aleta y esa parte de la superficie de dicho objeto que está localizada sobre un lado de la línea de articulación están construidas de tal forma que cuando dicha parte de la superficie está cubierta ópticamente por dicha aleta se obtiene una apariencia óptica que se diferencia de la apariencia óptica en el caso donde dicha parte de la superficie no está cubierta ópticamente, caracterizado porque dicho elemento similar a una aleta comprende una pluralidad de aletas, estando dispuesta cada una para moverse completamente desde una posición a otra sin que se produzca torsión sobre la anchura de la aleta.
