Abstract
Un aspa de ventilador (134) incluye una región de trabajo (148) que tiene un borde de ataque (138) y un lado de presión (136). Una pluralidad de características de modificación de flujo (150-1 a 150-4) están situadas en la región de trabajo, incluyendo una primera y una segunda característica de modificación de flujo (150-1, 150-2, 150-3), teniendo cada una de las cuales una forma de cuña con un extremo puntiagudo (152) y un extremo más ancho (154) situadas en el lado de presión. Una longitud de la primera característica de modificación de flujo es menor que una longitud de cuerda del aspa de ventilador, y el extremo puntiagudo de la primera característica de modificación de flujo está separado del borde de ataque. Una longitud de la segunda característica de modificación de flujo es menor que la longitud de cuerda del aspa de ventilador, y el extremo puntiagudo de la segunda característica de modificación de flujo está separado del borde de ataque. La primera y segunda características de modificación de flujo están separadas entre sí para definir un canal (156) entre ellas.
