Abstract

Un conjunto de ala de avión que incluye una parte (10) de ala principal y una parte (12) de gran sustentación de borde de ataque,movible entre una posición retraída en la que, generalmente, se funde con la parte de ala principal y una posición desplegada, por delante de la misma, caracterizado porque al menos una parte sustancial de una superficie superior (22) de dicha parte de gran sustentación es permeable al aire o está perforada y en comunicación de flujo con un paso de succión (30) asociado con dicha parte de gran sustentación, por lo que en vuelo, puede aplicarse succión a dicho paso de succión para, al menos, reducir la extensión en el sentido de la cuerda de la capa límite turbulenta, en al menos, una de las superficies, superior e inferior, del ala.
