Abstract

Un conjunto de superficie de sustentación (300; 400; 500; 600; 700; 800) que comprende: una primera superficie (314) superior y una segunda superficie (316) inferior, un dispositivo de borde de ataque (302) acoplado de manera articulada a la primera y segunda superficie (314, 316) a través de una bisagra (310) y que comprende un borde de ataque (304) y un borde de salida (306), una superficie aerodinámica (334) que soporta el dispositivo de borde de ataque (302) y configurado para actuar como una extensión del borde de salida (306) cuando el dispositivo de borde de ataque (302) está bajado, cubriendo de este modo una distancia (338) entre el borde de salida (306) y un borde (340) de la primera superficie (314), en el que el borde de salida (306) y el borde (340) se solapan cuando el dispositivo de borde de ataque (302) está en una posición completamente retraída o nominal y al menos un generador de vórtice (308) retráctil acoplado a la primera y segunda superficie (314, 316) por debajo del borde (304), y operable para: extenderse fuera de una ranura (322) en un revestimiento y una distancia por encima de la superficie aerodinámica (334) para aumentar la sustentación, cuando el dispositivo de borde de ataque (302) articulado está bajado; y retraerse dentro del conjunto de superficie de sustentación (300; 400; 500; 600; 700; 800) para reducir el arrastre, cuando se levanta el borde de ataque (302) articulado.
