Abstract

Revestimiento de cajón de torsión rigidizado con larguerillos no paralelos. Se trata de un cajón de torsión de una superficie sustentadora de una aeronave que comprende un larguero delantero (15), un larguero trasero (17), costillas (21 ) y revestimientos rigidizados superior e inferior, en el que al menos uno de dichos revestimientos (31 ) está rigidizado con una pluralidad de larguerillos (33, 43), preferiblemente larguerillos con forma de omega, que se extienden todos ellos a lo largo de la envergadura completa del revestimiento, preferiblemente en una distribución cónica, y que tienen una sección transversal decreciente hacia el borde exterior del revestimiento.
