Title: Re: 787 Dreamliner wing test Post by: allthatido on March 31, 2010, 07:15:21 PM i think they are giving it the required dihedral ?????????????????? its more of a shear stress test for the wing. See how much it can bear before it gives away. Title: Re: 787 Dreamliner wing test Post by: Pikle6 on March 31, 2010, 10:20:13 PM exactly this is a stress test for the wings. if you look out of the window of a airliner while landing you will surely notice the flex in the wings during final descent. this flexibility is more or less necessary for a passenger jet as they travel quite fast also that is the reason training aircraft wings like cessna 182's doesnot have lot of flex as they can approach at comparatively slow speeds.
