The invention relates to a leading edge mobile flap (16) for a main wing of an aircraft, this flap including an aerodynamic skin (18) that has a bird impact-sensitive frontal area (24), and a rear skin (28) integral with the aerodynamic skin (18), the flap also comprising a plurality...
Influence of a slotted flap gap size on the aerodynamic characteristics of a light aircraft wing at taking off and landing The purpose of the study is to examine the impact of the gap size of 邪 slotted flap on the aerodynamic characteristics of a light aircraft wing at takeoff... IA Angel...
Cruise flaps are trailing-edge flaps that are adjusted to minimize drag by moving the location of the low-drag region of an airfoil drag polar to match the current coefficient of lift. Previous research explored the use of a wing-based pressure-differential ratio called Delta C(p)' to automa...
BL Storms,CS Jang - 《Journal of Aircraft》 被引量: 306发表: 1993年 Computational evaluation of an airfoil with a Gurney flap A 2D numerical investigation was performed to determine the effect of a Gurney flap on a NACA 4412 airfoil. A Gurney flap is a flat plate on the order of 1.....
