摘要
在本文中,我们研究的影响小翼脚趾和扭转角的翼飞机的空气动力学性能,如何提高我们分析机翼的空气动力特性与斜面角度60 o和小翼机翼跨度= 3.5米,我们测试的翅膀与不同的脚趾角度(+ 10 o, o + 5 0啊,5 o,和-10 o)和扭曲的角度(0 + 5 o, o, o + 5)和所有模型测试四攻角AOA(6 0啊,3 o, o,和9 o)。然后计算L/D值，以确定哪个机翼具有高升力和低阻力值。使用SOLIDWORKS程序绘制机翼的所有模型(60个模型)，其中我们使用波音737-800机翼尺寸。然后利用ANSYS FLUENT对某型机翼的各模型进行了分析。
Using the Winglet Toe and Twist Angle to Improve Wing Aerodynamics Performance
In this paper, we study the effect of winglet Toe & Twist angle on the wing of the aircraft aerodynamics performances and how to improve it, we analyze the aerodynamics properties of the wing with winglets with Cant angle 60o and winglet span = 3.5 m, we test wings with different toe angles (+10o, +5o, 0o, -5o, and -10o) and twisted angles (+5o, 0o, and +5o) and all model are tested for four Angle of attack AOA (0o, 3o, 6o, and 9o). Then calculate the value of L/D to decide which wing has a high value of lift and lower drag. All models of a wing (sixty models) are drawn for 3D using the SOLIDWORKS program where we used Boeing 737-800 wing dimensions. Then all models of a wing were analyzed using ANSYS FLUENT.
