本文介绍了一种采用波纹结构的变几何变形翼型的研制和风洞试验。通过有限元分析验证了波纹柔性无缝襟翼式结构变形机翼的概念验证研究，并采用碳纤维增强塑料制造了原型。在作动系统中，两个伺服电机安装在原型机翼内，通过连接的电线的弦向张力来控制翼型形状。在风洞试验中，原型机翼在空气速度高达30 m/s的情况下成功驱动。基本的空气动力特性也进行了评估，与传统的翼型与铰链控制面。变波纹机翼的升力随着副翼转角的增大而增大。
This paper describes the development and the wind tunnel test of a variable geometry morphing airfoil using corrugated structures. Proof-of-concept study of a morphing wing with corrugated flexible seamless flap-like structure is verified by finite element analysis, and a prototype is manufactured using carbon fiber reinforced plastics. For the actuation system, two servomotors are installed inside the prototype wing to control the airfoil shape by the chordwise tension of the connected wires. Successful actuation of the prototype wing is demonstrated under the air speed up to 30 m/s in the wind tunnel test. Basic aerodynamic properties are also evaluated in comparison to traditional airfoil with a hinged control surface. Lift increase of variable corrugated wing is recognized compared to the traditional wing when the aileron angle increases.
