The invention discloses a miniature unmanned aerial vehicle using bionic chordwise corrugated wings. The miniature unmanned aerial vehicle comprises the corrugated wings, a power system, a fuselage and a pneumatic control surface, wherein the corrugated wing is a fixed rectangular wing, the distance between the corrugated part and the front edge is 10% c (c is the chord length of the wing), the height of the corrugated part is 6% c, the length of the corrugated part is 10% c, and a simplified model wind tunnel experiment proves that the corrugated structure has the best effects of delaying stall and inhibiting self-induced rolling oscillation. According to the technical scheme, the flow separation phenomenon under the large attack angle can be effectively controlled, the structure is simple, the control capacity is maximized within the designed attack angle range, and the harmful effect is minimized within the non-designed attack angle range.
本发明公开了一种使用仿生弦向波纹机翼的微型无人机,包括:波纹机翼、动力系统、机身和气动舵面;其中,波纹机翼为固定矩形翼,波纹部分距前缘距离为10%c(c为机翼弦长),波纹部分高度为6%c,波纹部分长度为10%c,经简化模型风洞实验证明,此种波纹结构对于延迟失速,抑制自诱导滚转振荡效果最佳。本发明的技术方案,能够有效控制在大迎角下的流动分离现象,且结构简单,在设计迎角范围内使操控能力最大化,在非设计迎角范围内有害影响最小化。
