The invention discloses a miniature unmanned aerial vehicle adopting a bionic separation flow wing type. Wings are included. A section of each wing adopts a bionic separation flow wing type; the wholeshape of each wing is a cuboid-shaped plate; an upper side of a front edge of each wing is sharpened; and a sharpening angle is an acute angle, an arc flap is further arranged on the rear portion ofeach wing, a supporting rod which penetrates through the wings and is perpendicular to the wings is included, an electric propulsion mechanism is further arranged on the head portion of each wing andfixed to the supporting rod, a tail end of the supporting rod is further connected with a horizontal tail, and the tail end of the supporting rod is further connected with a vertical tail which is vertically upward. According to the separation flow wing type, a fluid is separated at a front edge sharpening point, then airflow is rapidly transited into a turbulent flow, the turbulent flow can better resist the turbulent flow in the atmosphere, the separation airflow can be attached to the surface of the arc flap again to form a stable low-pressure vortex area, a considerable lift force is brought, and an airplane obtains good aerodynamic characteristics and flight stability.
本发明公开了一种采用仿生分离流翼型的微型无人机,包括机翼,机翼的剖面采用仿生分离流翼型,机翼的整体形状为长方体型板,机翼的前缘上侧被削尖,削尖尖角为锐角,机翼的后部还设置有圆弧襟翼,还包括穿过机翼且与机翼垂直设置的支撑杆,机翼的头部还设置有电动推进机构,电动推进机构固定在所述支撑杆上,支撑杆的末端还连接有平尾,支撑杆的末端还连接有竖直向上的垂尾;本发明的分离流翼型使流体在前缘削尖点分离,随后气流快速转捩为湍流,湍流可以更好地抵抗大气中的湍流,分离气流会在圆弧襟翼表面再附,形成稳定的的低压涡流区,带来很可观的升力,使飞机取得较好的气动特性和飞行稳定性。
