The invention belongs to the field of bionic wings, and discloses a multi-mode bionic wing unit, which can simulate the convergence or stretching action of a humerus-like and radius-like connection structure of a bird towards a bird body, so that a wing section in flight is correspondingly subjected to smaller wind resistance or larger wind resistance, and comprises a foldable main wing, the foldable main wing comprises at least three main wing rib frames and lever connecting rods, all the main wing rib frames are arranged in parallel at intervals, the three main wing rib frames which are continuously adjacent in sequence serve as main wing folding sets, the number of the lever connecting rods corresponds to that of the main wing folding sets, and when the number of the lever connecting rods is larger than one, the lever connecting rods are connected with the main wing folding sets. All the lever connecting rods are parallel to one another, the two ends and the middle of each lever connecting rod are hinged to three main wing rib frames of the main wing folding set respectively, and when the lever connecting rods rotate in a lever mode, the main wing folding set is correspondingly folded or expanded. The invention further discloses a multi-mode bionic aircraft based on the bionic wing unit.
本发明属于仿生翼领域,公开了多模态仿生翼单元,能够对鸟类的类肱骨、桡骨的连接构造整体向鸟躯的收敛或者伸展动作进行仿生,从而对应使得飞行中的翼型受到更小风阻或者受到更大风阻,包括可折叠主翼,可折叠主翼包括主翼肋架和杠杆连杆,主翼肋架的数量为至少三个,所有主翼肋架间隔且平行设置,且将依次连续相邻的三个主翼肋架作为主翼折叠组,杠杆连杆的数量与主翼折叠组对应,且当杠杆连杆的数量大于一个时,所有杠杆连杆相互平行,杠杆连杆的两端及中部分别与主翼折叠组的三个主翼肋架铰接,当杠杆连杆杠杆转动时,主翼折叠组对应折叠或者扩张。本发明还公开了基于上述仿生翼单元的多模态仿生飞行器。
