The invention relates to the technical field of flapping-wing aircrafts, and provides a bird-imitating active folding wing structure. The structure comprises a ridge frame and folding wing assembliessymmetrically arranged on the two opposite sides of the ridge frame. Each folding wing assembly comprises a wing vein set connected to the ridge frame, a wing membrane set arranged on the wing vein set, a driving assembly arranged on the wing vein set and used for driving the wing vein set to drive the wing membrane set to be folded and reset, and a transmission assembly in transmission connectionwith the driving assembly and the wing vein set. According to the bird-imitating active folding wing structure, the wing vein sets which can rotate to form folding are arranged on the two opposite sides of the ridge frame; the wing membrane sets are arranged on the wing vein sets; the wing vein sets are driven by the driving assemblies and the transmission assemblies which are arranged on the wing vein sets to drive the wing membrane sets to fold and reset; in addition, the active folding wing structure can glide when the wing vein sets and the wing membrane sets of the active folding wing structure are unfolded, so that the active folding wing structure can be switched between a gliding mode and a flapping wing flying mode, and energy consumption and maneuverability are both considered.
本发明涉及扑翼式飞行器技术领域,提出了一种仿鸟主动折叠翼结构,包括脊架和对称设置于其相对两侧的折叠翼组件,该折叠翼组件包括连接于脊架的翼脉组,设置于翼脉组上的翼膜组,设置于翼脉组上的用于驱动翼脉组以带动翼膜组进行折叠和复位的驱动组件,以及传动连接驱动组件和翼脉组的传动组件。该仿鸟主动折叠翼结构通过在其脊架相对两侧设置可转动形成折叠的翼脉组,在翼脉组上设置翼膜组,并通过设置在翼脉组上的驱动组件和传动组件驱动翼脉组来带动翼膜组折叠和复位,实现了折叠翼主动折叠控制的扑翼飞行,另外,该结构还可在其翼脉组和翼膜组展开时滑翔,如此,使得该主动折叠翼结构可切换滑翔与扑翼飞行两种飞行模式,兼顾了能耗与机动性。
