Embodiment Construction

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0026] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations or...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of flapping-wing aircraft, and more specifically relates to a bird-like active folding wing structure. Background technique [0002] The concept of morphing wing (morphing wing) can be traced back to the early 20th century. The purpose of the design is to adjust the shape of the wing (such as the sweep angle, wingspan, wing area, etc.), so that the fixed-wing aircraft can adapt to cruise and high speed. Two flight modes on demand. However, traditional deformed-wing aircraft consider the airfoil as a rigid structure for adjustment, which is not suitable for miniaturized flapping-wing aircraft equipped with flexible wings. [0003] The imitation objects of the flapping-wing bionic aircraft are roughly three types of birds, bats and insects. Insects need to flap their wings at high speed to stay in the air; although bats have low flapping frequency, their wing surface weight accounts for a large part of their...
