One-way flapping wing of thin-net-shaped support with multiple thin film sheets

Abstract

The invention discloses a one-way flapping wing of a thin-net-shaped support with multiple thin film sheets. The one-way flapping wing of the thin-net-shaped support with the multiple thin film sheets is provided with a machine body, transmission devices are installed on the two sides of the machine body, and supports are installed on the two sides of each transmission device respectively; a one-way flapping wing support is composed of a support body and a thin-net-shaped structure, the edge of one side of each thin film sheet is fixed to the thin-net-shaped structure, and the other side of each thin film sheet freely moves; and one end of each limiting silk thread is connected to the thin-net-shaped structure, the other end of each limiting silk thread is connected to the movable edge of the corresponding thin film sheet, and all the thin film sheets are arranged on the same side of the thin-net-shaped structure. According to the one-way flapping wing, the net-shaped flapping wing support structure is adopted, the thin film sheets are automatically opened and closed under the air effect, different air resistances are generated, the thin film sheets are connected with several corresponding points on a support silk screen through length-limited thin silk threads or thin strips, and therefore the motion scope of the thin film sheets is limited; each flapping wing thin film is formed by the multiple thin film sheets, and an ornithopter can obtain the lifting force through simple up-and-down flapping of the support.

Description

technical field [0001] The invention belongs to the technical field of flapping aircraft, and in particular relates to a one-way flapping wing with a fine mesh support and multi-film sheets. Background technique [0002] The flapping wing is the main power structure of the flapping wing. The flapping wings act on the air to generate lift and forward propulsion. Modern flapping aircraft can be divided into bird-like flapping wings and insect-like flapping wings in principle. From the perspective of bionics, the existing flapping wing is a layer of film fixed on a specific support. The structure of the support generally imitates the structure of a bird's wing or an insect's wing. When the flapping wing shines on a bird or It is the flying behavior of insects that disturb the air around the flapping wings when they swing up and down, generating the power of flight. [0003] From the perspective of bionics, the designed flapping wing is composed of a whole piece of film, or a ...
