Bidirectional synchronous automatic turning flapping-wing aircraft

Abstract

A bidirectional synchronous automatic turning flapping-wing aircraft belongs to the field of astronautic bionic aircraft device, comprising an airframe (8), a wing flapping mechanism (1), a bidirectional synchronous output deceleration mechanism (2), a connecting rod (3), an airfoil (4), an empennage control mechanism (5) and an empennage (6); the bidirectional synchronous automatic turning flapping-wing aircraft is characterized in that the wing flapping mechanism (1) comprises a crossed frame (10) and two wing roots (11); the crossed frame (10) is installed on the front end of the airframe (8) through a bearing; two wing roots (11) are respectively installed on two sides of the crossed frame (10); the airfoil (4) is connected with the wing root (11) through a wing bone; the bidirectional synchronous output deceleration mechanism (2) is connected with the wing root (11) through the connecting rod (3); the empennage control mechanism (5) is installed on the rear end of the airframe (8); the empennage (6) is connected with the empennage control mechanism (5). The airfoil is in spot connection with the airframe and performs the bidirectional synchronous automatic turning with high flying efficiency.

Description

technical field [0001] The invention relates to a two-way synchronous automatic flipping wing plane, which belongs to the field of aerospace bionic aircraft equipment, and specifically relates to a two-way synchronous automatic flipping wing plane. Background technique [0002] In nature, both birds and insects fly by flapping their wings. In addition to providing greater thrust and improving flight efficiency, this flying mode by flapping the wings up and down can also enable the small aircraft to achieve more flexible flight actions. [0003] At present, the flapping-wing aircraft developed by people mainly has the following defects: 1. Most of the wings can only perform simple flapping up and down, and cannot be turned over automatically. This is far from the actual flying state of flapping animals. When winged animals fly, the wings are not only simple flapping up and down, but also accompanied by complex turning movements; 2. The inner side of the wing is connected to ...

Problems solved by technology

[0003] At present, the flapping-wing aircraft developed by people mainly has the following defects: 1. Most of the wings can only perform simple flapping up and down, and cannot be turned over automatically. This is far from the actual flying state of flapping animals. When winged animals fly, the wings are not only simple flapping up and down, but also accompanied by complex turning movements; 2. The inner side of the wing is connected to the fuselage as a whole, and it is connected with the fuselage by a "line", which is similar to that of birds and insects. Wings are also very different. Whether it is a bird or an insect, their wings are connected to the body through the wing root, which is a "point" connection instead of a "line" connection, so the wings have a good degree of freedom (bat's The wings and the body are in "line" contact, because the wings are elastic membranes, so they have a degree of freedom, which is different from birds and insects); 3. Most of the wings are designed in one piece, and when the wings flutter up and down, they cannot be adjusted according to needs The force bearing area of ​​the wing reduces the resistance. The wings of birds can expand and contract when flapping. There is a certain gap between the main and aileron. When flapping down, the gap is closed. Open, the resistance is small, which is good for generating lift

Due to the elastic connection between the two sections of span-wise beams, this design can reduce the force area of ​​the wing when it flaps upwards to a certain extent, thereby reducing the resistance of the upwards flapping. No gap is still a whole, so the way of opening the gap between the wings cannot be used to further reduce the resistance when the wings are flapping, which makes the flying efficiency of the flapping wing aircraft not ideal
