Ornithopter device of mirror symmetry type double-four-bar-linkage structure

Abstract

The invention belongs to the technical field of ornithopter manufacturing and particularly relates to an ornithopter device of a mirror symmetry type double-four-bar-linkage structure. According to the main structure, the ornithopter device comprises a left gear, a left outer connection bar, a left power machine, a left wing, a left inner connection bar, main frameworks, pinna rods, pinnae, a right gear, a right outer connection bar, a support, a right wing, a right inner connection bar, a machine body, a machine head, a machine main body, a machine tail, a left connection bar and a right connection bar. The left outer connection bar, the left inner connection bar, the left connection bar and the main framework of the left wing and the right outer connection bar, the right inner connection bar, the right connection bar and the main framework of the right wing form the mirror symmetry type double-four-bar-linkage structure with the center axis of the machine body as the center and provide symmetric flapping power for the left wing and the right wing. On the basis of the principle that the resistance difference formed when bird wings flap up and down provides ascending force for flying, the flying mechanism of a bird flying state is achieved. The ornithopter device is simple in structure, scientific in principle, low in manufacturing cost, easy to regulate and control, good in flying effect and wide in application prospect.

Description

Technical field: [0001] The invention belongs to the technical field of orthopter preparation, and in particular relates to an orthopter device with a mirror-image symmetrical double four-bar linkage structure, which utilizes the wing design of a bird's wing structure to realize the flight control function. Background technique: [0002] For a long time, people have dreamed of being able to fly in the sky like birds. Many people imitated the wings of birds and tried to fly, but they failed; After learning some flight principles, I found that the shape of the bird's wings is curved. The upper surface of the wing is curved. The principle of wing flight, after a long period of discussion and research, people have found that in addition to the profile of the wing providing lift during high-speed movement, the muscles of the bird and the structure of the wing itself are also very important for the adaptive adjustment of the airflow. Birds The pinnae on the feathers are asymmetri...

[0004] At present, according to the documents of U.S. Patent No. US7255305B2, US7607610B1, US7215305B2, US6802473, US7600712, US4139171, US5899408, US7007889, US7963478, US6824094, US7410121 and US7255305, the asymmetry and fluttering of birds' feathers, and feather flapping are mentioned respectively. There is no mention of the opening and closing of feathers, but there is no mention of the concept that this opening and closing provides lift for birds. In many documents and reports, there is no mention of the difference in resistance formed by the wings of birds flapping up and down, let alone A plan to design an orthopter based on the concept of drag difference is disclosed
