Embodiment Construction

[0026] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0027] According to the cracking phenomenon of the feathers when the wings of birds flutter upward, the flexible hinge of the wing installed on the conventional flapping wing realizes the flexibility of the feathers at the rear of the flapping wing, and four cantilever beams protrude from the outer skeleton of the wing rear end to simulate the flying feather Feather shafts and feather flexible hinges realize slight twisting of the feather shafts, and primary flight feathers 1, primary flight feathers 2, secondary flight feathers 1 and secondary flight feathers 2 are also stacked in the order of real birds.

[0028] The present invention is a kind of imitation feather cracking mechanism of miniature flapping wing aircraft, such as figure 1 , figure 2 As shown, it includes body frame 1, wing rear end piece 2, secondary flight feathers 23, secondary fl...

Abstract

The invention discloses a feather cracking simulation lift enhancement mechanism of a micro flapping aircraft. The feather cracking simulation lift enhancement mechanism comprises an aircraft body frame, wing rear-end pieces, a secondary flight feather II, a secondary flight feather I, a primary flight feather II, a primary flight feather I, four flexible feather hinges, a flexible wing hinge and wing front-end pieces, wherein all the parts of the flapping aircraft are arranged in an axial eudipleural manner; the wing front-end pieces are respectively mounted on two sides of the aircraft body frame and can do up-and-down flapping around the aircraft body frame under the traction of a flapping driving device; the wing front-end pieces are connected with the wing rear-end pieces through the flexible wing hinge; the secondary flight feather II, the secondary flight feather I, the primary flight feather II and the primary flight feather I are respectively connected with the wing rear-end pieces through the four flexible feather hinges. The sum of total rising forces of an upper flapping section and a lower flapping section is higher than that of a conventional flapping aircraft which does not simulate cracking; the feather cracking simulation lift enhancement mechanism has the advantages of high pneumatic efficiency, simple structure, high reliability and the like.

Description

technical field [0001] The invention belongs to the technical field of micro-flapping-wing aircraft, and in particular relates to a high-efficiency micro-flapping-wing aircraft imitating feather cracking and increasing lift mechanism. Background technique [0002] Micro flapping wing aircraft is a kind of bionic aircraft, theoretically beyond the scope of traditional aircraft design and aerodynamic research. Compared with traditional fixed-wing and rotary-wing micro-aircraft, the main feature of micro-orthopting-wing aircraft is that it can generate lift and thrust at the same time, and it also has the characteristics of high efficiency, high maneuverability, low noise, and no need for special take-off and landing sites. In nature, almost without exception, all flying creatures use flapping wings to fly. Therefore, so far the researches of various countries on the micro-aircraft have been gradually focused on the micro-flapping-wing aircraft. [0003] From the perspective ...
