Problems solved by technology

However, it has not been considered to start with the bilateral drive structure itself to realize the lightweight of the flapping wing aircraft
Moreover, the weight of the main body load of the existing flapping-wing aircraft is relatively limited, and there is an urgent need to design an flapping-wing aircraft that can withstand a large load under the condition of light weight of the fuselage body, so as to expand the application scenarios of the flapping-wing aircraft

Abstract

The disclosure relates to an ornithopter. The ornithopter comprises a crank transmission assembly (100), a bracket (500), and a reinforcing plate (600). The crank transmission assembly (100) is arranged at the body of the ornithopter and comprises a first transmission mechanism (101) and a second transmission mechanism (102) which are arranged in a bilateral symmetry mode with respect to the center line of the body of the ornithopter and make contact with each other, and a crank structure (103), and one end of the crank structure (103) is rotatably fixed. The other end of the crank structure (103) is rotatably connected to the first transmission mechanism (101) or the second transmission mechanism (102); the first transmission mechanism (101) and the second transmission mechanism (102) arefixedly mounted on the bracket (500); and a space for accommodating the first transmission mechanism (101) and the second transmission mechanism (102) is formed between the reinforcing plate (600) and the bracket (500).

Description

technical field [0001] The present disclosure relates to the field of aircraft, and more particularly, relates to an orchid-wing aircraft. Background technique [0002] In recent years, aircraft have been favored by more and more people, especially flapping wing aircraft, because of their small size, weak noise, and good concealment, they have great application prospects in civil and military applications. and development space. [0003] Flapping-wing aircraft usually have wings that flutter up and down and their drive mechanisms. At present, the flapping-wing aircraft usually adopts a bilateral drive mode, that is, two sets of transmission mechanisms respectively drive the left and right wings to flutter up and down. This double-sided driving method requires a set of transmission mechanisms on both sides, which not only has a complex structure, but also takes up a relatively large space, making the size of the transmission mechanism larger, which brings great difficulties...
