Abstract
The invention discloses a kind of symmetrical primary and secondary bilayer flapping wing mechanism, structure on two sides is full symmetric, and unilateral mechanism includes crank (1), bifurcated connecting rod (2), plain connecting rod (3), female wing rocking bar (4), sub- wing rocking bar (5).The linkage of primary and secondary double-vane is realized with plain connecting rod by the way that bifurcated connecting rod is used in combination, the symmetric motion of the both sides primary and secondary wing is realized by double-crank driving.The invention can produce lift during female wing lifts by the sub- wing, and because the sub- wing is located at the low lift-to-drag ratios area in female wing root portion, fluttering for the sub- wing can effectively improve the lift generation efficiency in female wing root portion.Mechanism of the present invention is simple, in light weight.
Description
Technical field
The invention belongs to aeroplane structure design, and in particular to a kind of symmetrical primary and secondary bilayer flapping-wing aircraft mechanism.
Background technology
More common in flapping wing aircraft is single flapping wing aircraft, and its is simple in construction, light weight, but when flapping wing is lifted upwards
Lift can not be provided when rising and flapping wing root wobble amplitude is small, and lift generation efficiency is very low.
Existing double flapping wing aircrafts are asymmetric double flapping wing, and the lift that both sides provide is asymmetric, and flapping wing was fluttered
Cheng Zhong, interfere seriously, flapping wing root wobble amplitude is small, and lift generation efficiency is relatively low.
The content of the invention
The technical problem to be solved in the present invention is solve common individual layer flapping wing and asymmetric double-vane lift efficiency is low
Problem, improve flapping wing lift efficiency.
A kind of symmetrical primary and secondary bilayer flapping wing mechanism is provided for the technical solution of the present invention that solves the above problems, structure on two sides is complete
Symmetrically, unilateral mechanism includes crank, bifurcated connecting rod, plain connecting rod, female wing rocking bar, sub- wing rocking bar, described point of the crank connection
The host node of connecting rod is pitched, the main split end of the bifurcated connecting rod connects the root of female wing rocking bar, the root of female wing rocking bar
Between portion and taper is some fixing point D, and the fixing point D dead axles are connected on support, when described point of crank driving
When pitching link motion, the bifurcated connecting rod drives female wing rocking bar to be moved around the fixing point D, secondary point of the bifurcated connecting rod
Branch end connects one end of plain connecting rod, and the other end of the plain connecting rod connects the sub- wing rocking bar, the root of the sub- wing rocking bar
Portion's F dead axles are connected on support, and when the crank drives the bifurcated link motion, the bifurcated connecting rod drives the sub- wing
Rocking bar moves around the root F.
A kind of symmetrical primary and secondary bilayer flapping wing mechanism provided by the invention, it is real with plain connecting rod by the way that bifurcated connecting rod is used in combination
The linkage of existing primary and secondary double-vane, the symmetric motion of the both sides primary and secondary wing is realized by double-crank driving.The invention can lift in female wing
During lift produced by the sub- wing, because the sub- wing is located at the low lift-to-drag ratios area in female wing root portion, fluttering for the sub- wing can effectively improve
The lift generation efficiency in female wing root portion.Mechanism of the present invention is simple, in light weight.
Brief description of the drawings
Specific embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings, wherein：
Fig. 1 is symmetrical primary and secondary double-vane flapping wing mechanism schematic diagram；
Fig. 2 is symmetrical primary and secondary double-vane flapping wing mechanism composition schematic diagram.
Embodiment
The present invention is described in further detail below.Referring to Fig. 2, a kind of symmetrical primary and secondary bilayer flapping wing mechanism, unilateral machine
Structure includes crank 1, bifurcated connecting rod 2, plain connecting rod 3, female wing rocking bar 4, sub- wing rocking bar 5, and the crank 1 connects the bifurcated connecting rod
2 host node, the main split end of the bifurcated connecting rod 2 connect the root of female wing rocking bar 4, the root of female wing rocking bar 4
Between taper is some fixing point D, and the fixing point D dead axles are connected on fixed support 7, when the crank 1 drives institute
When stating the motion of bifurcated connecting rod 2, the bifurcated connecting rod 2 drives female wing rocking bar 4 to be moved around the fixing point D, and the bifurcated connects
One end of the secondary branch end connection plain connecting rod 3 of bar 2, the other end of the plain connecting rod 3 connects the sub- wing rocking bar 5, described
The root F dead axles of sub- wing rocking bar 5 are connected on fixed support 7, described when the crank 1 drives the bifurcated connecting rod 2 to move
Bifurcated connecting rod 2 drives the sub- wing rocking bar 5 to be moved around the root F.Left and right sides mechanism is full symmetric.Whole flapping wing mechanism
Power resources are that the rotation of direct-flow micromachine is delivered on driven pulley 6 by gear reduction unit, and driven pulley 6 drives crank 1
Fixed-axis rotation is done around central point O.
