In the invention, the wings and the ailerons are connected by Kevlar materials so as to realize seamless connection, reduce the air disturbance phenomenon of the surface of the wings on the fly, and be more stable for the flying status; and the lower planes of the wings and the ailerons are connected by adopting arc or an involuted semi-cambered surface, so that the whole unmanned aerial vehicle has light weight and large connection strength, can be folded more than ten thousands of times, and effectively prolongs the service life.
Description
Technical field
The invention belongs to aviation field, relate to unmanned plane, especially a kind of SUAV (small unmanned aerial vehicle) of turbulence.
Background technology
China's SUAV (small unmanned aerial vehicle) industry is started late, in design process aspect the equipment of profile, specification and lift-launch, one is with reference to external active service unmanned plane design, but glass-felt plastic manufacture craft horizontal aspect design route outmoded, cause some model unmanned planes the aspects such as body weight, structure design and strength of material with external nineties like product approximate, not quantum jump too.
In recent years, up-to-date technology and the new material development of China's composite material industry are very fast, composite material is a kind of brand-new material, on aircraft, application is in development phase, because its material light weight, excellent in cushion effect, temperature deformation is little (" creep " that the difference of Yin Wendu causes), antiageing (serviceable bife prolongation), the characteristics such as corrosion prevention, thunder and lightning, static and various storeroom compatibility height, are used very extensive in many industries.
At present, be connected common mechanical hinge or plastic hinge between wing and aileron connect, and the half that is about to several hinges is inlaid on wing, and second half of hinge is inlaid on aileron.The shortcoming that this frame mode exists is: 1, install comparatively complicated; 2, installation effectiveness is low; 3, owing to being a connection, the intensity of connection is limited, and hinge easily comes off, and the life-span is short; 4, weight heavier, 5, there is gap between aileron and wing, easily produce flow-disturbing problem, affect flight efficiency.
By retrieval, not yet find the open source literature identical with present patent application.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, and the SUAV (small unmanned aerial vehicle) of the turbulence of the seamless chain connection of a kind of wing and aileron, half cambered surface rotation is provided.
The present invention solves its technical matters and is achieved through the following technical solutions:
A kind of SUAV (small unmanned aerial vehicle) of turbulence, comprise wing and aileron, aileron hinge is contained in the side of wing, it is characterized in that: described wing adopts Kevlar connecting band to be connected with the upper plane hinged place of aileron, makes clutch place adopt half cambered surface to be connected at aileron and the lower plane of wing.
And the wing of described Kevlar connecting band and both sides and the upper plane of aileron all adopt epoxy resin combination process one insert.
And the section material of described wing and aileron consists of finish coat, fiber, epoxy resin inwards from outside face, Kevlar connecting band level is installed in epoxy resin.
And, at the lower plane of aileron and wing, make clutch place, on the aileron of this clutch place, be installed with a glass colloid with the epoxy resin one of aileron lower plane inboard, this glass colloid and wing lower plane adopt half cambered surface sliding block joint.
And, in aileron and wing both sides, be all fixed with the support bar of wooden structures.
Advantage of the present invention and good effect are:
1,, in the present invention, aileron adopts Kevlar material with being connected of wing, realizes seamless link, makes the surface of wing reduce air disturbance phenomenon awing, makes the attitude of flight more stable.
2, in the present invention, adopt the mode that Kevlar material one is a line in main wing with the connection mode of aileron to be connected, lightweight, Joint strenght is large, folding number of times can, more than ten thousand times, effectively extend service life.
3, in the present invention, on the aileron of lower plane clutch place of aileron and wing, be installed with a glass colloid with the epoxy resin one of aileron lower plane inboard, this glass colloid adopts half cambered surface of circular arc or involute to be connected with wing lower plane, guaranteed that aileron keeps and the contacting of wing lower plane when upper and lower rotation, has effectively avoided air disturbance problem.

The specific embodiment
Below in conjunction with accompanying drawing, by specific embodiment, the invention will be further described, and following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
A SUAV (small unmanned aerial vehicle) for turbulence, comprises wing 1 and aileron 4, and aileron hinge is contained in the side of wing.Innovative point of the present invention is:
(1) wing adopts 3 encapsulation of Kevlar connecting band to be connected with the upper plane hinged place 2 of aileron, the wing of this Kevlar connecting band and both sides and the upper plane of aileron all adopt epoxy resin 8 combination process one perfusion inserts, specifically, referring to Fig. 6, the section material of wing and aileron consists of finish coat 6, fiber 7, epoxy resin inwards from outside face, and Kevlar connecting band level is installed in epoxy resin.
(2) at the lower plane of aileron and wing, make clutch place, on the aileron of this clutch place, be installed with a glass colloid 5 with the epoxy resin one of aileron lower plane inboard, this glass colloid is that mould compacting forms, it adopts half cambered surface of circular arc or involute to be connected with wing lower plane, to guarantee glass colloid the contacting of maintenance and wing lower plane when the upper and lower rotation.In order to strengthen aileron and the wing intensity in clutch place, in aileron and wing both sides, be all fixed with the support bar 9 of wooden structures.
In the present invention, on wing and aileron, the connecting sewing hinged place of plane does not have gap under Realize; It is also seamless at aileron, upwarping, have a downwarp 30 ° time.
In the present invention, in clutch place of wing and aileron lower plane, when aileron is in wing Realize, aileron, by the made circular arc camber of the glass colloid plane under the wings of an airplane of trackslipping, does not have gap; When aileron upwarps and have a downwarp 30 ° of angles, all there is no gap, therefore, in the time of flight, just can not produce air disturbance.
Kevlar of the present invention (Kevlar) connecting band, this material is the aromatic polyamide fibre one of (being called for short " aramid fiber "), invented the sixties by Dupont E.I.Du Pont Company, is the registration goods of E.I.Du Pont Company.Pure Kevlar line is to select the temperature-resistant material braiding of high burning-point to form, present aviation and military parachute, explosion-proof, the shellproof Kevlars that adopt more.
