Plate, right sealing plate are separately connected, while left link block and right link block carry the revolute pair equipped with bearing, and the rear is installed on
Between left link block and right link block, to realize the rotation of rear；The driving device is made of steering engine and silk thread, and the one of silk thread
End is fixed on rear front end, and the other end is wound in the output end of steering engine, and when steering engine output end rotates, tightened wire drives rear
Around the by-produced rotation of rotation；The upper and lower surface of wing is covered with flexible covering, when rear carries out bending variation, aerofoil surface meeting
It changes with the change of aerofoil profile, realizes the change wing of entire wing.
Preferably, the steering engine can adjust output angle, angle adjustable ranging from 0 by the primary control program of underwater glider
~180 degree realizes the multi-angle variation of flexible trailing edge wing to control the overbending direction and bending angle of flexible trailing edge wing.
Compared with prior art, advantageous effect caused by technical scheme of the present invention is：
The present invention can be achieved the flexible of underwater glider wing and become rear mode, and basic structure is simple, without redundancy section,
It is novel reliable to become rear mode, makes wing lightweight and can deform by continuous flexible to realize maximized effective deformation.Steering engine
Output angle ranging from 0~180 degree, in different range of angles of attack, being targetedly changed to trailing edge can be with
Effectively improve the navigation economy and Maneuverability of underwater glider.

Specific implementation mode
In order to further understand the content, features and effects of the present invention, the following examples are hereby given, and coordinate attached drawing
Detailed description are as follows：
It please refers to Fig.1 to Fig.3, a kind of flexible change rear underwater glider wing, including left sealing plate 1, right sealing plate 2, Zuo Lian
Connect block 3, right link block 4, the leading edge of a wing 5, trailing edge 6, chock 7 and nacelle connecting plate.
Wherein, left sealing plate 1 is the root portion of wing entirety, and part is in direct contact with underwater glider main body for wing,
There is notch.Right sealing plate 2 is the wingtip part of wing entirety, there is notch.The fore-end that the leading edge of a wing 5 possesses NACA 0012 is bent
There is notch at face aerofoil profile, 5 both ends of the leading edge of a wing, are assembled together by chock 7 and left sealing plate 1, right sealing plate 2.Left link block 3 is main
It is to provide revolute pair for trailing edge 6, and connect with left sealing plate 1.Likewise, right link block 4 also has the rotation of trailing edge 6
Pair, while connecting right sealing plate 2.The basic structure for becoming rear wing has been collectively constituted above.It can be by changing trailing edge
Overbending direction and angle coordinate different motor patterns, improve the movenent performance of underwater glider.
Space between the leading edge of a wing and rear is used to install the driving device 10 for becoming rear.Driving device is by steering engine 10-1
It is formed with silk thread 10-2, entire wing is connect by connecting plate with underwater glider main body, and control circuit needed for driving device is logical
It crosses left sealing plate 1 to introduce inside wing, to control trailing edge, realizes the change rear action of wing.Finally, in the top and bottom of wing
The wing cover 9 for enclosing elastic material is divided into covering 9-1 and lower covering 9-2, and covering 9 is flexible material, has certain bullet
Property and ductility, can change with the variation of air-foil.The entire flexible aerofoil profile for becoming rear wing is set to be essentially NACA
0012 curved surface aerofoil profile.
The change rear mode of the present invention refers to Fig. 4-1 and Fig. 4-2, wherein the change rear of the flexible trailing edge wing is dynamic
Make to complete by way of steering engine 10-1 and silk thread 10-2 transmissions.One end of steering engine output end and silk thread is fixed, silk thread
The other end is fixed with trailing edge front end, and when steering engine output end rotates, silk thread is tensed, and then pulls rear, and rear is made to rotate
By-produced rotation drift angle is moved, completes to become rear action.θ refers to the bending angle of rear after wing variation in figure.
The flexible trailing edge variation of the wing of the present invention can be realized by lower step：
1. providing pwm signal to steering engine signal end by the main control unit in underwater glider nacelle, height in pwm signal
Level accounting determines steering engine corner.Steering engine corner corresponding to rear initial position angle is 90 °；
2. steering engine hard-over is 180 °.In the present invention, steering engine can make rear generate the maximum angle that curves as steering engine turn
60 ° and 120 ° of angle, the corresponding maximum bending angle of rear are 16 °；
3. the bending that the corner by controlling steering engine makes trailing edge generate different angle changes.
The present invention is not limited to embodiments described above.Above the description of specific implementation mode is intended to describe and say
Bright technical scheme of the present invention, the above mentioned embodiment is only schematical, is not restrictive.This is not being departed from
