Knockout process, evaluation influence the parameters of structural behaviour, have to the hail impact resistance design of composite structure important
Directive significance.
Gas big gun experimental rig is widely used in the experiments such as the experiment of structure penertration resistance, Aircraft Bird-Impact and hail impact, these
Experiment has strict requirements, i.e. bullet that should keep its axis and its heading one as possible before target the posture of body
It causes namely the angle of attack is small as possible.Otherwise just can not guarantee test state accuracy and repeatability.
And in current air bubble experiment, shell is placed in bullet support, when shell is detached from gun muzzle, due to shake and
The influence of de- bullet so that the skyborne flight attitude of shell changes, to influence experimental result, therefore study to have posture
Stable bullet support and the de- device that plays have great importance to structural impact experiment.

Specific implementation mode
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with the specific embodiment of the invention and
Technical solution of the present invention is clearly and completely described in corresponding attached drawing.Obviously, described embodiment is only the present invention one
Section Example, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not doing
Go out the every other embodiment obtained under the premise of creative work, shall fall within the protection scope of the present invention.
The technical solution provided below in conjunction with attached drawing, each embodiment that the present invention will be described in detail.
With reference to figure 1 and Fig. 2, which includes：De- bullet system and systems stabilisation.
Wherein, the de- bullet system includes ring flange 21, slide bar 22, muzzle brake 23, spring 24 and nut 25, ring flange 21
It being connect with gun muzzle by screw thread positioned at 1 front of gun tube, front has a number of slide bar 22 to be connect with ring flange 21 by screw thread,
There is hole corresponding with slide bar on muzzle brake 23, is positioned over 21 front of ring flange across slide bar 22, nut 25 passes through screw thread and slide bar
22 connections are positioned at the right end of slide bar 22, and spring 24 passes through slide bar 22, between muzzle brake 23 and nut 25.
The systems stabilisation includes bullet support 31 and guide pipe 32, and bullet support 31 is positioned in gun tube 1, and the right end of bullet support 31 is provided with
The bullet opening 34 of shell 4 is placed, shell 4 is positioned at bullet opening 34, and 4 rear of shell there are one or more guide pipes 32, leads
It is connect to pipe 32 with shell 4, the pilot hole 33 for placing guide pipe 32 is provided at 34 rears of bullet opening.
Wherein, the guide pipe 32 of systems stabilisation can be tubulose or the shapes such as rodlike, and the material of guide pipe 32 is plastics, wood
The light materials such as material, hollow aluminum, foam.
Also, the guide pipe 32 of systems stabilisation connect by glue with shell 4 or guide pipe 32 and shell 4 it is integrally manufactured.
Further, the length of the guide pipe 32 of systems stabilisation is more than the length of shell 4, i.e. the length of guide pipe 32 is more than big gun
Length of the bullet 4 along 1 direction of gun tube.The quantity of guide pipe 32 can be one or more while be placed on 4 rear of shell.Described
In the case that guide pipe 32 is multiple, multiple guide pipes 32 are uniformly connect with shell.
Wherein, the pilot hole 33 of the bullet support 31 of systems stabilisation is longer than 32 length of guide pipe, is contacted with guide pipe 32 smooth, rubs
It is small to wipe power.
Wherein, the bullet support 31 of systems stabilisation can be circle or other shapes, light using expanded material, timber, nylon etc.
Material can be fabricated separately or with multiple material produced with combination.The bullet support 31 and gun tube 1 of systems stabilisation are in close contact, and
Therebetween using lubricating oil to reduce friction.
Further, the muzzle brake 23 for taking off bullet system is made of steel, and internal circular hole is more than the circumscribed circle ruler of shell 4
It is very little, it is less than the outer diameter of de- ereisma.Wherein, sliding block 26 is provided between the muzzle brake 23 and the spring 24, sliding block 26 passes through
Slide bar 22.As shown, sliding block 26 is circular ring shape, there are a big hole, the diameter of the circular hole to be more than the outer diameter of shell among it.It is sliding
There are multiple small sircle holes on the periphery of block 26, for across slide bar 22.In the embodiment of the present application, the quantity of the slide bar 22 be more than or
Equal to 3, it is preferable that the quantity of the slide bar 22 is 4, correspondingly, also has 4 small circular holes to pass through slide bar on sliding block 26
22。
Further, the shape of shell 4 can be rectangular, cylindrical etc. variously-shaped, and the application is not limited this.
According to the embodiment of the present application, bullet support 31 moves under the promotion of high pressure gas or other active forces along gun tube 1, in big gun
1 exit of pipe, bullet support 31 touch muzzle brake 23, and muzzle brake 23 is behind under the cushioning effect of the spring 24 in face, to bullet support 31
A stable active force is played, and there is sliding block 26 between muzzle brake 23 and slide bar 22, reduces the frictional force with slide bar 22.
Bullet support 31 reduces speed now after touching muzzle brake 23, and shell 4 and guide pipe 32 are together under the action of inertia force
It moves forward, starts to be detached from bullet support 31, as shown in Figure 2 B.Since the length of guide pipe 32 is longer than shell 4 along 1 direction of gun tube
Length, after shell 4 is detached from bullet support 31, the left end of guide pipe 32 is still in bullet support 31, ensure that shell 4 far from bullet
Posture when being still maintained in bullet support 31 after support 31, as shown in Figure 2 C, avoid shell 4 the moment of de- bullet generate deflection from
And influence experimental result.
According to the technique and scheme of the present invention, stablize shell posture by using guide pipe, shell be detached from bullet support after according to
The flight attitude that shell can so be stablized, will not have an impact the shock of shell, make simple of low cost, effective raising
The efficiency of experiment and the quality of experiment.
Example the above is only the implementation of the present invention is not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.Any modification made by all within the spirits and principles of the present invention,
Equivalent replacement, improvement etc., should be included within scope of the presently claimed invention.
