Abstract
The present invention discloses a kind of air bubble of anti-bullet rotation, and including air bubble gun tube, the bullet support in air bubble gun tube, the separation of the projectile seat device in front of air bubble gun tube, the interior tube section of the air bubble gun tube is polygonal cross-section；When emitting bullet support by gun tube, since bullet support section is to be cooperated with tube section in gun tube by polygonal cross-section, therefore bullet support also avoids rotating in the bullet that circumferentially rotation similar with traditional cylindrical gun tube will not occur, therefore launch, and achievees the purpose that reduce test error.
Description
Technical field
The present invention relates to air bubble technical fields.
Background technique
In foreign object damage (FOD) test, the different postures on aspherical projectile impact to blade influence collision reaction
It is huge, need to take into account, however be used as in traditional experiment guidance shot orbit used in circular section smooth bore big gun or
Rifle cannon is unable to control rotary motion of the bullet in accelerator, it is difficult to control because when rotation causes to strike on blade
Different postures will cause its motion profile to a certain degree in gun tube exit to target plate position while bullet rotates
There is also uncertainties for angle of shock when deviateing scheduled circuit, therefore colliding, cause the error of test result larger.
Summary of the invention
Goal of the invention: present invention aims at a kind of air bubble for improving structure is designed, so that bullet accelerates in gun tube
It does not rotate in the process.
Invention also provides the test methods of this kind of experimental rig.
Technical solution: to achieve the above object, following technical scheme can be used in the present invention:
A kind of air bubble of anti-bullet rotation, bullet support including air bubble gun tube, in air bubble gun tube are located at air
Separation of the projectile seat device in front of big gun gun tube, the interior tube section of the air bubble gun tube are polygonal cross-section；The cross section of the bullet support
It is identical as interior tube section.
The utility model has the advantages that in the present invention, when emitting bullet support by gun tube, since bullet support section is logical with tube section in gun tube
Polygonal cross-section cooperation is crossed, therefore circumferentially the rotation similar with traditional cylindrical gun tube will not occur for bullet support, therefore launch
Bullet also avoids rotating, and achievees the purpose that reduce test error.
Detailed description of the invention

Specific embodiment
It is shown below in conjunction with the embodiment of the present invention to technical solution progress is complete in the embodiment of the present invention, is explicitly described
So, described embodiment is only a part of the embodiments of the present invention, instead of all the embodiments.Based in the present invention
Embodiment, those of ordinary skill in the art's all other embodiment obtained in the case where not making creative work, belongs to
The scope of protection of the invention.
Incorporated by reference to shown in Fig. 1 and Fig. 3, the present invention provides a kind of air bubble of anti-bullet rotation, including air bubble gun tube 1,
Bullet support 2 in air bubble gun tube 1, the separation of the projectile seat device 3 positioned at 1 front of air bubble gun tube, the air bubble gun tube 1 it is interior
14 section of pipe is polygonal cross-section；And the cross section of bullet support 2 is identical as interior tube section, bullet support 2 in inner tube can it is stable to
Preceding movement.And in the present embodiment, a preferred embodiment is that the interior tube section of air bubble gun tube 1 is rectangle, then together
Sample, the cross section of bullet support 2 is similarly rectangle.There is lubricant coating inside the air bubble gun tube 1, reduce bullet support 2 in height
Friction in speed movement with wall surface keeps each bullet as uniform as possible up to gun tube exit velocity.Air bubble gun tube 1 is equipped with
Hatch door 11 after bullet support 2 is put into, shuts hatch door 11 bullet support 2 to be put into inner tube.As shown in figure 4, the front of bullet support 2 is equipped with
For accommodating the accommodating chamber 21 of bullet (not shown).
The separation of the projectile seat device 3 is mounted in front of air bubble gun tube by flange 31, and separation of the projectile seat device 3 includes same with inner tube
The outlet 32 of axis, the cross section of the outlet 32 is less than the cross section of inner tube, so that the bullet support of high-speed flight occurs acutely to touch with it
It hits, achievees the purpose that it is prevented to pass through.After bullet support is blocked, bullet flies under the conditions of inertia from separation of the projectile seat device outlet 32
Out.In the present embodiment, which is square orifice, and the sectional area of the outlet 32 is less than the sectional area of bullet, enables bullet
Outlet 32 is enough passed through to project.
The air bubble gun tube 1 includes upper body half 12 and lower body half 13, and the inside of the upper body half 12 opens up
Fluting, the inside of lower body half 13 open up the lower fluting opposite with upper fluting, merge on the inside of upper body half 12 and lower body half 13
Air bubble gun tube is formed, upper fluting combines formed inner tube with lower fluting.Gun tube is reduced using the split design for opening upper and lower tube body
The difficulty of processing in polygon hollow section.
The operating procedure of air bubble of the present invention is such that
Step 1: being put into the rectangle bullet support of bullet to hatch door is opened, shutting hatch door 1.
Step 2: being filled with high pressure gas, so that gas is calmed the anger and reach specified pressure, opening valve makes air-flow push bullet support hair
It penetrates.
Step 3: bullet support is stopped when carrying projectile flight to gun tube end by separation of the projectile seat device, gun tube end is stayed in.By
Inertia force influence, bullet continue flight forward, until impact target plate.
