One section of gun tube is merely illustrated in Fig. 1, is set at the length direction interval of every section of gun tube 4 of emitter no more than 1m
Put guide rail 5.
The mode of 4 upper mounting rail 5 of gun tube can have a variety of, and Fig. 1 shows a kind of preferable mode, and gun tube 4 corresponds to often
Section guide rail 5 has at least two bolts hole, and bolt 41 penetrates the inner circumferential that guide rail 5 is fastened on gun tube 4 by bolt hole on the outside of gun tube 4
On.
The mode of installation convex block 8 can also have a variety of on annular solid 7, and with reference to Fig. 1, a kind of optional mode is in annular
It is provided with bolt hole and the dowel hole with bolt hole coaxial line on body 7, convex block 8 is by inserting the positioning finger setting of dowel hole
And the bolt by being screwed into bolt hole fastens.
With reference to the right side of Fig. 1, separation of the projectile seat device 9 further includes slide bar 93, and slide bar 93 is fixed on the flange of gun tube 4, annular
Body 7 is passed through and can slided on slide bar 93 by slide bar 93, and annular solid 7 and slide bar 93 are provided with bullet between one end away from gun tube 4
Spring 91.Spring 91 can play cushioning effect.The length and elasticity of different springs 91 are selected according to the length of bullet support 1, makes annular
Body 7 is less than the length of bullet support 1 with gun muzzle distance, so as to ensure to contact with the convex block 8 installed in 7 end face of annular solid in bullet support 1
Before, keep bullet support 1 not rotate by the guide rail 5 of 4 inner wall of gun tube, when bullet support 1 does not also project gun tube 4 completely, the groove of bullet support 1
The convex block 8 of separation of the projectile seat device is just caught in, keeps bullet support 1 not rotated in separation process by the convex block 8 of separation of the projectile seat device.In addition,
The convex block 8 of separation of the projectile seat device can be structure symmetrical above and below, further such that during separation of the projectile seat, bullet support is upper
Lower uniform stressed, avoids because bullet support unbalance stress influences the expeimental cartridge direction of the launch.
It is not shown in figure, which can also the supporting power set for providing gases at high pressure, bullet support 1 and examination thereon
Test bullet to be impacted by gases at high pressure, then gone out from 4 high speed of gun tube.
As shown in Figure 4, Figure 5, which includes bullet support 1, and bullet support 1 has the guide groove of corresponding rails 5, and guide groove is in Fig. 1
In be not shown, it is to be understood that, it is mutually slidably matched with guide rail 5.After experiment ejects gun tube 4, separation of the projectile seat device 9
Convex block 8 will be stretched into the groove of bullet support 1, plays the role of the positioning of bullet support 1, separation of the projectile seat device 9 is under the effect of impact of bullet support 1
Moved along the slide bar 93 for being fixed on gun muzzle end face, while separation bullet support 1 is with expeimental cartridge body, keep bullet support 1 uniformly to peel off,
Make body with not rotated during separation of the projectile seat around its axial line.
As shown in Figure 4 and Figure 5, metal elastic support is cup-shaped, including cylindric wall of cup 1 and circular bottom of a cup 2, wall of cup 1
Openend has the first stress concentration mouth 12, and bottom of a cup 2 also has the second stress concentration mouth 21.
Due to the first stress concentration mouth 12 and the second stress concentration mouth 21, hit bullet support point in metal elastic support
During from device, the first stress concentration mouth 12 of metal elastic support leading portion, the i.e. openend of wall of cup 1 will be torn along its peak stress direction,
And bottom of a cup 2 will also be thought deeply along the peak stress direction of the second stress concentration mouth 21, during tearing, bullet support is hit into bullet support
The impact energy of separator dissipates, and without being partly splashed to outside gun tube, is hit with target piece, influences to test effect.
First stress concentration mouth 12, the second stress concentration mouth 21 can be selected from multiple shapes, as depicted to implement
In example, they are respectively isosceles triangle, its apex angle is 45 °.Isosceles triangle is selected, is conducive to planning from each stress concentration mouth
The path of the tear line of beginning.
As shown in Figure 4, Figure 5, the openend of wall of cup 1 has four the first stress concentration mouths 12, and bottom of a cup 2 has four the
Two stress concentration mouths 21, correspond between the first stress concentration mouth 12 and the second stress concentration mouth 21.In another embodiment,
The two can not also use and correspond to.
With continued reference to Fig. 4, Fig. 5, corresponding first stress concentration mouth 12 and the second stress concentration mouth 21 are by separation of the projectile seat device
Mutual peak stress is in the same plane during effect.
And in another embodiment, corresponding first stress concentration mouth and the second stress concentration mouth are acted on by separation of the projectile seat device
When mutual peak stress stagger, it is not in the same plane.
As shown in figure 5, four the second stress concentration mouths 21 are located at the middle part of bottom of a cup 2, the center hollow out of bottom of a cup 2 so that four
A second stress concentration mouth 21, which is connected to each other, limits the notch of starriness.
First stress concentration mouth 12, the number of the second stress concentration mouth 21 can change, the two can be equal or unequal.
As shown in figure 4, the two annular finishing mating surfaces 11 that there is protrusion to set on the outer circumferential surface of wall of cup 1, annular is matched somebody with somebody
Conjunction face 11 is respectively used to coordinate with gun tube and outside diameter is equal with the internal diameter of gun tube.The precision of two mating annular faces 11 can be higher,
Such as deviation from circular from is 0.01, roughness 0.8.The mating annular face 11 of two finishing is used for the accurate positionin in gun tube
And bullet support obturages rear gases at high pressure in accelerator in gun tube, and during separation of the projectile seat, protect bullet backing portion
Hold completely, be deposited on separation of the projectile seat device.I.e. from the tear line that stress concentration mouth 12,21 is torn to corresponding mating annular face 11
With regard to terminating.
