Abstract

The utility model discloses a shooting training shell for antiaircraft guns. A cartridge is provided with a bullet. The bullet is a guide pipe that a bottom opening of a casing is clamped and provided with tracer mixture. An upper opening of the guide pipe is connected with a cartridge bag. The bullet casing is filled with fine weight objects. The training shell is the same as the ball firing process, the ballistic path is displayable, the shell can be automatically and continuously filled, the continuous shooting is realized, the shooting precision is high, and the command for armies and the system evaluation of artillery squads and artillery groups are realized. The utility model has no chipping harm, has no requirement on training fields and can ensure safety. Compared with the ball firing, the training cost is greatly reduced.

Description

Practice shooting with the training shell

The utility model relates to a kind of antiaircraft gun training shell, and specifically a kind of target practice is with training shell.

Current, because there is not the suitable training shell, when training, the anti-aircraft artillery of army must arrive the spacious unmanned part of desert area or coastal area, face desert or sea and carry out the live shell training.And live shell training cost height, safety is difficult for guaranteeing.Therefore, majority can only adopt with rifle and carry out for modes such as big gun or use laser shoot simulators.These equipment can only be trained one, two gunners, can not carry out the rehearsal of big gun class.And cannon can not load automatically, can not realize burst-firing, so simulation is not strong, does not reach the requirement of combat training.Maximum problem is the examination of can not practicing shooting.

It is a kind of just the same with the ball firing process that the purpose of this utility model is to provide, and fire accuracy height, trajectory can show, can load shell automatically continuously, realize continuous fire, and do not have the brand-new target practice training shell of debris damage.

This training shell can be realized commander and the big gun class and even the big gun group's of army system endurance, and the training court is not required substantially, reduces the training cost greatly and can guarantee safety.

The utility model is achieved in that this target practice is that bullet is housed with the training shell on cartridge case, bullet is to clamp the conduit that fills tracer mixture at the end of housing mouth, and the connection cartridge bag suitable for reading of conduit is filled with mass in small, broken bits in the bullet housing.

After adopting such structure, when bullet was launched in thorax, the fire in a stove before fuel is added was impacted and lights propellant powder in the cartridge case, and the gases at high pressure of generation promote bullet gun muzzle that flies out of suitable rifling high speed rotation forward, flight stability, but pinpointing when lighting tracer mixture.After bullet was gone out gun muzzle, tracer mixture showed its trajectory, was convenient to observe and revise.The bullet back tracer mixture that hits the mark burn and has lighted cartridge bag, makes the bullet self-destruction, forms the fine debris that no longer the human body formation is injured and falls.The proal while of bullet, the effect of holding one's breath of the inertia of bullet mass and obturator ring makes barrel pipe recoil, reaches automatic filling, burst-firing.

Because this process and ball firing process are just the same, fire accuracy height, trajectory can show that therefore this training shell can be realized commander and the big gun class and even the big gun group's of army system endurance.Owing to there is not the generation of injury fragment, therefore the training court do not required substantially, and can guarantee safety again.Compare with the live shell training simultaneously, greatly reduce the training cost and can guarantee safety.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

As shown in Figure 1, this target practice is similar to live shell with the training shell, promptly is provided with obturator ring 4 in the end of cartridge case 7, and the afterbody and the fire in a stove before fuel is added 8 join, and propellant powder 6 is housed in the cartridge case 7, in the front portion of cartridge case 7 bullet are housed.Different is, bullet is to clamp the conduit 5 that fills tracer mixture at the end of housing 1 mouth, and the connection cartridge bag 3 suitable for reading of conduit 5 is filled with mass 2 in small, broken bits in the bullet housing 1.Mass 2 in small, broken bits is preferably fine sand.This raw material is cheap and easy to get, and can play the counterweight effect well.The housing 1 of bullet is preferably the plastics of certain intensity, makes it both to have certain rigidity with the carrying mass, can bear high pressure again, and can brokenly form nothing injury fragment when the bullet self-destruction, to guarantee training of safety.

Claims

1, a kind of target practice is with training shell, on cartridge case (7), bullet is housed, it is characterized in that described bullet is that end mouth at housing (1) clamps the conduit (5) that fills tracer mixture, the connection cartridge bag suitable for reading (3) of conduit (5) is filled with mass in small, broken bits (2) in the bullet housing (1).

2, target practice as claimed in claim 1 is characterized in that with the training shell described mass in small, broken bits (2) is a fine sand.
