CN2580393Y - Shell for training in small field - Google Patents

Abstract

The utility model discloses a shell for antiaircraft gun training in small fields. A cartridge is provided with a bullet that a thin-layer outer casing is provided with fine matching objects. The utility model can realize the safety training in small fields, and can also simultaneously achieve the purposes of automatic loading, continuous firing and lifelike training. Simultaneously, compared with the live shell training, the utility model reduces the training cost.

Description

A kind of little place practice projectile

The utility model relates to a kind of antiaircraft gun shell, specifically a kind of little place practice projectile.

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 train for modes such as big gun or use laser shoot simulators.And these equipment can only be trained one, two gunners, can not carry out big gun class rehearsal, and cannon can not load automatically, can not realize burst-firing, so simulation is not strong, does not reach the requirement of combat training.

The purpose of this utility model is to provide a kind of can overcome above-mentioned shortcoming, the novel practice projectile that can carry out the training of little place, security performance is good, training is true to nature and the training cost reduces greatly.

The utility model is achieved in that little place practice projectile, and bullet is housed on cartridge case, and bullet is that mass in small, broken bits is housed in the thin layer shell.

After adopting this structure, this dummy round can load and launches as live shell.When emission, the fire in a stove before fuel is added of cartridge case is impacted and lights propellant powder in the cartridge case, and the gases at high pressure that gun propellant combustion produces promote bullet and launch from gun barrel.Because the shell of bullet is made for the thin layer fragile materials, so after bullet was gone out gun muzzle, its suffered high pressure discharged suddenly, causes the fragmentation of bullet shell, the mass in small, broken bits in the bullet is scattering simultaneously also.The flying distance of bullet is very near like this, can realize little place safety training.Bullet is in the proal while, and the effect of holding one's breath of the inertia of bullet mass in small, broken bits and obturator ring makes barrel pipe recoil, also can reach the purpose of automatic filling, burst-firing simultaneously.Adopt such shell training, can not limited by the place, and train true to nature, simulation is strong, security is secure, the training cost reduce greatly than the live shell training.

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 practice projectile is basic identical with the live shell structure, promptly is provided with obturator ring 3 in the end of cartridge case 5, and the afterbody and the fire in a stove before fuel is added 6 join, and propellant powder 4 is housed in the cartridge case 5.Bullet is equipped with in front portion at cartridge case 5, and the shell 1 of bullet is made by the thin layer plastics, and mass 2 in small, broken bits is housed in the shell.Mass 2 in small, broken bits can be a fine sand, and this raw material is cheap and easy to get, and can play the counterweight effect well.The thickness of the plastic casing 1 of bullet is preferably 2--4mm, makes it both to have certain rigidity with the carrying mass, again can be broken rapidly when bearing high pressure, guarantee training of safety.

Claims (3)

1, a kind of little place practice projectile is equipped with bullet on cartridge case (5), it is characterized in that described bullet is that mass in small, broken bits (2) is housed in thin layer shell (1).

2, little place as claimed in claim 1 practice projectile is characterized in that described mass in small, broken bits (2) is a fine sand.

3, little place as claimed in claim 1 practice projectile, the thickness that it is characterized in that described thin layer shell (1) is 2--4mm.
