Abstract

The utility model relates to a high explosive shell and launching-apparatus, characterized in that a shell body is divided into an explosive body part and a guide part made of a fine steel tube. The explosive part reveals and launch is done by that the guide part inserts into a launching-apparatus sleeve whose one end is closed. Launching explosive is arranged in the guide part made by the fine steel tube. Radial expansion is generated by the guide part steel tube under the pressure of the explosive at the time of launching. Obturation with the inner wall of the launching-apparatus sleeve is formed. Simultaneously, self rotation is generated by means of the friction with the inner wall to stabilize a trajectory. The shell is lighter than the existing bar type bun explosive shell by 40%. Correspondingly, the explosive shell launching-apparatus is lighter than the existing barrel type launching-apparatus by more than 80%.

Description

High explosive shell and its launching-apparatus

The utility model belongs to the gunpowder impelling class of infantry's light weapons.

The rifle grenade that the existing individual soldier of ground force uses can be divided three classes basically at radiation pattern: 1. the rod-type rifle grenade with the France Lv Xieer company production of the middle and later periods eighties is representative, metal bullet trap is housed on the body of this rifle grenade, it is enclosed within on the muzzle from the muzzle front portion, by common rifle live ammunition; Because of bullet trap and tail pipe reach more than 200 millimeters, the weight of bullet trap and tail pipe surpasses 50% of complete round weight, thereby the bullet of rifle grenade is heavy excessive, and the power of sentencing the accuser to the punishment facing the person he falsely accused during emission is excessive, influences shooter's normal use.2.70 the small bore rifle howitzer by special-purpose launching tube emission of age with United States Equipment is the cartridge type grenade launcher of representative.PIM203 type grenade launcher for example; Its radiation pattern more complicated, operational motion is too much, easily maltosemalt sugar mistake opportunity of combat.Launching tube weighs more than 1.6 kilograms, and is very big to the weight increase of rifle, combines difficulty with the rifle body.3.70 the age not northern China industrial group also manufactured experimently the rocket propulsion grenade.This grenade is to be launched by the gunpowder on the handle, and handle props up in ground during emission, and its major defect is that accuracy at target is not high.The common drawback of above-mentioned three kinds of emission forms is: emitter and howitzer weight are big, carry limited amount, maintenance inconvenience.The howitzer power is also not enough, particularly uses broken first rifle grenade.

The utility model purpose is 1. to alleviate the weight of existing rifle grenade body, the recoil when reducing emission, or increase the effective weight of howitzer explosive component, or increase the range of howitzer; 2. alleviate the weight of transmitter; 3. simplification step of transmitting reduces load, and artillery is carried out standardization.

Fig. 1 is a schematic diagram of the present utility model.In order to alleviate rifle grenade weight, the body of rifle grenade is divided into explosive component and guide part two parts, and explosive component is identical with original rifle grenade, and this paper does not do and pays opinion.What core of the present utility model was discussed is targeting part, and guide part is that fine steel tube is made, and is rigidly connected with body, puts emission powder charge, the fire in a stove before fuel is added and delay cell in the steel pipe.Guide part with rifle grenade during emission inserts in the transmitter thorax, sends out the fire in a stove before fuel is added by the striker percussion fire in a stove before fuel is added or electric shock, and after the impulse charge burning, guide part is done accelerated motion along the transmitter inner hole wall, finishes the emission of rifle grenade.The fine steel tube of guide part is radial deformation under the pressure of propellant powder, with the helix sliding friction of transmitter thorax wall, gives the howitzer body with rotational velocity, keeps the body flight stability.

The utility model is compared with existing various rifle grenades has following advantage: 1, aspect the howitzer body, compare and can alleviate 40% weight with the rifle grenade of pouncing on ereisma that has that French Lv Xieer company produces; Compare with corresponding rifle grenade with U.S. PIM203 transmitter, removed the shell case of rifle grenade from, reduced transmitter volume and structure, only the shell case loss of weight just makes the whole weight that plays reduce 30%.Because bullet heavily reduces, and can reduce the power of sentencing the accuser to the punishment facing the person he falsely accused under the identical condition of initial velocity, or increase power under the identical condition of weight; Or under the condition that does not increase recoil, strengthen initial velocity, improve range.2, transmitter is small and exquisite can be installed on the different firearms flexibly, and as rifle, tommy gun even pistol, special heavy rifle grenade and grenade launcher can be directly with ground or other holder supports shootings.Thereby whole system is in light weight.3, because of body structure is simple, transmitter is small and exquisite, and system cost reduces, and uses and tie up the expansion easy maintenance, can use in a large number in the actual combat.4, the combat readiness time weak point can in seconds be finished the overall process that shooting the aiming emission.This rifle grenade does not have the propellant powder shell, does not have the ejection action, thereby fight firing rate height.This rifle grenade in case of emergency can replace grenade, and hand is thrown and used.5, do not influence the normal shooting of bullet.6。Can launch other bullet kind, as signal flare aerosol bomb and flare or the like.

The description of the drawings

Fig. 1 is a schematic diagram of the present utility model.1 is the explosive component of howitzer body; 2 is the rifle grenade guide part.

Fig. 2 is the schematic diagram that transmitter is positioned at installing under the gun barrel.1 is the explosive component of howitzer body; 2 is the rifle grenade guide part, and the fire in a stove before fuel is added is housed in the guide part, propellant powder and time-delay fuze; 3 is transmitter and firing lock; 4 is gun barrel.

Fig. 3 is boundling emission principle figure, and each transmitter sleeve pipe 5 is rigidly fixed on the seat 6; 7 for adjusting support.

Fig. 4 is the schematic diagram that heavy howitzer and transmitter thereof use separately.8 are the emission sleeve; 9 is seat, and firing lock and sight are omitted.

Embodiment of the present utility model is: one, aspect the howitzer body, the howitzer guide part is made by sheet steel pipe, and the outer surface of guide part and transmitter endoporus are slidingly matched, the endoporus dress propellant powder and the fire in a stove before fuel is added of guide part.Guide part spout endoporus is tapering slightly, and to guarantee that guide part produces small expansion under gunpowder pressure, airtight powder pressure makes body produce spinning motion on the other hand under the helix of transmitter drives on the one hand.Because it is very thin that guide part can be done, and save a large amount of metals, thereby whole rifle grenade can reduce weight significantly.Two, aspect grenade launcher, the material of grenade launcher sleeve can be selected high strength alloy steel for use, and bore area is processed into helix, bore area and howitzer guide part outer cylinder are slidingly matched, be convenient to shoot, hammer and striker are installed in the sealing of transmitter rear end face.Compare with U.S. PIM203 launching tube, volume reduces greatly, has cancelled the shell case of rifle grenade on the other hand on howitzer.Transmitter has three kinds of reasonable types of service:

1. transmitter is installed in below the gun barrel, as Fig. 2.This mode adopts dependable performance on U.S. PIM203 grenade launcher.Difference is: the small volume and less weight of this emitter structures, and very little to the gun weightening finish, do not increase the fight burden, each soldier all can adopt.On mini-submachine gun, also can adorn usefulness especially with the fight pistol.Rifle grenade is directly packed into from the front, does not have the ejection action, fight firing rate height.

2. the transmitter boundling is installed and used, as Fig. 3.This mode can be launched a large amount of howitzers to the target area in a short period of time, realizes that the firepower transmitter rigid attachment in the operation of individual soldier or group becomes as a whole, unified aiming, unified emission.This radiation pattern mainly is to carry out indirect fire, but also can directly shoot when urgent.

3. use separately, as Fig. 4.To heavy howitzer such as antitank high explosive anti-tank cartridge or the like, can use dedicated transmitter, replace rocket launcher and recoilless gun.Transmitter carries seat and sight, and seat props up on heatable adobe sleeping platform, rock or other fastening supporters during emission.Under identical projectile initial velocity, the weight of this grenade launcher is lighter than rocket launcher.
