BG457Y1 - Fragmentation grenade - Google Patents

Abstract

The grenade has greater combat destruction effectiveness and it is possible to preset the number and the weight of the fragments and to increase their quantity. It is made of an warhead and an ejection motor which guarantees the sight firing distance. The warhead contains a casing with trapeze-shaped cut grooves in which a track grating and explosive are fitted in the form of charges fastened by a passage bottom. The passage bottom contains a primer-detonatr. The primer initiating the explosive is mounted in the front end of the housing. To the passage bottom the ejecting motor is screwed, containing a burning shell casing in which a tube is fitted having a gunpowder charge fitted on it and with a stabilizer mounted at one of its ends. The tube has bored holes for the ignition of the charge, and the stabilzer consists of blades which are not unfolding. 1 claim, 3 figures

Description

Technical field

The utility model will find application in ammunition equipment, and more particularly in round-robin ammunition.

BACKGROUND OF THE INVENTION

Known fragmentation grenades with a whole body. The characteristic of these structures is the arbitrary fragmentation of the shell of fragments.

A fragmented projectile is known, the housing of which is made up of prefabricated elements in the form of a pre-folded spring made of a square rod with cuts or a package of pre-cut rings / 1 /. Characteristic of this construction is the limited number of fragments from the length of the housing.

Known is a high-explosive grenade, the body of which is made up of two rows of finished killing elements in the form of spirals with trapezoidal section or in the form of a package of pre-cut rings / 2 /. Characteristic of this construction is the large weight of the warhead, which is why it is necessary to use a jet engine and pre-prepare the kill elements.

The technical nature of the utility model

Pre-setting the number and weight of the fragments and increasing their quantity was achieved in a utility model consisting of a warhead and an ejector engine. The warhead comprises a trapezoidal groove housing housing a forming grate and explosive substance in the form of checkers fitted with a transition bottom. An igniter capsule is placed in the transition bottom. The fuse that triggers the explosive is screwed into the front of the housing. An ejector motor is screwed to the transition bottom. The ejector motor contains a combustion sleeve in which a tube with a gunpowder charge and a stabilizer tube wound at one end of the tube are housed. The pipe has drilled holes for firing the gunpowder charge. The stabilizer is screwed to the tube and consists of insoluble feathers.

Increased combat effectiveness in the destruction of the fragmentation grenade is achieved by fragmenting the shell of a specified number of fragments with a predetermined mass determined by the trapezoidal grooves of the shell and the forming grid. The target firing distance is provided by the ejector motor.

Examples of implementation of the utility model

The utility model consists of a warhead and an ejection engine 2. The warhead 1 comprises a housing with trapezoidal grooves 3 in which a forming grate 4 and an explosive substance in the form of checkers 11 fitted with a transition bottom 5 are placed. the igniter cap is inserted 6. The blower 10 which initiates the explosive lies curled in the front of the housing 3. A discharge motor 2 is screwed to the transition bottom 5. The blower motor 2 contains a combustion sleeve 12 in which a tube 7 is disposed thereon. gunpowder charge 8 and screwed in one end of tube 7 stabilizer 9. Pipe 7 has drilled holes for igniting gunpowder charge

8. The stabilizer 9 is screwed onto the tube 7 and consists of insoluble feathers.

Application of utility model

After piercing the igniter capsule 6, the fire beam from it ignites the gunpowder charge 8 of the ejection engine 2, which results in the grenade being given the necessary initial speed to achieve the target firing target.

In the encounter with a barrier, the blasting device 10 is triggered, which initiates the blasting substance 11 and, through the forming grate 4, the housing with trapezoidal grooves 3 is broken into a fixed number of fragments of a given mass.

Claims (1)

Claims 1. A fragmentation grenade consisting of an ejection engine comprising a combustion sleeve in which a tube with a gunpowder charge is mounted thereon and a stabilizer mounted on one end of the tube and a warhead comprising a housing with an explosive therein inserted therein. checkers and a fuse screwed to the housing for initiating the explosive, characterized in that a forming lattice (4) is provided in the housing with trapezoidal grooves (4) held by a transition bottom (5) in which a capsule is placed. - igniter (6), such as a removable ejector (2) is mounted to the transition bottom (5), in which the shroud 5 (7) has drilled holes for igniting the gunpowder charge (8) and the stabilizer (9) consisting of insoluble feathers is movable to the pipe (7).
