Abstract

FIELD: armament. SUBSTANCE: feed path for an automatic grenade launcher mounted on a combat vehicle turret comprises a magazine with vertically installed grenades connected by links forming a belt, brought to the grenade launcher through a guide neck with rollers and a cylindrical pipe fixed on the magazine along the axis of rotation of the grenade launcher. A curved neck is placed between the cylindrical pipe and the receiving window of the grenade launcher, such that a cover with a rectangular window is fixed overlappingly on the end of the cylindrical pipe, to which the end of the curved neck is welded. Furthermore, the receiving window of the grenade launcher is shifted from its axis of rotation forward in the direction of firing. EFFECT: elimination of delays in grenade launcher firing due to jamming of the belt with grenades in the feed path. 1 cl, 3 dwg

Claims (1)

A feed path for an automatic grenade launcher mounted on a combat vehicle turret, comprising a magazine with vertically mounted grenades connected by links that form a belt fed to the grenade launcher through a guide neck with rollers and a cylindrical tube secured to the magazine along the axis of rotation of the grenade launcher, characterized in that a curved neck is placed between the cylindrical tube and the receiving window of the grenade launcher in such a way that a cover with a rectangular window is overlapped on the end of the cylindrical tube, to which the end of the curved neck is welded, in addition, the receiving window of the grenade launcher is offset from the axis of its rotation forward in the direction of fire.

Description

The invention relates to automatic weapon feeding systems and can be used to feed a cartridge belt to the weapon receiver. A feed path for an automatic weapon is described in Russian Patent No. 2113673. It comprises a rotating frame with an outlet port, a movable and fixed sleeve, and a side guide. The fixed sleeve is equipped with guide grooves, while the movable sleeve is designed as a spring band attached to the rotating frame, the ends of which are installed in the guide grooves of the fixed sleeve. The disadvantage of the described design is the large force required to rotate the frame due to the friction of the movable sleeve in the guide grooves of the fixed sleeve and the small elevation angles of the weapon. This drawback is partially addressed in the design of the grenade launcher feed path described in Russian Patent No. 2222759, which we selected as our prototype. The feed path of the grenade launcher, mounted on the turret of a combat vehicle, contains a magazine with vertically mounted grenades connected by links forming a belt fed to the grenade launcher through a guide neck with rollers and a tube secured along the grenade launcher's axis of rotation. The described mechanism also includes a cradle with a spring-loaded slide, a lifting mechanism, and a magazine containing ammunition. The lifting mechanism is an electric drive with a retractable bayonet connected to the cradle via a shackle and a crossbar. The elevating mechanism, an electric drive with a retractable rod connected to the cradle via a clevis and crossbar, reduces the time it takes to vertically aim the weapon at the target. The grenade launcher's ammunition is stored in an armored magazine mounted on the turret, eliminating the possibility of damage to the grenades from bullets and shrapnel, and in the event of an ammunition explosion, it eliminates the risk of injury to the tank or infantry fighting vehicle crew. The vertical loading of the grenades in the magazine, and the feed of the belt to the grenade launcher through a guide neck with rollers and a tube fixed along the grenade launcher's axis of rotation, improves the loading of ammunition into the magazine and the feeding of the ammunition to the weapon. A drawback of the described grenade launcher feed path is the potential for delays in grenade launcher firing due to the belt's loose position in the tube in front of the grenade launcher's receiver. Belt links can become caught or misaligned relative to the grenade launcher's receiver. The objective of the claimed invention is to ensure the possibility of eliminating delays in the firing of a grenade launcher due to jamming of the belt with grenades in the feed path. This problem is solved by the design of the feed path for an automatic grenade launcher placed on the turret of a combat vehicle, which contains a magazine with vertically installed grenades connected by links that form a belt fed to the grenade launcher through a guide neck with rollers and a cylindrical tube secured to the magazine along the axis of rotation of the grenade launcher, while the new thing is that between the cylindrical tube and the receiving window of the grenade launcher a curved neck is placed in such a way that on the end of the cylindrical tube a cover with a rectangular window is overlapped, to which the end of the curved neck is welded, in addition, the receiving window of the grenade launcher is offset from the axis of its rotation forward in the direction of fire The proposed technical solution is explained by graphic materials - Fig. 1-3, where Fig. 1 shows a top view of the grenade launcher with the magazine cover removed, Fig. 2 shows a top view of the magazine, Fig. 3 shows a section along the roller axis with a view of the cover from the inside. Automatic grenade launcher 1 comprises magazine 2 with ammunition of vertically mounted grenades 3 connected by links 4 forming a belt. The belt with grenades is fed to grenade launcher 1 through guide neck 5 with rollers 6 and cylindrical tube 7. Guide neck 5 and cylindrical tube 7 are rigidly fixed to magazine 2. The axis of cylindrical tube 7 coincides with the axis of rotation of grenade launcher 1 in the vertical plane. Cover 9 is overlapped on cylindrical tube 7 and connected by means of curved neck 8 to the receiving window of grenade launcher 1. The receiving window of grenade launcher 1 is offset from its axis of rotation forward in the direction of firing. When the grenade launcher fires, the belt with grenades 3 moves from the magazine 2 through the guide neck 5 into the cylindrical tube 7. In this case, the belt with grenades 3 rolls along the rollers 6 and changes its direction. From the cylindrical tube 7, the belt is fed through the curved neck 8 to the receiving window of the grenade launcher 1. When the grenade launcher 1 rotates in the vertical plane around the horizontal axis, the curved neck 8 rotates together with the grenade launcher 1 and the cover 9 relative to t
