Description

Technical Field

[0001] The utility model relates to the technical field of recoilless guns, in particular to a novel squad-used recoilless gun training bullet. Background Art

[0002] A nozzle-type recoilless gun is primarily composed of a barrel, a gun mount, and an aiming device. The barrel is equipped with a breech block and a nozzle. During firing, the gunpowder gas propels the projectile forward. The momentum of some of the gas (sometimes with added counterweights) ejected backward at high speed from the nozzle balances the momentum of the projectile and the forward-sprayed gas, resulting in no recoil in the barrel. Because the gun mount does not bear recoil during firing, there is no need for a recoil-recoil device. It simply serves as a support for the weight of the barrel and is rigidly connected to the barrel. Recoilless gun shells are primarily equipped with shaped charge armor-piercing shells and grenades. Directly using live ammunition for training with recoilless guns is expensive, and traditional training rounds are unlikely to meet the recoil requirements of recoilless guns. Therefore, a low-cost training round for recoilless guns is needed. Utility Model Content

[0003] To address the aforementioned issues, the present invention provides a new squad-use recoilless gun training round, characterized by comprising a mother round and a bullet. The mother round is shaped like a live recoilless gun round, with a launch tube extending through it along its central axis. A detachable primer seat is provided at the bottom of the mother round, on which a primer is mounted. The bullet is a small rocket mounted within the launch tube. The ignition device at the bottom of the bullet is connected to the primer on the mother round's primer seat via a detonating tube. When firing the training round, the firing pin inside the recoilless gun strikes the primer on the primer seat, igniting the rocket motor inside the bullet through the detonating tube, causing the bullet to be ejected from the launch tube.

[0004] Furthermore, the primer seat is arranged on the primer plug-in block, and a primer slot is provided at the bottom of the mother bullet for inserting the primer plug-in block.

[0005] Furthermore, a ball bolt is provided in the primer slot at the bottom of the mother bullet, and a groove for the ball bolt to be pressed into the side of the primer plug is provided. The ball bolt is pressed into the groove, thereby fixing the primer plug inserted into the primer slot.

[0006] Furthermore, the mother bomb includes a front shell, a rear shell and a wind cap, the top of the front shell is connected to the wind cap, and the bottom is connected to the rear shell.

[0007] Furthermore, a front support ring is provided in the front shell, and a rear support ring is provided in the rear shell; both ends of the launch tube are fixed in the inner rings of the front support ring and the rear support ring respectively.

[0008] Furthermore, a ball-bump bolt is provided at the rear end of the launch tube to fix the bullet in the launch tube.

[0009] In summary, the present invention has at least one of the following beneficial effects:

[0010] The purpose of this utility model is to provide a new squad-based recoilless gun training round. It utilizes a cluster-bomb design, with a launch tube installed inside the mother round. The small rocket projectile is connected to the primer seat at the bottom of the mother round via a detonating tube. This integrated cluster-bomb structure closely resembles the appearance and weight of a live round. When firing the training round, the firing pin inside the recoilless gun strikes the primer, igniting the bullet through the detonating tube, ejecting the bullet from the launch tube. After the mother round is removed, a new primer seat and bullet are replaced, allowing the mother round casing to be reused multiple times. This utility model's recoilless gun training round can be used for shooting training prior to live-fire exercises with the new squad-based recoilless gun, reducing live ammunition consumption and alleviating troop anxiety during training.

[0020] The following is combined with Figure 1-7 The utility model is described in further detail.

[0021] Example 1:

[0022] This embodiment discloses a new type of squad-use recoilless gun training round. The training round has a cluster structure. The mother round 1 is shaped like a live recoilless gun round, with a front shell 11, a rear shell 12, and a wind cap 13 from top to bottom. A launch tube 3 is provided along the central axis of the mother round 1, extending through it. A front support ring 14 is provided within the front shell 11, and a rear support ring 15 is provided within the rear shell 12. The ends of the launch tube 3 are fixed to the inner holes of the front support ring 14 and the rear support ring 15, respectively. A primer slot 7 is provided in the rear shell 12, and a removable primer block 6 is disposed within the primer slot 7. The primer block 6 is provided with a primer seat 4 for securing the primer. The primer seat 4 is provided with a primer, which is positioned identically to the primer position of a conventional recoilless gun round. The training round 2 is a small rocket, its igniter connected to the primer 4 of the mother round 1 via a detonating tube 5. When firing the training round, the firing pin inside the recoilless gun strikes the primer 4, igniting the igniter of the round 2 through the detonating tube 5. The igniter ignites the rocket motor, causing the round 2 to be ejected from the launch tube 3. After the round 2 is ejected, the primer insert 6 is removed, the next round 2 is loaded, and the primer insert 6 connected to the new round 2 is inserted into the primer slot 7, and the next artillery firing training can be carried out.

[0023] In order to ensure that the firing pin inside the recoilless gun can accurately strike the primer seat 4, the primer insert 6 needs to be fixed in the primer slot 7 of the primer insert 6. In this embodiment, a positioning ball bolt 8 is provided in the primer slot 7, and a groove for the positioning ball bolt 8 to be pressed into the side of the primer insert 6. The ball bolt 8 presses into the groove to fix the primer insert 6 inserted into the primer slot 7. The above-mentioned ball bolt fixing method is also applied to the bullet 2 in the launch tube of the mother bullet 1 in this embodiment, as shown in FIG. Figure 6 As shown, a pair of second ball-bumping bolts 9 are provided at the bottom end of the launch tube 3 , and an annular groove cooperating with the second ball-bumping bolts 9 is provided at the bottom of the bullet 2 for fixing the bullet 2 .

[0024] The purpose of this utility model is to provide a new structural design for a squad-use recoilless gun training bullet cluster. A launch tube is provided inside the cluster, and a small rocket bullet is connected to a primer seat at the bottom of the cluster via a detonating tube. The cluster has an overall appearance and weight similar to that of a live round. When the recoilless gun fires a training round, the internal firing pin strikes the primer, igniting the bullet through the detonating tube, causing the bullet to be ejected from the launch tube. After the cluster is removed, a new primer seat and bullet are replaced, allowing the cluster to be recycled multiple times. The recoilless gun training round proposed in this utility model can be used for shooting training prior to live-fire shooting with the new squad-use recoilless gun, reducing live ammunition consumption and improving the cost-effectiveness of training.

[0025] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
