Description

Technical Field

[0001] The utility model belongs to the technical field of ammunition, and in particular relates to a projectile device with the dual functions of opening a cabin to scatter and ignite and ignite. Background Art

[0002] Training bullets usually use an internal smoke-generating device to replace the lethal unit in live ammunition, and are used instead of live ammunition for shooting drills and live-fire exercises, thereby eliminating safety hazards and improving the troops' actual combat capabilities.

[0003] Compared with the live-ammunition killing unit, the smoke-generating device itself does not have a fuze structure. It is necessary to use the mother bomb ejection device to ignite the smoke-generating device while the mother bomb is opened and scattered. Therefore, it is necessary to design a ejection device with the dual functions of open-bay ejection and ignition to achieve the open-bay ejection and synchronous ignition of the smoke-generating device, so as to achieve the effect of replacing live-fire shooting drills and live-fire exercises. Summary of the invention

[0004] The purpose of the utility model is to realize the function of opening the compartment and scattering the ammunition in the air and igniting the smoke generating device synchronously, so as to achieve the effect of actual troop exercise.

[0005] The technical solution adopted by the utility model to achieve its purpose is: a projectile device with the dual functions of opening the cabin for scattering and igniting, including: a push plate, a sealing ring, and a buffer pad; a sealing groove is opened on the outer circumference of the push plate, and the sealing ring is arranged at the sealing groove; the buffer pad is adhered to the rear end of the push plate; a circular array ignition channel is also arranged on the push plate, and the ignition channel runs through the push plate and the buffer pad.

[0006] Furthermore, the sealing groove has two layers.

[0007] Furthermore, the push plate is made of high-strength alloy steel.

[0008] Furthermore, the sealing ring adopts a rectangular structure.

[0009] Furthermore, the buffer pad is made of high-strength aviation rubber material.

[0010] The beneficial effects of the utility model are as follows: the push plate is made of high-strength alloy steel and is designed with a double-layer sealing groove and a circumferential array ignition channel. The double-layer sealing groove is used to install a sealing ring to achieve circumferential sealing of the inner cavity wall of the projectile; when the ignition cartridge is in action, the high-temperature and high-pressure gunpowder gas can ignite all the smoke-generating devices through the circumferential array ignition channel, and simultaneously open the bottom of the mother bomb, and then scatter the smoke-generating device through the push plate; the sealing ring adopts a rectangular structure and is installed in the circumferential double-layer sealing groove of the push plate to prevent the gunpowder gas from escaping along the inner cavity wall of the projectile; the buffer pad is attached to the rear end of the push plate and contacts the end face of the smoke-generating device, and is used to reduce the pressure shock to the smoke-generating device when the cabin is opened.

[0011] The working process of this utility model:

[0012] After the mother bomb ignition box is activated, the high-temperature and high-pressure gunpowder gas can ignite all the smoke-generating devices through the circular array ignition channel, simultaneously open the bottom of the mother bomb, and scatter the smoke-generating devices through the push plate.

[0013] Beneficial effects of the utility model:

[0014] ① Circumferential double-layer sealing technology realizes circumferential sealing of the inner wall of the projectile, preventing the gunpowder gas from escaping along the inner wall of the projectile, causing a decrease in ignition ability;

[0015] ② Array ignition channel design to achieve full coverage ignition capability for all smoke generating devices;

[0016] ③The cushion structure is designed with high-strength aviation rubber material to reduce the pressure impact on the smoke generating device when the cabin is opened. BRIEF DESCRIPTION OF THE DRAWINGS
