Description

Technical Field

[0001] This utility model relates to the field of ammunition testing technology, specifically a simple gas-assisted light suppression test device. Background Technology

[0002] The terminal effect of ammunition refers to the damage to the target's structure and function caused by the ammunition's interaction with the target at the end of its flight. Depending on the type, the interaction between ammunition and the target varies significantly. High-explosive fragmentation projectiles interact with the target through the high-temperature, high-pressure gas and fragments generated by the explosive detonation. Penetrating projectiles penetrate the target using their own kinetic energy. High-explosive anti-tank projectiles crush the shaped charge liner to form a high-speed jet that penetrates hard-armored targets. Armor-piercing projectiles penetrate armored targets using the projectile's own kinetic energy. Different interaction methods between ammunition and targets require different testing methods and devices. Ammunition that utilizes kinetic energy to interact with the target is collectively referred to as kinetic energy body, including but not limited to fragments, penetrating projectiles, armor-piercing projectiles, and high-explosive anti-tank projectiles. When these projectiles interact with metallic targets, the high temperature and pressure during the process generate intense light and heat. Currently, high-speed cameras are commonly used in ammunition testing devices to capture the interaction process between kinetic energy bodies and targets. However, the flashes during the interaction process can prevent high-speed cameras from capturing the interaction process, thus severely limiting the functionality of high-speed cameras and leading to incomplete test results. Currently, there is no effective testing method or device that can effectively reduce the impact of flash, which has become an urgent problem to be solved in ammunition testing.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a simple gas-assisted light suppression test device, comprising a transmitting device, a kinetic energy body, a high-speed camera, and a light suppression component. The transmitting device is provided with a light suppression component in the direction of emission. The transmitting device can emit the kinetic energy body. A high-speed camera is arranged on one side of the light suppression component.

[0005] Preferably, the light-suppressing assembly includes a front airbag, a rear airbag, a target plate, a non-combustion-supporting gas, a target frame, a base frame, a front airbag frame, a rear airbag frame, and a tension strap. The target frame is fixedly connected to the top of the base frame, the target plate is threadedly connected to one side of the target frame, the front airbag is bonded to the front side of the target plate, the rear airbag is bonded to the rear side of the target plate, the front airbag frame is fixedly connected to the front side of the base frame, the rear airbag frame is fixedly connected to the rear side of the base frame, and the tension strap is sleeved on the outer end faces of the front and rear airbag frames.

[0006] Preferably, the base frame is provided in two sets, and the base frame is distributed at both ends of the bottom of the target frame.

[0007] Preferably, the gas inside the front and rear airbags is composed of non-combustible gas, including but not limited to nitrogen, argon, helium and carbon dioxide.

[0009] Preferably, the tightening straps are provided in two sets, and the tightening straps are distributed at intervals at the upper and lower ends of the front airbag frame and the rear airbag frame.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention achieves flame suppression and precise experimental observation through the release of non-combustible gases from the front and rear airbags. When the kinetic energy body impacts the target plate, the front and rear airbags rupture, releasing non-combustible gases such as nitrogen and carbon dioxide, forming a double isolation layer that effectively isolates oxygen and inhibits oxidation reactions, reducing flame generation by more than 90%. This gas-solid coupling protection not only covers the entire impact process but also absorbs some heat energy through gas expansion, effectively reducing the surface temperature of the target plate. Combined with a high-speed camera layout on the parallel surface of the target plate, the impact dynamics can be clearly recorded, providing data support for reconstructing the trajectory of the kinetic energy body.

[0012] The device adopts a modular design, based on a combination of an "F"-shaped steel frame and a tightening strap, which allows for rapid replacement of the airbag in a short time, facilitating quick experimental responses. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 The present invention provides an embodiment of a simple gas-assisted light suppression test device, comprising a transmitting device 1, a kinetic energy body 2, a high-speed camera 3, and a light suppression component 4, characterized in that: the transmitting device 1 is provided with a light suppression component 4 in the transmitting direction, the transmitting device 1 can emit the kinetic energy body 2, and a high-speed camera 3 is arranged on one side of the light suppression component 4.

[0023] Furthermore, the light suppression component 4 includes a front airbag 401, a rear airbag 402, a target plate 403, a non-combustion-supporting gas 404, a target frame 405, a base frame 406, a front airbag frame 407, a rear airbag frame 408, and a tension strap 409. The target frame 405 is fixedly connected to the top of the base frame 406. The target plate 403 is threadedly connected to one side of the target frame 405. The front airbag 401 is bonded to the front side of the target plate 403, and the rear airbag 402 is bonded to the rear side of the target plate 403. The front airbag frame 407 is fixedly connected to the front side of the base frame 406, and the rear airbag frame 408 is fixedly connected to the rear side of the base frame 406. The tension strap 409 is sleeved on the outer end face of the front airbag frame 407 and the rear airbag frame 408.

[0024] Furthermore, the base frame 406 is provided in two sets, which are distributed at both ends of the bottom of the target frame 405.

[0025] Furthermore, the gases inside the front airbag 401 and the rear airbag 402 are composed of non-combustible gases 404, including but not limited to nitrogen, argon, helium, and carbon dioxide. The front airbag 401 and the rear airbag 402 are fixed and closely attached to the front and rear surfaces of the target plate 403 by the front airbag frame 407, the rear airbag frame 408, and the tightening strap 409. The front airbag 401 and the rear airbag 402 are selected according to the size of the target plate 403, and the front airbag 401 and the rear airbag 402 can completely cover the surface of the target plate 403. The injected gas is a non-combustible gas 404, including nitrogen, argon, helium, and carbon dioxide, which does not support combustion. When the kinetic energy body 2 punctures the front airbag 401 and the rear airbag 402 during the impact of the target plate 403 and releases the non-combustible gas in the front airbag 401 and the rear airbag 402, the non-combustible gas will isolate the surrounding air and suppress the generation of a large amount of sparks during the impact of the kinetic energy body 2 on the target plate 403.

[0026] Furthermore, both the front airbag frame 407 and the rear airbag frame 408 are composed of two sets of "F"-shaped steel frames and one set of "I"-shaped steel frames welded together.

[0027] Furthermore, the tension straps 409 are provided in two sets, which are distributed at intervals at the upper and lower ends of the front airbag frame 407 and the rear airbag frame 408. They can quickly fix the front airbag 401 and the rear airbag 402 and keep them close to the front and rear surfaces of the target plate 403, which can improve the efficiency of test preparation and allow for low-cost and high-efficiency deployment.

[0028] Working principle:

[0029] Select appropriate sizes for the front airbag 401 and rear airbag 402 according to the size of the target plate 403. Inject non-combustion-supporting gas 404 into the front airbag 401 and rear airbag 402 to form a certain thickness. The front airbag 401 and rear airbag 402 are placed on the front airbag frame 407 and rear airbag frame 408 respectively, and the front airbag 401 and rear airbag 402 are tightly attached to the front and rear of the target plate 403 with the tightening strap 409, so as to completely cover the surface of the target plate 403. The high-speed camera 3 is located on one side of the parallel plane of the target plate 403, and the launching device 1 is located in a direction perpendicular to the target plate 403. After the launching device 1 launches the kinetic energy body 2, the kinetic energy body 2 first passes through the front airbag 401 and impacts the target plate 403. The kinetic energy body 2 releases a large amount of heat as it penetrates the target plate 403, causing the front airbag 401 to rupture due to the heat. The non-combustible gas 404 inside expands due to the heat, isolating the oxygen in the air. During the impact process, the kinetic energy body 2 and the target plate 403 cannot undergo oxidation to produce light and heat. After the kinetic energy body 2 passes through the target plate 403, it comes into contact with the rear airbag 402. Similarly, the rear airbag 402 ruptures due to the heat, and the non-combustible gas 404 inside expands due to the heat, isolating the oxygen in the air. During the impact of the kinetic energy body 2 on the target plate 403, it cannot undergo oxidation to produce a spark. Since there is no spark or the spark is significantly reduced, the high-speed camera 3 can clearly record the interaction process between the kinetic energy body 2 and the target plate 403.

[0030] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
