This addresses the problem that existing explosion effect experiments struggle to determine the explosion location in advance and often remain at the static explosion stage, contradicting the motion-induced explosion conditions in real-world applications and leading to biased experimental results. Specifically, it includes a light gas cannon, a projectile assembly, and a target. The light gas cannon fires high-pressure gas to propel the projectile assembly. The projectile assembly is housed within the barrel of the light gas cannon and includes a sabot, a trigger mechanism, a pull-to-fire detonator, and the projectile itself, all housed within the sabot. The trigger mechanism is connected to the trigger wire of the pull-to-fire detonator. The pull-to-fire detonator is connected to one end of the projectile. The other end of the projectile faces the target. The target corresponds to the barrel of the light gas cannon, and its length along the high-pressure gas emission direction matches the length of the trigger wire, ensuring that the explosion location of the projectile is within the target.

Description

Technical Field

[0001] This invention relates to a device and method for simulating the motion-induced explosion effect, specifically to a device and method for simulating the motion-induced explosion effect based on a light gas gun loaded with a pull-out detonator. Background Technology

[0002] The penetration explosion effect refers to the damage caused to a target by the projectile's explosion after penetrating it. For striking deep underground targets, the penetration explosion effect is the most important form of damage inflicted by ground-penetrating equipment. Therefore, research on the penetration explosion effect is of paramount importance to the development of ground-penetrating equipment. However, the difficulty in determining the explosion location in advance for full-scale ground-penetrating equipment presents certain challenges to the study of the penetration explosion effect.

[0003] For laboratory simulations of penetration and explosion effects, the current mainstream approach treats penetration and explosion as two separate effects. First, a predetermined hole is created in the target through drilling or projectile penetration. Then, a cylindrical explosive charge is pre-embedded in the target and detonated, causing damage. However, in actual combat, full-size ground-penetrating weapons typically explode during dynamic penetration, and the phenomenon of penetration leading to a stationary explosion is extremely rare. Therefore, studying penetration and explosion as two independent effects has certain limitations.

[0004] Therefore, there is an urgent need to establish a laboratory simulation device and method for the penetration and explosion effect, so as to realize a refined study of the penetration and explosion effect of a target at a predetermined location. Summary of the Invention

[0005] The purpose of this invention is to provide a device and method for simulating the motion-induced explosion effect based on a light gas gun loaded with a pull-type detonator, in order to solve the technical problem that existing explosion effect experiments are difficult to determine the explosion location in advance and are still at the static explosion stage, which does not match the motion explosion situation in actual applications, resulting in biased experimental results.

[0006] To achieve the above objectives, the present invention provides a motion penetration explosion effect simulation device based on a light gas gun loaded with a pull-out detonator, which is characterized by including a light gas gun, a projectile assembly, and a target.

[0007] The light gas gun fires high-pressure gas to propel the projectile assembly outward;

[0008] The projectile assembly is housed inside the barrel of the light gas gun. The projectile assembly includes a sabot and a firing mechanism, a detonator, and the projectile itself, all housed within the sabot. When the sabot is fired outside the light gas gun, it disintegrates under the influence of a high-speed airflow. The firing mechanism is connected to the firing wire of the detonator. The detonator is connected to one end of the projectile. The other end of the projectile faces the target.

[0009] The target corresponds to the barrel of the light gas gun, and its length along the high-pressure gas ejection direction is greater than the length of the firing wire, so that the explosion position of the projectile is located inside the target.

[0010] Furthermore, the projectile body includes a cartridge case and an ammunition;

[0011] The cartridge case includes a cylindrical section and a conical section coaxially connected; the cylindrical section is used to load ammunition, and one end of the cylindrical section is connected to a detonator; the large end of the conical section is connected to the other end of the cylindrical section, and the small end faces the target.

[0012] Furthermore, the firing element is a circular baffle with a diameter larger than the outer diameter of the projectile; the firing wire of the detonator is connected to the middle of the circular baffle.

[0013] Furthermore, the sabot is a split structure, comprising at least two sabots;

[0014] Between the at least two bullet holders, there is a first mounting cavity for mounting the detonator and the bullet body and a second mounting cavity for mounting the circular baffle; the first mounting cavity is located on the side of the bullet holder closer to the target body; the second mounting cavity is located on the side of the bullet holder away from the target body, and the side of the second mounting cavity away from the target body is closed.

[0015] Furthermore, it also includes a camera unit;

[0016] The camera unit is used to capture images of ammunition explosions in order to obtain explosion data.

[0017] Furthermore, the ammunition is a TNT charge.

[0018] Furthermore, the circular baffle is made of metal.

[0019] Meanwhile, the present invention also provides a method for simulating the motion-induced explosion effect based on a light gas gun loaded with a pull-type detonator. The method employs the aforementioned simulation device for the motion-induced explosion effect based on a light gas gun loaded with a pull-type detonator, and its special feature is that it includes the following steps:

[0020] Step 1: The light gas gun fires high-pressure gas at the target;

[0021] Step 2: The projectile assembly is ejected from the barrel of the light gas gun under the action of high-pressure gas;

[0022] Step 3: The sabot loses the constraint of the gun barrel and disintegrates under the action of the high-speed airflow, deviating from the trajectory. The charging fuse, detonator, and projectile continue to move toward the target. When the projectile reaches the target, it penetrates the target. The detonator enters the target along with the projectile, while the charging fuse is blocked outside the target. This causes the charging fuse to gradually pull the charging fuse of the detonator until the detonator is activated, and the projectile detonates inside the target.

[0023] The beneficial effects of this invention are:

[0024] 1. The motion-induced explosion effect simulation device of the present invention is equipped with a light gas cannon and a target. The light gas cannon can control the initial velocity of the projectile assembly. By adjusting the length of the firing wire, the explosion position of the projectile can be determined in advance, which is convenient for the study of the explosion effect.

[0025] 2. The motion-induced explosion effect simulation device of the present invention is equipped with a triggering element for the projectile and connects the triggering element to the triggering wire of the detonator. When the projectile penetrates the target, the triggering element can activate the detonator to detonate the projectile, causing the projectile to explode in the target, thereby realizing the motion-induced explosion process and improving the accuracy of the experimental results.

[0026] 3. In this invention, the firing element is set as a circular baffle with a diameter larger than the outer diameter of the projectile. When the projectile penetrates the target, the circular baffle is blocked outside the target due to the resistance of the target. As the projectile continues to move into the target, the firing wire is pulled open until the detonator is activated and the projectile is ignited, which further increases the convenience of the experiment.

[0027] 4. The present invention sets the head of the cartridge case as a conical section to reduce the pressure of the projectile penetrating the target, making it easier for the projectile to penetrate the target. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] A motion-induced explosion effect simulation device based on a light gas gun loaded with a pull-type detonator, such as Figure 1 As shown, it includes a light air gun 1, a projectile assembly disposed inside the barrel of the light air gun 1, and a target 2 disposed outside the barrel of the light air gun 1, and also includes a camera unit; the projectile assembly includes a sabot 3 and a firing pin 4, a detonator 5 and a projectile 6 disposed inside the sabot 3.

[0035] The light gas cannon 1 is used to fire high-pressure gas to propel the projectile assembly out of the barrel; the trigger 4 is a circular baffle with a diameter larger than the outer diameter of the projectile 6, and the circular baffle is made of a metal material that is not easily deformed; the trigger wire of the trigger detonator 5 is connected to the middle of the circular baffle, and the front end of the trigger detonator 5 is connected to the rear end of the projectile 6, and can be inserted into the projectile 6. The trigger detonator 5 is used to detonate the projectile 6; the front end of the projectile 6 faces the target 2; the target 2 corresponds to the barrel of the light gas cannon 1, and its length along the high-pressure gas emission direction matches the length of the trigger wire, so that the explosion position of the projectile 6 is located inside the target 2.

[0036] like Figure 2 As shown, the sabot 3 includes two sub-sabots 31; between the two sub-sabots 31 is a first mounting cavity 32 for mounting the detonator 5 and the projectile 6, and a second mounting cavity 33 for mounting a circular baffle; the first mounting cavity 32 is located on the side of the sabot 31 closest to the target 2; the second mounting cavity 33 is located in the middle of the sabot 31, and the side of the second mounting cavity 33 away from the target 2 is closed. The ammunition 62 is a TNT charge, cylindrical in shape, and detonates at the rear end. The sabot 3 is used to house the charging pin 4, the detonator 5, and the projectile 6, and is adapted to the caliber of the light gas gun 1. To accommodate the shape of the detonator and the projectile, and to achieve concentricity with the gun barrel, the sabot 3 adopts a split structure. When the sabot 3 moves inside the light gas gun 1, it is a single unit. When the sabot 3 is driven outside the light gas gun 1, the unrestrained sabot 3 disintegrates into two sub-sabots 31 under the action of the high-speed airflow and deviates from the trajectory.

[0037] like Figure 3 As shown, the projectile body 6 includes a cartridge case 61 and an ammunition 62; the cartridge case 61 includes a cylindrical section 611 and a conical section 612 coaxially connected; the cylindrical section 611 is used to load the ammunition 62; the large end of the conical section 612 is connected to the cylindrical section 611, and the small end faces the target body 2.

[0038] The camera unit is used to capture footage of the explosion of ammunition type 62 in order to obtain explosion data.

[0039] The laboratory simulation method for the motion-induced detonation effect based on a light gas cannon-loaded detonator proposed in this invention involves installing a trigger 4 outside the detonator. The light gas cannon 1 fires a projectile 6 that penetrates a target 2. When the projectile 6 reaches a specific position after penetrating the target 2, the trigger 4 is blocked outside the target 2, driving the trigger wire. The trigger wire is pulled out of the detonator 5, activating the detonator 5 to detonate the projectile 62, thus generating a motion-induced detonation effect. Specifically, the method includes the following steps:

[0040] Step 1: Light gas cannon 1 fires high-pressure gas at target 2;

[0041] Step 2: The projectile assembly is ejected from the barrel of the light gas gun 1 under the action of high-pressure gas;

[0042] Step 3: The sabot 32, freed from the barrel's constraint, disintegrates into two projectile sabots 31 under the influence of the high-speed airflow and deviates from its trajectory. The firing pin 4, the detonator 5, and the projectile 6 continue to move towards the target 2 along the initial velocity direction. When the projectile 6 reaches the target 2, it penetrates the target 2. The detonator 5 enters the target 2 along with the projectile 6, forming a circular hole slightly larger than the outer diameter of the projectile 6 inside the target 2. The firing pin 4, due to its larger diameter, is blocked outside the target 2. At this time, the firing pin 4 gradually pulls the firing wire of the detonator 5. When the distance between the firing pin 4 and the tail of the projectile 6 is greater than the length of the firing wire, the firing wire is pulled out of the detonator 5, and the detonator 5 is activated. The projectile 6 then detonates, producing a motion-induced explosion effect in the target 2. By adjusting the length of the firing wire, motion-induced explosion effects with different penetration distances can be achieved.

[0043] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present invention should be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
