Description

Electronic Delayed Self-Destruct Fuse of Submunition

The present invention relates to an electronic delayed self-explosion fuse for bullets that can automatically explode after a predetermined time elapses of the bombs that have fallen freely to the ground. The present invention relates to an electronic delayed self explosive fuse for self bombing, which is capable of self-detonation and incapacitating fuses using electric energy.

In general, bullets are transported through a vehicle such as a bullet or a rocket that is fired by an artillery on the ground and then released from the air to fall to the ground. At this time, the conveying body may or may not be rotated. Such ordinary bullets are filled with high explosives to explode the carcass inside, and a lower part is equipped with a penetrator for penetrating armor such as an armored car or a tank. It is used for dual purposes such as armor penetration.

These bullets fall to the ground as they are released into the atmosphere by the explosive pressure generated when the fired carrier reaches a predetermined airspace and the discharge charge inside the carrier explodes. At this time, the individual bombs are scattered in all directions by the inertia of the discharge, falling and exploding on the ground. To this end, the fuse is equipped with a fuse for detonating the high explosives, which is mostly a mechanical fuse that is exploded by the impact force generated when the bomb hits a target or the ground.

However, the above-described conventional jatan is not detonated because it does not get enough impact force at the moment of hitting the ground structure after being released from the air will not be exploded. In other words, when the jatan falls in a buffer zone such as forest, snow, desert, tree, etc., since the impact force is not sufficiently applied to the mechanical fuse, the mechanical fuse becomes inoperable and the high explosives cannot be detonated.

This incapacitating bomb will not only cause damage but also explode during friendly operations in the area, causing property damage. Therefore, most of the bullets are additionally equipped with a delayed fuse that self-detonates when the mechanical fuse does not work. This delay fuse is divided into a chemical delay self-explosion fuse that ignites the gunpowder in a mechanical fuse so that a self-destruction occurs after a certain time elapses, and an electronic delay self-explosion fuse that uses a power circuit, a charging circuit, and a timer to self-detonate. It is becoming.

On the other hand, as a means for solving the problem of incidence of the above-described charcoal, a technique for preventing the incidence of charcoal is invented and filed by the present applicant and registered Nos. 10-0306357 [Ref. 1] and 10-0416004 [Ref. 2].

[Ref. 1] is related to chemical delay delay self-explosion pipe, and detonates ignition gunpowder, delayed gunpowder, and connection gunpowder in sequence through the striking device (striker) using the rotational inertia force generated in the process of ejecting the shot. It explodes high explosives and neutralizes bullets. In addition, [Ref. 2] relates to an electronic delayed self-explosion tube, and includes a reserve battery which is a power element, an electric detonation tube, a timer circuit, a charging circuit, a resistance element, an electronic switch, a wind sensing device, and the like. It activates the reserve battery through the blow device operated by the inertia generated from the air or the air resistance generated during the falling process, and activates the printed circuit board composed of the above-mentioned parts, and explodes the electric explosion tube to disable the bullet. have.

As illustrated in FIG. 1 to FIG. 4, a conical penetrator 133 is mounted inside the main body 131, and the penetrator 130 including the chemically delayed detonation tube disclosed in Ref. 1 is a penetrator. The high explosive charge 132 is filled inside the main body 131 forming the upper part of the upper part 133, and the high explosive charge is provided in the housing 120 installed on the upper part of the main body 131 by a stud 121. The slide assembly 125 provided with the detonation tube 129 which explodes 132 is provided so that a horizontal movement is possible. In addition, the inlet screw 127 is inserted into the housing 120 to restrain the slide assembly 125, and the sinking screw 123 to operate the detonator tube 129, and to be unfolded when released from the conveying member. The tape-shaped tape 135 to raise the sunk screw 123, the stiffener 136 to wrap the tape 135 is not expanded, and the safety pin 139 is provided.

The slide assembly 125 is a self-destructing device, the delay pipe assembly is filled with the ignition gunpowder, the delayed gunpowder and the connection gunpowder, and the delay tube assembly using the rotational inertia force generated during the ejection of the chattan 130. The striker 140 which is a strike device which strikes 137 is provided.

When the high explosives 132 are exploded, the conventional jatan 130 kills the blast as the main body fragments, and at the same time, penetrates the gloves by the principle of the molding peony where the explosive force is concentrated by the penetrator 133. do. In addition, when the set time is elapsed in the case where the chatan 130 falls into the buffer zone, the chatan 130 is detonated by the self exploding means.

However, the conventional self-destructing devices of the jatan have the following problems.

The chemically delayed self-expanding fusible tube disclosed in [Ref. 1] is a rotational inertia force generated when the shotgun 130 is discharged from the conveying body in which the triker 135 hitting the delay tube assembly 137 rotates at high speed. Since the operation is performed by using a low speed conveying body or a non-rotating conveying body 130, the striker 140 may not obtain a rotational inertia force that may detonate the delay tube assembly 137, which is an auxiliary detonating tube. have.

In addition, the delay tube assembly 137 assembled to the slide assembly 125 is a component that determines a set time that allows the bullets 130 to self-destruct, the set time is the length of the delay tube assembly 137 Is proportional to However, since the delay tube assembly 137 should be disposed in the same straight line on one side of the slide assembly 125, the delay tube assembly 137 cannot be longer than the length of the slide assembly 125. have. Therefore, there is a limit in the setting time for the bomb bomb 130 to self-destruct, and as a result, the altitude emitted from the carrier 130 is limited to within the bomb width setting time.

In addition, the electronic delayed self-expanding tube disclosed in [Reference 2] uses a reserve battery as a power supply element, and therefore an activation device for activating the reserve battery is necessary. Since the activation device occupies a lot of space of the slide assembly, the space cannot be used efficiently, and if the activation device is not properly operated, the self-exploitation function can not be achieved, thereby increasing the incidence rate.

[Reference 2] Registered Patent 10-0416004 (Park Soon-Jun et al.) 2004.01.09

On the other hand, the chatan 30, the main body 31 is provided with a high explosives (31a) and a penetrator (31b) therein; A housing (32) fixedly installed on an upper portion of the main body (31) by at least one stud (32c); A detonator tube 33 for exploding the high explosive powder 31a, the printed circuit board 10, and a self-exploding actuator are installed inside the slide assembly 35 which is elastically installed to allow horizontal movement in the housing 32. )Wow; A loading spring (34) installed in the housing (32) to elastically support the slide assembly (35); An inertial weight (37) having a predetermined weight and inserted into and coupled to a recess groove formed in the slide assembly (35); A sinking screw (36) which is screwed to the inertial weight (37) to protrude to the upper portion of the housing (32) and ascends when the shell (30) is discharged to start the self-exploding actuator; It includes; a safety pin (not shown) to block the operation of the power switch 21 so that power is not applied to the electrical circuit of the printed circuit board 10 during the assembly operation, and includes the housing 32 and the slide assembly 35 ) Is a safety pin insertion hole (not shown) through which the safety pin is inserted.

In addition, the self-destructing operation unit, the power switch 21 is elastically supported by the power spring 22, the power switch 21 in contact with the power terminal 17 to electrically connect the thin film battery 11 and the charging unit 12; Switch support pin 23 which is operated by the sinking screw 36 and restrains the power switch 21; Here, the sinking screw 36 is assembled to a tape 38 or parachute which is subjected to air resistance when the shell 30 is discharged from the air, and as the tape 38 or parachute (not shown) is released, It is rotated counterclockwise to release the restraint of the slide assembly 35. The tape 38 is fixed at both ends in a folded state on the upper part of the sinking screw 36, and is released when the jatan 30 is released from the air and the stiffener (not shown) is released by the discharge pressure. The sinking screw 36 is rotated. In addition, the switch support pin 23 is mounted to the sinking screw 36 via a stop ring 24. Of course, the switch support pin 23 and the sinking screw 36 may be integrally formed.

In addition, in the electric circuit of the printed circuit board 10, the shunt terminal 18, which was connected when the switch support pin 23 is moved upward, is opened to open the electric detonator tube 15. It is configured to be.

The housing 32 includes a housing main body 32a on which the slide assembly 35 is installed, and a housing cover 32b seated on an upper surface of the main body 31 and coupled to the housing main body 32a. Include. In addition, the slide assembly 35 is coupled to an upper portion of the slide body 35a on which the printed circuit board 10 and the self-acting operation unit are installed, and the inertia weight 37 is inserted. A slide cover 35b having a perforated hole, and a holder 35c which is inserted and coupled to the lower portion of the slide body 35a and has a recessed groove into which the inertial weight 37 is inserted.

In addition, the bomb 30 performs the self-detonation function only in a loaded state in which the detonation tube 33 and the submerged screw 36 are on the same axis, and the detonation tube 33 and the submerged screw 36 are the same. In the unloaded state not placed on the shaft, the detonator tube 33 explodes by the electric detonator tube 15, thereby disabling the fuse function.

The electronic delayed self exploding fuse for bombs according to the present invention configured as described above is operated when the bombs do not explode due to the dropping in the buffer zone to explode the bombs.

Before the release of the bullets 30 embedded in the conveying body or in normal times, as shown in FIG. Maintain state. That is, the power supply unit 17 of the printed circuit board 10 is in an open state, and power is not supplied to the timer 13, as well as a shunt which is a means for preventing accidental operation of the electric detonator tube 15. The terminal 18 remains connected, so that the self-expanding tube does not operate.

On the other hand, the shells 30 embedded in the conveying body are released from the conveying body at a predetermined position and fall to the ground, which was wrapped around the tape 38 by the ejection pressure when the charal 30 was ejected from the conveying body. The stiffener is separated and the folded tape 38 is unfolded. At this time, the tape 38 is rotated in the counterclockwise direction by the resistance to air, the sinking screw 36 fixed to the tape 38 is released from the inertial weight 37 of the inertial weight 37 Will move to the top.

When the sinking screw 36 is moved upward in the inertial weight 37, the switch support pin 23 assembled to the sinking screw 36 moves upward to release the restraint of the power switch 21. do. Thereafter, the power switch 21 is moved by the elasticity of the power spring 22 to be in contact with the power terminal 17 of the printed circuit board 10.

Accordingly, as shown in FIG. 11, the electric energy of the thin film battery 11 is supplied to the electric circuit of the printed circuit board 10 so that the timer 13 starts to operate and the resistance element 14 is provided. Via the charging unit 12 is also charged with electrical energy. In addition, as the switch support pin 23 moves, the shunt terminal 18 connecting both ends of the electric detonation tube 15 is switched from an open state to the detonation of the electric detonation tube 15. It creates a condition.

In this state, the timer 13 counts a preset time, and when the count is completed, the electronic switch 16 of the printed circuit board 10 is turned on (see FIG. 12). Accordingly, the electric energy accumulated in the charging unit 12 is instantaneously supplied to the electric detonator tube 15. The electric detonation tube 15 is exploded by the electric energy supplied to the electric detonation tube 15 instantaneously, and the explosive force of the electric detonation tube 15 is transferred to the high explosives 31a of the chatan 30. It is delivered and the bullet 30 will also explode. In other words, the operation of the self-explosion fuse is completed together with the self-explosion of the chatan 30.

At this time, if the delay setting time of the timer 13 is longer than the time that the bullet bomb 30 is separated from the conveying body and falls on the ground, the timer (even if the bullet bomb 30 falls off the ground buffer zone and fails) After the delay setting time of 13), the bullet bomb 30 may be automatically exploded. Therefore, by setting the delay setting time of the timer 13 sufficiently long, the chatan 30 can be released from the conveying body at a higher altitude. Of course, the delay setting time of the timer 13 may be set to be shorter than the time when the chatan 30 is separated from the carrier and falls on the ground, so that the chatan 30 may explode in the air.

On the other hand, before the counting of the timer 13 is completed, if the chatan 30 falls on a solid ground or hits the structure, the detonating tube 33 inside the slide assembly 35 is the sinking screw 36. Exploded by) to explode the bomb 30.

Since the restraint of the slide assembly 35 is released as the sinking screw 36 rises, the slide assembly 35 is horizontally moved by a loading spring 34 so that the detonating pipe 33 and the sinking screw ( 36) is on the same axis. In this state, when the bomb 30 hits the ground or the structure, the detonation screw 36 operates the detonation tube 33 to explode the high explosives 31a of the bullet 30.

In this way, only the loaded state in which the detonation pipe 33 and the sinking screw 36 are placed on the same axis, the bullet bomb 30 performs a self-destructing function when it explodes or fails. That is, the sinking screw 36 is released from the slide assembly 35 to release the restraint of the slide assembly 35 and at the same time, the slide assembly 35 is connected to the housing by the restoring force of the loading spring 34. 32 is exploded only when it is horizontally moved to one side of the load 32).

In the case of the non-loading state in which the detonation tube 33 and the sinking screw 36 are not on the same axis, the explosion force of the detonation tube 33 is not transmitted to the high explosive powder 31a of the chatan 30. The bomb 30 does not explode, and only the detonator tube 33 explodes by the electric detonator tube 15, thereby disabling the function of the fuse. Therefore, in the non-loading state in which the slide assembly 35 is not horizontally moved, even when electrical energy is supplied to the electric circuit of the printed circuit board 10, the chatan 30 is not exploded, thereby assembling the chatan 30. The explosion can be prevented in the process.

Although the preferred embodiments of the present invention have been described above, the scope of the present invention is not limited to such specific embodiments, and those of ordinary skill in the art are appropriately within the scope described in the claims of the present invention.
