Description

{Fuse or detonator improved reliability}

The present invention relates to a new pipe having improved detonation reliability, and more particularly, to a method of disposing a chemical product in parallel in a mechanical safety loading device mounted on a new pipe, Which is improved in reliability of detonation.

The new pipe is attached to ammunition or shells and operates at a suitable time to detonate the internal explosive. Depending on its function, it has a fast, delayed, timed, close-up, and controlled fuse. , Clock, radio wave, magnetism, sound, water pressure fuse, etc.

Among them, the impact fuse blown by the impact after the impact can be divided into a mechanical fuse and an electric fuse according to the impact detection method. The mechanical fuse physically transmits the impact force generated when the shell collides with the target or the ground, It is a fuse that ignites the primer and ignites it to detonate. The electric fuse incorporates a sensor inside the fuse and electrically clears the signal of the sensor by electrically processing the primer to ignite the primer.

Although the electric fuse can be applied in various ignition systems, the demand for the fuse is increasing. However, when the electronic equipment of the new pipe is abnormal, the stability can not be ensured. Therefore, the reliability of the device deteriorates greatly.

On the other hand, there is a disadvantage that the mechanical fuse can not be applied in various ignition methods, but it does not need the battery used in the electric fuse, is strong against external environment such as moisture, is easy to operate and store, and is still used actively.

On the other hand, the fuse is manufactured with a safe loading device in order to prevent misunderstanding after normal or immediately after the launch of the shell. Such safety loading device is used in the fuse attached to various ammunition, Prevents the ammunition from being burnt by preventing the ammunition from being buried and allows the ammunition to operate after it deviates from the safe distance from the point where the ammunition is fired so that a safety accident such as an explosion at a close distance can be prevented in advance.

Such a safety loading device is located between the initiator of the new pipe and the claimant packed in the shell so that the two are physically separated from each other and assembled to the new pipe to prevent misunderstandings in the normal times and after a certain time The safety loading device releases the physical shutdown state, aligning the explosion sequence between the initiator and the assisting device, allowing the bomb to explode.

Among them, the mechanical safety loading device moves the ignition tube at the non-aligned position to the explosion series to the alignment position to make the ignition condition. The rotor having the detonating tube is operated by the reverse inertia force and rotation force generated after the shell is fired, The device is physically disconnected to move the detonator to the alignment position. When the detonator tube is aligned with the explosion system, the explosion is caused by the explosion order of the new tube or by the explosion due to external shock or the like. At this time, the backward inertia force refers to the centrifugal force generated when the cannon is actuated on the fuselage with the acceleration of approximately tens of thousands of G at the same time as the cannon firing, and the rotational force is generated when the shell is passed through the steel wire in the barrel and rotated at several thousand rpm. These retraction inertia and rotational forces are the driving forces of the fuse and safety loading device.

However, such a fuse has a problem that when the fuse command or external impact is insufficient, it leads to the fuse blowing, and the shells and the like are left as unexploded. Specifically, when a shell falls on an obstacle or an inclined surface of an eye, a water surface, or a ground surface, there is a case in which the impact force is insufficient and it is unpleasant. When the shell falls to a target point, There is a problem that unburned carbon occurs.

These unexploded bombs cause not only the problem of not achieving the original goal of the shell but also the problem that the unexploded bombs happen accidentally and unexpectedly damage due to explosion.

When the shells are fired, the first explosive path constituted by the electric primer 200 causes explosion of the shells due to the command of the normal fuse, and the explosion does not occur due to the first explosive path When the function of the fuse is disabled, the inertial decanting means 300 operates due to the inertia force acting on the inside of the new canal when the shell is collided, thereby causing the second firing path to cause detonation, It is an invention for an improved fuse.

Once the shell is fired, the safety loading device 500 is actuated to align the first and second detonation paths as described above. Here, FIG. 1 shows a state in which the inertial decanting means 300 constituting the second detent path in the loaded state after the shooting of a cannon is not yet operated, FIG. 5 shows a state in which the inertial decanting means 300 constituting the second detent path And shows the state in which the decanting means 300 operates.

The inertial weight body 330 of the inertial decanting means 300 is positioned by the inertia spring 310 in close contact with the lid of the safety loading apparatus 500 and the inertial weight body 330 of the inertial decanting body 330 is positioned, The sunk bushing 360 is fixed to the sunk bushing 360 by the sunk fixture 340 which is in close contact with the flange of the sunk bushing 360. [

When the sunk needle 370 is fixed before the sunk, the sunk staring spring 320 is pressed by the upper end of the sunk 370.

As the inertial weight body 330 advances due to the inertial force generated by its own mass during the operation of the new pipe after the collision, the immobilizing fastener 340 is released to the immobilizing fastener releasing part 350, Is released.

 Then, after the inertia weight body 330 is advanced by the advancement of the inertial weight body 330 after the catching, when the engagement of the sinking needle 370 is released, the sinking spring 320, which is being pushed, is sprung with elastic force to retract the sinking needle 370, 370 are struck by the delayed gunpowder assembly 573.

The second connection pipe 440 connected under the delayed gunpowder assembly 573 is connected to the full width tube pipe 610 of the full width tube cup 610 of the full width tube portion 600, (620) also explodes.

As described above, since the fuse of the present invention has improved detonation reliability line, the fuse is installed in parallel with the electric primer and the inertia deceleration means operated by the inertia when collision, Even if the city hall loses its function, the remaining inertial sinking means can be activated to detonate the fuse, thereby raising the probability of ignition and lowering the failure rate of the ammunition.

In addition, since the detonation rate of the ammunition can be lowered, the detonation reliability of the present invention can be lowered, so that unburdened bombs can be accidentally met, thereby preventing injurious damage caused by explosion, thereby minimizing casualties.

The vapor deposition evaporation source having a clogging prevention structure according to an embodiment of the present invention is not limited to the construction and operation of the embodiments described above. The embodiments may be configured so that all or some of the embodiments may be selectively combined so that various modifications may be made.
