Description
Technical Field
The invention belongs to the technical field of civil fuzes, and particularly relates to a high-reliability artillery artificial hail-suppression rain-enhancement bomb time fuze.
Background
The small-caliber antiaircraft gun hail-suppression rain-enhancement bomb is used for artificial hail-suppression rain-enhancement operation in an air shooting mode. The rain enhancement and hail suppression mechanism is as follows: the hail-removing and rain-increasing bomb is launched into a cloud layer to explode, so that the cloud layer which is likely to produce hail is influenced, hail embryos cannot be developed into the hail, or small ice particles fall to the ground before becoming large hail, and the aim of removing the hail is fulfilled; through filling the explosive explosion in the projectile body, can produce the shock wave, influence or change the interior dynamics process of cloud, reach the effect that the big gun was sounded rain and is fallen, make the silver iodide catalyst of dress in the projectile body simultaneously and spread in the long-pending rain cloud layer by the detonation wave, produce a large amount of crystal nucleuses, make "rain cloud" or "hail cloud" conversion, reach the purpose of increasing the rain.
At present, Russia, America, Israel, Thailand and Western Europe are used for carrying out artificial rain enhancement operation abroad, and Russia is the large scale for carrying out artificial hail suppression operation. At present, no report of hail suppression and rain enhancement by using an artillery shooting artificial hail suppression and rain enhancement mode exists abroad.
At present, the safety problem of the domestic hail-suppression rain-increasing bomb is prominent and mainly appears as follows: the pellet is too large after being subjected to air explosion, and the pellet possibly injures people when falling; as civil products, the launching environment and the using environment of the hail-suppression rain-increasing bomb and the fuse thereof launched by the retired small-caliber antiaircraft gun are basically the same as those of military products, even more severe, but the design of the fuse thereof does not meet the relevant requirements of GJB373B-2019 fuse safety design criteria which must be met by the military fuse, and the explosion of the shot bore leads to gun destruction and even the frequent occurrence of accidents of human death; because of the large usage amount, the reliability performance level of the fuse action is limited, and the unexploded explosive casualty accidents caused by the misfire of the fuse almost exist year by year. Hail suppression and rain enhancement operation is disaster prevention and reduction behavior, and the economy is very important. Therefore, the technical key of the small-caliber antiaircraft hail-suppression rain-increase bomb fuze is as follows: improving safety and reducing cost. The safety improvement comprises the reduction of bomb fragments, the reduction of the misfire rate of the fuze, the prevention of the reignition after the ground is blown down in the air, the guarantee of the safety of the disposal of the fuze after the misfire, and the satisfaction of the related requirements (explosion-proof safety, redundancy insurance, delay relief, selection of safe conductive explosives, non-relief state guarantee, and the like) of GJB373B-2019 fuze safety design criteria.
In order to solve these technical key problems, domestic researchers have made many relevant studies. According to the artificial rainfall bomb fuze design disclosed in Chinese invention patent 200620001167.0, the air explosion time is prolonged by connecting 2-4 delay explosive disks in series, but the delay explosive disks and a fire transfer sequence mainly composed of the delay explosive disks do not have an isolation design and therefore cannot meet the requirement of explosion-proof safety. The black powder is filled in an explosion initiating pipe designed by the artificial rainfall bomb fuze disclosed by the Chinese invention patent 00201925.6, and the explosion initiating pipe is too safe, so that the sensitivity requirements of GJB373B-2019 on detonating powder guiding are not met, the designs all have the possibility of early firing accidents such as chamber explosion and the like due to the fact that the ignition mechanism does not ignite in the service processing and launching processes, and have great potential safety hazards. Although the chinese patent 200610095035.3 discloses a powder delay relief and a centrifugal fuse, the centrifugal fuse has only one centrifugal fuse mechanism, rather than two or more centrifugal fuses which are generally arranged in an axisymmetric manner. The centrifugal safety mechanism is difficult to independently fulfill the safety function, so that the requirement of redundant safety is not met, and the safety and reliability are difficult to meet. In addition, the fuse explosion-proof mechanism adopts a vertical disc rotor structure instead of a recognized triangular rotor structure, and the fuse explosion-proof mechanism can be accidentally relieved in a chamber under the condition that the safety explosive column is accidentally cracked after the gunpowder is delayed and relieved, so that the chamber explosion is caused. The artificial hail-suppression rain-increasing bomb described in the chinese invention patents 200820100586.9 and 201220363259.9 has performed relevant improvement around the safety of the fuse, but the slider isolation mechanism designed in 200820100586.9 is not provided with a redundant insurance and a delay relief mechanism, so that the insurance can be relieved in the chamber, and the explosion-suppression safety cannot completely meet the corresponding national military standard requirements, and the potential safety hazard is still not completely solved. 201220363259.9 adopts double ignition detonation channels to provide reliable action, but each ignition detonation channel is provided with no explosion-proof mechanism, so that great potential safety hazard exists. The structure of the Chinese patent 201610952063.6 is slightly complicated, and the production reproducibility of the applied powder and explosive tray timing structure is poor.
In summary, the general problems with the prior art are: the safety of the detonator of the antiaircraft hail-suppression rain-enhancement bomb is low, the reliability is poor, and the producibility is difficult to meet.
Disclosure of Invention
The invention aims to provide a high-reliability time fuse for an antiaircraft gun artificial hail suppression and rain enhancement bomb, which has higher reliability, better safety and strong production reproducibility.
The technical solution for realizing the purpose of the invention is as follows: a high-reliability artillery artificial hail-suppression rain-increasing bomb time detonator comprises a detonator body, a delay powder timing ignition mechanism, an electronic timing ignition mechanism, a ball rotor safety and safety-relief mechanism and a detonator, wherein the delay powder timing ignition mechanism is arranged at the front end of the detonator body, the electronic timing ignition mechanism, the ball rotor safety and safety-relief mechanism and the detonator are arranged in a body cavity of the detonator body, a sixth-order stepped hole is formed downwards from the top surface of the front end of the detonator body, and is respectively a first-order hole, a second-order hole, a third-order hole, a fourth-order hole, a fifth-order hole and a sixth-order hole from front to back, a cover plate is arranged in the first-order hole, the delay powder timing ignition mechanism is arranged in the second-order hole, the third-order hole is used as a fire transmission channel, a magnetic recoil generator is arranged in the fourth-order hole, the electronic timing ignition mechanism is arranged in the fifth-order hole, the ball rotor safety and safety-relief mechanism are adjacent to the electronic timing ignition mechanism and are arranged in the sixth-order hole, the detonator is also arranged in the sixth-relief mechanism, and the detonator is arranged in the detonator, and the detonator body front end of the ball rotor safety-relief mechanism is adjacent to the ball rotor safety-relief mechanism, the rear end is used as a fuse output end and is used for detonating the explosive charge of the artificial hail-suppression rain-enhancement bomb containing silver iodide. The delay powder timing ignition mechanism and the electronic timing ignition mechanism are mutually independent, redundant ignition is realized, and the reliability of the fuse action is improved.
Compared with the prior art, the invention has the following remarkable advantages:
(1) the reliability is higher: compared with the existing product, the delay powder timing ignition mechanism and the electronic timing ignition mechanism have two timing ignition mechanisms, and the two timing ignition mechanisms are independent from each other and can ignite the flame detonator, so that the redundant design of the fuze timing ignition function is realized, and the misfire rate is effectively reduced.
(2) The safety is better: compared with the existing product, the ball rotor is locked by the split ring, the safety pin and the centrifuge in a triple mode under the assembly condition, cannot rotate and is in a dislocation state, and therefore the explosion-proof safety of the fuse is guaranteed. After the safety and safety relief mechanism of the ball rotor is installed in the fuse body, the ball rotor can be prevented from being assembled into a safety relief state by adopting a mode of visual observation and poking inspection from a central hole at the tail part, and the phenomena of missing assembly, wrong assembly and 'dead pressing' of the ball rotor due to impurities, hard edges, burrs and other redundancies are prevented. The ball rotor can rotate in two directions, the axis of the detonating tube on the ball rotor can coincide with the axis of the fuze and the projectile after a certain time delay, and the time for the ball rotor to rotate can ensure that the ball rotor is relieved beyond the safety distance of the projectile, namely, the delayed relief (for example, the ball rotor is 15 m away from a muzzle when used for an antiaircraft with the diameter of 37 mm).
(3) The production reproducibility is strong: compared with the timing principle and structure of a gunpowder and explosive tray in the existing product, the timing of the gunpowder delay tube and the electronic timing are easier to ensure the stable quality and the production efficiency.
(4) The cost is lower: the structure is simple, and most parts are in a revolving body configuration, so that the processing and the inspection are convenient, and the cost is reduced.
The invention is described in further detail below with reference to the figures and the detailed description.

When the shot is shot, under the action of the recoil force, the safety pin 47 of the recoil safety mechanism recoils to cut the shear pin 48, and the first locking of the ball rotor is released; meanwhile, the firing pin 22 in the delay powder timing ignition mechanism sits backwards, the flange on the firing pin is cut off, the delay body 23 is punctured, and the delay body starts timing work. The magnetic core recoil led by the magnetic recoil motor shears the safety sheet 33, the magnetic recoil motor generates electricity, the electric energy is stored in an electronic timing ignition module 34 in the electronic timing ignition mechanism 3, and the timing is started. The projectile moves in the chamber to approach the muzzle, the overload of the recoil is gradually reduced, the centrifugal force generated by the high-speed rotation of the projectile overcomes the friction force generated by the recoil to throw the two petals of the split ring 46 away along the middle weak part, the centrifugal pin 45 also compresses the centrifugal spring 410 to be withdrawn outwards, and thus the ball rotor is released. After the projectile flies out of the muzzle, the ball rotor, i.e. the isolation ball 41 and the detonating tube 44 therein overcome the friction torque under the action of the centrifugal torque and gradually rotate forward under the participation of the gyro torque, the explosion sequence is aligned, the fuse is relieved, and the projectile is in a state of being fired. The projectile flies a safe distance corresponding to the time that the ball rotor is rotating, and the fuse achieves delayed arming (e.g., 15 m away from the muzzle for a 37 mm caliber antiaircraft gun). After a period of time, if the delay powder timing ignition mechanism 2 finishes working firstly, flame is output, the flame detonator 49 is ignited through the central fire transmission hole arranged on the magnetic core of the magnetic recoil motor 31, the flame detonator 49 ignites the detonating tube 44 on one side of the ball rotor 41, the detonating tube 44 ignites the detonating tube on the other side, then the detonating tube is ignited, and the detonating powder 54 ignites the projectile to finish the detonation work; if the electronic timing ignition mechanism 3 finishes working first, the electric ignition head can also output flame to ignite the flame detonator 49, and the subsequent detonating and detonating processes are the same as the above. As described above, the delay charge timing ignition mechanism 2 and the electronic timing ignition mechanism 3 are redundantly provided in parallel. Any one set of the explosive burns out, and the other set of the explosive is exploded. And if one set fails to ignite, the other set is used as a backup to finish the preset ignition. The two timing ignition mechanisms are all in ignition failure, and are events with small probability. According to experience, the probability of accidental failure of one path of ignition mechanism is estimated to be about 1%, and the probability of failure of both paths of ignition mechanisms is about 1% multiplied by 1% =0.01%, namely one ten thousandth. On the premise of ensuring the production quality, the failure rate of the fuse safety and safety relief mechanism and the fuse detonation sequence is almost 0, so that the failure rate of the fuse action is considered to be possibly controlled below one ten thousandth. Under the condition of detonator misfire, the unexploded pellet can fall to the ground at high speed to generate kinetic energy damage. The timing expectation values of the two timing ignition mechanisms are set to be 15 s or 9 s or 12 s (according to the order requirement). The delay powder timing ignition mechanism 2 has larger timing error which can reach +/-3 s. And the timing error of the electronic timing ignition mechanism 3 is smaller within +/-10 ms.
The fuze guide and explosion transfer medicine meets the sensitivity requirements of GJB373B-2019 'fuze safety design rule' on the guide and explosion transfer medicine, and can ensure that the accidental fire cannot be caused to cause premature explosion under the assembly condition, during the service treatment and in the launching process.
If the detonator accidentally misfires in the air, such as if the ball rotor safety and arming mechanism 4 is not armed or not fully armed (meaning that the ball rotors are not aligned or not fully aligned), the fired detonator 49 can still be initiated by the two-way timing ignition mechanism, but the detonator is in a self-disabling state, at which time the formed unexploded charge is safe. If the two timing ignition mechanisms of the fuze accidentally misfire in the air, but the safety and safety release mechanism 4 of the ball rotor is relieved, namely the ball rotor is aligned, at the moment, because the fuze does not have an instantaneous trigger mechanism, accidental ignition explosion cannot happen at the moment of landing. And in the process of falling to the ground, the structure of the detonator head can be damaged, and even if the detonator delay powder timing ignition mechanism 2 is not ignited before and is ignited when falling to the ground, the detonator delay powder timing ignition mechanism can also fail due to the damage of the head structure because of the existence of the delay action, the accidental ignition action can not occur any more, and the formed unexplosive powder is also safe.
