Description

A High Reliability Anti-aircraft Artillery Artificial Hail-suppressing Rain-enhancing Bullet Time Fuze

technical field

The invention belongs to the technical field of civilian fuzes, in particular to a high-reliability artificial hail-suppressing and rain-enhancing bullet time fuze for anti-aircraft guns.

Background technique

The small-caliber anti-aircraft artillery hail suppression and rain enhancement bullets are used for artificial hail suppression and rainfall enhancement in the form of air-to-air shooting. Its mechanism of increasing rain and hail is: launch the hail-suppressing bomb into the cloud layer and explode, exert influence on the cloud layer that may produce hail, so that the hail embryo cannot develop into hail or make the small ice particles fall to the cloud layer before they become large hail. ground to achieve the purpose of hail suppression; through the explosion of the explosives loaded in the body, shock waves can be generated, affecting or changing the dynamic process in the cloud, achieving the effect of cannons and rain, and at the same time, the silver iodide catalyst installed in the body is blown by the detonation wave Sowed in the cumulonimbus cloud layer, a large number of crystal nuclei are produced to transform the "rain cloud" or "hail cloud" to achieve the purpose of increasing rainfall.

At present, Russia, the United States, Israel, Thailand and many countries in Western Europe have carried out artificial rainfall enhancement operations abroad, and Russia has carried out artificial hail suppression operations on a large scale. At present, there is no report of using anti-aircraft guns to shoot artificial hail-preventing and rain-enhancing bombs to prevent hail and increase rainfall abroad.

At present, the safety problems of domestic anti-hail and rain-increasing bombs are prominent, mainly reflected in: the fragments of the projectile are too large after air-burst, and may hurt people when they fall; as civilian products, hail-proof and rain-increasing bombs currently fired by decommissioned small-caliber anti-aircraft guns The launch environment and use environment experienced by the fuze and its fuze are basically the same as those of military products, or even more harsh, but its fuze design does not meet the relevant requirements of GJB373B-2019 "Fuze Safety Design Guidelines" that military fuzes must meet. Due to the large amount of use, limited to the reliability performance level of the fuze function, accidents of unexploded ordnance casualties caused by fuze blind fire almost exist every year. Hail prevention and rainfall enhancement is an act of disaster prevention and mitigation, and its economy is very important. Therefore the technical key of the anti-hail and rain-increasing bomb fuze of the small-caliber anti-aircraft artillery is: improving safety and reducing cost. Among them, improving safety includes reducing projectile fragments, reducing the fuze misfiring rate, preventing refiring on the ground in the case of misfiring in the air, ensuring the safety of dud bomb disposal after misfiring and landing, and meeting the relevant requirements of GJB373B-2019 "Fuze Safety Design Guidelines" Requirements (explosion-proof safety, redundant insurance, delayed release of insurance, selection of safe guided explosives, guarantee of non-release insurance status, etc.).

In order to solve these key technical problems, domestic researchers have done a lot of related research. As described in Chinese Invention Patent 200620001167.0, the design of the artificial rainfall bomb fuze prolongs the air blast time by connecting 2-4 delayed drug discs in series, but these delayed drug discs and the fire transmission sequence mainly composed of them have no isolation design, so Does not meet the explosion-proof safety requirements. Chinese invention patent 00201925.6 describes the design of the artificial rainfall bomb fuze. The detonator contains black powder and Taian, neither of which meets the sensitivity requirements of guided explosives in GJB373B-2019. Ignition by the ignition mechanism results in early ignition, causing premature explosion accidents such as chamber explosion, which has a greater safety hazard. Although Chinese invention patent 200610095035.3 is provided with gunpowder delay release insurance and centrifugal insurance, its centrifugal insurance mechanism has only one, rather than two or more that are usually arranged symmetrically. It is difficult for the centrifugal insurance agency to perform insurance functions independently, so it does not meet the requirements of redundant insurance, and the safety and reliability are difficult to meet. In addition, the fuze explosion-proof mechanism adopts a vertical disk rotor structure instead of the recognized triangular rotor mechanism. In the case of delayed release of the gunpowder, the fuse may be accidentally released in the chamber and the chamber will explode if the powder column is accidentally broken. Chinese invention patents 200820100586.9 and 201220363259.9 describe artificial hail-suppression and rain-increasing bombs that have made related improvements around the safety of the fuze, but the slider isolation mechanism designed in 200820100586.9 is not equipped with redundant insurance and delayed release of the insurance mechanism, and it is possible to release the insurance in the bore , and the explosion-proof safety may not fully meet the requirements of the corresponding national military standards, and the safety hazards have not been completely resolved. And although 201220363259.9 has adopted double firing and detonating passages to provide reliable effect, there is no explosion-proof mechanism in every firing and detonating passages, so there is a very large potential safety hazard. The structure of Chinese patent 201610952063.6 is somewhat complicated, and the production reproducibility of the gunpowder powder disc timing structure applied is poor.

In a word, the common problems existing in the prior art are: the fuze of the anti-aircraft artillery hail-suppression and rain-increasing bomb has low safety, poor reliability, and difficulty in satisfying the manufacturability.

Contents of the invention

In the sixth-order hole, the front end is adjacent to the safety and release mechanism of the ball rotor, and the rear end is used as the fuze output end, which is used to detonate the explosive charge of the artificial hail-suppressing rain-enhancing bomb containing silver iodide. Among them, the delay charge timing firing mechanism and the electronic timing firing mechanism are independent of each other, so as to realize redundant firing and improve the reliability of fuze action.

Compared with the prior art, the present invention has the remarkable advantages of:

(1) Higher reliability: Compared with the existing products, it has two sets of timing firing mechanisms, a delayed charge timing firing mechanism and an electronic timing firing mechanism, and these two sets of timing firing mechanisms are independent of each other, and both can ignite the flame detonator. The redundant design of the fuze's timing fire function is realized, which effectively reduces the misfire rate.

(2) Better safety: Compared with the existing products, the ball rotor is triple-locked by the split ring, the safety pin and the centrifuge when assembled, so it cannot rotate and is in a misaligned state, thus ensuring the explosion-proof safety of the fuze. After the ball rotor safety and release mechanism is installed in the fuze body, it can be visually observed and checked from the center hole of the tail to prevent the assembly from being in the release state, and to prevent the ball rotor from being installed incorrectly, assembling errors, and due to impurities, hard The phenomenon that the ball rotor is "pressed to death" by redundant objects such as ribs and burrs. The ball rotor can rotate in both directions, and after a certain period of delay, the axis of the detonating tube on it can coincide with the axis of the fuze and the projectile. Delayed disarming (for example, 15 m away from the muzzle when used for 37 mm caliber anti-aircraft guns).

(3) Strong production reproducibility: Compared with the timing principle and structure of gunpowder discs in existing products, gunpowder delay tube timing and electronic timing are easier to ensure stable quality and production efficiency.

(4) Lower cost: the structure is simple, and most of the parts are in the shape of a rotary body, which is convenient for processing and inspection, and reduces the cost.

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

The ball rotor safety and disarming mechanism 4 includes a ball rotor composed of an isolation ball 41 and two nonel tubes 44, a ball cover 42 that accommodates the ball rotor and has an open rear end, and a ball cover 42 that closes the rear end opening. Ball seat 43, the flame detonator 49 positioned at the front end of the central axis of the ball cover, there is a cylindrical cavity between the upper surface of the flame detonator 49 and the lower surface of the safety plate 33, which is used to accommodate the magnetic core recoiled in the motor, the flame detonator 49 The lower surface is adjacent to the isolation ball 41, and there is a cylindrical hole between the flame detonator 49 and the isolation ball 41 on the spherical cover 42.

The split ring 46 of the ball seat 43 has a safety pin hole on the ball seat 43 on the other side, and a safety pin 47 is inserted in the safety pin hole. On one side of the ball seat 43, a shear hole is formed, the shear hole runs through the safety pin 47 to the ball seat 43, and the shear pin 48 is inserted, and the opening of the split ring 46 faces the safety pin 47.

The two sets of timing ignition mechanisms, i.e., the delay drug timing ignition mechanism 2 and the electronic timing ignition mechanism 3 are independent of each other, and their outputs can reliably ignite the flame detonator 49. The structures of the two sets of timing ignition mechanisms are connected in series and their functions are connected in parallel, which improves reliability. , which can meet the quantitative requirements of the ignition failure rate of less than one thousandth.

The working process of the artificial hail-suppressing and rain-increasing bullet time fuze of the present invention is as follows.

When assembled, the spacer ball 41 is locked by the safety pin 47, the split ring 46 and a pair of centrifuges 45, and cannot rotate and is in a dislocation state. At this time, even if the ball rotor is safe and the flame detonator 49 in the safety mechanism 4 is accidentally ignited and exploded, Due to the existence of the safety pin 47 and the isolation ball 41, the detonator 44 will not be detonated, and the detonator 5 will not be detonated, and the structure of the fuze body is complete, and no dangerous fragments fly out, thereby ensuring the flameproof safety of the fuze . After the ball rotor safety and disarming mechanism 4 is loaded into the fuze body, the mode of visual observation and toggling inspection can be taken from the tail center hole on the ball seat 43 to prevent it from being assembled into the disarming state, and to prevent the ball rotor from missing, Assembly errors and "crushing" of ball rotors due to excess material such as impurities, hard edges and burrs. In addition, the safety pin 47 is insured by the shear pin 48, the rotor 45 is insured by the corresponding centrifugal spring 410, the magnetic core of the magnetic recoil motor 31 is insured by the insurer 33, and the firing pin 22 is insured by the flange thereon. These insured parts (features) make the corresponding insured parts in the assembled state.

The drop shock, transport vibration and accidental rolling during service handling will not cause the shear pin 48 to be accidentally cut off, the split ring will not be accidentally thrown (opened), and the centrifuge 45 will not release the ball The rotor will not make the magnetic core of the magnetic recoil motor 31 cut off the safety piece 33, nor will the flange on the firing pin 22 be cut off. The safety pin 47, the split ring 46 and a pair of rotors 45 form a flameproof part Namely the redundant insurance of isolation ball 41. The isolation ball 41 is locked by the safety pin 47, the split ring 46 and the spinner 45, so it cannot be turned right and is in a misplaced flameproof state during assembly, ensuring the safety of the fuze in the service processing stage.

When the projectile is launched, under the action of the recoil force, the safety pin 47 of the recoil safety mechanism recoils, and the shear pin 48 is cut off to release the first lock of the ball rotor; The flange on it punctures the delay body 23, and the delay body has started timing work. The magnetic core that magnetic recoil motor leads recoils, and cuts safety sheet 33, and magnetic recoil motor generates electricity, and electric energy is stored in the electronic timing firing module 34 in electronic timing firing mechanism 3, and starts timing. The projectile moves in the bore and approaches the muzzle, and the recoil overload gradually decreases. The centrifugal force generated by the high-speed rotation of the projectile overcomes the friction force generated by the recoil, so that the two petals of the split ring 46 are thrown away along the weak part in the middle, and the centrifugal force 45 also compresses the centrifugal spring 410. withdraw, thereby freeing the ball rotor. After the projectile flies out of the muzzle, the ball rotor, that is, the isolation ball 41, together with the nonel tube 44 in it, overcomes the friction torque under the action of the centrifugal torque and gradually turns positive under the participation of the gyro torque. The explosion sequence is aligned, and the fuze is released. ready to go. Corresponding to the elapsed time of the above-mentioned turning of the ball rotor, the projectile flies over the safe distance, and the fuze realizes the delayed release of the insurance (for example, when it is used for a 37 mm caliber antiaircraft gun, it is 15 meters away from the muzzle). After a period of time, if the delayed drug timing firing mechanism 2 is finished earlier, it will output the flame, and ignite the flame detonator 49 through the set center fire transmission hole on the magnetic recoil motor 31 magnetic core, and the flame detonator 49 detonates the ball The nonel 44 on the rotor 41 side, the nonel 44 detonates the nonel on the other side again, then detonates the detonator, and the detonator 54 detonates the projectile, and completes the detonation work; After the work is finished, the electric ignition head will also output flame to ignite the flame detonator 49, and its follow-up detonation and detonation process are the same as above. As previously mentioned, the delayed medicine timing firing mechanism 2 and the electronic timing firing mechanism 3 are parallel redundantly arranged. If any of them caught fire, the other would be blown up. And one of them fails to fire, and then another set is used as a backup to complete the predetermined fire. It is a small probability event that both sets of timing firing mechanisms fail to fire. According to experience, the probability of accidental failure of one ignition mechanism is about 1%, and the probability of failure of both ignition mechanisms is about 1%×1%=0.01%, that is, one in ten thousand. Under the premise that the production quality is guaranteed, the failure rate of the fuze safety and release mechanism and the fuze transmission sequence is almost 0, so it can be considered that it is possible to control the fuze action failure rate below one ten thousandth. In the case of misfiring of the fuze, the unexploded projectile will fall to the ground at high speed and cause kinetic energy hazards. The timing expectations of the two sets of timing firing mechanisms are set to 15 s or 9 s or 12 s (according to order requirements). Among them, the timing error of the timing firing mechanism 2 of the delayed medicine is relatively large, and it is estimated that it can reach ± 3 s. And electronic timing firing mechanism 3 timing error is less, within ± 10 ms.

The guide and booster charges of the fuze meet the sensitivity requirements of the guide and booster charges in GJB373B-2019 "Fuze Safety Design Criteria", which can ensure that there will be no accidental ignition during assembly, service processing and launch, which will cause premature explosion. .

If the fuze accidentally misfires in the air, if the ball rotor safety and release mechanism 4 has not released the insurance or has not completely released the insurance (meaning that the ball rotor is not aligned or not fully aligned), then the flame detonator 49 can still be fired by two-way timing The mechanism triggers, but the fuze is in a self-deactivating state, and the resulting unexploded ordnance is safe. If the two timing firing mechanisms of the fuze accidentally misfire in the air, but the ball rotor safety and release safety mechanism 4 has been released, that is, the ball rotor has been aligned. At this time, because the fuze has no instant trigger mechanism, it will not happen at the moment of landing. Accidentally caught fire and exploded. And in the landing process, structural damage can take place in the fuze head, even if the fuze delay drug timing firing mechanism 2 does not fire before and fires when landing, because there is a time-delay effect, there is also failure because of the head structure damage, not Accidental detonation will again occur, at which point the resulting unexploded ordnance is also safe.
