Abstract
The invention relates to an anti-terrorist differential control method for exploding barriers, belonging to the field of anti-terrorist techniques. When anti-terrorist personnel rescue hostages and chase terrorists, the anti-terrorist personnel are often blocked by limited spaces or firm buildings, thus the anti-terrorist personnel need to break doors, walls, roofs and the like to open up fast channels, thereby winning the opportune time; and meanwhile, because the anti-terrorist personnel combat closely to the terrorists, the personal safety of the anti-terrorist personnel needs to be considered, and especially, the injury to the anti-terrorist personnel caused by explosive air shock waves needs to be considered. The invention is characterized in that concentrated charge is dispersed into multi-point charge, and differential delay ignition is carried out among points. The invention has the advantages of quickly exploding barriers and simultaneously lowering the strength of explosive shock waves in the same distance, thereby reducing the influence on the safety of the anti-terrorist personnel.
Description
Technical field
The invention belongs to the anti-terrorism technical field, relate to anti-terrorism and abolish the barrier method, specially refer to a kind of anti-terrorist differential control method for exploding barriers.
Background technology
The terrorist usually implements the violence activity in densely populated place, and to seize the hostage on both sides by the arms as undue influence.The anti-terrorism officer is when carrying out hostage's rescue and hunting for the terrorists, usually stopped by limited space or firm building, need broken opening door body, body of wall, roof system to open up express passway, thereby strive for the opportune time, simultaneously because the anti-terrorism officer is short range operations, its personal safety must to be considered, the injury problem of air-shock wave of especially exploding to the anti-terrorism officer.
Research and development have widely been carried out in anti-terrorism on the instrument of forcing open the door, forcing open the door in operation mainly is divided into bump, cutting, extruding and four kinds of methods of explosion.Invented a lot of instruments according to these four kinds of method people, as: the vertebra of forcing open the door, Fuse Type cutter, hydraulic clipper, the rifle of forcing open the door, the bloated door of a hydraulic pressure device, the bullet of forcing open the door, cumulative door opener etc.Bump, cutting, the very heavy inconvenience of carrying of extrusion type instrument, for the door body of sturdy material and the destruction of body of wall certain limitation is arranged, and need the opposite house body to act on repeatedly just playing generally speaking to break effect, leave arms times easily like this to the terrorist.That explosion class instrument has is in light weight, volume is little, convenient and swift, energy big, the efficient advantages of higher can effectively be avoided other type tool defective.Use explosive instrument to force open the door and not only can moment blow door, and the huge sound that produces of explosion time can effectively frighten the ruffian the room in, its shock wave can also destroy that door is gone up and a hiding behind the door machine-operated trap.
Explosive instrument commonly used at present has 500 serial flexible breakthrough type explosives, cumulative door opener etc.The 500 serial flexibilities explosive of forcing open the door is divided into two kinds of the type of forcing open the door and broken locks, and the explosive coated outside the foam flexible pipe with superpower adhesive power, can be bonded at any body surface by arbitrary shape.The principle that cumulative is forced open the door is identical with high explosive anti-tank cartridge, and structure is also similar with it, also is that the inner surface at hollow explosive adds the layer of metal drug-shaped cover; The cumulative door opener is after detonating, and the metal drug-shaped cover of internal layer melts under the HTHP that explosive produces and to the motion of explosive bottom, forms the laminar metal jet of a HTHP, can directly destroy body of wall, aircraft bulkhead and metal door.
Though the method with blast is forced open the door effectively, also is a kind of means of forcing open the door of danger, the required dose of fried door need pass through strict calculating, otherwise just may be because dose too much brings unnecessary damages to the anti-terrorism officer.Blast mainly directly act as the master with shock wave to anti-terrorism officer's injury.From finding for the present Research of air-shock wave both at home and abroad, people have grasped the biological damage mechanism of air-shock wave safe distance, shock wave and have adopted the various programs effectively to have simulated shock wave propagation law in air, but research all is single-point or the multiple spot problem of detonating simultaneously.Orthodox explosive is as long as door just can be blown effectively in the appropriate location that is fixed on door with adhesive tape, and only normally used concentrated group explosive initiation power is too concentrated, may cause unnecessary damages to the anti-terrorism officer of short range operations.
Shock wave to anti-terrorism officer's lethal effect is: cause that angiorrhoxis makes subcutaneous or visceral hemorrhage; Breaking of internal organs, particularly organa parenchymatosum such as liver, spleen break and lungs are torn; Myofibrillar tearing.Domesticly the injury problem of human body has been done a large amount of research,, can provide the shock wave scope of each extent of injury correspondence according to the extent of injury of different positive pressure of shock wave values to human body about impacting intensity of wave.From various countries' shock wave superpressure to human injury's decision content as can be seen, the positive pressure of shock wave critical value to the human zero damage of generally acknowledging is 20kPa.In superpressure is under the 20kPa, and its safe distance is greater than the dispersion powder charge after detonating for concentrated charge, is unfavorable for short range operations anti-terrorism officer safety.The excessive superpressure that adopts the quick-fried method of elementary errors control can avoid big dose to produce.Its method is: guaranteeing under the enough prerequisites of integral energy, to concentrate explosive to be divided into several parts, thereby the coupling method by different detonators, the detonate method etc. of detonator length, High-precision Detonator time-delay, laser time-delay that changes are carried out the quick-fried purpose of abolishing barrier that reaches of elementary errors time-delay control, anti-terrorism officer for short range operations, guaranteeing to open up passage fast again under its safe prerequisite like this.
Summary of the invention
The technical problem to be solved in the present invention provides the quick-fried method of elementary errors control, abolish barrier (door, body of wall, roof system) fast thus in can reduce blast impulse intensity of wave under the same distance again and reduce security implication the anti-terrorism officer.
Technical scheme of the present invention is as follows:
Estimate total dose of abolishing its needs according to different barriers, determine safe distance according to anti-terrorism officer's combat radius, determine the single-point explosive payload according to safe distance, total dose is separated into the multiple spot powder charge, elementary errors time-delay is between points detonated.Distance is 20cm～200cm between points.Time delay interval is 5～100 milliseconds between points, and preferentially selecting time delay interval is 10～20 milliseconds.Consider anti-terrorism officer's short range operations, the single-point dose is controlled at 10～100 gram TNT in weight range.The elementary errors time-delay method can adopt the elongated degree method of detonator, the other nonel tube detonator of multistage method, the other electric cap method of multistage, the laser time-delay method or the like of detonating.What of spaced point can be adopted multiple spots such as 2,3,4,5,6.Explosive can be selected emulsion, ammonium nitrate-fuel oil mixture, TNT, hexogen, HMX etc.
Thereby effect of the present invention and benefit are can reduce blast impulse intensity of wave under the same distance again to reduce security implication to the anti-terrorism officer when abolishing barrier fast.
