Abstract
The novel fire extinguishing bomb consists of primer, triggering explosive, propellant, partition, liquid CO2 and switch, and the bomb body is made of steel HP295 of thickness 2.75 mm and can ensure no leakage of CO2 and easy bursting out. CO2 heavier than air from burst fire extinguishing bomb will hold down fire fast. The present invention is suitable for use for extinguishing fire in places hard to reach, such as mountain top, cliff, etc. and may be used in battle.
Description
Big gun is learned principle to this invention of technical field and chemical content combines, and belongs to big gun and learn and chemical crossing domain.
The present big gun of background technology learns a skill ripe, chemistry has also developed into quite high level, both are combined produce beyond thought effect surely, the fire extinguisher bomb of usefulness has aircraft to throw at present, but there is not big gun to penetrate, so big gun is learned a skill for I and chemical knowledge combines, and have worked out novel big gun and have penetrated fire extinguisher bomb.
The purpose of summary of the invention invention is to solve mountain top, steep cliff, the difficult problem of putting out a fire from far-off regions that the people is difficult to arrive, it is in light weight that mortar has been brought into play in this invention, mobility is good, emission rate fast (30/minute), can cross over mountain after mountain, do not stay dual-purpose gun far firing range, firepower on the advantage at dead angle and howitzer, gun-howitzer, rocket gun, the warship violent, kill and wound the advantage that the explosion scope is good, elevation range is big, can effectively suppress the condition of a fire, personnel race against time for fire extinguishing.
This fire extinguisher bomb is that big gun is penetrated, and is made up of the fire in a stove before fuel is added, primer mixture, propellant powder, dividing plate, liquid carbon dioxide and switch.The fire in a stove before fuel is added, primer mixture, propellant powder are a part, and the centre separates with dividing plate, and switch is on bullet.Specific to rocket projectile, except that engine, identical with said structure.
The fire in a stove before fuel is added of fire extinguisher bomb, primer mixture, propellant powder follow former shell identical, guarantee the range of shell.
Ammunition and carbon dioxide liquid body and function dividing plate separate, because carbon dioxide liquid is not combustion-supporting, does not separate and can influence gunpowder fully burn, and then influence range, and block board thickness is 2.75mm.
The material that dividing plate adopts is a weldering bottle special-purpose steel, and code name HP295 guarantees that carbon dioxide liquid does not leak.Because powder burning can produce the high temperature of several Baidu, high temperature can make carbon dioxide liquid become gas rapidly, and shell case explodes because of bearing pressure, emits carbon dioxide, reaches the fire extinguishing purpose.Because the shell flying speed is fast, powder burning can just not produce the high temperature of several Baidu once, so fried thorax phenomenon can not take place.With 100 millimeters mortars of Chinese 1971 formulas is example, and this big gun initial velocity is 250 meter per seconds, 4700 meters of maximum ranges, if fly with the speed of 250 meter per seconds, reaching maximum range needs 18.8 seconds; With Chinese 1967 formulas, 82 mortars is example, 3032 meters of this big gun maximum ranges, and minimum initial velocity is 77 meter per seconds, with this speed flight, reaching maximum range needs more than 39 seconds; With 1954-2 formula 122mm carriage motor howitzers of China is example, and this big gun initial velocity is 515 meter per seconds, 11800 meters of maximum ranges, and with this speed flight, reaching maximum range needs 22.9 seconds; With Chinese 83 formula 152mm carriage motor howitzers is example, and this big gun initial velocity is 655 meter per seconds, 17230 meters of maximum ranges, and with this speed flight, reaching maximum range needs more than 26.3 seconds; With Chinese 1983 formula 273mm self-propelled rocket launchers is example, and this big gun initial velocity is 39 meter per seconds, 40000 meters of maximum ranges, and with this speed flight, reaching maximum range needed more than 1025.6 seconds, about more than 17 minutes.So Duan time, fried thorax is impossible, and above cannon type is older, and with minimum speed computing time, new gun reach is farther, and firing rate is faster, and fried thorax is also just more impossible.
Containing the part of carbon dioxide liquid, is exactly a steel cylinder of filling carbon dioxide liquid in fact, and carbon dioxide liquid obtains by pressurization.At normal temperatures, when being compressed to 75～80 kg/cm pressure, be in a liquid state, use the steel cylinder can.Why adopt liquid carbon dioxide? because liquid CO 2 quantity is big, do not produce so many carbon dioxide by reaction, and carbon dioxide is non-conductive, does not produce pollution, therefore adopt carbon dioxide.It is more than 99.5%, to be generally industry byproduct that carbon dioxide requires purity, easily obtains, price is also more cheap, use " dry ice " why not? because " dry ice " needs low temperature, pressurization, compression, the cost height, mobile poor, be difficult for preserving, cause delay easily when crucial, and carbon dioxide liquid obtains easily, cost is also low, therefore good fluidity is with compression arbon dioxide liquid and need not " dry ice ".
Warhead form is constant, and switch is on bullet.
Body adopts weldering bottle special-purpose steel, code name HP295, and thickness 2.75mm, this steel belongs to mild steel, because metal has good thermal conductivity, quick heating, and carbon is a kind of intensified element.Phosphorus content in the steel increases, and the intensity hardness of steel all increases, and the mild steel phosphorus content is low, and intensity and hardness are not high, thereby blast early easily when preheating, emit carbon dioxide, and cost is low, ability per jin money more than 3 yuan.
Carbon dioxide becomes gas by liquid, and volume will enlarge more than 1330 times.Compeling with 87 formulas 82 of Northern Industrial Company development is example, and this big gun shell weighs 4.2 kilograms, and with 2 kilograms of calculating of powder charge, if adorn 2 kilograms of carbon dioxide liquid, becoming behind the gas is exactly more than 1 cubic metre.The gas that relative aperture 82 urgent big mortar, rocket gun, gun-howitzer, howitzers produce can be more, because carbon dioxide is heavier than air, thereby can dissipation, fire to the unapproachable mountain top of people, steep cliff, remote districts has very strong suppression, can strive for valuable attack time for the fire extinguishing personnel.
This fire extinguisher bomb is applicable to the dual-purpose gun on mortar, howitzer, gun-howitzer, rocket gun, the large-scale naval vessels, is an invention therefore, multiple use.
Why make novel big gun penetrate fire extinguisher bomb, be because the fire extinguisher bomb that aircraft is delivered is identical with the bomb structure, and this fire extinguisher bomb does not have fuse, big gun is penetrated, the material that adopts is a weldering bottle special-purpose steel, code name HP295, and the heat that produces by powder burning makes liquid carbon dioxide become gas, burst body, resulting cost is low.
Add dividing plate when producing fire extinguisher bomb earlier, and then add propellant powder and ignition charge, then adorn the fire in a stove before fuel is added, at last liquid carbon dioxide is added in the body by bullet.
Forbid after this fire extinguisher bomb fills to collide, forbid burning sun to tan by the sun, inaccurate near thermal source and naked light.
Use aerial extinguishing, the cost of aircraft, fuel consume are more much bigger than the compacting cannon, aircraft value itself is minimum have hundreds of thousands, add with oil, pilot's training, expense will be very huge, and mortar, shoulder resists, packs and get final product, and action makes things convenient for, howitzer, the gun-howitzer several people of traction just can haul out, and the certain expense of vehicle-mounted cannon is also much lower than aircraft, and ground artillery for suppression firing rate is fast, far firing range, the precision height, emission is simple, cost is low, is desirable Fire extinguisher.
This fire extinguisher bomb of description of drawings is made up of the fire in a stove before fuel is added, primer mixture, propellant powder, dividing plate, liquid carbon dioxide, switch, the fire in a stove before fuel is added, primer mixture, propellant powder are a part, and liquid carbon dioxide is a part, and the centre separates with dividing plate, switch is on bullet, and airframe material is weldering bottle special-purpose steel.
Description of drawings Fig. 1 is a bullet, and Fig. 2 is impulse charge.
