Abstract
The utility model relates to a 37 mm antiaircraft artillery artificial rain bomb whose bottom is provided with a bottom exhausting distance increasing device. The bottom exhausting distance increasing device is composed of a base screw, a distance increasing compound medicine post and an ignition tracer medicine post; armament gas ignites the ignition tracer medicine post during transmission, and the ignition tracer medicine post ignites the distance increasing compound medicine post; the bomb ejects the armament gas from the ejecting hole of the base screw of the bottom exhausting distance increasing device after the bomb leaves a cannon to decrease pressure in a low-pressure area generated at the bottom of the bomb during the flying to reduce the flying resistance of the bomb. The bomb obtains increased distance, and the quantity of increased distance reaches about 30 percent.
Description
The utility model relates to the range-extending technique of artificial rainfall rail-proof bomb.
China is vast in territory, takes place during natural calamities such as arid, hail, has a strong impact on industrial and agricultural production.Opposing arid at present, hail general using aircraft seeding dry ice or antiaircraft gun, rocket gun emission artificial rainfall rail-proof bomb are sowed silver iodide etc.Wherein the most generally use 37mm antiaircraft gun emission artificial rainfall rail-proof bomb.
Artificial rainfall rail-proof bomb action principle is, bullet is transmitted in " nimbus " or " hail cloud " layer, the catalyzer in explosion time is contained in bullet (silver iodide) is sowed in the clouds by detonation wave, produces a large amount of nucleus, " nimbus " or " hail cloud " transformed, reach the purpose of rainfall preventing hail.The nucleus that catalyzer produced is many more, and the rainfall preventing hail effect is good more.The size of catalyzer nucleation rate, main relevant at the height of explosion time with explosive charge, agi content and bullet.Relation between them is, the fried point high nucleation rate of highly healing is big more.This is that high highly more temperature is low more because in the atmosphere convection layer, and the low more nucleation rate of temperature is high more.In addition, firing altitude is high more, and is good more to the mobility of differing heights, the shooting of different azimuth cloud layer.Therefore improving the artificial rainfall of 37mm antiaircraft gun launches height, becomes and problem to be solved.The common way that 37mm antiaircraft gun artificial rainfall bullet improves range is to strengthen the emission dose, increases initial velocity.But be subjected to placing restrictions on of the specified gun pressure of cannon, surplus is very little, and increasing dose does not have leeway.
The purpose of this utility model is to employ new technology, and under the situation that does not change impulse charge, increases the artificial rainfall of 37mm antiaircraft gun and launches height.
The purpose of this utility model is achieved in that in the bullet bottom increases end exhaust extended-range device, interior dress increases Cheng Fuhe powder column (smooth combustion under low temperature, low pressure), powder gases is lighted and is increased the Cheng Fuhe powder column when emission, bullet is when flight, spiral shell spray orifice ejection powder gases at the bottom of the extended-range device, the low-pressure area pressure that produces in the bullet bottom when reducing projectile flight, thus flight resistance reduced, make bullet obtain increasing journey.
The concrete structure of utility model is provided by Figure of description.
The utility model by body (1), explosive column (2), increase Cheng Fuhe powder column (3), end spiral shell (4), lighting charge column (5), silver iodide (6) and fuse (7) and form.Exhaust extended-range device in the end is formed by increasing Cheng Fuhe powder column (3), igniting tracer post (5) and end spiral shell (4).Increasing the Cheng Fuhe powder column is tubular, bore area scribbles efficient igniting agent, the lighting charge column diameter is greater than increasing Cheng Fuhe powder column internal orifice dimension, it is positioned at the groove of the central upper portion that increases the Cheng Fuhe powder column, end swivel nut is contained in the bottom that increases the Cheng Fuhe powder column, end spiral shell is threaded with at the bottom of the bullet, and spiral shell bottom in the end is provided with spray orifice.Powder gases is lighted lighting charge column (5) when emission, and the flame of lighting charge column refires and increases the Cheng Fuhe powder column, is coated in the efficient igniting agent that increases Cheng Fuhe powder column bore area this moment and is lighted simultaneously, has strengthened igniting strength.The bullet bottom pressure using amount was from 2800KG/cm after shell went out big gun
2, moment is reduced to atmospheric pressure, burns away but increase the Cheng Fuhe powder column, and powder gases gushes out from end spiral shell spray orifice, reduce the bullet low-pressure area pressure that the bullet bottom produces when flight, and the flight resistance of bullet reduces, thereby bullet obtains increasing journey.Increasing the journey rate reaches about 30%.When projectile flight when the 7000m left and right sides, the arming delay device of the fuse bullet that detonates.Silver iodide in the bullet are sowed in the clouds by detonation wave.In when emission, after lighting charge column was not only lighted and increased Cheng Fuhe powder column but also bullet and go out big gun, the flame that is produced by its was with the powder gases tracer together that increases Cheng Fuhe powder column burning ejection, indication trajectory.Therefore extremely convenient in night firing.
Claims (4)
1, a kind of end exhaust increases journey artificial rainfall rail-proof bomb, form by body, explosive column, silver iodide, fuse etc., it is characterized in that: end exhaust extended-range device is equipped with in the bullet bottom, it has the compound powder column of a tubular, above the compound powder column lighting charge column, spiral shell at the bottom of one of the bottom suit of compound powder column.
2, artificial rainfall rail-proof bomb according to claim 1 is characterized in that: the end spiral shell in the end exhaust extended-range device is connected with screw thread at the bottom of the bullet, and spiral shell bottom in the end is provided with spray orifice.
3, artificial rainfall rail-proof bomb according to claim 2 is characterized in that: increase the Cheng Fuhe powder column, bore area scribbles efficient ignition powder.
4, artificial rainfall rail-proof bomb according to claim 1 is characterized in that: the lighting charge column diameter is greater than increasing Cheng Fuhe powder column internal orifice dimension, and the tracer powder column of lighting a fire is placed in and increases center, Cheng Fuhe powder column top.
