Electromechanical time fuse of antiaircraft gun hail-mitigating cloud-seeding round

Abstract

The invention discloses an electromechanical time fuse of an antiaircraft gun hail-mitigating cloud-seeding round. The fuse comprises an upper body 1, a wind cap 2, an electromechanical timing ignition mechanism 3, a fuse body 4, a ball rotor safety and arming mechanism 5 and a booster 7, wherein the wind cap 2 covers the front end of the upper body 1, the bottom of the wind cap 2 is closed and fixed in an annular groove in the outer side of the upper body 1, the electromechanical timing ignition mechanism 3 comprises a magnetic recoil power supply and an electronic timing and ignition module,and is positioned inside a cavity of the upper body 1, the rear end of the electromechanical timing ignition mechanism 3 is adjacent to a primary-explosive-free detonator 17, the ball rotor safety and arming mechanism 5 is located inside a cavity of the fuse body 4, the top end of the ball rotor safety and arming mechanism 5 is adjacent to the primary-explosive-free detonator 17, a bulge part ofthe front end of the booster 7 is adjacent to the ball rotor safety and arming mechanism 5, the rear end of the booster 7 serves as a fuse output end, and the the booster 7 is used for initiating projectile charges. According to the electromechanical time fuse of the antiaircraft gun hail-mitigating cloud-seeding round, the timing is accurate, the manufacturability is good, and the reliability ishigh.

Description

technical field [0001] The invention belongs to the technical field of fuzes for anti-hail and rain-increasing bombs, in particular to an electromechanical time fuze for anti-hail and rain-increasing bombs for anti-aircraft guns. Background technique [0002] Small-caliber anti-hail and rain-increasing shells for anti-aircraft guns are generally used in artificial hail-proof and rain-increasing operations. Its mechanism of increasing rainfall and preventing hail is: launch anti-hail rain-increasing bombs 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 small ice particles fall to the cloud layer before they become large hailstones. The purpose of preventing hail on the ground is achieved; the detonation wave spreads the catalyst contained in the projectile in the cumulonimbus cloud layer to generate a large number of crystal nuclei, transforming the "rain cloud" or "hail cloud...
