圆锥形导偏体导偏性能试验研究

EXPERIMENTAL STUDY ON THE GUIDING-DEFLECTION PERFORMANCE OF CONES

导偏技术是对防护工程进行有效防护,使其免受精确制导武器打击的技术途径之一．采用球墨铸铁圆锥导偏体,进行了37mm半穿甲弹模拟打击试验．试验结果表明:导偏结构可使弹体偏转10°以上,弹体导偏后对靶体的侵彻深度减少了2／3以上．在试验的基础上,又对这种导偏体的导偏机理和误差原因进行了分析,并指出导偏结构后部一个阻力尽可能小的空间是弹体形成尽可能大偏转角的必要条件之一．这种导偏结构可以应用于重要的国防和人防工程之中．

Guiding-deflection technique is one of efficient technical ways to protect engineering constructions against precision-guided weapons. In this paper, ductalloy guiding-deflection cones （GDC） are adopted, and simulated impact tests with 37 mm semi-armour piercing projectiles are carried out to test the guiding-deflection performance of the GDC structure. Test results indicate that the structure can make the projectile deflect more than 10 degrees, and the penetration depth into the target is reduced to less than its 1/3. On the basis of test results, the guiding-deflection mechanism of GDC as well as the test errors are analyzed, and a conclusion is reached that a space with as small resistance as possible behind the guiding-deflection structure is one of prerequisites to achieve large deflection angles. The guiding-deflection structure can be applied in some important engineering constructions of national defence and civil-air defence.
