为研究侵彻子弹对机场跑道的毁伤效果,进行了侵彻子弹在各级机场跑道中的爆炸实验。实验结果表明,侵彻子弹在各级实验靶中最佳炸深时的破坏效果由大到小依次为沥青靶、二级靶、一级靶、特级靶;根据实验结果拟合得到炸深与爆坑半径的关系曲线,拟合曲线呈抛物线状,并得到可用于工程计算的公式;此外,拟合出单位炸深时爆坑半径与装药量的关系曲线。研究结果为侵彻子弹的引信设计提供了依据。
In order to study the damage effect of the penetrating bullets on the airport runway, an explosion experiment of penetrating bullets on runways at all levels was conducted. The experimental results show that the destructive effect of the penetration projectile on the best depth of the experimental targets at all levels is descending order of asphalt target, secondary target, primary target and super target. According to the experimental results, The curve of the radius of the blasting pit is parabolic, and the formula which can be used in the engineering calculation is obtained. In addition, the curve of the blasting pit radius and charging quantity when the unit is deep-fried is fitted. The results provide the basis for the design of fuze for penetration of bullets.
