In view of the problem that the turns count technique can not ensure the optimal distance between burst point and high-speed moving target,the adaptive burst point control technique for turns count air burst fuze is presented here. Trie technique can adjust the burst opportunity automatically according to the projectile-target motion,and guarantee the distance between burst point and target is optimal for detonation. Taking the projectile-target encounter process of a head-on attack as an example, the principle and implementation method of the adaptive control technique are discussed. Based on the exterior ballistic model of the small caliber antiaircraft artillery, the error changes of distance between burst point and target are simulated at different target speeds and firing ranges. The simulation results show that,when attacking at high-speed moving target,the adaptive control technique has higher control accuracy than the turns count technique and can improve the lethality of the airburst ammunition.%针对计转数定距技术不能保证炸点与高速运动目标处于最佳距离的问题,提出了计转数空炸引信自适应炸点控制技术.该技术根据弹目相对运动自动调整起爆时机,使炸点位置与目标间的相对距离为最佳起爆距离.以弹目迎面交会过程为例,分析了自适应炸点控制的原理和实现方法,并利用某小口径高炮空炸弹药外弹道模型,仿真计算了炸点-目标距离误差随目标速度和拦截距离的变化情况.结果表明,自适应炸点控制技术在攻击高速运动目标时,具有比计转数定距技术更高的炸点-目标距离控制精度,可以有效地提高弹药对目标的毁伤能力.
