直升机载制导火箭弹命中精度评定研究

针对直升机载制导火箭弹特点,根据命中精度概念,分析出直升机载制导火箭命中精度的合理表示方法;考虑研制成本、试验条件等因素,提出研制阶段基于点估计和区间估计的制导火箭命中精度评定方案,并通过试验数据验证其正确性。鉴于产品批量生产交付阶段抽检质量时实弹难以统计弹着点和用弹数量有限的困难,提出了CEP评定转换为命中率考核,采用截尾序贯法,并进行优化的评定方案。

Research on Assessment of Hit Probability of Guidance Rocket Aboard Helicopter

Aiming at characteristic of guidance rocket aboard helicopter,according to definition of hit probability,proper representation way of hit probability of guidance rocket aboard helicopter is given,taking development cost and experiment condition into account ,point estimation and interval estimation assessment scheme for development stage is proposed,and validity is proved through experiment data,in view of difficulty in counting hit point and limit number of guidance rocket for casual inspection of quality when product is hand over in batch,the scheme that turns CEP into hit rate,uses censored sequential method and optimizes in further way is proposed.
