指向精度是衡量导弹发射筒发射精度的一项重要指标，为导弹提供了初始的出筒角度，是导弹是否能够准确命中目标的关键因素之一。本文通过剖析某舰载倾斜固定式导弹发射筒的总体结构，确定了影响导弹发射筒指向精度的因素，运用基于均方根值和最大值相结合的误差分析理论对导弹发射筒的指向精度进行统计计算，结合数据对比分析，提出1套可靠且系统的研究方法。该研究方法在一定程度上解决了影响导弹发射筒指向精度各个因素之间的相位角问题，较为客观地反映了指向精度的真实情况，对导弹发射筒总体设计具有一定的指导意义和应用价值。
Pointing accuracy is an important index to the precision of missile launch canister. Providing the initial angle when a missile is launched, pointing accuracy is a vital factor deciding whether a missile will hit its target precisely. This research paper decides the factors that influence the precision of missile launch canister by analysing the overall composition of a ship-based oblique fixed missile launch canister and puts forward a reliable and systematic research method based on the comprehensive analysis of RMS and Maximum's error and the comparison of data. To some degree, this research method decreases the influence of phase angle of various factors that influence the precision of missile launch canister and reflects the pointing accuracy relatively truthfully, offering instructive function and application value to the overall design of missile launch canister.
