利用弹上器件测风方法

导弹子母弹携带的子弹药战斗部在开舱之后受到风况的影响很大,需要对子弹药的落点进行修正控制以提其的作战效能。针对这一需求,研究了适用于导弹稳定平飞阶段的常值风测量方法。根据导弹弹体姿态＂随风飘＂的特性,提出了一种只利用弹上器件的测风方案,并以水平面内的常值风为例,以概率统计的方法进行了测量误差分析。计算分析结果表明,若在导弹开舱之前稳态平飞阶段内,根据弹上组合导航系统和空速表的多次测量值进行简单的计算处理,测风误差将大大减小。该方案简单可行,易于实现,具有一定的工程应用价值。

Wind measuring method using only missile-borne equipment

The missile cargo warheads are disturbed by the wind after dispensing by the missile, so it is indispensable to correct and control the points of fall for increasing the engagement effectiveness. To meet this requirement, a wind measuring method for the missile stably flying at level track is studied. A wind measuring scheme is presented in which only uses the missile-borne equipment. The measuring errors is analyzed using probability statistics by taking the constant wind in horizontal plane as an example. The calculation results indicate that the wind measuring errors would drastically decrease if dealing with the results measured by the integrated navigation system and pitot. This wind measuring scheme is simple and feasible, and provides a basis for application in engineering.
