| 摘 要： | 对直升机航炮系统射击误差源进行了分析。根据直升机飞行特点建立直升机航迹简化模型，根据直升机对地攻击特点建立相关数学模型并编制仿真软件。选取典型航迹进行分析，对直升机对地攻击单发弹命中率进行计算。按系统误差和随机误差均方差的指标要求进行计算，得出在火控随机误差均方差基本确定的情况下，系统误差及火力误差均方差的变化对直升机航炮系统单发射击命中率影响的关系图。该方法可为直升机航炮系统设计研究提供参考和理论支持。

| Abstract: | The error source of helicopter gun system was analyzed.The simplified flight path model was built up according to helicopter's flight characteristics.The relative mathematic model was established,and the simulation program was worked out according to firing characteristics of helicopter's attacking to the targets on the ground.Representative flight paths were chosen to calculate the hit probability of single shot.According to the parameter requirements of system error and mean square deviation of random err... |
