摘要: 针对37 mm人工影响天气作业高炮推导非标准气象条件下质点外弹道的计算方法,分析弹丸分别受横风和纵风影响时的弹道侧偏及射程修正。结果表明:风对高炮弹丸的运动轨迹影响较为剧烈。纵风通过影响空气阻力的大小和方向,改变弹道射程;横风影响空气阻力的方向,从而使弹道轨迹产生顺风向侧偏。在同一发射仰角下,随着风速的变化,横风引起的弹道偏程修正量和纵风引起的射程修正量呈现出近似等差数列的变化规律。通过拟合分析,得到风速、发射仰角与弹道修正量之间的关系表达式,在实际作业时,可粗略地利用该数学表达式快速估算任意风速下的弹道修正量。

Abstract: After deducing external trajectory calculation method under non-standard atmospheric conditions for 37 mm anti-aircraft gun, which was widely used in the field of weather modification, the ballistic data in uniform cross wind and range wind field were simulated. The results show that the wind made a great influence on the flight path of projectile. The range wind can change the ballistic range by affecting the size and direction of air resistance. The cross wind can generate a lateral deviation of the trajectory along the wind by affecting the direction of the air resistance. On the same launch elevation angle, with the change of wind speed, the trajectory deviation correction caused by cross wind and the range correction caused by range wind showed a variation law that was similar to arithmetic progression. Through fitting analysis, the relationship among wind speed, elevation and trajectory correction was obtained,which can be used to estimate trajectory correction under arbitrary wind speed in actual operation.

Key words: weather modification operation, safe firing area, uniform wind field
