对建立我国炮兵高空标准气象条件的分析和建议

Analysis and Suggestion of Standard Atmospheric Condition at Super-altitude for Chinese Artillery

针对我国炮兵用标准气象条件缺少30 km高度以上气象参数分布的情况,根据超远程、高空飞行弹箭的弹道设计、弹道标准化及射表编制对高空标准气象条件的要求,给出了适合高空远程弹箭飞行的动力学模型.在对高空气象探测火箭实测气象数据分析的基础上,分析了气温、气压、空气密度随高度的变化规律,提出了56 km以下、可初步供国内开展高空飞行弹箭研究使用的高空标准气象条件.以150 km射程远程火箭为例,分析了不同高空气象条件对飞行弹道的影响,为远程高空弹箭研究提供了参考.

Atmospheric parameters above 30 km altitude for Chinese artillery are lacking in standard atmospheric condition. Aiming at this problem, the dynamic model was presented according to the high-altitude atmospheric condition satisfying the ballistic design, ballistic standardization, firing table compilation of super-range high-altitude rocket. Based on analysis of atmospheric data measured by high-altitude rocket, the variation laws of air temperature, air pressure, air density following the height were analyzed. The standard meteorologic condition under 30 km altitude was brought forward which can be used to carry out the study of high-altitude rocket preliminarily. Taking long-range rocket of 150 km range for example, the effects of different high-altitude meteorologic conditions on trajectory were analyzed. It offers reference for the study of long-range rocket with high-altitude.
