Title multi-station high-altitude meteorological data to large-caliber long-range artillery ballistic characteristics analysis
Abstract
Before the 1960s, mostly due to the artillery range 15 ~ 25km, artillery positioning and other technical standards are not high, the proportion of meteorological factors accounted acceptable. However, with the development and use of weapons and basic theory, weapons and equipment, weapons development and performance of various test equipment, artillery range greatly improved, reducing the proportion accounted for other factors, so that the proportion of meteorological factors accounted for the increase, already It can not be ignored. The issue with a large-caliber long-range artillery for the research object, flight dynamics model of six degrees of freedom by establishing a projectile trajectory equation, using a single-step Runge-Kutta method, the calculated impact point in the solution, on the basis of speed, through research the numerical analysis of single and multi-station weather station data to multiple weather stations layout program, the use of meteorological data and other multi-station their ballistic characteristics (range, cornering, flight stability, etc.), and for large diameter remote Development shells provide a reference.

1.1 课题研究背景
对于大口径远程火炮，其弹道范围都是在大气层中的。然而，大气的实际状态会严重的影响到大口径远程炮弹的弹道性能。由于科学技术水平与气象诸元测试方法的限制，目前大口径远程火炮射击气象保障精度还是比较低的。气象保障精度占总射击精度的比例比较大。以155远程火炮为例，气象诸元误差占总射击精度的比例为65%~70%，而对于火箭炮的射击精度，气象诸元误差占总误差的比例为90%左右。
