火炮最大射程地面密集度分析与预测

Analysis and Prediction of Gun Maximum Range Ground Dispersion

火炮最大射程地面密集度是火炮武器系统的重要战术技术性能指标之一,也是射击精度的重要组成部分。以某火炮最大射程地面密集度为研究对象,分析和研究了影响密集度的主要因素及起始扰动对弹道的影响,建立了模拟实际大气阵风风速随机变化的Markov随机风场,采用了符合误差因素特征的随机数,运用弹道方程法建立了密集度预测模型。该模型真实反映了主要因素影响密集度的机理,并考虑了各主要误差因素的交互作用。

Maximum-range ground artillery dispersion is an important tactical and technical performance indicator, and also an important part of fire accuracy. In this thesis, dispersion of some artillery weapon was studied. By analyzing the factor of dispersion, the physical processes of influence done by these factors on dispersion were further understood. The influence mechanism that initial disturbance had on dispersion was established. With a Markov random wind field establishment, this could simulate the atmospheric gust changing randomly in both spatial and time domain. Random numbers with features in accordance with factor were adopted. After synthesizing the major sources of error, dispersion calculation was made with the trajectory equation. The method reflected the mechanism of the main error sources on the dispersion factually and also computed the interaction between the main error sources, which could avoid the error of approximate compute.
