摘要单兵制导火箭弹作为一种低成本制导弹药,目前已成为常规武器发展方向,其射击精度是武器系统的一项重要的战术技术指标,但如何对制导火箭弹的设计精度进行评估,目前并没有规定。本文首先建立了单兵制导火箭弹的优尔自由度模型,并求解出了单兵制导火箭弹在无误差干扰下的运动参数;然后运用 Monte-Carlo 法进行弹道仿真,得到了关于单兵制导火箭弹的圆概率误差,并绘制了模拟仿真的打靶图,在此基础上分析了包括惯导误差、气动误差、发动机推力偏心以及风对单兵制导火箭弹精度的影响。31119 毕业论文关键词 单兵制导火箭弹 制导精度 Monte-Carlo 法 CEP
Title Analysis of inpidual guided rocket guidance accuracy
Abstract Inpidual guided rocket as a low cost guided munitions. At present, it has become conventional weapons development direction, the firing accuracy is weapon system an important tactical and technical index, but how to design precision of rocket projectile evaluated. At present, there is not a requirement. In this paper, we first establish the six degree of freedom model of inpidual guided rockets, and solve the inpidual guided rocket in the absence of interference error motion parameters. Then the paper Monte Carlo method trajectory simulation, on inpidual guided rockets circular error probability is obtained, and draw the simulation shooting chart, based on analyzed including the influence of inertial navigation error, pneumatic error, engine thrust eccentricity and wind on the accuracy of inpidual guided rocket.
