基于改进型六幕光幕靶的弹道测量技术研究

Research on Ballistic Measurement Based on Improved Six-Laser-Screen

现有的六幕光幕靶测量系统实现了近距离弹丸速度、姿态以及着靶坐标的测量,而在实际工程应用中需要计算的是弹丸整个飞行过程中的速度、姿态以及远距离的落点坐标。针对现有系统工程部署中的不足,提出了双交叉结构的六幕光幕靶的设计原理。利用双交叉结构的六幕光幕靶的测量结果以及外弹道计算原理,通过四阶龙格-库塔方程建立了弹道测量模型,实现了弹丸飞行全过程的弹道测量和计算。通过使用弹道系数1.0的标准弹丸进行仿真实验和分析,计算出其射程和射高分别可以达到16 269m和3 672m,证明了其与实际的弹丸运动曲线相吻合,能够实际应用于工程部署。

Though the existing six-laser-screen measuring system could measure the close-distance projectile velocity,flight attitude and projectile impact coordinates,the actual engineering applications need calculate the projectile velocity,flight attitude and long-distance projectile impact coordinates of the whole flight process.Aiming at the deficiency of existing system in deployment,the design principle of the six-laser-screen of double-cross structure is put forward.Using the six-laserscreen measurement of double-cross structure and principle of exterior ballistic calculation,with the fourth order Runge-Kutta equation created a model of ballistic measurement,the measurement and calculation of the whole process of the projectile flight are achieved.Through simulation and analysis by using the ballistic coefficient of 1.0standard projectile,the calculation of its range and shoot height can reached 3 672 mand 16 269 mrespectively.The simulation results prove that it coincides with actual projectile motion curves,and can actually be used in engineering applications.
