某底排火箭复合增程弹解体弹丸飞行阻力特性分析

Analysis of a Bottom Exhaust and Rockets of Compound Extended Range Projectile Disintegrated the Projectile Flying Resistance Characteristic

某底排火箭复合增程弹为分体式结构,战斗部与发动机壳体通过螺纹联接,一次试验中弹丸在火炮约束期和半约束期内发生解体现象,弹体在与发动机壳体螺纹连接的根部发生断裂,通过对参试弹丸的相关参数和弹道跟踪雷达测得速度-时间曲线研究,以1943年空气阻力定律和炮兵用标准气象条件为研究方法,对解体前、后级弹丸的弹道参数和飞行阻力特性进行分析计算,还原了解体弹丸的实际弹道参数和飞行阻力特性,通过对分析结果与试验结果进行对比,分析结果与试验测得结果吻合较好,文中提到的研究方法可为弹丸弹道解体或零部件脱落的故障归零提供理论依据,在工程实际应用中有一定的参考价值。

A bottom exhaust and rockets of Compound extended range projectile for fission type structure,the warheads and motor shell through the threaded connection,a test of the projectile with a constraint artillery constraint and disintegration phenomenon occurs,the projectile with the engine casing thread connection of root fracture,through to the volunteers of the projectile related parameters and trajectory tracking radar measured speed-time curve research,in 1943,law of air resistance and artillery with standard meteorological condition as the research method,to the level before and after the disintegration of ballistic parameters of the projectile and the flight resistance characteristic of analysis and calculation,the disintegration of the projectile were actual ballistic parameters and the flight resistance characteristic,through the analysis and calculation results compared with the test results,analysis and calculation results measured results are in good agreement with the experiment,and the research method mentioned in the article can be disintegrated or components for the projectile trajectory provides the theory basis for failure to zero,has certain reference value in engineering application.
