摘要:

对末敏弹这一全新反坦克武器在减速运动和稳态扫描段的运动特性进行了仔细的研究。恰当地引入了降落伞的附加质量和附加惯性矩,完整地分析了伞体和弹体所受的外力和外力矩,建立了由伞体和弹体组成的末敏弹系统二体运动模型。编制了完整的计算程序。给出了末敏弹扫描角速度、扫描角和扫描曲线随时间的变化,以及扫描覆盖区随高度的变化。计算结果与试验结果有很好的一致性。该模型可进一步用于末敏弹系统的弹道修正、参数优化和弹道模拟。

Abstract:

The motion characteristics of the Target Sensitivity Projectile(TSP),which is a newborn anti tank weapon, are studied in detail. The added fluid mass and inertia moment of the parachute are drawn into properly. The external forces and moments of the parachute and projectile are analyzed completely. A two body motion model of the TSP system, which is composed of the parachute and projectile, is established. A program chart of the whole TSP system is presented. The variations of scanning angular velocity, scanning angle, scanning locus and scanning cover field are shown. The computer results show a good agreement with the test results. The model can be applied further to ballistic correction, parameter optimization and ballistic simulation of TSP systems.

Key words: flight mechanics, exterior ballistics, target sensitivity projectile
