尾翼稳定弹丸的外弹道相似性分析

ANALYSES OF SIMILARITY FOR FLIGHT TRAJECTORY OF FIN-STABILIZED PROJECTILES

以尾翼稳定弹丸为对象 ,研究了不同口径尾翼弹外弹道相似的可能性 ,得到了两弹在飞行时间、飞行速度、飞行坐标及飞行稳定性规律等方面的相似关系和相似条件 ,讨论了实际应用中可能存在的一些问题 ,这对今后外弹道测试技术中所遇到的一些具体问题 。

The possibility of similarity for flight trajectory of fin-stabilized projectiles has been discussed. The relationship and conditions of similarity between two projectiles in the ballistic parameters of flight time, velocity, coordinates and flight stabilities are obtained. Some problems in practice for similarity are discussed too. All of these will be useful for ballistic measurement in future.
