摘要
本文分析了直升机发射火箭精度低的主要原因在于火箭本身随机缺陷(推力偏心等)和火箭/发射器系统随机扰动引起弹道散布大。提高精度措施有:1.增大火箭初速;2.增加出口转速;3.采用被动控制装置。
This paper analysed the causes of inaccuracy fire rockets from helicopter.The principal causes are the random imperfections of rockets (thrust misalignment…)and the random vibration of the launcher/rockets sysrem.The dispersion of rockets trajectories caused by them.The methods of improvement;1.Enlarge the muzzle Velocity;2.Increse the muzzle rotational speed;3.Use rocket launcher as passive controllers.
