火箭被动控制技术

本文讨论了火箭被动控制发射的力学模型,给出了某火箭武器的被动控制发射动力学仿真计算结果,分析了支承位置、出管转角、缺陷方位、推力偏心、动不平衡等因素对被动控制性能的影响,并就被动控制技术的实用性做了初步分析.计算结果表明,如果被动控制器结构参数合理,被动控制技术可使火箭缺陷引起的弹道偏差减小80%以上.

ROCKET/LAUNCHER PASSIVE CONTROL TECHNOLOGY

This report has given a physical model of rocket/launcher pas- sive controller and some results of passive control dynamics with computer simulation.The effect of the bearing position,the rocket rotation angles at end-of-guidance,the orientation of the imperfec- tion,thrust misalignment,dynamic imbalance,etc.on the perfor- mance of passive controller are analysed.At the end of the paper, the feasibility of passive control technology has been discussed.The calculated results show that if the rational parameters were selected, ballistic deviation due to rocket imperfections could be reduced to one-fifth or less.
