This paper presents four arrangement methods of multiple tube grain in the combustion chamber and the theoretic calculating formulae for the grain number n and relative exterior diameter (?). Several formulae for computing grain number n in the"hexagonal crowded arrangement"have been corrected. Results of the computer calculations have been optimized. Finally, a group of grain design curves have been given to meet the requirements of various web coefficient (?). These curves have practical significance to the...

This paper presents four arrangement methods of multiple tube grain in the combustion chamber and the theoretic calculating formulae for the grain number n and relative exterior diameter (?). Several formulae for computing grain number n in the"hexagonal crowded arrangement"have been corrected. Results of the computer calculations have been optimized. Finally, a group of grain design curves have been given to meet the requirements of various web coefficient (?). These curves have practical significance to the grain design of some missiles, rocket launchers and rocket boosters.

本文提出了多根管状药在燃烧室中的四种排列方式及其装药根数n和装药相对外径(?)的理论计算公式;纠正了六方密实排列n值计算的几个公式。通过对电子计算机计算结果的优选,最后给出一组满足不同肉厚系数ē_1要求的设计曲线,对某些导弹、火箭发射器及助推器的装药设计有实用价值。

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.
