Study On Disturbance Effects On Dispersion Of A Shoulder-launched Rocket Projectile

The guidance technology of conventional rocket has become an importantdevelopment direction. But as a result of a shoulder-launched rocket weapons of lightweight, good flexibility, particularly, in short distance it’s suitable to damage enemytanks, armored vehicles, field fortifications, and killed effectives etc. So it is thebackbone of weapons which attack soft and hard target. This paper refers to thedevelopment of a shoulder-launched rocket weapons and do some research work formrocket’s dispersion.Firstly, the paper describes the scattering theory of rocket, and discusses, analysesvarious disturbance effects with arising from the rocket’s dispersion. Mainly discussesthe influence of main disturbance effects (initial disturbance, thrust eccentricity,wind).This part of the work for the chapters that follow research provides a basis.Secondly, according to the law of motion, establishes mathematical model. Andcalculates the exterior ballistics, compares with the ideal trajectory, and analysesvarious disturbance effects on rocket’s dispersion and comparates with the measureddata; The theoretical analysis are proved.Finally, according to the calculation, the results of analyse and points out technicalmeasures to improve the accuracy of rocket.The work of this paper for big thrust and high velocity of a shoulder-launchedrocket weapons’ designing ang further studying has provided some design foundationand theoretical basis, and future research to provide aome new ideas and methods.
