Simulation Study of Impact Movement of Rocket Projectile in Direction Pipe

The impact model of rocket projectile's movement in direction pipe was established and bearing load when moving in the pipe of rocket projectile was analyzed.Based on previous work,the simulation model and calculation of impact movement process about rocket projectile in direction pipe were studied,then movement principles were got.Mass eccentricity,thrust eccentricity and windage are main factors affecting impact action and initial disturbance parameter values of rocket projectile in the direction pipe.Thus simulation calculation of impact movement about rocket projectile was done considering above factors,then some useful conclusions were drawn.The simulation study sets base for launching dynamics analysis and better shot accuracy of some rocket launcher,and provides references for optimized structure design and manufacture of rocket projectile and direction pipe.
