Based On The Two-dimensional Trajectory Correction Technology Of The Effect Of Drift

This article mainly aims at the realization of the precise attack weapons ammunition, increase hit probability this goal, research ballistic simple control technology, mainly on the two-dimensional trajectory aerodynamic analysis to complete the research content.Firstly, the two-dimensional trajectory correction correction model was established, according to the technical scheme of two dimensional correction projectiles, in conventional artillery six freedom degrees ballistic model foundation, increase the longitudinal damping loop correction force, moment and transverse adjustment of roll rate damping mechanism damping force and torque, the establishment based on the drift effect the two-dimensional trajectory correction projectile correction model.Secondly, the two-dimensional trajectory correction mechanism pneumatic design analysis, development uses two times of shock expansion theory to calculate the two dimensional correction projectile aerodynamic characteristic study of software module, two-dimensional trajectory correction to body size, shape on the aerodynamic characteristics of projectile impact, design reasonable structure and size of the two-dimensional trajectory correction mechanism.Finally, the two-dimensional trajectory correction trajectory characteristic analysis, through the establishment of the two-dimensional trajectory correction trajectory model and obtain the damping mechanism of aerodynamic characteristics, analysis of various types of correction of exterior trajectory correction effect, flight stability characteristic, exterior ballistic characteristics, and the theory of external trajectory design method, flight stability conditions of.
