Modeling of Two-rigid-body System for Traj ectory Correction Proj ectile With Fixed-canard
摘要
Abstract
The correction components of 2D trajectory correction projectile(TCP)with fixed-canard have different roll-angular velocities relative to the body,and 6D trajectory model can’t effectively describe the motion characteristics of the proj ectile.To solve this problem,the proj ectile was treated as two rigid bodies.Under the assumption that the front component and the aft component have no pneumatic coupling,new coordinate frames were built,and mathematical rela-tionship between the force of the fixed component and airflow by redefining attacking angle and side slip angle was described.The relations of the movement of proj ectile,the correction component and the body component were studied.The interactive force between two rigid bodies during flight was analyzed.The 7D ballistic model was built through integrating kinematic equations and dynamic equations.Aiming at one fin-stability shell,the simulation model was built,and the simulation was carried out.The results show that this model can describe the motion state in the flight and reflect the traj ectory characteristics.This model can be used for ballistic solution,and it provides reference for studying the proj ectile.关键词
