Based On The Two-dimensional Trajectory Correction Of Thrust Vector Actuators

In the modern battlefield, to increase the accuracy by improving conventional ammunition is playing a very important role, and the trajectory correction projectile is a very significant part of them. Since21st century, the trajectory correction projectile is being valued all over the world, the trajectory correction projectile can reduce the deviation of trajectory caused by random factor and attack mobile target efficiently. So it can improve the accuracy of firing, and decreases the cost of the projectiles.After studying several common ways of the2-Dimension trajectory correction projectiles,2-Dimension trajectory correction with Impulse for projectiles is presented. The structure and basic working process are described. As the background of some grenade, Firstly, the3D-solid model of the structural is completed by using PROE software. Secondly, the analysis of launching strength is conducted with ANSYS software, and corresponding optimization is made. Thirdly, flow field of the trajectory correction projectile was simulated with FLUENT software, and the drag the coefficients and coefficient of form are obtained. At the last, the external ballistic of the trajectory correction projectile is emulated with Matlab software, and the influences, that some factors have, on trajectory correction are analyzed. This paper provides references for the design of2-Dimension trajectory correction projectiles...
