Research on Ballistic Numerical Integration Method Based on Series Method for Iterative Firing Angle
When using the integration method based on trajectory calculation model to solve firing data,it is necessary to derive a large number of models and parameters based on the firing table,and calcu-late the initial firing angle on the actual firing conditions,which brings large amount of calculation and complicated steps.The series method can continuously iterate on any initial firing angle,so that the in-tegrated trajectory can quickly meet the convergence conditions and the firing data that meet the accu-racy requirements can be calculated.This method is based on the Taylor formula to derive the calcula-tion formula for the distance change when the firing angle and the elevation angle change by 1 mrad,and the firing angle is revised during the trajectory integration process to make the range error meet the accuracy requirements.Through statistical analysis of the trajectory and accuracy corresponding to dif-ferent initial firing angles,as well as comparison with commonly used methods for calculating firing data,it is concluded that this method can not only omit the derivation and calculation of accurate initial firing angle,but also improve the program size,calculation speed and accuracy.It has strong practical significance and engineering promotion value.
