摘要:
为了实现全程可控弹道修正弹的修正方案,通过对弹道模型的分析确定了增阻系数是实现这一方案的关键。以质点弹道模型为基础,采用多项式拟合的方法确定射程修正量与阻尼器展开时刻的关系式,利用分段解算弹道的方法确定多项式系数,最后采用二分法完成对阻尼器展开时刻的计算,在MATLAB软件平台下对不同增阻系数下的弹道修正效果进行了仿真分析。仿真结果表明,随着修正量的增加,增阻系数越大,弹道解算时间越长,弹丸的落角逐渐增大、落速迅速减小; 随着增阻系数的增加,弹丸修正能力显著提高,但随着修正量增加,落点精度逐渐降低。其次对最优增阻系数下的修正弹进行了仿真及试验研究,试验结果与仿真结果相互吻合,为全程可控弹道修正弹增阻系数的选择提供了依据。
Abstract:
In order to realize the correction project of a whole-course-controllable(WCC)trajectory correction projectile,through the analysis of a trajectory correction model,this paper presents how to determine the increase-resistance-coefficient(IRC)is the key to realize the correction project.Based on the particle trajectory model,a polynomial fitting method is utilized to determine the equation between correction range and the damper opening time.Polynomial coefficients are determined by the method of piecewise calculating trajectory.A bisection method is used to get the result of the deployment time.On the MATLAB software platform,the trajectory correction effect of different IRC is simulated.The simulation results show that with the increase of the correct distance and the IRC,the ballistic calculation time increases,the falling angle of a projectile progressively increases,and the falling velocity of a projectile decreases rapidly; with the increase of the IRC,correction capability is enhanced significantly.However,with the increase of the correction distance,the landing accuracy decreases gradually.Secondly,the simulation and experimental research are done on the correction projectile based on the optimal IRC.The test and the simulation results agree with each other,which provides the principle to select an IRC for WCC trajectory correction projectile.
