垂直转弯 meaning in Chinese

vertical turn

In the end of this thesis , on the basis of the mathematical model , three segments of trajectory : the vertical turn , the pn guidance and the direct lateral force control in terminal trajectory are simulated . the results show that with the direct lateral force control reduces in terminal trajectory , the miss - distance is reduced and the precision is improved
4 、论文最后根据前面建立的数学模型，对防空导弹垂直转弯段、比例导引段以及末端直接力控制段进行了仿真计算，结果表明进行末端直接侧向力控制可以有效减小拦截目标时的脱靶量，提高命中精度。
