摘要
为了为某无柄手榴弹总体及其引信设计和运用提供参考,以仿真得到的空气动力特性参数为基础,通过数值求解该无柄手榴弹外弹道质心运动方程,得其外弹道特性。手榴弹在空中飞行时会翻滚,其外形应尽可能设计成球形,质心应位于或靠近阻力中心。最大投掷距离对应的出手角度为42°~45°。手榴弹外弹道与真空弹道差异较大。高原最大投掷距离明显增大,但全飞行时间增长较小。
Based on aerodynamic characteristic parameters from simulation,the exterior ballistic characteristics were obtained by solving exterior ballistic mass center motion of no-stick hand grenade in order to provide reference for design and application of no-stick hand grenade and its fuze. The no-stick hand grenade will tumble when flying in the air,therefore its shape should be designed as spherical as far as possible and the mass center should be located at the center of air resistance or near it. The throw angle corresponding to the maximum thrown distance is from 42 degrees to 45 degrees,but it has a little effect on the maximum thrown range when the throw angle is between 40 degrees and 50 degrees. The difference between the no-stick hand grenade＇s exterior ballistic and vacuum ballistic is large. The maximum thrown distance increases significantly in plateau environment but the full flight time increases little.
