摘　　要：由于旋转稳定弹丸飞行稳定性随阵地高程变化的特性缺乏系统研究,以某155 mm榴弹为例,探究了旋转稳定弹丸的飞行稳定性条件,仿真分析其陀螺稳定性、动态稳定性、追随稳定性随阵地高程的变化特性。结果表明,某一高程的全弹道上,若在炮口处弹丸的陀螺稳定性得到满足,在全弹道上必然满足陀螺稳定性,随着高程的增加,陀螺稳定因子增大,陀螺稳定性增强;高海拔条件下空气密度减小有利于旋转弹丸保持动态稳定性,随着高程的增加,动态稳定性显著增强;动力平衡角随阵地高程的增加而增大,弹丸的追随稳定性变差,但若弹道上满足追随稳定性条件,高海拔弹道的整体稳定性强于低海拔。在高海拔条件下,应当避免用高射界射角射击,防止动力平衡角过大导致飞行失稳。In response to the lack of systematic research on the characteristic of flight stability of rotating stable projectiles with variation of position elevations,with the 155 mm howitzer as an example,the flight stability conditions of rotating stable projectiles were analyzed,and the characteristics of the gyroscopic stability,dynamic stability,and tracking stability with variation of position elevations were simulated and analyzed.The results show that on a certain elevation of the full trajectory,as long as the gyroscope stability of the projectile at the muzzle is met,it will inevitably meet the gyroscope stability on the full trajectory;as the elevation increases,the gyroscope stability factor increases,and thus the gyroscope stability enhances;under high altitude conditions,a decrease in air density is beneficial to maintaining dynamic stability,and with the increase of elevation,dynamic stability is significantly enhanced;the dynamic balance angle increases with the elevation of the position,and the tracking stability deteriorates.However,as long as the tracking stability conditions are met,the overall stability of high-altitude trajectory is stronger than that of low altitude;under high altitude conditions,it is necessary to avoid shooting at high firing angles to prevent the occurrence of excessive power balance angles that may cause fight instability.
