摘　　要：为了解旋转稳定弹丸高原弹道的变化机理和运动规律,根据刚体弹道理论,建立了旋转稳定弹丸质心和弹丸姿态运动微分方程。在分析高原环境对旋转稳定弹丸弹道特性影响的基础上,通过平原、高原试验测试数据的对比验证,分析了旋转稳定弹丸高原射击密集度、飞行阻力系数的变化及高原环境对弹丸质心运动的影响因素,确定了旋转稳定弹丸高原运动规律及其成因。结果表明:试验结果与理论分析基本一致,旋转稳定弹丸高原质心运动较平原有较大差异,而其高原姿态运动的基本规律与平原相似。研究成果为掌握旋转稳定弹丸高原飞行规律,提高武器装备高原射击精度奠定了重要的理论基础。In order to study the change mechanism and motion law of trajectory of spin-stabilized projectile （SSP） on the plateau, the motion differential-equations of centroid and attitude of the SSP were established. The test data on the plain and plateau were compared. The variations of firing density and flight drag coefficient of SSP on the plateau were analyzed, as well as the effects of plateau environment on the motion of projectile centroid. The rules and reasons of motion of SSP on the plateau were determined. The results show that the experimental results are in agreement with the theoretical analysis. The centroid motion of SSP on the plateau is significantly different from that on the plain, but the basic rules of attitude motion on the plateau are similar to that on the plain. The research results offer theoretical foundation for mastering the rule of motion of SSP and improving the firing accuracy of weapons and equipment.
