【摘要】 安装激光定距引信的伞降空炸子母弹,降落时受气流影响呈倾斜降落姿态,引起激光引信在同等高度上的光程变长,导致实际空炸高度低于所装定的最佳高度。为修正因弹体倾斜而出现的定高误差,提出一种通过测弹轴倾角来修正子母弹定高高度的方法,文中分析了单、双轴两种定高修正模式。实验结果表明,当弹轴倾角低于50°时,修正值误差不超过8.1%。此方法在修正子母弹空炸高度研究领域中具有一定的可行性。更多还原

【Abstract】 Aerial parachute shrapnel with laser range-finding fuze is in heeling condition in the air generally,it results in the laser furze’s optical path and distance measurement increase.Eventually,this would lead to the actual bombing height range below the set height range of the best aerial bombardment.To correct the high-altitude error because of the elastic axis is in heeling condition,a method based on gravity was put forward.The experiment result shows that the correction error does not exceed 8.1% when elastic axis angle is less than 50°and the method has reference value in height correction of the aerial parachute shrapnel to some extent.更多还原
