根据伞弹系统弹道飞行特征对伞弹弹道模型进行了简化,提出了弹道和落点分析计算模型。根据该模型对影响弹道落点的因素进行了分析,得出了各因素导致的落点散布影响范围和敏感程度。认为载机偏角、载机倾角、机弹侧向分离速度、伞弹自身因素散布和风偏对弹体落点散布的影响较明显,是导致弹体落点散布的敏感因素,并通过计算得到了弹体落点综合散布范围。

Base on the ballistics characteristic the dynamics model of parachute-bomb system is predigested and the ballistic fall point spread model is built up. The influence factor on the ballistic fall point spread of the parachute-bomb is studied and the result is contrasted. And the sensitive factor is pointed out. The conclusion believes that the angle spread of the plane, set machine angle, the spread of the separation velocity, umbrella and the wind spread are the obvious factor on the ballistic fall point spread.
