投弹误差描述方法及其合理性分析

Descriptions for Bomb-dropping Error and Analysis of Their Rationality

目前,投弹误差存在两种描述方法:飞机总体要求的武器火控系统精度和空中靶试要求的弹着点圆概率误差。介绍了这两种描述方法,着重分析了它们之间的关系、矛盾及其存在合理性,提出了由于弹丸散布误差、参数测量误差、投放条件误差等多种误差因素影响,前者是飞机总体现在能达到的指标,而后者是投弹最终目的和奋斗目标的观点。最后,简要提出了解决二者之间所存在矛盾的办法。

Now there are two descriptions for bomb-dropping error. One is the precision of weapon aiming system which is required by the designation of fighter. The other is the bomb error CEP （Circle Error Probability）which is required by air-bombing test. By introducing these two descriptions, their relationships, contradictions and rationality were analyzed in detail. Accordingly, a point of view was advanced： as a result of pill scattering error, parameter measuring error and bombing conditional error, etc, the former description is the degree which the fighter can reach,and the latter is the final purpose of bombing which must be realized. Finally the resolution of their contradictions was put forward briefly.
