The invention discloses a method for determining the aircraft scale proportion of an aircraft lightning partition test, which comprises the following steps of: processing simplified aircraft scale models with different proportions by simplifying an aircraft model, and carrying out a simplified lightning attachment test on the simplified aircraft scale models to determine the aircraft scale proportion of the aircraft lightning partition test. Calculating the attachment probability from the lightning attachment point to the vertical fin and the aircraft back of the simplified aircraft scaling model in the horizontal flight attitude positive polarity discharge state, and judging the conformity between the lightning partition test result obtained in the specific scaling test and the result of the real aircraft lightning initial attachment point; therefore, the optimal scaling ratio of the scaling model used in the thunder and lightning partition test is determined. According to the method, the appropriate scaling ratio can be accurately determined, and favorable support is provided for rapidly judging the conformity of a lightning partition test result obtained in a specific scaling test and a result of a real aircraft lightning initial attachment point.

    本发明公开了一种飞机雷电分区试验飞机缩比比例的确定方法,是通过简化飞机模型,加工出不同比例的简化飞机缩比模型,并针对简化飞机缩比模型进行简化的雷电附着试验,计算简化飞机缩比模型在平飞姿态正极性放电状态下雷电附着点到垂尾和机背的附着概率,并判断在特定缩比试验中所获得的雷电分区试验结果与真实飞机雷电初始附着点的结果的符合性,从而确定雷电分区试验中使用的缩比模型的最佳缩比比例。本发明能准确确定合适的缩比比例,为快速判断在特定缩比试验中所获得的雷电分区试验结果与真实飞机雷电初始附着点的结果的符合性提供有利支持。
