一种空气冲击波超压随密度变化的计算模型

高空冲击波超压的计算方法目前尚处于空白阶段,该文基于冲击波相似理论,利用前人对各种不同介质冲击波超压的传播计算方法,计算分析冲击波超压随介质密度改变的变化规律,提出空气冲击波超压随密度变化的计算模型,并对模型进行了运用计算及验证,验证结果理想。

The calculation method of the overpressure of air blast wave in high altitude is still in the blank stage. Based on the similarity theory of blast wave, this paper uses the method of calculating the overpressure of blast wave in different media to calculate and analyze the law of the change of the overpressure of blast wave with the change of the density of medium, and puts forward the calculation model of the change of the overpressure of air blast wave with the change of the density of air. This paper calculates and verifies the model. The results are satisfactory.
