标题： High-speed measurement of rifle primer blast waves

摘要： 本文描述了一种方法和结果，用于利用位于枪口处的高速压力传感器直接高速测量步枪底火爆炸波，以记录底火点火产生的爆炸压力波。 我们的主要发现是：1）大多数测试的底火型号在峰值压力大小上的标准偏差为5-12%。 2）对于大多数测试的底火类型，峰值压力大小与测得的底火质量有良好的相关性，因此通过按质量分类底火可以显著降低标准偏差。 3）不同类型的底火具有从低于200 psi到高于500 psi的峰值压力范围。 显示英文摘要

摘要： This article describes a method and results for direct high-speed measurements of rifle primer blast waves employing a high-speed pressure transducer located at the muzzle to record the blast pressure wave produced by primer ignition. Our key findings are: 1) Most of the primer models tested show 5-12% standard deviation in the magnitudes of their peak pressure. 2) For most primer types tested, peak pressure magnitudes are well correlated with measured primer masses so that significant reductions in standard deviation are expected to result from sorting primers by mass. 3) A range of peak pressures from below 200 psi to above 500 psi is available in different primer types.
