Quantitative assessment of the harmful phenomenon of medium and large-caliber muzzle smoke provides crucial support for the development of advanced propellants. Based on the current maximum area method and integration method of transmittance curve of examining muzzle smoke, the Trace Analysis Model of Muzzle Smoke (TAMMS) is proposed. First, based on the characteristics of few mass exchanges and relatively fixed expansion center of muzzle smoke cloud formed by high-pressure release with the slow-release zone, a muzzle smoke characteristic quantity model refers to the area and the concentration corresponding to each other was established. Secondly, a test system was built to experimentally verify the smoke characteristic quantity model, and the test error analysis was carried out. The research results show that the Trace Analysis Model of Muzzle Smoke takes into account the relationship between smoke area and transmittance over time and can more ideally characterize the muzzle smoke volume. The results of parallel testing and analysis of 7 sets of traditional 35 mm guns show good reproducibility, with a measurement uncertainty less than 0.5 dB.

枪口烟雾轨迹分析模型

对中、大口径枪口烟雾有害现象的定量评估，为先进推进剂的研制提供了重要支撑。在现有最大面积法和枪口烟雾透过率曲线积分法的基础上，提出了枪口烟雾轨迹分析模型（TAMMS）。首先，基于高压释放与缓释区形成的枪口烟雾云的质量交换少、扩展中心相对固定的特点，建立了枪口烟雾特征量模型，指的是面积和浓度相互对应为已确立的。其次，搭建了测试系统，对烟雾特征量模型进行了实验验证，并进行了测试误差分析。研究结果表明，枪口烟雾轨迹分析模型考虑了烟雾面积与透过率随时间的关系，能够更理想地表征枪口烟雾量。7套传统35毫米枪的平行测试和分析结果显示出良好的重现性，测量不确定度小于0.5分贝。
