摘要/Abstract

摘要： 为了综合评价单兵无后坐力炮后喷区域的危险性，通过试验方法对武器系统发射时的冲击波超压、热流强度以及燃气射流喷射时的气流冲量进行了综合测试。对测试数据进行分析，结合概率模型计算得到了人员在不同危险源作用下的创伤概率。结果表明：在半径为5 m、扇形角为120°的后喷危险区域内，冲击波会对人的鼓膜和肺组织造成创伤，且喷管正后方的创伤程度最大，2 m内肺组织创伤概率大于50%；喷火区域直径约为2.18 m，火球中心热流强度最大，人员发生1级烧伤概率达到46.95%，但不足以致命；高速燃气射流产生的气流冲量对人体的创伤具有致命性，特别是当人体头部受到撞击时，致命概率>50%的距离达到3 m.

Abstract: The shock wave overpressure, heat flux intensity and gas jet impulse during the firing of weapon system were tested to evaluate the risk in the back-ejection area of recoilless rifle. Based on the analysis of the test data and the calculation of the probability model, the personnel trauma probability under the action of different dangerous sources was obtained. The results show that shock wave could cause injury to human eardrum and lung tissue in the dangerous area with a radius of 5 m and a fan angle of 120 degrees. The degree of injury is the most serious in the rear of nozzle. The probability of lung tissue injury is more than 50% in 2 m. The diameter of flame zone is about 2.18 m, and the heat flux in the center of fireball is the strongest. The probability of first-degree burn is 46.95%, but it is not lethal enough. The gas impulse produced by the high-speed gas jet is lethal to the human body, especially when the human head is impacted, the distance of fatal probability greater than 50% is 3 m. Key
