对发射装药引起膛炸机理的讨论

从发射药床破碎导致发射安全性问题的角度出发，指出用基于起始负压差和敏感度试验的压力波安全性标准评定发射装药发射安全性的依据不充分，而且可操作性差。一般情况下，压力波强度与最大膛压之间不存在对应关系。压力波大小既不能表征膛内发射药的破碎程度，也不能准确完全地反映发射药破碎所处力学环境。评定发射装药发射安全性的判别准则应当建立在刻画发射药床破碎程度的基础上。

Discussion About Mechanism of Breech-Blow Caused by Gun Propellant Charge

From the view point of the fracture of propellant charge causing problems of launch safety, it is pointed out that the safety procedure of pressure wave is inadequate to assess the launch safety of gun propellant charge, which is based on the initial negative differential pressure and sensitivity tests, and the operation of the procedure is inconvenient. Generally, there does not exist a correspondence relationship between the degree of pressure wave and maximum chamber pressure. The degree of pressure wave cannot describe the degree of fracture of propellant charge in the chamber, and Cannot depict the environment of the fracturing propellant charge exactly and wholly. The criteria of identification for launch safety of gun propellant charge should be built up on the basis of depicting the degree of propellant fracture.
