简介了末敏弹等弹药发展中降落伞等柔性减速装置的应用情况。主要基于末敏弹降落伞的研制实践和弹药用普通降落伞的设计需求,提出并定义了伞冠和伞冠载荷结构系数等概念,系统性地建立了以伞冠载荷和伞冠承载能力作为主要表征参数的伞冠强度计算及校核的工程计算方法。实践表明,该方法适用于多种伞型的普通降落伞的伞冠结构和强度设计。

Application of flexible reducer such as parachutes in the development of projectile such as terminal sensing ammunition is briefly introduced. It is mainly based on the development practice of the terminal sensing ammunition parachute and the design requirement of the ammunition ordinary parachute, the concepts of parachute crown and structure coefficient of the crown load are proposed and defined, a general engineering calculation method for the strength calculation and checking of the crown was established systematically, in which the crown load and the crown bearing capacity were taken as the main parameters. The engineering practice shows that this method is suitable for the crown structure and strength design of ordinary parachutes with multiple types.
