摘要

本文提出了一种具有新型装药结构的发射系统，以改善内部弹道性能。根据新型发射系统的工作特性，建立了一个块参数模型。通过实验获得了推进剂参数和发射系统的内部弹道特性。根据实验结果，通过代码验证了块参数模型的准确性。模拟结果与实验结果十分吻合。在块参数模型的基础上，研究了推进剂参数，如推动力、燃烧速率、腹板厚度和装药质量，以了解发射系统的内部弹道性能。提出了一种优化方法来设计发射系统的推进剂参数。结果表明，优化方案可使弹丸速度提高 9.54%。与传统发射方法相比，弹丸速度提高了 37.09%，而筒内峰值压力没有变化。

Numerical simulation and optimized design of a launching system with a novel charge structure

In this paper, a launching system with a novel charge structure was proposed to improve the interior ballistic performance. According to the working characteristics of the novel launching system, a lumped‐parameter model was established. The parameters of the propellant and the interior ballistic characteristics of the launching system were obtained by experiments. According to the experimental results, the accuracy of the lumped‐parameter model was verified by code. The simulated results were in good agreement with the experimental results. Based on the lumped‐parameter model, the propellant parameters, such as the impetus, the burning rate, the web thickness, and the charge mass, were investigated to understand the interior ballistic performances of the launching system. An optimization method was proposed to design the propellant parameters of the launching system. The results show that the optimal scheme can increase the velocity of the projectile by 9.54 %. Compared with the traditional launching method, the velocity of the projectile is increased by 37.09 % while the peak pressure in the barrel has no change.

期刊介绍： Propellants, Explosives, Pyrotechnics (PEP) is an international, peer-reviewed journal containing Full Papers, Short Communications, critical Reviews, as well as details of forthcoming meetings and book reviews concerned with the research, development and production in relation to propellants, explosives, and pyrotechnics for all applications. Being the official journal of the International Pyrotechnics Society, PEP is a vital medium and the state-of-the-art forum for the exchange of science and technology in energetic materials. PEP is published 12 times a year. PEP is devoted to advancing the science, technology and engineering elements in the storage and manipulation of chemical energy, specifically in propellants, explosives and pyrotechnics. Articles should provide scientific context, articulate impact, and be generally applicable to the energetic materials and wider scientific community. PEP is not a defense journal and does not feature the weaponization of materials and related systems or include information that would aid in the development or utilization of improvised explosive systems, e.g., synthesis routes to terrorist explosives.
