Research progress on explosives for naval gun shell and its launching safety

Abstract

<p indent="0mm">To investigate the launch safety problems in the application of powerful naval gun ammunition, this paper analyzes and studies the development of domestic and foreign explosives and weaponry for naval gun ammunition, the research equipment for explosive charge launching safety, impact mechanism of explosive charge launching safety, and the design of numerical simulation and equivalent test for explosive charge launching safety. Results show that although the explosive charge of naval gun ammunition varies among countries, the principle of the test device used to study the explosive charge launching safety is basically the same. To verify whether the explosive charge meets the launch safety requirements, the recoil force stress and its response to explosives in the launching process is simulated. Additionally, the relevant test and research results prove that the launching safety performance of explosive charge can be effectively enhanced by improving the charge quality and reducing the charge defects. By exploring the explosive formula design and charging technology, avoiding the hot spot of explosives in a complex stress launching environment, such as adiabatic compression and shear, is a crucial technical measure, as well as improving the launching safety of naval gun shell explosive charge.
