中大口径舰炮射程性能提升研究现状与发展趋势综述OA

In the complex maritime combat environment,medium and large-caliber naval guns have advantages such as high efficiency and adaptability,but their disadvantage in range limits their combat performance.Therefore,improving the range performance of medium and large-caliber naval gun weapons is of great significance.Based on the current research status of naval guns in key fields such as chamber pressure optimization,new barrel technologies,new firing methods,and lightweight and reduced recoil,this paper systematically reviews the development and application of related technologies at home and abroad.Focusing on the chamber pressure optimization technology,the research progress in high-energy propellant formulations,chamber design,and loading methods is summarized;in the new barrel technology section,the positive effect of barrel length on range and the constraints mechanism due to structural dynamics and thermal accumulation effects are analyzed;for new firing methods such as electromagnetic firing,electro-chemical firing,and hydrogen-oxygen light gas firing,the development bottlenecks and application potential of each technology are analyzed;in addition,the key supporting roles of lightweight materials,structural optimization,and advanced recoil reduction technologies in ensuring system suitability and shooting accuracy are expounded.Finally,the development of improving the range performance of medium and large-caliber naval guns is summarized and prospected.
