为解决大口径舰炮发射系统的可靠性问题，进行新技术应用的可靠性影响分析。首先明确全可燃药筒装药技术、激光点火技术和垂直装填技术的应用可行性，表明它们能够简化新型舰炮发射系统的组成结构。然后采用多态模糊故障树理论构建发射系统的故障模型，给出新技术应用的可靠性衡量依据。最后，进行传统与新型舰炮发射系统的可靠性对比评估。获得的结果表明：新技术的应用可以减少发射故障模式，可以使得舰炮发射故障率降低、可靠度提高；相较于改进传统舰炮部件可靠度的方式，新技术的应用具有更好的可实现性，为提高大口径舰炮系统的可靠性提供了有效途径。
To solve the reliability problems of large-caliber naval gun launching system, the influence for its reliability are analyzed when introducing new technique. Firstly, the application feasibility are described for the complete combustible cartridge case, the laser ignition system and the vertical loader technique respectively, of those show the ability to simplify the structural components of novel naval gun launching system. Then, based on the multi-state fault tree method, the fault model is established for launching failure situation, which figures out the reliability analysis bases for the new technique. Finally, the comparative study are carried out for the reliability between the active service and the novel launching system. The obtained results show that the launching failure probability could be decreased and the reliability could be increased when fault modes are reduced by using new techniques. And also, those new techniques are able to realized comparing to improve the components' reliability of the active service gun system, which provides an effective way to ensure the reliability of large-caliber naval gun system.
