初步设计阶段桅杆外形的隐身性评估与改进

Stealth evaluation and improvement of mast configuration in the preliminary design stage

  • 摘要: 桅杆作为重要的雷达波散射源,将直接影响到整个舰船的隐身性。在舰船设计初期,如何评估和改进桅杆的隐身性显得十分重要。以一个典型的封闭式桅杆为研究对象,分析评估参数对隐身性计算结果的影响,得到该桅杆的主要反射机制,识别出桅杆大部分RCS峰值是由单次反射引起,并给出桅杆外形隐身调整建议。结果显示,若发生横摇,附属平台和桅杆主体结构产生的二面角效应会增强,所得结论可为初步设计阶段舰船桅杆的隐身性评估和改进提供参考。

     

    Abstract: The stealth performance of warships is directly affected by its mast;therefore, the analysis and evaluation of the stealth performance of the ship's mast in the preliminary design stage is the main research purpose of this paper.By taking a typical enclosed ship mast as the research model, the influences of several important parameters on the stealth performance are analyzed, with the major scattering characteristic of the mast being investigated.It is seen that most of RCS peak points are caused by the specular reflection, and the optimal adjustment of mast configuration is presented.When the ship is rolling, the dihedral angle effect caused by the affiliated platform and main structure would intensify.This paper provides a reference for the stealth performance evaluation and improvement of mast configuration in the preliminary design stage.
