本文利用矩量法(Mo M)计算垂尾模型雷达散射截面(RCS),分析了垂尾前缘后掠角、展长和倾角对垂尾RCS值的影响。并根据计算结果拟合了相应的RCS曲线及函数表达式。计算结果表明,通过优化垂尾前缘后掠角、展长、倾角等几何参数,可提高垂尾的隐身性能。为垂尾的隐身优化设计提供了技术基础。
In this paper, the Moment Scatter (MoS) is used to calculate the RCS of the vertical tail model, and the influence of the sweep angle, length and inclination of the vertical tail on the vertical tail RCS value is analyzed. The corresponding RCS curves and function expressions are fitted according to the calculated results. The calculation results show that the stellar tail stealth performance can be improved by optimizing the geometric parameters such as sweep angle, roll length and dip angle. It provides the technical basis for the stealth optimization design of vertical tail.
