| 摘 要： | 以F-35战斗机为研究目标,对目标体进行三维外形重建,并对重建后的模型进行气动及隐身特性的计算和分析,首先采用了基于飞机三视图进行轮廓线提取来重建F-35全机理论外形的方法,引入了基于草图跟踪的CATIA三视图的标定,大大地提高了模型重建的精度。其次采用非结构网格对F-35的计算区域进行网格划分,采用EULER方程完成了F-35在亚声速、跨声速及超声速等飞行条件下的流场计算,分析了不同状态下的升力、阻力和大迎角气动特性。最后利用曲面像素法对F-35全机高频雷达目标特性进行了计算,提出了一种基于IGS数据转换格式的隐身计算网格生成方法,比较了不同俯仰角及方位角下的RCS特性曲线,分析了对RCS影响比较大的部件。 |
