摘 要:为同时获得良好的气动和隐身性能,基于外形隐身技术与材料隐身技术相结合的原理,提出了一种以透波为主的机翼蒙皮设计方案;为平衡透波机翼升力与机翼电磁隐身性能之间的关系,采用一种基于代理模型的策略,对透波机翼外形几何特征参数进行了优化设计。研究结果表明,经过优化后,透波机翼在频域、空域范围内保持良好的雷达散射截面(RCS)减缩特性的同时可具备足够的升力条件。所提出的代理模型精准度高,在工程上平衡跨学科领域问题时,可作为一种有效手段。In order to obtain good aerodynamic and stealth performance at the same time,based on the principle of combining shape stealth technology with material stealth technology,a design scheme of wing skin based on wave transmission is proposed.In order to balance the relationship between the lift force and the electromagnetic stealth performance of the wave transmitting wing,a surrogate model based strategy is adopted to optimize the geometric parameters of the wave transmitting wing.The results show that after optimization,the transonic wing can maintain good RCS(radar cross section)reduction characteristics in frequency domain and spatial domain and have enough lift conditions.The proposed proxy model has high accuracy,and can be used as an effective means to balance interdisciplinary problems in engineering.
