二维翼型的气动、隐身综合优化

erodynamic and stealth integrated optimization for 2D airfoils

中文摘要英文摘要

在飞机总体设计中,翼型对于飞机的气动和隐身特性都有着非常重要的影响。本文基于多学科优化综合设计平台isight,以目标的升阻比特性和RCS(雷达散射截面)特性作为优化目标,分别对翼型NACA0012进行了单目标和多目标的算例分析。结果表明气动、隐身单目标优化对翼型变化方向的要求相反,因而进行综合优化是必要的,实施综合优化可以同时改善翼型的气动、隐身性能。

In the synthesis design of aircraft, the airfoil plays an import role in both aerodynamic and stealth features. We analyse both single-objective and multi-objective optimization for NACA0012, using isight as an integrated tool for the multidisciplinary optimization, taking the lift/drag ratio and RCS(Radar Cross-Section) characteristics as optimization targets. We found that the trends of shape change are conflictive for the respective aerodynamic and stealth optimization. Thus the integrated optimization is necessary, and can be used to improve both aerodynamic and stealth features.
