摘要
随着世界经济贸易的发展,轻中型公务机愈发受到客户的青睐。为了进一步提升高速涡扇公务机的总体气动性能,采用基于全速势方程的流场快速求解方法,集成序列二次规划(SQP)优化算法和类函数/型函数变换(CST)自由变形(FFD)方法,对某轻中型高速涡扇公务机机翼进行多点优化设计研究,并对优化结果进行对比分析。结果表明:优化后公务机全机阻力系数明显减小,阻力发散特性得到了显著改善,优化方法有效引导了机翼气动外形有利变化。
With the development of world economy and trade,the medium business jets are more favored by customers.In order to further improve the general aerodynamic performance of high-speed turbofan business jet,the optimization methods based on the full potential equation,sequential quadratic programming(SQP)and free form deformation(FFD)methods of class function/shape function transformation(CST)are used to carry out the multi-point optimization study for the wing of a medium business jet,and the optimization results are performed with comparison analysis.The results show that the drag coefficient of the optimized wing is reduced obviously,and the drag divergence characteristic is significantly improved.The optimization method can effectively guide the wing aerodynamic shape to change with better aerodynamic performances.
