| 摘 要： | 联结翼布局与常规布局相比具有结构重量轻、诱导阻力小、升力系数大、稳定性良好的特点。本文选取5个对联结翼布局影响明显的设计变量,利用数值模拟的方法研究不同设计变量对联结翼气动特性的影响。同时,应用了旨在提高优化计算效率的响应面方法。在优化设计中采用模拟退火算法对目标函数进行优化求解。研究结果表明,在机翼面积不变的情况下,增大前、后翼弦向距离以及两翼间的翼隔,采用V型翼差角布局方式,能有效降低两翼间的相互干扰,增大升阻比。

| Abstract: | The joined-wing,characterized by low structural weight,small induced drag,big lift coefficient and good stability,is different from normal layout.Five design variables which have significant effect on the joined-wing are selected,and influence on the aerodynamic performance of joined-wing is analyzed by numerical simulation in this paper.Moreover,response surface methodology is applied to improve optimization efficiency,and simulated annealing algorithm is used to solve objective functions in optimization d... |
