| 摘 要： | 本文提出了带翼尖帆片的非共面机翼气动力计算以及帆片参数优化计算方法。文中采用涡格法研制了一种有效的非共同气动力计算程序，采用Ｐｏｗｅｌｌ方法进行优化计算，以获得最优的帆片配置方案。设计了某运输机的翼尖帆片，计算了升力和阻力系数，其结果与风洞试验值基本一致。计算和风洞试验结果表明，翼尖帆片对减少机翼的诱导阻力具有明显效果，本文的方法可供翼尖帆片初步设计应用。

| Abstract: | In this paper, we present a computation method for aero-dynamic forces and a parameter optimization method for nonplane wing with wing-tip sails.By using the Vortex Lattice and the Powell methods in the computation and optimization, we present a program to obtain the optimal sail configuration.We design the wing-tip of the transporter and calculate the lift and drag coefficient,which approximately equals to the testing results.The results of computation and test in wind tunnel show that these wing-tip sails have remarkable effect on reducing induc-ed drag.This method can be used in the initiative design of wing-tip sails. |
