| 摘 要： | 以DLR-F4模型为基本外形,利用涡格法以诱导阻力最小为原则,优选出了C型翼翼梢几何参数.采用N-S方程数值求解方法,研究了C型翼布局各部件之间的流动干扰机理.针对机翼与翼梢之间的流动干扰产生局部激波和翼梢水平段产生负升力问题,采用C型翼梢翼型优化配置的方法.仿真结果表明,这一方法较好地克服了上述不利干扰,进一步提高了C型翼的升阻性能.

| Abstract: | Parameters of C-wing configuration are selected by a vortex method based on minimum induced drag in allusion to the DLR-F4 model.The fluid interference mechanism among parts of the C-wing is calculated by the CFD method of solving the N-S equations.A shock wave on wing and negative lift on horizontal tip come into being,because of flow speeding up between wing and C-wing tip.The shock wave on wing and negative lift on horizontal tip is overcome by optimization collocation of new airfoil on the C-wing tip.Si... |
