| 摘要: |
| 采用面元法研究了翼面压力分布和关节数量之间的关系,同时也研究了后缘偏角、俯仰力矩系数和转轴力矩随着后缘关节数量的变化规律.计算结果表明:后缘的关节数越多,相对偏转角越小,翼型表面曲率的突变程度越低,相应表面的压力趋于平缓;但多关节式后缘无法克服柔性后缘带来的俯仰力矩偏大的问题,而且转轴力矩随着关节数的增加而逐渐增大。 |

| Abstract: |
| The relationship between the surface pressure distribution and the number of joints was investigated by use of panel method.Effects of the number of joints on flap angle,pitching moment coefficient and shaft torque were also discussed.Results show that the relative flap angle will decrease with the increasing number of joints of trailing-edge and the wing surface and pressure distribution tend to be smooth.But the problem that the flexible trailing-edge will cause larger pitching moment can not be overcome by multi-sectional trailingedge.The shaft torque will increase with the increasing number of joints.Relevant research results can provide technical support for flexible trailing-edge designing. |
