| 摘 要： | 本文从点涡和控制点位置的选取出发,研究涡格法中二等分二维平板的升力和力矩的高精度解。发现除传统的1/4和3/4法则之外,还有服从一定规律的无穷多种离散化格式存在,均可以得到精确的升力和力矩。这就为在保证升力和力矩精确的前提下,寻找优于传统涡格法的载荷分布提供了理论依据。

| Abstract: | High-precision solutions of the vortex-lattice methodfor lift and moment of a two-dimensional halving plate are studied bymeans of the choice of the positions of point vortices and control points.It is found that the high-precision lift and moment can be obtainedfrom infinite kinds of the positions of point vortices and control points,which obey a general principle including the conventional 1/4 and 3/4principle.So that it is possible to improve the load distributions givenby the conventional vortex-lattice method on the premise of the high-precision lift and moment. |
