| 摘 要： | 针对飞机表面压强系数Cp值的计算,讨论定义在三维空间R3的二维流形 Σ上的散乱数据插值问题,利用映射与加权混合相结合的技术,给出了能与柱面Σ0同胚的任意物体表面Σ上的散乱数据插值算法,通过此算法所得的插值函数能达到C1连续。将此算法应用在飞机表面Cp值分布曲面的重建问题上,得到了很好的效果。

| Abstract: | In order to solve the problem of calculation of Cp surface on surface of aircraft, the authors discussed the problem of interpolating scattered data located on a 2-manifold in 3-D space. An algorithm for interpolating scattered data located on an arbitrary surface Σ which is topologically equivalent to a cylinder Σ0 is given, which reconstructs a C1 function on the surface Σ by using mapping and blending technique. With the application of the algorithm into the reconstruction of Cp surface on surface of aircraft on the condition of fixed angle of attack and Mach number, good results have been gotten. |
