摘　　要：以DPW4的CRM模型为例,给出了一种复杂外形飞行器网格生成的分块对接网格拓扑方案以及实现过程,在无限插值法生成的初始网格基础上,用椭圆微分方程生成空间网格。基于该网格求解N-S方程,获得了较为合理的全机气动力系数与压力分布。Taking CRM model of DPW4 as an example,and a topology project and the realization process for multi-block patched grid were given to generate the grid of A/C with complicated shape.On the basis of initialization grid generated by TFI method,the spatial grid was generated with elliptic differential equation.And N-S equations was solved on the basis of the grid for obtaining the reasonable aerodynamic coefficients and pressure distribution of whole A/C.
