摘　　要：采用三维加权网格对发动机复杂三维模型进行网格划分,描述敷管的自由空间,在此基础上利用改进的Lee算法以及最小斯坦纳树生成法,结合各种启发式规则,开发出航空发动机网格敷管系统(AEGRS)。并通过实例,验证了自动敷管的可行性。By adopting 3D weighted grid to carry out grid differentiation on complicated 3D model of engine and to describe free space of pipeline laying out.Taking this as a base and by the use of improved Lee algorithm and the least generative method of Stanner tree,and by combining with various kinds of heuristic rules the Aero-Engine gird based Routing System(AEGRS) was developed.The feasibility of automatic laying out of pipeline is verified by means of living example.
