摘　　要：多块网格方法成功的关键在于网格拓扑的选择和块与决之间的拼接方法。针对真实飞机外形多块网格生成，本文分析研究了翼类和体类部件的各种网格拓扑；论述了翼身组合体的多块网格非结构连续拼接技术；指出连续拼接方法的缺点，以及相应的解决方法；同时，还讨论了分块策略和确保块与块之间网格线完全连续拼接的方法；通过实例进一步阐述了本文工作的另外一些独到之处。A successful implementation of multi -- block grid method depends on the choose of grid topology and the patching method of block grids. Aimed at multi-block grid generation around realistic aircraft configuration, various grid topologies for wing-type and body-type components are analyzed and studied, the disadvantage of C°- continuously patching is discussed, which suggests generalizedly-patched grids. Also discussed are blocking strategies and complete continuity of grid lines between blocks. Other characteristics of this work is illustrated through applications.
