摘　　要：由于高升力复杂的流动、外形、驱动和支撑系统,需要耗费大量时间来计算分析设计的正确性,并且风洞实验的成本较高、试验周期长,且不能完全模拟实际飞行条件的不足。因此,文章提出一种基于参数化的升力面缝隙自动修补技术,主要内容包括:缝隙预处理、参数支撑线构造、内核框架线构造、网格光顺控制、网格正交控制技术等。进行了基于Spider软件平台缝隙自动修补模块"GAPFILL"的研究。通过大量网格生成实例的网格质量和数值计算结果,验证了算法的可靠性和鲁棒性。A brief comparison is made between the common grid generation softwares and the in-house SPIDER software. A new method based on parametric and automatic repairing technology is proposed for the generation of gap mesh of the lifting surface. The construction of parametric support-line,kernel frame-line,smoothing control of grid and the controlling technology of orthogonal grid are included. After a detailed study for all process including mesh generation,computational strategy and data processing,results with good agreement with experiment are obtained. And the reliability and robustness of the proposed algorithm are verified by the results.
