摘要
本文综合一组小展弦比边条翼实验研究结果,给出不同展弦比机翼前缘脱体涡系变化,并分析涡绞合及破裂对气动特性的影响。研究表明,侧滑使机翼迎风侧涡绞合推迟,涡提前破裂,背风侧正好相反。侧滑时不对称涡破裂对气动特性影响显著。
In this paper some experimental results for stack wing are summarized. In these results variation of vortex system separeted from the leading edge of wing with different aspect ratio is included, and the influence of bursting and twisting of vortices on aerodynamic characteristics is analysed. Results show that sideslip makes twisting of vortices at upwind side delayed, but bursting of. vortex earlier, on the contrary for the backwind side. The asymmetric vortex bursting is of important effect on aerodynamic characteristics.
