摘　　要：基于MD-30P30N多段翼型反构建干净翼型,利用FLUENT软件,对该翼型前后缘无缝偏转进行研究,包括前后缘比例和偏角在无缝偏转中对增升效果的影响;针对无缝偏转引起的后缘大迎角气流分离,采用环量控制技术(后缘主动喷气)进行改善,并研究了喷气动量系数及喷口高度的影响。最后在多学科优化软件ISIGHT中,对上述参数采用基于响应面的多岛遗传算法进行整体优化。结果表明,该无缝增升系统能达到与MD-30P30N多段翼型相当的升力要求,具有一定的工程应用前景。The seamless high-lift technology is a rising direction which is adapted for the reason of envi- ronmental requirements concern. A clean airfoil based on MD-30P30N multi-element airfoil is built, research on seamless deflection at leading and trailing edge, including parameters of deflection proportions and angles are investigated using the software of FLUENT. Circulation control technique （active trailing jet） is adopted to eliminate the trailing edge flow separation at high angle of attack, and the momentum coefficient and noz- zle height are studied at the same time. Using the multi-discipline optimization software of ISIGHT, the multi-parameter optimization is also carried out based on the optimized response surface, in which the Multi- island genetic algorithm is adopted. The results show that, the equivalent high-lift capability could be achieved compared with that of MD-30P30N. The possible value in engineering application of this method is validated.
