英文摘要	以飞机起降过程中主翼和尾翼产生反向涡系存在相互作用的事实为背景,设计了一套反向双漩涡发生装置。通过改变两涡的位置关系与初始涡强度比值,采用流动显示与粒子成像测速(PIV)技术,对涡系相交不稳定性的作用特性进行了研究。结果表明:小涡的引入改变了主涡原有运动轨迹,合理地引入小涡的位置与小涡的强度,对主涡能量的衰减有明显的促进作用,但它们之间不呈现明显的线性关系;涡空间运动轨迹的分析,对未来完善机场起降控制模型有一定借鉴意义;实验结果也为飞机整体设计提供了一定参考依据,在满足飞行力学的设计基础上,优化整体气动布局对降低飞机尾流强度有显著的影响。; Based on the fact that the main wing and tail would produce counter-rotating vortices in the process of taking-off and landing,a set of double vortex generators are designed.Under two different experimental conditions,in terms of changing the position and initial intensity ratio of the double vortex,the wake vortex development of the test mode is acquired,including flow visualizations and particle image velocimetry(PIV)technology.Research reveals that the introduction of a weaker vortex,with a proper position and initial intensity ratio,would change the main vortex original trajectory and promotes its dissipation.However,it does not present an obvious linear relationship between them.The analysis results of vortex trajectory could be used in improving the efficiency of taking-off and landing in airports,the experiments also provide a reference for the overall design of aircrafts:when the requirement for flight mechanics design is satisfied,optimizing the overall aerodynamic layout will have a significant effect on alleviating the intensity of aircraft wake.; 国家自然科学基金(11072206)~~
