摘　　要：有效抑制机翼的流动分离可以提高飞机的起飞、着陆性能,优化民用运输机增升构型的低速特性。通过风洞试验开展对翼身融合鼓包和发房外导流片这两种被动控制技术的选型研究,找到能优化低速特性的最佳组合方案——小翼身融合鼓包叠加外发房导流片A,并通过流动显示试验呈现出优化手段所抑制流动分离的区域。结果表明:在最佳组合方案条件下的力矩特性满足波音准则的要求。In order to optimize the low-speed characteristics of the high-lift configuration of civil transport aircraft and enhance the take-off and landing performance of the aircraft,it is necessary to control the flow separation of the wings.Through the wind tunnel test,the research on the selection of two passive control technologies,the wingbody fairing and outboard nacelle strake,is carried out.The best combination scheme that can optimize the lowspeed characteristics is found:small size wing-body fairing plus outboard nacelle strake"A";the area where the flow separation is suppressed by the optimization method is presented through the flow visualization test.The pitch moment characteristics under the conditions of the optimal combination scheme meet the requirements of Boeing cri-teria.
