民用飞机增升装置中的流动控制技术

传统的增升装置设计受到各种约束条件的限制，难以充分发挥增升效果，甚至无法达到飞机对增升效果的需求，而流动控制技术可以弥补这些缺陷。通过搜集大量文献，阐述了襟翼涡流发生器、主翼后缘偏折技术、ZHU’s襟翼、自激励运动襟翼、零质量射流、等离子体技术、MEMS技术以及动力增升等各类主动控制技术的工作原理，增升效果分析以及具体应用情况等。结果表明，这些流动控制新技术对于进一步提高民用飞机的增升效果具有巨大的潜力。

Flow Control on High-Lift Devices of Civil Aircraft

Conventional high-lift devices design is limited by many factors,so lift enhancing can not be obtained sufficiently,and then,it can not meet request on lift enhancing of aircraft.However,flow control can make up the shortage.In this paper, many kind of flow control is introduced from work principle,lift enhancing efficiency and the application by consulting much information.The flow control includes vortex generators on flap, spoiler deflected,ZHU's flap,self-activated movable flap,zero mass actuation,plasma actuators, MEMS technique, dynamical lift enhancing, and so on. The analysis results indicate that these flow control technique has great potential for improving lift enhancing efficiency of civil aircraft.
