气动电磁学概念探讨及若干研究进展介绍

Discussion about the concept of aero-electromagnetics and introduction of typical research progress

目前国内外一些热点研究方向,如再入/临近空间高超声速飞行器电磁散射特性、通信中断、气动隐身一体化、等离子体隐身、等离子体流动控制和电磁推进研究,既涉及到空气动力学又涉及到电磁学,形成气动电磁学这一交叉领域。本文从概念定义、典型应用领域、主要机理问题、试验设备和测量仪器等方面对气动电磁学进行了探讨。建议在基础理论、数值模拟、试验设备与测试技术等方面加大气动电磁学研究力度,促进气动电磁学在航空航天领域的应用。

Both aerodynamics and electromagnetics are involved during the research on some hot issues of aeronautics and astronautics problems,which include target characteristics of reentry or near space vehicles,reentry radio frequency(RF)blackout,integrated aircraft design of aerodynamic and stealthy performance,plasma stealth,plasma flow control,electromagnetic propulsion,and so on.These issues are stated as aero-electromagnetics uniformly in this paper.The concept,applied fields,main mechanisms,and test facilities of aero-electromagnetics are discussed.Typical research progresses on this topic of our group are introduced.Some suggestions are given for the research regarding fundamental theories,numerical simulation,test facilities and test methods to enhance the applications of aero-electromagnetics in aeronautics and astronautics research.
