Key technique and aerodynamic configuration characteristic of UCAV with command of the air

UCAV with command of the air (UCAV-CA) is considered to be an important development branch for fighter planes or UCAVs in the future. This paper analyses the technical characteristic of UCAV-CA, and points out its two development routes, one is fighter plane unmanned and the other flying wing UCAV updating. And then, the technical and tactical demands and key techniques of UCAV-CA are studied. Furthermore, two important aerodynamic configurations including flat blend wing body with middle/small aspect ratio and flying wing body with middle/big aspect ratio are concluded, and one possible aerodynamic configuration which has (duck style) flying wing body with middle/small aspect ratio is present. Finally, the design demand to UCAV-CA of aerodynamic configuration is summarized, which is expected to bring some suggestions for designers.
