For the performance requirements of reconnaissance and strike integrated system,this paper proposed a aerodynamic configuration scheme of variable-span wing morphing aircraft, and analyzed the design methodology and aerodynamic characteristics based on aerodynamic computation, wind-tunnel test and scaled model flight research works.Veriifed the design idea which requires high lift-to-drag ratio and long endurance on unfold state, small resistance and good lfeche performance on fold state. Generally, the result of the research works indicates that the variable-span wing concept satisifes the requirement of hunter-killer aircraft well, and has a broad application prospect.
