| Abstract: | In this paper, the general motion equation of the unmanned aircraft with consideration of arbitrary variable wind field are outlined and derived, after the necessary characteristics parameters and the engineering models of the variable wind field are introduced and defined. A numerical simulation of unmanned aircraft is completed. The aerodynamic effects of the wind shear and its influence on unmanned aircraft launch process are discussed in detail. |
