| Abstract: | In this paper, the general equations of motion of the aircraft with consideration of arbitarily variable wind field are outlined and derived, after the necessary coordinate frames and Euler angles are introduced and defined. Two systems of equations obtained are suitable for numerical simulation of the aircraft three-dimensional flight in turbulence and wind shear. The aerodynamic effects of the wind gradient are discussed in detail. |
