摘要
Abstract
Numerical simulation is carried out to calculate and analyze the aerodynamic interaction be-tween the front rotor /fuselage /rear rotor during the tilting and transition state of the cross shaped four-rotor UAV.The calculation models of isolated front rotor,front/rear rotors,front rotor /fuse-lage,and front/rear rotors fuselage combination are established.Numerical calculation and analysis of aerodynamic force and aerodynamic torque of the front rotor /fuselage /rear rotor at the different an-gles of rotor tilting are proposed.It is concluded that the front rotor is the leading factor in the aerody-namic interference of the whole UAV in the front rotor/fuselage and front/rear rotor fuselage combina-tion.It provides the theoretical guidance for the design and optimization of the configuration of this kind UAV.关键词
