涵道式垂直起降固定翼无人机过渡走廊研究

The accurate description of the transition corridor is important for vertical take-off and landing（VTOL）fixed-wing unmanned aerial vehicle（UAV）flight. In order to study the transitional flight process of VTOL fixed-wing UAV，a transition corridor model of this type of UAV is established in this paper. From the perspective of flight dynamics，the deflection angle-speed envelope of the power system is studied by means of the maximum lift coefficient of the wing and the system available power limit. The influence of the overall parameters and energy pa⁃ rameters of the UAV on the deflection angle-speed envelope of the power system is analyzed，and a method to ex⁃ pand the transition corridor of the vertical take-off and landing fixed-wing UAV is proposed. Through case calcula⁃ tions，the transition flight corridor is obtained. The results show that the established deflection angle-speed enve⁃ lope can perfectly describe the transition flight corridor of VTOL fixed-wing UAV，the 10% increasing of the avail⁃ able power can expand the transition corridor by 21.43%，while the 10% increasing of the aerodynamic parameters can only expand the transition corridor by 2.33 %.
