Interference Analysis of Rotor and Wing of Compound Vertical Takeoff and Landing Fixed Wing UAV

Abstract

The composite vertical take-off and landing fixed-wing UAV(Unmanned Airial Vehical) is a compound UAV with the performance of multi-rotor UAV and fixed-wing UAV, the aerodynamic interaction between rotor and wing of this kind of UAV is complex, and its rotor installation location is of influence on the overall performance of UAV. the aerodynamic characteristics are analyzed by experiments and computational fluid dynamics(CFD). The installation mode of the rotor is determined preliminarily, and the installation distance of the rotor is further determined in combination with the level flight status of the UAV. The results show that the hover efficiency of the UAV is higher when the rotor is installed under the wing than that above the wing, and the best installation distance with the lowest power consumption can be found by combining the hover time and flight time of the UAV.
