Efficiency of rotor blades for drones with high thrust guide

One of the methods to improve the thrust of a drone rotor is to attach an external guide composed of a bottom plate and cylindrical side plates around the outer circumference of the rotor blades. Although its thrust force has been studied in previous research, its efficiency as a thrust system is still unknown. In this study, the efficiency of the thrust system is evaluated from the thrust force and power consumption of the thrust system. Experimental results show that the thrust increases by 15% and the power consumption per rotor power decreases by 7%. The “figure of merit” (FM) also increases by 0.1 with the addition of the external guide.
