wherein PM is the estimated power capacity of the thrust motor, and n is the total efficiency, including the motor efficiency, the mechanical efficiency (including the friction loss), and the propeller efficiency. The calculation results are shown in Table 4 when the total efficiency was reduced to 0.4. To achieve more than the maximum design speed, an 80-watt BLDC motor with a reduction gear with a 5.8:1 gear ratio (made by Maxon Motors) was selected as the thruster motor. The selected propeller for the thrust system was KP452 S175, from the KORDI propeller series.
