The hovercraft's inner and outer ring-type air propeller uses an asymmetric air rudder. Three rudder blades are arranged side-by-side relative to the air propeller. The cross-sectional shape of the rudder blades is that of an aircraft airfoil, with the middle blade being the positive rudder blade aligned with the direction of the lateral drift force, and the two outer blades being the counter-rotating rudder blades opposite to the direction of the lateral drift force. This type of hovercraft's inner and outer ring-type air propeller uses an asymmetric air rudder, whose blades are essentially vertical airfoils. Airfoils generate lift at positive angles of attack, but generate little or no lift at negative angles of attack, having little impact on navigation. Therefore, through the shape and orientation of the three rudder blades, the lateral drift force generated by the air propeller can be counteracted when the hovercraft is sailing upright, effectively improving the hovercraft's stability. Furthermore, the lift difference between the rudder blades can be used to provide sufficient steering force during turns.
