After the amphibious aircraft reduces the take-off and landing speed by increasing the lift, it is necessary to improve the rudder’s handling ability. Using the CFD numerical simulation method, a two-dimensional scheme for the boundary layer control of the tail of a large amphibious aircraft is studied, a seam baffle between the vertical stabilizer and the rudder is designed, so as to prevent the high-pressure air flow on the windward side from hitting the leeward surface, obstructing the air-blowing adhesion. The combined blowing scheme of the leading and trailing edge of the vertical stabilizer surface is studied to prevent the rudder from stall earlier. The results show that the steering ability of rudder is increased by about one times after the vertical tail boundary layer is controlled by a blowing and combined with a seam baffle and a combination of leading and trailing edge blowing.
