WING AND METHOD FOR IMPROVING CONTROL EFFICIENCY OF TWO-DIMENSIONAL AIRFOIL RUDDER SURFACE

WIPO Patent Application WO/2023/109154

A1

Disclosed are a wing and a method for improving control efficiency of a two-dimensional airfoil rudder surface. According to the technical solution, an original symmetric airfoil rudder surface is transformed into an asymmetric airfoil rudder surface, the asymmetric airfoil rudder surface and a main wing are mounted in a staggered manner to form a gap, flowing of an upper wing surface of the rudder surface is disturbed by means of a gap effect, so that torque generated by the rudder surface is increased, thereby improving the control efficiency of the two-dimensional airfoil rudder surface. According to the present invention, the rudder surface control efficiency is greatly improved by means of simple structure optimization; a pilot is convenient to operate in the control process; a control apparatus utilizes parts of an aircraft, does not need to introduce a driving device such as a large power source, and does not increase a loading burden of the aircraft.
