Title:
WING, AND METHOD FOR IMPROVING CONTROL EFFICIENCY OF RUDDER BY MEANS OF AIR BLOWING
Document Type and Number:
WIPO Patent Application WO/2023/221310
Kind Code:
A1
Abstract:
Disclosed in the present invention are a wing, and a method for improving the control efficiency of a rudder by means of air blowing. In the technical solution of the present invention, an original symmetrical airfoil rudder is deformed to an asymmetric airfoil rudder, air is blown via an air-blowing hole in the end portion of a main wing that is adjacent to the rudder, and an airflow that flows through an upper wing surface of the rudder is controlled, such that a separation flow of the rudder is transformed into an attachment flow, thereby improving the control efficiency of the rudder. By means of the present invention, the control efficiency of a rudder is greatly improved by means of simple air blowing; the operation is simple during the control process of a pilot; and a control apparatus has a simple structure, and only a small-sized air source apparatus needs to be introduced, without increasing the loading burden of an aircraft.
