Abstract

The device has an aerodynamic element (5) arranged upstream of a front trap door (3) and deflecting flow of air on a level of a front landing gear (2). The landing gear is equipped with the front trap door and a rear trap door (4). The aerodynamic element is formed in manner such that the element realizes deflection of the flow between 20 and 50 percent. The aerodynamic element corresponds to a metal bar (7) that is fixed on its sides on a fuselage (6) of an aircraft (AC).
