The system consists of at least two elongated and flattened aerodynamic members (1, 2), parallel to each other as well as at least one thin plate (3) placed between the members (1, 2). The members are shaped as elongated planes (1, 2) with aerofoil profile cross-section. The distance (H) between the plate (3) and chord of each plane is constant and ranges between 5 % and 50 % of mean length of this plane's chord. |
