FIELD: aircraft.
SUBSTANCE: invention relates to the actuating devices of control systems of aircraft with aerodynamic quality. The control surfaces are installed on the section of the aft part of the aircraft hull and are made in the form of composite shields, on the end part of each of which an aerodynamic grille is installed. The lower plane of the lattice plan is set at an angle of 5…10° to the plane of the shield, and the upper plane of the plan is rotated relative to the lower one by an angle of 3…7° . The flap plane is bounded by side walls with a height from zero in the flap root part to a height equal to the grating pitch in the flap end part at the aerodynamic grille junction.
EFFECT: increased efficiency of the aircraft control system (by 34…44% for 3-channel control) while ensuring a continuous flow around the aircraft body in the area where the shields are located.
