VENTILATION APERTURE FOR THE PRESSURE BALANCING FOR USAGE IN THE AIRCRAFT NODE Russian patent published in 2017 - IPC B64D13/04 B64C1/14 F24F7/00 F24F13/08 B64C7/00 

FIELD: aviation.

SUBSTANCE: ventilation aperture comprises a vent and plenty of air-gates located at the ventilation aperture vent. Along with this, every air-gate is situated in a far in advance spaced position from the neighboring air-gate with the space between them. Every air-gate has an aerodynamic shaped section designed with the possibility of the efficiency upgrading of the airflow through the ventilation aperture. Furthermore, every air-gate comprises a forward and a rear surfaces. A forward surface comprises the first flat surface vectored at an angle of the distance from the forward surface of the aircraft node outside area to the rear surface. The first flat surface is designed with a possibility of the input air flow deflection from the ventilation aperture for the entering the ventilation aperture air flux reduction.

EFFECT: guarantee of the pressure balancing in the node without the aircraft resistance increase.
