AIRCRAFT PRESSURE COMPENSATION DEVICE Russian patent published in 2017 - IPC B64D37/00 

FIELD: aircraft engineering.

SUBSTANCE: present invention relates to a pressure compensation device for an aircraft, more precisely, to a pressure compensation device for an aircraft element, which includes a combustible material in its inner area. Pressure compensation device (100) is arranged in the element, which contains a combustible material in its inner area. Device (100) compensates pressure between inner area (101) of the element and external atmosphere (102) by continuous primary circulation (300) of the air through main channel (103) in device (110). Channel (103) ensures connection of inner area (101) and outer area (102) of the element containing additional channel (104) of device (100) built in device (100) itself, which provides connection of inner (101) and outer areas (102) of the element. Additional channel (104) in the inner area of the element comprises sheet material (105). In case of interruption of primary continuous circulation (300) of the air through main channel (103) the said continuous circulation will continue due to secondary circulation (400) of the air into inner area (101) of the element. Secondary circulation (400) is able to break sheet material (105) of additional channel (104).

EFFECT: provided are structural and aerodynamic advantages, reduced volume and weight of the system, total cost reduction.
