BALLOON ASSEMBLY AND CORRESPONDING SYSTEM AND METHOD OF HOLE ALIGNMENT Russian patent published in 2021 - IPC B23P19/10 B32B27/08 F16B17/00 

FIELD: aircraft construction.

SUBSTANCE: invention relates to a method (300) for aligning the first hole (110) with the second hole (124) in a system (100) for aligning holes, which contains the first element (102) defining the first hole (110) having the first central axis, the second element (104) defining the second hole (124) having the second central axis, and the specified second central axis is offset relative to the specified first central axis, a balloon assembly (10) containing an inflatable balloon (12) containing a housing (30) that defies an internal volume (31), and a source (14) of a fluid under pressure, designed to selectively communicate through the fluid with the specified internal volume (31), and the system (100) contains a vibrator (106) placed to impart vibration to the specified first element (102) and/or the specified second element (104). The method (300) includes placing an inflatable balloon (12) with its passage through the specified first hole (110) and second hole (124) and cyclically increasing the pressure in the specified inflatable balloon (12) using a fluid from the fluid source (14), causing the expansion of the specified inflatable balloon (12) and entering it into interaction with the specified first element (102) and the specified second element (104), and cyclically vibrating of the specified first element (102) and/or the specified second element (104) using the specified vibrator (106) until, after or simultaneously with a cyclic increase in pressure.

EFFECT: reduced wear of the first and second elements.
