METHOD TO GLUE ELEMENTS FOR AIRCRAFT WITHOUT APPLICATION OF AUTOCLAVE Russian patent published in 2011 - IPC B64C1/12 B64F5/00 

Abstract RU 2425778 C2

FIELD: construction.

SUBSTANCE: adhesive film (16) is applied in the area of points (15) of connection of stringers (13) and a lining panel (14), besides, the adhesive film (16) is arranged in the form of a carcass fabric impregnated with epoxide resin. Then stringers (13) and lining panels (14) are placed and balanced relative to each other on a support structure (7), and balanced stringers (13) and the balanced lining panel (14) are covered with a vacuum film (11, 18) to produce a vacuum bag (12, 28). At the same time the vacuum film (11, 18) is applied directly onto stringers (13) and the lining panel (14), designed for glueing with each other. Afterwards partial vacuum is pulled with pressure Pinternal in the vacuum bag (12, 28) for application of sufficient contact pressure to stringers (13) and the lining panel (14) with the help of ambient air pressure Pambient and hardening of at least one adhesive film (16) for final adhesion of stringers (13) and the lining panel (14) to each other, besides hardening of at least one adhesive film (16) is carried out at the temperature, which is higher than room temperature.

EFFECT: simplified process of glued joints manufacturing.
