METHOD FOR ADHESIVE REPAIR OF AERODYNAMIC SURFACES OF AERIAL VEHICLES Russian patent published in 2021 - IPC B29C73/26 B29C73/10 

FIELD: aircrafts.

SUBSTANCE: invention relates to the technology of repairing aerodynamic surfaces of aerial vehicles made of polymer materials. A method for repairing aerodynamic surfaces of aerial vehicle made of polymer materials, wherein a perforated drainage tube is installed on the aerodynamic surface in the repair area, on top of a vacuum bag consisting of patch layers impregnated with an adhesive composition, on top of said layers, in addition to the technological package, using two or more layers of a sealing bundle, and a vacuum bag shell is attached using a sealing bundle, wherein air is removed from under said bag using a vacuum pump, and technological pressure is applied due to the difference between the atmospheric pressure outside of the vacuum bag shell and the created underpressure under the vacuum bag shell, after the patch layers are compressed under the impact of vacuum pressure, an air bag made of rubberised fabric is installed on top of the vacuum bag in a metal box, providing additional technological overpressure of a predetermined acceptable value in the repair area and in combination with the vacuum bag providing optimal content of the adhesive composition in the patch layers and compaction of the patch layers contributing to increasing the connection strength.

EFFECT: technology of repairing aerodynamic surfaces of aerial vehicles made of polymer materials.
