Method for producing a closed-section portion of an aircraft provided with deformation sensors

摘要

Method for producing a closed-section portion of an aircraft wherein a strain gauge (17) is glued on a first face (15a) of a flat tape (15) that is previously fastened on a face (11a) of a tool (10) comprising a rigid elongated body covered by an extensible sack (12). The tool (10) supporting the tape (15) is arranged in a cavity (7) of an aircraft structure. Vacuum is then created to obtain the expansion of the vacuum sack (12) and perform the pressure gluing of the tape (15) onto a wall of said cavity (7). The tool (10) is subsequently extracted from the cavity (7). As a result of these operations, the tape (15) is integrally fastened onto a wall of the cavity (7) so that any deformation applied to this wall is transmitted to said strain gauge (17).
