Abstract: The invention relates to a tool for non-destructive inspection of a three-dimensional wall, the tool including a plurality of juxtaposed non-destructive inspection sensors. The sensors are mounted on a support for moving the set of sensors in common relative to the wall. The support is deformable for each of the sensors so that the sensors are movable relative to one another. Also provided are a constraint element for constraining the application face of each sensor to press individually against the wall and a sliding element for causing the application face of each sensor to slide against the wall.
