Abstract
A device for testing a stiffener of an aircraft structure made from composite materials. At least one ultrasound sensor is configured to provide measurements relative to a material health state of the stiffener. The device includes a protective enclosure for housing the ultrasound sensor and a mobile gantry configured to move along the stiffener. The protective enclosure with the ultrasound sensor is mounted inside the mobile gantry. A driver is configured to drive the mobile gantry along the stiffener. A clamper is rigidly connected to the protective enclosure and configured to hold the ultrasound sensor pressed against the surface of the stiffener to be controlled. A locator to synchronize each area of the surface of the stiffener with the measurement of the ultrasound sensor.
