摘要： A system and method that allow inspection of hollow structures made of composite material, such as an integrally stiffened wing box of an aircraft. A wing box comprises top and bottom skins connected by a plurality of spaced spars. The system employs a plurality of scanners for inspecting different portions of each spar. The system uses dynamically controlled magnetic coupling to connect an external drive tractor to computer-controlled scanners that carry respective sensors, e.g., linear ultrasonic transducer arrays. A system operator can control the various components by means of a graphical user interface comprising multiple interaction regions that represent the individual scanner motion paths and are associated with respective motion script files.

摘要： Improved apparatus, systems, and methods for inspecting a structure are provided that use a probe having two ultrasonic transducer arrays. This enables simultaneous testing using two different test frequencies. The probe uses pulse echo ultrasonic signals at different frequencies to inspect the structure. The probe includes a support body having a fluid conduit formed therein. The fluid conduit provides flow paths for a couplant (such as water) that is used to couple the ultrasonic signals between the structure under test and the arrays. The fluid conduit is configured to quickly eject couplant and bubbles contained in the couplant.

摘要： A computer-controlled robotic platform with a collapsible lifting arm that positions a non-destructive inspection (NDI) sensor for scanning inside tunnel regions of a composite structure such as an integrally stiffened wing box. The lifting arm of a modified scissor lift mechanism can be collapsed to a very low height to pass through narrow sections of the integrally stiffened wing box, and also extended by more than a factor of three to reach the maximum height of the wing box tunnels. The system performs a vertical position sensing and control process that uses inverse kinematics to enable position control using data from a standard rotational encoder on the motor to determine vertical position. The system produces simulated encoder pulses that represent unit vertical displacements of a distal portion of a modified scissor lift mechanism using a forward kinematics equation in which the rotation angle of a lead screw is an input variable.
