Wing Skin Topology Verification

Two vertical towers made from composite materials were secured to a common bed that could traverse the length of the skin panel. Each tower has distance sensors that move vertically on a servo rail. Since the combined inaccuracies of the overall traversing structure and the measurement system must be less than 0.02 inches, the solution needs real-time knowledge of each tower’s pitch and roll relative to long X scan axis, which is then added to previously mapped relationships. Redundant multipoint information is obtained at different angles, then averaged together to obtain one reading.
