For the past several years, the aviation industry has seen above normal growth due, in part, to lower oil prices, saving major aircraft operators millions of dollars. As a result of this growth, production rates for new airplanes have increased, and new aircraft programs are being launched. Consequently, aviation component manufacturers are facing new challenges, including a rise in production rates, a high probability of detection (POD) due to the critical nature of the parts being manufactured, lack of skilled operators, and parts with increasingly complex geometry. Ultrasonic phased array (PA) instruments have evolved, enabling the implementation of advanced acquisition strategies. The introduction of these acquisition strategies helps manufacturers address the inspection challenges they are facing. The evolution of electronic components enables advanced acquisition strategies, such as adaptive focusing, to be implemented. Adaptive focusing simplifies the inspection of variable radiuses, variable opening angle, and twisted components, and will also compensate for probe misalignment by using innovative signal-processing algorithms. This paper presents an overview of the adaptive focusing technology with the goal of helping NDT integrators and composite material manufacturers to address the challenges they are facing in terms of system performance, production output, and quality control.
