About
Wolfgang Hillger is a pioneering figure in the field of non-destructive testing, with his research centered on advancing air-coupled ultrasonic techniques for industrial inspection. His major contributions lie in overcoming the fundamental challenge of acoustic impedance mismatch between air and solid materials, developing specialized transducers, powerful excitation systems, and sophisticated signal processing to make air-coupled ultrasonics practical and reliable. His work has had a profound impact on aerospace quality assurance, as demonstrated by his highly cited paper on the automated inspection of the EC145 tail boom, which has garnered 5 citations. This study notably replaced traditional water-coupled "squirter" methods with a non-contact alternative, eliminating issues like pressure variations, air bubbles, and corrosion. Hillger’s development of the USPC 4000 AirTech system, detailed in his 2014 paper with 6 citations, represents a landmark achievement, providing a robust, automated solution for complex composite structures. His research not only solves long-standing practical problems but also sets new standards for efficiency and reliability in aerospace manufacturing and maintenance.
