With the dramatic increase in composite structures on rotorcraft, damage to composite structures in service has also increased. Prior efforts established that field level repair requires field level non-destructive inspection. This Army program provides field level non-destructive inspection capability, making this capability as user-friendly as possible, with minimal training requirements. Detail development of the system has been completed, and incorporates several inspection methods: ultrasonics (pulse-echo and time-of-flight), resonance, and eddy current. The system is being tailored to the Army maintenance environment and to reduce inspector training and experience requirements. A working prototype has been available for several months. Under an optional phase of the program, expert systems and artificial intelligence will be used to improve the usability of the system, and further reduce the training and experience requirements.
