Description

The accepted method of inspecting composite aircraft and engine components is ultrasonic testing with a C-scan presentation of results. Within the last few years, analog recording systems have been superseded by digital data acquisition and analysis. Programmable control of mechanical scanning has improved upon earlier machines which could test only simple flat and circular shapes. The equipment described here was designed to inspect complex profiles such as aircraft engine vanes and ducts. A unique dual-bridge design with synchronized eleven-axis motion control was used to achieve this. The success of the system resulted from careful definition of initial design, and from the use of high-level software to supervise the otherwise lengthy task of programming complex scanning profiles.
