Abstract
An ultrasonic scanning system utilizing a selectively rotatable reflector permitting selective use of multiple transducers mounted around the periphery of a water jet for flaw detection in composite materials.
Claims4
An ultrasonic scanning system comprising:
- a plurality of ultrasonic wave emitting transducers circumferentially disposed about the central axis of said ultrasonic scanning system;
- a rotatable reflector coaxially disposed about said central axis of said ultrasonic scanning system;
- means coupled to said rotatable reflector for selectively rotating said rotatable reflector about said central axis of said ultrasonic scanning system to redirect ultrasonic from a selected one of said plurality of ultrasonic wave emitting transducers along said central axis of said ultrasonic scanning system;
- and,
- wherein said plurality of ultrasonic wave emitting transducers includes a first 5 MHz ultrasonic wave emitting transducer for pulse-echo inspection of graphite composite laminates, and a second 1 MHz ultrasonic wave emitting transducer for through-transmission inspection over an extended dynamic range.
