In-situ Ultrasonic Surface Wave Detecting Technology Used Compressor Blade

In-situ ultrasonic surface wave detection used the low-pressure compressor blade of a engine was achieved by using portable ultrasonic flaw detector, special tool and surface wave probe which was especially made. Ultrasonic surface wave detecting rule of coated blade was found by theoretical calculation and experimental validation. Influencing factors of ultrasonic surface wave detecting technology used blade were summarized.
