ULTRASONIC SCANNING DEVICE HAVING A FLUID PAD

摘要

An ultrasonic scanning device for scanning a turbine component. The device includes an ultrasonic transducer attached to a moveable fluid distribution block, wherein the block includes a block opening and an internal passageway for receiving a fluid. The device also includes a fluid pad having a fluid pad opening that is in fluid communication with the block opening, wherein the fluid pad and block openings form a channel that extends between the ultrasonic transducer and the turbine component. Fluid received by the internal passageway moves to the channel and forms a fluid column between the ultrasonic transducer and the turbine component that facilitates transmission of ultrasonic energy generated by the ultrasonic transducer. In addition, the device includes a control module for controlling operation of the ultrasonic transducer and an encoder for providing travel information to the control module for determining a position of the device relative to the turbine component.
