Abstract
An apparatus for ultrasonically inspecting a component of a gas turbine engine at a centre frequency required for ultrasonic inspection of the component. The apparatus comprises an ultrasonic transducer and a waveguide. The ultrasonic transducer and the waveguide are mounted in a holder, the holder is movably mounted in a carrier, and the carrier is movably mounted in a frame. The waveguide has a first end, a second end and a surface. The waveguide is circular in cross-section, the surface of the waveguide between the first end and the second end is concave, and the waveguide reduces in diameter from the first end to the second end. The length of the waveguide is equal to or greater than 0.5 times and equal to or less than 3 times the wavelength of an ultrasonic signal at the centre frequency required for the ultrasonic inspection.
