Claim:
An apparatus for non-destructive inspection of a structure, comprising: a support body; a first ultrasonic transducer array coupled to a first portion of the support body and configured to inspect the structure at a first frequency as the support body is moved over the structure; a second ultrasonic transducer array coupled to a second portion of the support body and configured to inspect the structure at a second frequency as the support body is moved over the structure; and a fluid conduit formed within the support body and configured to simultaneously disperse a couplant between a first longitudinal flow channel corresponding to the first ultrasonic transducer array and a second longitudinal flow channel corresponding to the second ultrasonic transducer array, wherein the first longitudinal flow channel and the second longitudinal flow channel are parallel and non-colinear, and wherein a fluid inlet is located between the first longitudinal flow channel and the second longitudinal flow channel.
